Dilutions Cheat Sheet for Dr. Bronner’s Liquid Castile Soap

castile soap

Update May 2022 —I’ve added a few uses to both the Sal Suds and Castile Soap Cheat Sheets. Plus: All four Cheat Sheets are now available in Spanish! (See the side bar to download or print.)

Dilute! Dilute! OK!* But how much? Here is a quick reference. None of this is a hard and fast rule. If your stuff is really dirty or your water is really hard, then you may want to use more than the recommended amount. However, this should get you started. You’ll notice that for some applications, I recommend pre-diluting the Dr. Bronner’s Liquid Castile Soap—combining the soap with water in a container. For other applications, the soap is diluted by the water present in the situation. It’s a matter of personal preference. Keep in mind that if you predilute, you are also diluting the preservation system (tocopherols – vitamin E), so the shelf life drops. Use within a couple weeks. And yes, there are 18+ uses here.

* Long time Dr. Bronner’s users will remember this expression from the old labels.

Body Uses

Face: 2-3 drops on wet hands, applied to wet face.

Body: One small squirt on wet hands or washcloth, applied to a wet body.

Foaming Pump Dispenser: Dilution of one part soap to 3 parts water.

Wipe-Off Castile Body Wash Spray: Use when running water isn’t an option due to illness, large cast or bandage, or when hiking, camping, etc. Combine 1 ½ tsp. (7.5 mL) soap and 1 c. (240 mL) room temperature water in a spray bottle. Spray body wash lightly on skin, and wipe with a wet (not dripping) cloth. Dry skin.

Makeup Removal: Wet face and lather several drops of soap into hands. Massage into skin. Rinse.

Hair: A couple drops for close-cropped hair or up to ½ Tbsp. (7.5 mL) for long hair, either worked directly into very wet hair or pre-diluted in a cup of water. Follow with a capful of Dr. Bronner’s Citrus Organic Hair Rinse diluted in one cup (240 mL) of water or dilute apple cider vinegar in half with water.

Bath: Completely depends upon water amount, but approximately 2 Tbsp. (30 mL) soap in an average sized tub. (Doesn’t bubble, but still cleans.)

Shaving: Face—10 drops; Underarms—3 drops; Legs—½ tsp (2.5 mL); Work to a lather in wet hands, apply to area.

Teeth: 1 drop on a toothbrush. (Yes, it tastes like soap.)

Oral Appliances: Removable retainers, nightguards, etc. & dentures: Wet device. Add 1-2 drops of soap to a soft toothbrush. Brush gently, then rinse.

Foot Bath: ½ Tbsp. (7.5 mL) in a small tub of hot water.

Clearing Congestion: 1 Tbsp. (15 mL) Peppermint or Eucalyptus Castile soap in a bowl of steamy hot water. Breathe in mist with a towel draped over the head.

Household Uses

Dishes (Handwashing): Pre-dilute 1:10 with water. Squirt on a scrub brush. Alternatively, add 1-2 Tbsp. (15-30 mL) Castile Soap in a large sink of water. Use a small squirt of soap for one pot, or more if needed. To avoid water spots in hard water conditions, dry dishes by hand.

Laundry: 2–4 Tbsp. (30–60 mL) for HE washers. Add ½ c. (120 mL) vinegar to the rinse cycle. Optional: For whitening/deodorizing, add ¼ c. (60 mL) baking soda to wash cycle. Double these amounts for standard washers.

Handwashing Delicates: 1 capful (1 Tbsp. or 15 mL) Castile Soap in about 1 gallon (4 L) cold water. Swish gently. Let soak 10 minutes. Swish again. Rinse with clean water. Gently press out excess water with a towel. Hang or lay clothing flat to dry.

Mopping (Wood, Laminate, Vinyl, Stone & Tile Flooring): 2 ½ Tbsp (38 mL) of soap in 1 gallon (4 L) of hot water. Dunk mop (microfiber, preferably) and wring thoroughly. On wood and laminate, avoid excess water and mop up wet areas.

