Functions
Antifoaming
Hair 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.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks In Moisture
Traditional Use
A silicone polymer developed in the mid-20th century as an advanced version of dimethicone. Designed to provide superior lubricity, water resistance, and skin feel compared to earlier silicone formulations.
