Common Name(s): Dimethiconol meadowfoamate,dimethiconol meadowfoam seed oil (limnanthes alba) ester,silicone-meadowfoam seed oil (limnanthes alba) hybrid emollient
DESCRIPTION
What It Does: Provides a light, silky skin feel combined with the conditioning benefits of meadowfoam seed oil (limnanthes alba).
Why It's Used: Combines the non-greasy, quick-absorbing feel of silicone with the nourishing fatty acids of meadowfoam seed oil (limnanthes alba); ideal for luxury lightweight formulas.
How It Works: Ester bond links dimethiconol (silicone) with c20:1 eicosenoic acid (dominant meadowfoam fatty acid) fatty acids from meadowfoam seed oil (limnanthes alba); the silicone backbone provides low surface tension and smooth glide; the meadowfoam seed oil (limnanthes alba) ester tail provides substantive conditioning.