For smaller areas, add 2 tsp. (10 mL) Castile Soap to a quart (1 L) of water in a squirt bottle.

All-Purpose Cleaning Spray: 2 Tbsp. (30 mL) soap in 16 oz. (500 mL) water. Spray and wipe with a damp cloth. Optional: For extra microbial punch, add ¼ tsp. (1.25 mL) tea tree essential oil. Use on any surface that is safe in contact with water-stone countertops & tile; wood (painted or sealed, not waxed); plastic toys and such; stainless steel; sinks & toilets; and more!

Windows: ½ Tbsp. (7.5 mL) soap in 16 oz. (500 mL) water. Spray and squeegee. Follow up with pure club soda, or half vinegar/ half water and squeegee.

Toilet: Predilute 1:4 with water in a squirt bottle. Add ¼ tsp. (1.25 mL) tea tree oil. For best results, empty toilet. Spray or squirt 2-3 drops of Castile Soap directly on toilet brush. Sprinkle baking soda on the brush, scrub bowl, let sit 10 minutes, turn water on, flush.

Other Uses for Liquid Castile Soap

Fruit & Veggie Wash: 1 dash (approx. ¼ tsp.) in a bowl of water. Dunk produce and swish. Then rinse in clear water.

Dog Washing: Wet dog thoroughly. Massage in enough soap to create a good lather. (Amount varies based on size, hair type, and overall dirtiness.) Really massage it in down to the skin. Your dog will thank you for it. Rinse thoroughly.*

Cleaning Makeup Brushes: Wet the make-up brushes in water. Add 1-2 drops soap to the bristles. Massage in gently for 10+ seconds, then rinse. Repeat as needed until water runs clear.

Plant Spray for Bugs: 1 Tbsp. (15 mL) in a quart (1 L) of water. Optional: Add ½ tsp. (1.25 mL) cayenne pepper or cinnamon. Spray plants twice daily in the cool of the day until infestation clears.

Ant Spray (Not on plants): ¼ c. (60 mL) Tea Tree Castile Soap in a quart (1 L) of water. (This concentration will burn plants.)

I’ve tried to keep this short and sweet. If you have any questions, please ask away!

Emily says:

What would you recommend I use as a hair care routine of your products? I have short medium brown hair that I don’t color and is wavy and very healthy, although I do swim in chlorine pools frequently for exercise and as a competitive sport a couple months out of the year. Thanks!

Lisa Bronner says:

Hi Emily – My favorite regimen is the Pure Castile Soap – wash and rinse – and then follow up with a 50% apple cider vinegar rinse. As far as specific scent, I generally find the Peppermint too drying for me, so one of the medium ones such as Almond or Citrus smell and feel fantastic.

Zelda Haro says:

I would like to start making my own baby wipes what do you recommend as a solution mixture ?

Lisa Bronner says:

Hi Zelda – I missed the boat on this one and never made my wipes when my kids were babies. However, my exceedingly talented sister-in-law Erin Bronner just did and I will post her recipe soon. Stay tuned.

elizabeth batista says:

Hi Lisa

I would like to use the peppermint Castille soap to combat pests …can u suggest a dilution to use to spray around the house and do house cleaning

Dr. Bronner's Almond Pure-Castile Liquid Soap Review - Chantal's Corner says:

[…] I didn’t realize you could do so many things with this soap! They list a few on the bottle and you can visit their website for the rest of the uses. […]

Davina Howard says:

Is it mandatory to put vinegar in the rince cycle while doing laundry.

Lisa Bronner says:

Hi Davina – No, it is entirely up to you. If you find your clothes feel stiff after washing, the vinegar will help as a fabric softener. It’s really only noticeable in very hard water.

Miriam says:

I want to make handsoap out of the Baby Dr. BRONNERS Castile soap. What should my dilution be and do I need to add coconut oil or any other oil to it or essential oil like some other Castile hand soap recipes ?

