Functions

Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.

Surfactant Cleansing

Surfactant Emulsifying

Traditional Use

Synthetic emulsifier made by PEG modification of castor oil, used for centuries in traditional Indian Ayurvedic medicine and Egyptian skincare. Created to allow castor oil's emollient and anti-inflammatory properties to function in water-based products.
