Functions
Deodorant
Emulsion Stabilising
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Viscosity Controlling
Locks in moisture
Traditional Use
A crosslinked silicone-polyether polymer developed for cosmetics. Used to create stable emulsions and improve the texture and feel of contemporary skincare and color cosmetic products.