Lisa Bronner says:

Hi Miriam – In a foaming pump dispenser, a dilution of 1:3 with water works well for hand soap. I don’t add anything else to mine. Bear in mind, as the bottles say, do not put the soap, even diluted, into a regular pump dispenser.

February Beauty Favorites – Marie Mad Fitness says:

[…] Dr. Bronner’s Pure Castile Soap – This soap has so many uses, personally I use it as face wash and for cleaning my makeup brushes. I’ve also used it for shaving and hand washing my bathing suits. You can even rinse fruit and veggies with it. Read about more uses here.  […]

jc says:

can you use this as a feminine wash like after peeing? dilution? does it have to be rinsed

Lisa Bronner says:

Hi JC – The soap is definitely mild enough for a feminine wash, but should be rinsed.

Jacquiline says:

Hello! I use Carol’s Daughter Monoi shampoo and conditioner on a regular basis. I only use coconut oil in my hair to style/hydrate after washing. I tried the light blue soap in my hair and was left with a very stiff and tacky result. I want to love this soap as much as everyone else does, but I don’t know how to use it to clean my hair. It was actually my first time ever using the Dr. Bronner’s on my hair when this happened. My hair is naturally curly and fine, and curl sizes vary from large spirals underneath to small kinks and frizz on outside. I am Spanish/Portugese with my Polish mom’s fineness. Any help you can give is appreciated. Thanks!

Lisa Bronner says:

Hi Jacquiline – Your hair sounds beautiful. Switching to Dr. Bronner’s for hair care may be the trickiest of all transitions. I wrote about my own experiences here: https://www.lisabronner.com/?s=shampoo+to+soap. One key is that you’ll definitely need to use an acidic rinse such as a 50% dilution of apple cider vinegar, after you’ve rinsed out the soap. This will restore the best pH to your hair and allow it to be much smoother.

Heidi says:

I wanted to first thank you for continuing to make a wonderful product!! I remember seeing this soap.in the shower in the 70’s as a young child but never used it.
Secondly I want to share with readers that I have been using the Peppermint liquid now for 2 weeks and it has improved my skin remarkably. I have several different skin issues including eczema and H.S. both of which are painful. Since using this in the shower my complexion…eczema…H.S. and cracked feet have all but almost healed!! I have been going to a dermatologist now for 35 years and have been on every internal external biologic medicine you can imagine. This is an absolute miracle for me. I will be telling my dermatologist about this wonderful soap so that others may get some relief as well. I was at the grocery store in the holistic section and came across this soap. I read the ingredients and decided what the heck. Not to mention if my parents used it …it must have been good. I chose the Peppermint because I like the smell and the cool feel of it. I have used tea tree oil to help with various issues but dislike the smell so this was the reason I went with the Peppermint.
This has been a life changer for me and want you to know how much I appreciate your product.
One question I have is do you or have you thought of making a deodorant??
Thank you

Lisa Bronner says:

Hi Heidi – Wow! Super testimonial! I’m so glad you shared it. Yes, a deodorant is definitely on our list of things to make, but I don’t have one to share with you yet. It probably won’t be this year, either, but stay tuned.

Suavemente says:

Hey I Just Bought Your Lavender Castile Soap And I Was Wondering If It Was Ok To Use It To Wash My Face And Hair? I’m Asking Becuase I Noticed You Have The Different Types Recommended For Different Uses

Thais Defalco says:

I found a recipe for creamy body wash that is basically coconut oil, shea butter, a choice of carrier oil, some vitamin e and castile soap. One has to melt all oils in a double boiler, put them in a blender, put the castille soap in the blender and blend everything together to form a thick, nicely sudsing body wash. The amounts are 1 cup castille per ~1 1/4 cup oils/butters. I love how it feels like a luxurious cleansing lotion but i have been wondering 2 things: would this dilution (soap:oils) make this wash too harsh? Would i need to dilute it further?

