Functions
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
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.
Emulsifier
Mixes Oil & Water
Traditional Use
A synthetic emulsifier developed in recent decades combining polyglycerin with macadamia nut oil fatty acids. Designed to replicate the skin-conditioning benefits of macadamia oil while providing stable emulsification in cosmetic products.
