Common Name(s): Brassica napus seed oil,brassica napus seed oil,botanical oil,emollient efa source

CAS Number: N/a

DESCRIPTION

What It Does: Provides emollient conditioning from sc-compatible fatty acid triglycerides with the specific oleic, linoleic, and saturated fatty acid ratio of brassica napus determining barrier repair properties.

Why It's Used: Brassica napus seed oil is selected for the distinctive lipid profile of brassica napus — the specific efa composition determines spreading speed, occlusion level, and sc barrier integration properties unique to this botanical source.

How It Works: Botanical oil triglycerides: oleic c18:1 → fluid emolliency; linoleic c18:2 → ceramide precursor; sfa → structure and occlusion; sc lipid bilayer integration.

Typically Found In: Skin care,barrier repair