Lisa Bronner says:

Hi there – I don’t think this mixture would be too harsh. I use the soap just diluted with water and it’s very mild. Also using coconut oil and shea butter would make it very moisturizing. The question more is, would this mixture actually clean? There are so many oils in it that it might bind up all the cleaning power of the soap. One way to test this is to put some pure oil – coconut, let’s say – on your hands. Then use this body wash mixture to try to wash it off. Do your hands feel clean afterwards or do they still feel oily? I don’t think diluting it further with a carrier oil would help.

Lisa Bronner says:

Hi Nicole – Unfortunately, it is not. The pH of the soap is too high. Shampoos that are safe for color-treated hair have a slightly acidic pH.

E says:

Hi, I have oily/fine hair and found the dilution method works best for me so I use the castile soap as a hair rinse (followed by water rinse than diluted ACV rinse as usual) . The first time I applied directly to wet scalp (few drops/maybe a tablespoon ) but it left my hair flat and dull. Maybe my ratio of ACV was off as I have had to adjust it before when I did the baking/acv method but I will stick with what I know works. So I would encourage anyone to try the diluted method for hair if applying it like normal shampoo didn’t work for you.

I use the peppermint as that got the best rating on the Skin Deep Database (though the others were close!). The tingling is something to get used too but I like that the scent seems to stay for a while 🙂

LeAnne says:

Hi there!

I would love to use this for laundry but I have a front loader with a pull-out liquids dispenser for laundry soap, fabric softener, and bleach. How should I use the white vinegar in this case? It is a HE washer if that helps:)

Thank you so much!

Lisa Bronner says:

Hi LeAnne – The vinegar would go in the fabric softener spot.

melissa abers says:

hi lisa-
happy, healthy new year!
i have two questions:
1) can dr. bronner’s be used to clean up pet stains?
2) for an all purpose use, would you recommend your baby formula or almond formula or should i stick with the unscented?

William Brower says:

These soaps clean carpet well! For an all around use, I suggest peppermint or almond

Natasha says:

Hi there, I really like Dr Bronners Liquid soap (I use it for laundry washing), and I’d love to use it to make my own hand soap but I don’t like the idea of pre-diluting it with water and certainly not leaving it diluted for as long as 2 weeks – it’s just not safe. I make my own natural products and the moment you add water to anything, you’re creating a breeding ground for bacteria if you don’t add a preservative. Tocopherols (Vitamin E) is not a preservative. It’s an antioxidant and should only be used to extend the shelf life of oil-only products. Would you recommend using this undiluted as a hand soap at all? Thanks!

Jeffrey M. Stone says:

I live in Salt Lake City, and shop at Whole Foods, who used to carry your products. Now, they don’t, at least the store in Sugarhouse doesn’t. I don’t live close to the other WF stores, but I could call to find out if they carry your products. Since you have an easy way to communicate, I’m asking you about getting your product in SLC, if not at WF, then maybe some other place.

I like the convenience of shopping at stores when I need anything, but I’m going to order something here today, so I know I”ll have what I like for cleaning here sometime soon. Great products! They really work, and are enviro-friendly!

Marijo Young says:

The Whole foods in South Jordan across from Scheels on 11400 carries Dr. Bronners.

Robyn says:

Hi Lisa,

I just heard about Dr. Bronner’s soap and I’d like to purchase one for my 16 year old to try for her severe eczema, including what she calls her “heaeczema” on her head. I’m torn between purchasing the baby soap or the tee tree oil soap. Which would you recommend? Also, would full strength be gentle enough for her skin? She has open wounds in some spots.

Thank you!

William Brower says:

Don’t use full strength, that’s a waste of soap. Tee tree, peppermint and lavender are all good soaps for sensitivity

Lori says:

Hi…Just wanted to make a comment on using the soap on dogs. I have a little chihuahua that has occasional seizures. I used the Bonners Eucalyptus soap last year during the summer thinking it might help with the fleas. Within a half hour of the bath, he had a seizure. I don’t know for a fact that it was directly related to the soap but I have not used it on him since. Maybe if I had diluted it, it would not have caused a problem. I am afraid to try it again. So I would recommend, just for safety’s sake, if you have a pet that is prone to seizures, do not use or at least dilute if you do.

