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.

Viscosity Controlling

Emulsifier

Mixes Oil & Water

Traditional Use

Developed in the late 20th century as a silicone-based hybrid polymer combining polyethylene glycol, polypropylene glycol, and dimethicone. Created to improve the feel and spreadability of cosmetic formulations while providing water and silicone solubility.
