PEG-8Hydrator
A water-soluble polymer used as a humectant and solvent that keeps formulas smooth.
What it does
PEG-8 is a short polyethylene glycol that mixes readily with water. It holds water at the skin surface, dissolves other ingredients, and gives a formula a smooth feel. It is a humectant-and-solvent ingredient rather than a skin active.
