Common Name(s): Zinc isomerized linoleate hydroxide,zinc isomerized linoleate hydroxide,cosmetic functional ingredient,established cosmetic active
CAS Number: N/a
DESCRIPTION
What It Does: Provides emollient skin conditioning with specific spreading value determined by the acid-alcohol ester components.
Why It's Used: Zinc isomerized linoleate hydroxide is selected for its c18:1 oleic ester — the c-chain length provides fluid unsaturated emolliency that penetrates sc most rapidly, which distinguishes zinc isomerized linoleate hydroxide from esters of adjacent chain lengths in the same polarity tier.
How It Works: Ester polarity controls spreading: branched short chains (logp 5-7) fast dry feel; medium chains moderate spreading; long chains occlusive. ester c=o provides polar adhesion to skin.
