    Where do I get it?

  2. Gillian says:

    Sorry, when you mention that something is an “all natural chemical-free soap,” you’ve just lost all credibility as a medical doctor. BTW, I am a professional soap-maker.

    • brenda says:

      Do you have a recipe for homemade castile soap.?

    • riham says:

      Of course it can be chemical free. I don’t know what you mean by chemicals here but if you mean the lye or sodium hydroxide then it really is not counted toward the ingredients as it is used up in the process “saponification of the oil”and it has been traditionally used for hundreds of years “from aches of wood”. It is just better now because we can make sodium hydroxide in a pure form which makes soap production more predictable!

    • Thar says:

      Sounds like you have a dog in the fight. ;)

    • sylvie says:

      actually it is chemical free- you can google the ingredients and process to understand. so don’t throw fits and make dramatic statements as you actually don’t know. cheers

  3. Greta SGT says:

    So, I love your recipes, just, one little thing. Re: Laundry Soap. Pretty sure you’d get 32 loads if you’re using 1/4 cup out of a 1 gallon batch.

    • Diana says:

      Greta SGT…He was correct in saying you would get 64 loads out of a 1 gallon batch, by using 1/4 cup per load. 2 ways to calculate: 1) 1 gallon = 16 cups. There are four, 1/4 cups per cup, so 16 x 4 = 64 uses…OR…2) 1 cup = 8 ounces, so 1/4 cup = 2 ounces. A gallon = 128 ounces. 128/2 = 64 uses.

      • kelly says:

        ***Warning- if you use for laundry, just know the Castile soap leaves a very small film on your clothes. Eventually you will need to strip it off with a astringent type of laundry soap (homemade of store bought). Truthfully…most of us who make all of our own personal and home products do not recommend Castile soap for laundry.

  4. Beatrice says:

    I love castle soap, it’s the best!

  5. Anne Belley says:

    Castile for dish soap…we get such a film on the glasses when we use it. Any suggestions?

    • Gudrun says:

      vinegar? might do the trick – i use it when i do use the dish washer as the rinse agent; I have not tried castile for dish soap as such, but will try down the road, so thanks for the warning!

    • Lynda says:

      We have the same result. We have hard water, and after reading this problem on many websites, the hard water seems to be the culprit.

      Also, never mix castile soap with vinegar (at least for those of us with hard water). It becomes a terrible mess.

      Hope this helps.

    • Bobbie Branson says:

      Yes, white vinegar will help for the residues and if you put some in your last rinse of laundry, it rinses out chemicals. My mother used it all the time for her laundry and they came out soft, with no vinegar smell.

  6. Linda says:

    Where can you buy it from?

    • Gudrun says:

      my daughter found it at TJMax already! I order mine online (vitacost.com) but there are other online stores that sell it (lower cost than amazon)

    • SUEZ says:


    • Dan says:

      You can get Kirk’s Coco Castile (bar) soap at the big box grocery stores. I’ve been using it for 45 years or more for bath and shampoo because it ALL rinses off which feels really good. It also lathers in hard water. I like DrBronner’s but Kirk’s costs less than half as much.

  7. Texas says:

    You can use about 1/2 tsp. of citric acid in your dishwasher for the film on your glasses.

  8. Reb says:

    I don’t like Dr Bonners because help oil is used to make it and I want my home to be CBD and THC free so I found Dr Jacobs olive oil Castile soap. I’m sure there are others as well.

  9. Marilyn says:

    I agree with Anne Belley. I also get a film on my glasses. If we’re hand washing the dishes, how can we avoid this?

  10. Stella says:

    I just made the liquid Castile Laundry Soap. My first wash is in the dryer. I have made a powder laundry soap for three years. I will try his dry recipe.
    Thank you for your recipes I use a lot of them and they help.

  11. Adriana says:

    A true Castile soap is 100% olive oil. Therefore 90% of soap claiming to be Castile is just really a liquid soap. This includes dr b’s!!

  12. Kelly says:

    Castile soap is not a good choice for your skin. It is very alkaline about 9-10 Ph. Your skin is more acid 4-6 Ph. Many people use Apple Cider Vinegar to try to bring the skin back to a Ph that is closer to normal after using Castile soap. But…Why would you agitate your skin in the first place and take it up to a very unacceptable alkaline Ph to begin with. Then dump an acid on it to try to normalize it back to a natural acid Ph. Up and down. Ummm…NO. Using a correct Ph soap on your skin is critical to healthy skin. And FYI..the same goes for using Castile soap on your scalp/hair for shampoo. Unfortunately, shampoo is one of the hardest homemade products to make without some sort of undesired outcome. I use Morrocco Method. Its perfect! You only use a small amount and don’t need conditioner. I know what your thinking…What?? No conditioner?? I thought the same thing till I tried it. I bought the 5 elements (5 different kinds). I did not know how important it is to rotate your shampoo’s. You can use it for body wash, however I don’t prefer it.

    • Anita says:

      So, should we use Castile soap at all?

