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.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Locks In Moisture
Traditional Use
A modern hybrid silicone-polyether polymer developed for advanced cosmetic formulations in the 1990s-2000s. Functions as an emulsifier and viscosity modifier in premium skincare and color cosmetics.
