Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Locks In Moisture
Traditional Use
Developed in the mid-to-late 20th century as a silicone-based conditioning agent combining dimethiconol (a silicone polymer) with stearic acid. Created to provide emolliency and conditioning properties in cosmetics without the heaviness of traditional waxes.
