Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

Traditional Use
Castor oil has been used in traditional medicine across Egypt, India, and the Middle East for centuries as a skin conditioning and healing agent. Hydrogenation was developed in the early 20th century to create a more stable, solid form suitable for cosmetic formulations.
