In this soap making video, I share 3 ways to use oats in handmade soap; including oat milk, oat oil and colloidal oatmeal. I also show you how I use these ingredients to make a triple oat soap with the hot process method. Thank you for watching!
Please wear proper safety equipment when making soap.
Triple oat soap recipe:
Recipe calculated with: soapee.com/calculator
Oils:
25 g oat oil (5%)
175 g olive oil (35%)
150 g coconut oil (30%)
100 g shea butter (20%)
50 g cocoa butter (10%)
Frozen oat milk:
for the hot process version: 176 g
for the cold process version: 120-140 g
10 g citric acid + a splash of distilled water
Sodium hydroxide lye:
when adding citric acid: 76.5 g
without citric acid: 70.5 g
2 tsp colloidal oatmeal
10 ml fragrance or essential oil for a light scent (I used ‘honeywash’ by gracefruit)
Cure the soap for about 4 weeks before using on your skin.
○ Citric acid information
When citric acid and sodium hydroxide lye (NaOH) are combined, sodium citrate is created. Sodium citrate works as a chelator in soap.
A chelator traps metal ions such as calcium and magnesium that can be found in tap water.
These metal contaminants can cause rancidity and soap scum in handmade soap.
A chelator binds to these metals so that they can’t bind to the soap molecules. This way the soap won’t react with them and the soap's lather improves + shelf life increases.
Citric acid does not lower the pH of soap. Instead it consumes some of the lye and increases the superfat. Add 6 g extra lye for every 10 g of citric acid added to a soap recipe if you want to keep the superfat % at the same level.
How much citric acid should be added to soap?
Usage rate in bar soap is 1-2% of the oil weight.
How to use citric acid
Add citric acid to the distilled water and dissolve completely before adding the lye, or make a separate solution of citric acid and distilled water and add to the oils.
