Functions
Binding
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.
Locks In Moisture
Traditional Use
Polyethylene glycol (PEG) was first synthesized in the 1950s and subsequently developed with varying molecular weights. PEG-150 is used as a humectant and solvent in modern cosmetics to improve moisture retention and product texture.
