Functions
Anticaking
Antifoaming
Bulking
Emulsion Stabilising
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Viscosity Controlling
Locks In Moisture
Traditional Use
A modern surface-treated silica developed in the late 20th century for cosmetics to improve texture and provide a mattifying effect without the tackiness of untreated silica.
