Isoceteth-20
Also known as: Isosteareth-20 · Ceteth-20
EmulsifierSolubiliser
“A solubiliser that keeps oily actives dissolved in water.”
What it does
Isoceteth-20 dissolves small amounts of oil-soluble ingredients into water-based formulas, which is why it turns up in lightweight serums that still contain oily actives. It does nothing to skin on its own.
Benefits
- Keeps oil-soluble actives evenly dissolved
- Allows lightweight, non-greasy serum textures
