Functions
Hair 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.
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 hybrid modern ingredient combining propylene glycol polymer, butyl ether, and silicone (dimethicone) developed in the late 20th century. It was engineered to provide multifunctional benefits including conditioning, smoothing, and enhanced sensory properties in contemporary cosmetic formulations.
