CAS Number: N/a

DESCRIPTION

What It Does: Provides emollient conditioning from sc-compatible fatty acid triglycerides supporting barrier lipid supplementation and ceramide precursor delivery.

Why It's Used: Fish liver oil is selected for the distinctive triglyceride fatty acid profile of fish liver — the specific oleic, linoleic, and saturated fatty acid ratio determines the spreading speed, occlusion level, and sc barrier integration properties unique to this botanical oil.

How It Works: Fatty acid triglycerides integrate into sc: oleic (c18:1) provides fluid emolliency; linoleic (c18:2) serves as ceramide precursor; gamma-linolenic (c18:3 n-6) provides anti-inflammatory benefit.
