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

Locks In Moisture

Wound Healing

Antioxidant Protection

Mixes Oil & Water

Traditional Use

Synthetic PEG-based emulsifier developed in the 1950s-60s for cosmetics. Designed to provide stable oil-water emulsification without the irritation of traditional soap-based systems.
