Common Name(s): Dimethiconol stearate,dimethiconol stearic acid from plant ester,silicone-stearic acid from plant hybrid emollient
DESCRIPTION
What It Does: Provides a light, silky skin feel combined with the conditioning benefits of stearic acid from plant.
Why It's Used: Combines the non-greasy, quick-absorbing feel of silicone with the nourishing fatty acids of stearic acid from plant; ideal for luxury lightweight formulas.
How It Works: Ester bond links dimethiconol (silicone) with stearic acid (c18 saturated) fatty acids from stearic acid from plant; the silicone backbone provides low surface tension and smooth glide; the stearic acid from plant ester tail provides substantive conditioning.
