Common Name(s): Butter decyl esters,botanical oil/butter,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides emollient conditioning, essential fatty acid (linoleic, linolenic, oleic) delivery for sc lipid barrier repair and tewl reduction.
Why It's Used: Natural carrier oils provide sc-compatible lipid composition for genuine barrier bilayer integration โ different from surface-occlusive mineral oil.
How It Works: Triglyceride fatty acids integrate into sc lipid bilayers โ oleic acid (c18:1) provides fluid emolliency; linoleic (c18:2, omega-6) serves as essential ceramide precursor; saturated fatty acids (c16, c18) provide occlusive barrier reinforcement. efa composition determines sc compatibility and barrier repair efficacy.
