Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Solvent
Dissolves other ingredients so they distribute evenly in the formula. Often the invisible "base" everything else is mixed into.

Traditional Use
Polyethylene glycol (PEG) polymers were first synthesized in the 1950s and adopted by the cosmetics industry as humectants and solubilizers to improve texture, stability, and water-binding properties in skincare and haircare formulations.
