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.
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
A specific silicone polymer formulation developed in the cosmetics industry for lightweight, non-occlusive conditioning and water-resistance in modern skincare and makeup products.
