Common Name(s): Propylheptyl caprylate,propylheptyl caprylate,cosmetic functional ingredient,established active

CAS Number: N/a

DESCRIPTION

What It Does: Provides emollient conditioning with spreading value determined by the ester molecular architecture.

Why It's Used: Propylheptyl caprylate is selected for its c8 caprylic ester — the c-chain length provides ultra-light fast-dry short-chain emolliency, which distinguishes propylheptyl caprylate from esters of adjacent chain lengths in the same polarity tier.

How It Works: Ester: acid chain → emolliency type; alcohol chain → spreading speed and skin feel.
