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
Synthesized from polyglycerin and myristic acid in the late 20th century. Designed to provide stable emulsions in cosmetics with balanced hydrophilic-lipophilic properties for diverse product types.
