Gentle Body Wash Recipe
Makes one 8 oz. bottle
This gentle body wash recipe uses a castile (olive oil) soap base, which is a mild, light lathering soap, renowned for its gentle cleansing and moisturizing properties.
If you've already pre-made some castile soap paste, skip to Part 2. Alternatively, you can start with our pure castile liquid soap, and skip to Part 3.
Part 1: Make a castile soap paste
Ingredients:
| Olive Oil | 1400 grams | 49 ounces | | Potassium Hydroxide | 280 grams | 10 ounces | | Soft or Distilled Water | 850 grams | 30 ounces |
|
|
| | Total actives (excluding water) | 1680 grams | 59 ounces |
Instructions:
When making your liquid soap recipe, pay special attention to:
- Adequate mixing of the soap oils and potassium hydroxide
- Cooking of the soap mixture for sufficient time after trace
1. Prepare utensils, double boiler, and mixing tools.
2. Measure out and begin heating oils to 160 degrees.
3. Measure out potassium hydroxide.
4. Measure out soft or purified water.
5.
Slowly add potassium hydroxide to water to create base solution. This
solution will be approximately 150 degrees after mixing. Allow to cool
to 140 degrees.
6.
Remove oils from heat or turn off burner. In a slow and steady stream,
add the base solution to the 160 degree oils, stirring constantly with a
whisk.
7. Continue stirring constantly
(we recommend using a regular kitchen stick blender) until the soap
mixture is quite thick and has the consistency of salt water taffy. The
higher the coconut oil content, the stickier the mixture will be.
Maintain a temperature of 160-170 degrees during the mixing process.
Mixing time can range from as little as 5-10 minutes for a coconut oil soap, to two hours for a castile liquid soap.
Mixing
time can be shortened by using existing soap base as a starter. Use 3
to 4 ounces of soap base per batch. Add to the oil/base mixture and
fully mix and dissolve it in.
8.
When the soap has thickened and has the consistency of taffy, place the
soap pot in the double boiler and "cook" the mixture in gently boiling
water. After 5 to 10 minutes of cooking, check for separation by
stirring the mixture and looking for a watery liquid on the bottom of
the pot. Stir well and continue cooking for another 10 minutes. Check
again for separation and stir well.
9.
Continue cooking the mixture for a minimum three hour period. During
this time, you will note that the mixture will become translucent. After
three hours turn off the heat and let the paste stand in the double
boiler overnight if possible.
10.
After a three hour cooking period, you can test your soap mixture by
dissolving 30 grams (one ounce) of the soap paste into 60 grams (two
ounces) of soft or distilled water. When the sample is cooled it should
remain clear. If your cooled sample has a milky appearance, it means
that it still contains free fatty acids, in which case, you'll need to
return the mixture to heat and resume cooking for 30 to 60 minutes. Test
again, and repeat as required until your cooled sample is clear.
11.
The completed soap paste can be used immediately or can be stored in a
sealed plastic bag for an extended period of time, to be used as and
when required.
Part 2: Dilute your castile paste
Dilute
your castile soap paste to 20% actives, using 3 parts water to 1 part
paste. For the recipe below, use 187.5 grams of water to 62.5 grams of
castile paste.
1. Crumble the paste into hot water, stirring gently with a spoon or whisk until all of the paste is fully dissolved.
Part 3: Customize your castile liquid soap
This is the part where you turn your liquid castile soap into a lovely gentle body wash!
1. In a bowl, measure out:
2. Add and stir gently to combine:
3. Add and stir gently to combine:
4. Stir in fragrance oil or colour (Optional)
5. Mix together gently in a measuring cup until fully combined.
6. Pour into bottles.
