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 modern polyethylene glycol-modified derivative of camellia (tsubaki) oil glycerides developed in late 20th century cosmetics. Created to incorporate the traditional Japanese skincare benefits of camellia oil into more stable, water-soluble formulations.
