Functions

Emulsifying

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

Skin Conditioning

A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

Emollient

Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.

Emulsifier

Mixes Oil & Water

Traditional Use

A synthetic derivative combining polyethylene glycol with castor oil, traditionally used in folk and Ayurvedic medicine for skin conditioning. The modified version was developed in the 20th century to improve water solubility in cosmetic formulations.
