Effects on biodiesel glycerin soaps:
- Castor oil will NOT participate in glycerin negation when used in biodiesel glycerin soaps.
- Bar Soap - Castor oil will add lathering properties but can reduce hardness.
- Liquid Soap - Biodiesel glycerin liquid soap will benefit from added lather with the use of castor oil.
- Hybrid Soap - Castor oil can add lathering properties to biodiesel soaps that use both sodium and potassium based glycerin.
