DESCRIPTION
What It Does: Provides emollient conditioning from sc-compatible fatty acid triglycerides โ oleic, linoleic, and linolenic acids supporting barrier lipid supplementation and ceramide precursor delivery.
Why It's Used: Ppg-8 sorbitol castor oil is selected for its ppg-8 propylene glycol chain โ the 8-repeat methyl-substituted ether backbone provides mid-range amphiphile balancing water miscibility and lipophilic penetration enhancement, 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.
