Functions
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Traditional Use
A low-molecular-weight synthetic glycerin ethoxylate developed in the mid-20th century. Used as a humectant and emulsifier in cosmetics without traditional medicinal applications.
