Add in small quantities to increase the soap lather. Too much Castor can make your soap soft and sticky.
Castor Oil ricinus communis Latin
Derived from the castor bean
Obtained by cold pressure
Rich in fatty acids, it acts as a humectant, attracting moisture to the skin.
In soapmaking, although castor oil would appear to require less sodium hydroxide, it sometimes requires more due to its high ricinoleic acid content.
It is also a well-known superfatting agent and well suited for shampoo bars and skin-care products.
Without other oils, it produces a transparent soft soap. In combination with other vegetable oils, however, it makes a wonderfully emollient, hard bar of soap.
