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.

Humectant

A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.

Solubilising

Locks in moisture

Traditional Use

Developed in the late 20th century as a synthetic solubilizing agent derived from cyclodextrin technology. Used in cosmetics to improve the bioavailability and stability of poorly soluble active ingredients.