Beatriz says:

Would Castile soap do ok with well water? I love the product but currently live in home with Well water and just curious if it’d make a difference in its quality

William Brower says:

It works perfect. I just loved to a well myself

Karen says:

Dear Lisa,

I have just read here the suggestion to add a small amount of tea tree oil to liquid Dr. Bronner’s for general cleaning, and I will try that next. What I have done so far for mopping the bathroom and kitchen floors (linoleum) as well as cleaning bathroom surfaces came from adapting a suggestion on a natural cleaning blog: I’ve combined several good squirts of Dr. B’s with a couple of squirts of hydrogen peroxide, then added some very hot water (from a recently boiled kettle). This makes an excellent cleaning solution (and smells wonderful while I’m cleaning).

I do have one other question, about your recipe for washing with Sal Suds (which I’d like to try)–you mention that the recipe is for a normal top-loading washer and say to put the mixture in the fabric softener cup so that it will be added during the rinse cycle. The apt. building where I live has top-loading machines, but they don’t have any way to add something during rinse; the only machines with compartments for bleach, pre-treating, laundry soap, and (perhaps) softener are two front loaders–is it OK to use the same recipe amount for this type?

Many thanks,
Karen R

shayleene says:

I just purchased 18-in-1 Hemp Cherry Blossom Pure-Castile Soap to supplant the other the counter hand soaps. I know your stance on using regular pumps for using this for hand-washing. If I get foaming bottles, how much water and how much soap. I need measurements because I do not understand the 1:3, what does that translate to in measurements? Thanks. I recently traveled far to pick up this soap and would like to use it right away. Thanks! Shay

William Brower says:

Try Iike half an inch of soap, then fill the pump halfway with water. Try the pump and see how the foam is. It can be thinner or thicker as you desire it. Let us know!

Kayla Tilly says:

Hi
I have been battling acne lately and saw on a YouTube video that this soap helped them to clear their breakouts, which would you suggest to use as a nightly face wash for helping reduce acne?

William Brower says:

Kayla, there are three that can help, and any of them will be much better than commercial soaps. Tea tree is good for being an astringent, aka removing oils. Peppermint is very cooling, and mint is a good medicinal. Lavender is a great calming agent, to soothe the acne. Plus different peoples acnes are different. Let us know which works best for you. FYI some people get baby mild to get away from any fragrances in their skin. I would try this is the three others didn’t work, because you might have a different sensitivity than you realize

cindy clark says:

hi lisa my name is cindy … I’m trying your 18-in 1 hemp peppermint liquid castile soap. I really like it!!! my question is.. like to put this soap into any size foampump container, how much should peppermint liquid castile soap should I put into a container whether large or small. that way I do this right the first time. could you please send me the info how much soap I need to put into these different size containers and the water amount! thank you sooooo much! merry Christmas and have a wonderful new year!!! sincerely yours… cindy clark

William Brower says:

Cindy, different pumps work best with different thicknesses of soap. Try out a one to ten ratio by filling just a smidge in the bottom, then fill with water. See if the pump foams and gives you enough lather for your hands.

MrsFitz says:

I love this stuff! I buy the Peppermint/Hemp soap in a big bottle, then put a smaller one in my shower for use in the “puffs” as a great body wash. You feel “squeaky clean” when you are done & it doesn’t irritate my “lady parts”. I wash my dog with it & people comment on his “shiny coat”. I also use it on my houseplants, to spray them for bugs, before bringing them in after a summer on the deck. Bugs dislike peppermint.
Giving it for gifts this Christmas. Thanks!

William Brower says:

Squeaky is a good word for it. I describe it as feeling like the skin of a bell pepper

lynn batson says:

I can not purchase your 18-IN-1 Hemp Tea Tree Soap in our area but I can get the Hemp Almond. My husband likes the tea tree and I am wondering if you can tell me how much tea tree oil to add to the almond soap. Thank you and keep up the help site.

