Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks In Moisture
Traditional Use
Castor oil (used in Ayurvedic medicine for centuries) chemically modified through PEGylation and hydrogenation in the 20th century. Developed to create a water-soluble, more stable form of the natural oil for cosmetic use.