      • kelly says:

        Anita, the longer I make my own products, the more I do not like Castile soap. In fact I have 4 hugh bottles that I know I won’t use. I don’t like the film it leaves. The only time I use it is when making my own cleaning wipes for kitchen and bath. Im so cheap, that I won’t get rid of it. The key to using Castile soap is to use only an itty bitty amount (table spoon or so), mixed with Tea Tree Oil (10-15 drops to eliminate mold and bacteria) in 3 cups of Distilled water (ONLY use distilled water, its clean and has NO bacteria, fungus or chlorine) I cut Brawney or Bounty, full size paper towel roll, in half with a bread knife. Whisk your 3 cup solution and quickly dump appox 1 cup into your empty dispenser, put your 1/2 cut paper towel in, whisk remainder of solution again and quickly pour the remainder on your paper towels in making sure to wet the cardboard in the middle of the paper towel (or you can wet your cardboard tube prior). Pull the cardboard in the middle of your paper towels out, thread the your container lid and voila, you have clean, carcinogen free wipes. I make my own baby/personal wipes using Almond Oil and a few drops of Tea Tree Oil. The best wipe dispenser I have found is at Aromatools.com. It is one hand operation with a lid, Keeps your wipes moist/wet. Omni-wipe container #9833. Its on sale, at least for today. Have fun with your home made products. Add Essential Oils that you love. You will save a ton of money and know exactly what the ingredients are.

    • Lauren says:

      My skin has been terribly dry since using Dr Bronner’s as my daily soap in the shower. What would be a better alternative? I use Young Living body wash from time to time and get great results but it is so much more expensive than Dr Bronner’sz

      • Svetlana says:

        I use Dr. Bronner’s as face wash. Then apply small amount of coconut oil to skin. It acts as a moisturizer, plus has antibacterial properties. My skin looks so much clearer, by the way.

      • Svetlana says:

        I also dilute Dr. Bronner’s castile liquid soap, for both as face and body wash. Usually 1 drop of soap to 3 drops of water. If you feel a burning sensation to skin, then dilute it to 5 drops of water.

      • kelly says:

        Yes it is going to extremely dry all of you body/hair/scalp because Castile soap is VERY alkaline (9-10 Ph). Your skin, hair and scalp are acid (4-6 Ph). Castile should never be used on the body. Now, some people mix ingredients in to make it closer to the correct skin Ph. You will need to research to find other ingredients to lower the Ph of Castile. I have been making my own products for many years. Wont EVER put Castile soap on my body.
        If you want to buy pre made body wash it will be difficult to find one with perfect ingredients. Alaffia makes a pretty good soap with one ingredient that is iffy to me. Im super picky that is why I make my own products. It is Cocamidopropyl Betine. It is not a complete deal breaker, but…I prefer to have zero carcinogen/chemicals. I buy it at AllStarHealth.com. Cheapest anywhere for most of their products. They have a flat ship fee of $5.95. On my last order I saved $82. Make a list and then order. Free shipping is NOT free, the products are usually more.
        As for Ph body/hair wash…you are going to need to do some research to find what you like. I like to use dried herbs, flowers etc. They need to sit for a period of time to mix in Distilled water. You can add other ingredients once you have done your research to see what you are attracted to. I use Morrocco Method shampoo, it is Ph perfect. You could use that as a body wash. I would dilute it with your herb water and Distilled water. Shake before use. Your good to go.
        My all time favorite is homemade bar soap. Make a whole lot of it at one time. I do occasionally buy Nubian Heritage Raw Shea Butter Bar soap. Pick your scent. Cheapest is at AllStarHealth.com. All of these bars are large, 5oz and they are ALL the same price (unlike other sites). No undesired ingredients.

  13. LaDeane says:

    I have made my own hand soap for many years. Every recipe for soap includes the oils or fats, then for saponification you need a base. Sodium chloride is a “soda”. When they are combined they become a salt, Dr. Axe, do you have a recipe for making soap using bicarobinate of soda? I wouldn’t want to waste the olive oil just to try it.

  14. LaDeane says:

    Oops. I meant to sodium hydroxide, not sodium chloride. That’s right. Lye.

  15. Holly says:

    I cannot have coconut products so is there an economical Castile soap option without coconut?

  16. Bev says:

    Whole Foods has it, as do most local health or natural food stores.

  17. John says:

    You can also make liquid castile soap pretty easily with water, coconut oil, lye, and essential oils.

  18. Laura says:

    My home and body are totally Bronner-ized :) I do not do well with scents even some essential oils so I use the fragrance free Baby Bronner Castille liquid….. I have found that a much higher combination of water to liquid soap make for a much sudsier shampoo – my mix is only two capfuls per cup of water. An apple cider vinegar rinse make my hair soft and shiny (1/3 vin to 2/3 water). I also use it on my dogs when they get need a good washing :) Great for health and wallet!

  19. Catherine says:

    OK, let me point out that EVERYTHING IS MADE OF CHEMICALS! One atom of water is a chemical comprised of 2 hydrogen atoms and 1 oxygen atom a/k/a H2O (sorry no subscript here). Sodium, whose chemical designation is Na and which is actually a metal, combined in a 1:1 ratio with Chloride (Cl) creates table salt (NaCl).

    The real question is not “does it contain chemicals?” (of course it does, no matter what it is!) but “are the chemicals harmful?” Even water is harmful if you drink too much of it. It is uncommon but it has happened. Too much water interferes with your electrolyte balance, diluting the sodium levels resulting in hyponatremia (just Google it!).

  20. Laura Mae says:

    I make all natural soaps and sell them at a local Farmer’s Market. Saturday two little girls and their mother stood before my table checking out my soap when suddenly vocal sparks flew between the two daughters. The mother rather calmly says, “Relax. You’ll live longer.”

  21. monica stoneburg says:

    I hand wash my laundry. When using castille soap can i use the leftover soapy water on my plants seeing as the soap is plant based already?