Summer says:

Looking to use the baby gentle Castile soap in a diaper spray solution. I’m combining with water and oil. What overall ratio should I look to use in this situation? Our bottles are about 14oz.

William Brower says:

I would try one ounce of soap, and then experiment from there. If that’s too much soap, pour some into a cup and add water.

JENNIFER BAKER says:

Can I use this product in a foaming pump as a shampoo and body wash for my children? What soap/water ratio do I use? Thank you.

William Brower says:

Most definitely, try like a one part soap to ten parts water.

Dr. Bronner is magical – CabinCrew&Beyond says:

[…] 目前只有用它來取代洗碗精,因為洗碗精常常有刺鼻味加上用久了手非常乾,感覺很傷手,就試試看這瓶,也因為他強調都用有機油。使用一陣子後覺得對每天洗東西的主婦來說也比較不傷手。不過如果依照1:10的比例我覺得有點不夠力,尤其是有很油的鍋或是盤,需要的用量會很多,所以我自己改成1:5 感覺給力多了~也不需要一次要擠壓很多稀釋液。 另外發現一個非常棒的妙用!! 幾天前我把我尢的衣服洗到染色,一件純白t跟兩件鵝黃色的polo衫被染成斑斕的藍色。非常傷心只好趕快來google有沒有人分享妙方,結果有人說可以用熱水煮肥皂絲然後把衣服泡在裡面,染劑會掉。 我就想到Dr Bronner也是一種肥皂而且是液態的還不用去煮到化開,我就隨意倒一些,配合我們家的洗衣機功能,使用熱水加pre-soak,讓衣服在洗衣機裡泡熱水最後還可以直接脫水,結果真是太令人滿意了!!! 染到的斑斕全部不見!幾乎看不出來有染過了!!!衣服都回到可以穿出門的狀態!! 是絕望家庭主婦的救星呀!!! 光是這樣我就覺得值得買一瓶放在家裡,尤其是他有那麼多用途。 我也有稀釋後拿來當作除蟲劑噴灑在我家院子跟窗邊,剛好是薄荷口味所以蟲子應該也會比較不會靠近。 他還有出很多款用途的肥皂和香味,我在costco買的一大瓶才11鎂多,不一定每次架上都有,或在trader joe’s也會出現薄荷口味,稍貴一點但也一次可以買很大瓶。 如果不想家裡充滿各種清潔劑的化學揮發跟味道,我覺得可以試試這個! 很多外國人會分享更多使用應用喔!

Dawn De Luca says:

I’d like to know if the soap would have any effect on mosquitoes, either as a repellent or kill them.

Carol swinyer says:

Hi I bathed my 10yr old lab (her first bath in years) a few weeks ago. I used dawn dish soap with cider vinegar and diluted it by half with water. I made her so miserable?. She is itching and digging her skin. I just remembered your peppermint soap and how much I loved it as a teenager. Do you think It might calm her itching down. I u ready had the vet give her a cortisone shot, which did not help.?. I’m despite..please help me.

Janet Mayeux says:

A few questions, please:

Can I safely use the liquid castile soap on granite counter tops?
Is the lavender castile soap anti-microbial?
Will it disinfect the counter top? If not, will any of the castile soaps?

My 11-year-old has some type of dermatitis all over her body. The doctor prescribed caratzone cream, which really doesn’t help, and I am (I realize you cannot give medical advice). If I wanted to try tea tree oil, how would you dilute it?

JodyW. says:

you could also try Yardley soap. or at the farmers co-op or amish market get grandmas pure and naturl lye soap. possibly allergic to all the perfums in standard soap. I know I am.

