Common Name(s): Ppg-3 hydrogenated castor oil,ppg-3 hydrogenated castor oil,botanical oil/butter,emollient efa source

CAS Number: N/a

DESCRIPTION

What It Does: Provides emollient conditioning from sc-compatible fatty acid triglycerides — oleic, linoleic, and linolenic acids supporting barrier lipid supplementation and ceramide precursor delivery.

Why It's Used: Ppg-3 hydrogenated castor oil is selected for its ppg-3 propylene glycol chain — the 3-repeat methyl-substituted ether backbone provides short-chain co-solvent and humectant with limited lipophilicity, distinguishing it from both unsubstituted peg (fully hydrophilic) and organic glycols (no lipophilic tail).

How It Works: Fatty acid triglycerides integrate into sc: oleic (c18:1) provides fluid emolliency; linoleic (c18:2) serves as ceramide precursor; alpha-linolenic (c18:3) provides anti-inflammatory benefit.
