Castile Soap DIY’s










Ingredients: Saponified Organic Cocos Nucifera (Coconut Oil), Saponified Organic Otea Europaea (Olive Oil), Saponified Organic Simmondsia Chinensis (Jojoba Oil), Rosemary Extract, Organic Aloe Vera.


Now that Plant Therapy has added Castile Soap to our line of products, I went in search of different ways to use it. To my surprise, there are hundreds of uses for it! While I am testing out and tweaking these recipes I thought I would share a few of my favorites.


Foaming Hand Soap

What you’ll need:

What you’ll do:

  1. Add the water to the foaming pump dispenser
  2. Add Castile Soap, Optiphen +, and essential oil
  3. Replace cap, shake well


Multi-Purpose Spray

What you’ll need:

  • 5 ounces water
  • 3 ounces white vinegar
  • 1 1/2 teaspoons Castile Soap
  • 1/2 teaspoon Polysorbate 20
  • 25-30 drops essential oil (I use Germ Destroyer or Germ Fighter in most batches )
  • Spray Bottle

What you’ll do:

  1.  Add all ingredients to the spray bottle and shake well.
  2. Spray and wipe.


Body Wash

What you’ll need:

What you’ll do:

  1. Measure all ingredients.
  2. Pour into the bottle.
  3. Shake well.
  4. Store in your bathroom and use as you would a traditional body wash.


Fruit and Veggie Wash

What you’ll need:

What you’ll do:

  1. Soak produce for 20-30 seconds, then rinse.
  2. Drain or pat dry.
  3. Storing in the fridge is needed.

KidSafe Shampoo

What you’ll need:

What you’ll do:

  1. Measure ingredients.
  2. Pour into the bottle.
  3. Shake well.
  4. Store in your bathroom and use as you would a traditional body wash.


Bubbling Bath Salts

What you’ll need:

What you’ll do:

  1. Pour Epsom salt into medium bowl and set aside
  2. Measure 1 tbsp coconut oil, into small dish or beaker, set aside
  3. Measure 2 mL essential oil with graduated cylinder {or drop 40-45 drops}. Pour into coconut oil

  5. Add carrier/essential oils mixture to the body wash, stirring well. The mixture will turn opaque and thicken slightly as you stir
  6. Add carrier/essential oil/body wash mixture to Epsom salt
  7. Stir well
  8. Package in a container of your choice, but do be sure it’s airtight!

To use, run about 1/4 cup under your warm water as you fill the tub. This is the perfect way to send yourself or your little one, or yourself, off to bed all calm and snuggly!

  • Is it ok to use plastic bottle with the DIY shampoo? Arent you suppose to use glass with essential oils? Or will it be ok?

    1. You can use plastic with your essential oil DIYs as long as it’s PET plastic. Glass is always a great option too.

  • Can you add Polysorbate 20 to the foaming hand soap recipe so that you do not have to shake it every time?

    1. Emmah, if it appears that everything is mixed and there are no visible signs of separation, I wouldn’t worry about shaking it every time 🙂

    1. Logan, try an ounce of Castile Soap with 9 drops of Lemon Essential Oil. Keep that blend separate and mix with water as needed 🙂

  • Your body wash recipe looks very good, love making Body and hand washes with Castile and am not super happy with my present well know brand, just might have to give yours a try !

    1. Since water is not added to that recipe, no preservative is needed. My confusion lies with the final instruction, “use as you would a traditional body wash.” It makes me wonder whether this is actually a shampoo recipe. Castile soap is alkaline so it’s not great for long hair especially, unless followed up with some type of diluted vinegar rinse to balance the pH.

  • can we use other carrier oils for the body wash. is it a must to use hemp seed oil? will fco b ok? any specific reason for choosing hemp seed oils over the other oils?

  • Hi there, thanks for the post! I have some questions.
    1) I would assume the body wash and shampoo can be used for both kids and shampoo?
    2) any specific reason why only the foaming handwash needs the optiphen plus, while the other DIY do not require?

  • I just made my first natural shampoo. The recipe with castile soap. I didn’t add any EO due to it already has lavender in it so we will see how it goes.

  • Oh my goodness, I love this body wash recipe. I bought glycerin for the first time to use in a diy and agree completely that it made my skin so much softer than just using castile soap alone. This smells really yummy with the sensual synergy!

  • I’m looking for a body wash recipe to put in a foaming pump bottle. Would your recipe for body wash work in a foaming dispenser?

  • A question about PH of castile soap, it is alkaline whereas our skin need PH 5 to PH5.5 foe cleansing. I am torn between this and castile soap.

  • HI! for the Body Wash recipe, is it necessary to add the vegetable glycerin and carrier oil or is this a preference? I found a recipe on the Aromahead Institute’s website that just uses castille soap and EO’s and another with aloe vera gel and EO’s. Just curious if there is added benefit to those added ingredients in your recipe:)

    1. Rachael, you can omit the vegetable glycerin, and the carrier oil, although both products offer great skin benefits. I chose this recipe because of all the others I have tried, this is the one I love the most. It’s cleansing, moisturizing, and makes my skin feel amazing.

  • Though many diy recipes call for both vinegar and castile soap, it’s really not a good idea to mix them together. It’s not dangerous or anything, but the vinegar (or any acid, like lemon juice) will basically un-saponify the soap, making an oily, curdled mess. If you’re mixing small amounts with water, you might not see the reaction, but you’re still losing the cleaning power of the soap! (Mix a small amount of soap and vinegar, undiluted, in a dish, and you’ll clearly see the problem!)

    Castile soap on it’s own simply diluted with water, with your EOs of choice, makes a great surface cleaner. If you get residue (on certain surfaces or because of hard water), follow up with a SEPARATE vinegar (also dilute) rinse!

    1. Zd, thank you for your feedback. We have tested this recipe and if you use the Polysorbate 20 this does not happen. When I tested it out it worked perfectly and is still good after several weeks.

      1. Cool! Thanks so much for the reply… I’ve seen tons of similar recipes shared online, but none of them include this ingredient. Did some quick searching to get an idea of the chemistry going on… so basically the Polysorbate 20 acts as a solublilizer, which helps ingredients to mix together that otherwise wouldn’t be able to? I’ll definitely have to give this try!

    1. Angela, climate can have something to do with it. I would add more of the Castile Soap until you get the right consistency. It should be moist, but not clumpy or runny.
