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.
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.
