Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks in moisture
Traditional Use
A modern emulsified derivative of marula oil created through synthetic esterification. Marula oil itself has been traditionally used in southern African skincare and haircare for moisture and nourishment, though this specific polyethylene glycol ester is a contemporary formulation ingredient.