William Brower says:

This soap works great for countertops. I would try both tea tree and peppermint for your son, to see which works best for him. Use a normal size plastic water bottle, and add like half an inch of soap to the rest water. Poke a hole in the cap with a nail. This allows you to make a cheap applicator, because you waste much pouring from the bottle

Courtney Koehn says:

Hi Lisa,

Background: I’m putting together a mock business plan for my MBA program. We needed to create a socially responsible business model that meets a real need or problem. So, our business plan is to import Dr. Bronner’s to Peru, where the WHO has made some headway with handwashing initiatives using a device called the SJ, Super Jaboncin. It’s essentially two 3-liter bottles turned upside down with “sport cap” closures. One bottle has soap and the other has water. While I know the liquid castile soap isn’t recommended for traditional soap dispensers, I’m guessing that the sport cap’s ability to prevent any evaporation would keep the soap from clogging the cap.

Question: What dilution ratio for the liquid soap would you use to create a handwashing soap that will lather well enough to be effective but minimizes cost per use? Or would you recommend making a liquid soap by shaving the bar soap and mixing it with hot water? If so, what ratio?

William Brower says:

Liquid soap, and try around an inch of soap in the bottle with the rest water. Adjust more or less as desired.

Holly says:

Hello! It was mentioned to me that Dr Bronner’s is good for cleaning piercings, so I’ve done a little research and have come up empty handed. I am hoping that you could give me some advice on whether I can use Dr Bonner’s soap for cleaning piercings and if so what dilutions should I use and how can I go about doing this?
Thank you!

William Brower says:

The pump soap comes ready to use for hands and face. If you want to use it for other things, you may want to dilute it more. That all depends on the application.

Rachel Kasinger says:

Hi there. I am wanting to purchase a gallon of soap at a time, as I use it in so many instances. Is there a pump that could be attached to the bottle to ease use from such a heavy large bottle?

William Brower says:

There are pumps available. Look at one gallon pumps on Amazon.

PEGGY BARTELS says:

I have the 18-1 Hemp baby liquid pure Castile soap (Dr Brimmer’s). Heard I can do enemas with this. Doo you have the recipe for the enemas?

J Barnes says:

I use 1 to 2 tbsp for two quart enemas. Works great and is mild.

Lisa Bronner says:

Hi Peggy & J- While the soap is safe to use on all external areas, we recommend caution using it internally. If you do so, be sure to rinse very thoroughly as leftover soap can be irritating. Leftover soap could also increase the pH internally.

kristen says:

I researched potassium hydroxide and it is CORROSIVE. I thought you were supposed to be an organic company? Why is there harmful chemicals in your products??!!

Nate says:

Potassium hydroxide is in ash and has been in soap making for centuries

Laci Rae Weber says:

POTASSIUM HYDROXIDE IS USED IN FOOD~
Potassium hydroxide is often found as an additive in commercially processed foods, and as a rinse or chemical peel for fruits and vegetables. It is added to processed foods as a stabilizer to prolong shelf-life, and as a thickener. It’s involved in chocolate and cocoa processing, soft drink processing, and in the thickening of ice cream. Potassium hydroxide is used to soften olives and to glaze pretzels before baking to make them crisp.

R.Lee says:

Peaceful greetings. If one looks on the lable of a Dr. Bronner’s castile soap bottle, one might notice​ a symbol looking like “+” after the listing of “Potassium Hydroxide” among the ingredients — this symbol designates a note concerning this substance. The note reads: “None remains after saponifying oils into soap and glycerine.”. This would be a bit like adding herbs in a sachet to simmer in a soup, and then listing the sachet as an ingredient. Yes, it was in there — for the purpose of other ingredients — but it was taken out. I hope the site owner does not mind my having answered this question, and I hope I answered well enough until an official reply — it’s just that I didn’t want to see anyone deterred from such a lovely, natural, plantbased product, mistakenly thinking it is harmful. Peace.

William Brower says:

The potassium hydroxide gets used up in the soap making process. It’s an ingredient, but it’s not in the final product.

Rand says:

I couldn’t help but roll my eyes at your comment. I’ve seen lye soap made, and all its ingredients are natural.

