Common Name(s): Octyldodecyl erucate,octyldodecyl erucate,octyldodecyl ester,branched c20 alcohol emollient
CAS Number: N/a
DESCRIPTION
What It Does: Provides very-long-chain unsaturated emolliency with unique spreading slip with the branched c20 octyldodecyl alcohol skeleton โ the non-linear chain geometry creating low skin drag and non-greasy finish that distinguishes octyldodecyl esters from all linear-chain equivalents.
Why It's Used: Octyldodecyl erucate is selected for the octyldodecyl ester's luxury-texture benchmark โ the 2-octyldodecanol branched c20 skeleton provides the lowest skin drag, fastest spreading, and most elegant non-greasy feel in the cosmetic ester range, making it the reference standard for high-performance emollient texture.
How It Works: Octyldodecyl branching: c8 + c12 chains at c2 position โ molecular footprint mismatch โ reduced crystal packing โ liquid at skin temperature โ rapid spreading with negligible film residue.
Typically Found In: Premium skin care,serums,luxury formulas
