Common Name(s): Crodamol sts,light conditioning ester,cetearyl branched ester

CAS Number: 91219-76-2

DESCRIPTION

What It Does: Provides light silky emolliency combining isononanoate lightness with cetearyl conditioning.

Why It's Used: Light conditioning ester — uniquely combines the lightness of branched-acid esters with the skin conditioning of fatty alcohol esters in one ingredient, providing both feel attributes simultaneously.

How It Works: Cetearyl alcohol (c16+c18) + isononanoic acid (3,5,5-trimethylhexanoic) ester. light feel: branched acid. conditioning: cetearyl component. non-greasy. cosmos accepted. crodamol sts: commercial reference.

Typically Found In: Light emollient serums,skin care,body lotion

SAFETY & COMPATIBILITY

Safety Profile: Excellent safety profile. ewg score: 1.

Works Well With: Humectants,ceramides,actives as carrier

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Cetearyl isononanoate's dual feel profile from two molecular components: isononanoate acid branching provides lightness (prevents ordered surface film); cetearyl alcohol provides conditioning (long-chain skin interaction). same ester linkage delivering both properties — emollient design combining complementary components.