Diane Lindstrom says:

hello Lisa–hope you can help with a few questions. My dog was diagnosed with scabies, and was treated with Apoquel, which cleared up her infestation very well! She’s back to normal colored skin, her hair is growing back and she doesn’t scratch but maybe once a day. However, because it took our vet so long to diagnose (5 weeks), my husband and I are now infected with what we believe is a form of canine scabies. We went to our own doctor, who didn’t seem too concerned…she prescribed Permethrin treatment, which we did twice, and we’ve continued to wash our clothes, towels, linens, sheets, etc. in hot water with a hot machine-dry afterwards….but we’re still getting either a) bites or b) residual effects of what scabies we may have had. I read online that Castile soap is a good natural remedy for scabies, and many people swore by it. Have you heard of this? Would you recommend using it, and in what dosage? I’m sorry to be so long-winded, but we’re tired of the itching and reoccurrence of bites and frankly, don’t know where to turn next without spending thousands of dollars on “we promise to fix your problem” remedies. thanks for any suggestions! Diane p.s. the dog continues to be scabie free!

Hi Diane,
If you find that Castile soap alone helps but doesn’t completely clear up your condition, try using some Colloidal Silver diluted half and half with water and spray this on your skin a few times a day, as well as mix some Olive leaf extract with some olive oil/Vaseline and rub this over the affected area twice a day. My daughter was diagnosed with Molluscum a few months ago, which is little infected looking sores that spread, and the Dr’s told me it was something that you just had to leave to clear up on its own and it could take anywhere from a few months to a few years. They were horrible looking sores too. I didn’t listen and used these 2 methods and it was all cleared up within a week.
You could also try some frankincense essential oil and myrrh essential oil mixed in carrier oils (olive/almond/hemp/coconut oil) as they are also great for skin conditions & healing, but they can be expensive since they are very concentrated so make sure you dilute correctly. (Only 2 drops essential oil for every 5ml of carrier oil).
Hope this helps you and your husband.

I would use peppermint or tea tree oil

Alison says:

Hi There
I notice your liquid soaps dont contain any preservatives. How do you ensure that they wont go mouldy or grow bacteria? Thanks

Laci Rae Weber says:

vitamin E is used as a preservative

Jennifer says:

the vitamin E acts as a preservative

Marla says:

Hi I just brought the citrus Castile soap . Can I use this to wash fruits and vegetables and leafy greens.

Thanks

Laci Rae Weber says:

recipe above~
Fruit and Veggie Rinse: 1 dash (approx.. ¼ tsp.) in a bowl of water. Dunk produce and swish. Then rinse in clear water.

William Brower says:

Yes, any of the soaps can be used as a fruit wash, just one dash soap into a bowl of water, then rinse afterwards

Emma J. Thompson says:

Lisa – first off, from a former social media manager, A+ job. Your replies are genuinely thoughtful, timely and helpful!

Second – I’m a brand-new user, and I also picked up some bar soap. Can I use this to wash my hands/body without any dilution?

William Brower says:

Emma, the bars can be used to wash the hands and body, as they are. Some people even buy the bars to break down into a liquid, but I just get the concentrate.

Miriam says:

So i’m new at this soap, and I’m trying to figure out between unscented baby-mild pure castile soap that would need to be diluted 1:3 and put in a foaming dispenser. Or to use the Baby Unscented Organic Pump Soap? I def need something unscented. I’m trying to figure out the difference between these 2. Also, does 1 have a longer shelf life than the other? Does one clog up eventually? What are the pros and cons?
Thanks so much!

I have been using Dr. Bronners Castile Hemp Almond soap for over 8 years now. There is a foam dispenser by my kitchen sink, one by by bathroom sink, and one in the shower. I mix it up with distilled water in the dispenser and have NEVER had the trouble commenters below are talking about. I use a bottle, 8.75 oz., 7oz. water with 2 capfuls of Dr. Bronners and use it for handwashing, shampoo, and showers. Do I measure exact everytime? Nope. But it works just fine.
I also use Dr. Bronners Sal Suds for handwashing dishes, mopping the kitchen and bathroom floors, cleaning all surfaces in both rooms except the bathroom mirror (just plain distilled water and vinegar for that).
Appreciate the easy rinse factor with all Dr. Bronners products.
