Common Name(s): Trimethylolpropane tricocoate,trimethylolpropane coconut fatty acids (mixed c8-c18 tricocoate) ester

DESCRIPTION

What It Does: Softens skin with a mixed-chain coconut oil analog on tmp backbone; lighter than coconut oil due to polyol ester structure emollient texture.

Why It's Used: Trimethylolpropane ester of coconut fatty acids (mixed c8-c18 tricocoate); mixed-chain coconut oil analog on tmp backbone; lighter than coconut oil due to polyol ester structure; branched polyol ester reduces greasiness.

How It Works: Tmp provides a trifunctional branched core; coconut fatty acids (mixed c8-c18 tricocoate) provides emolliency; branched structure reduces crystallinity.

Typically Found In: Skin care emollients,color cosmetics,anhydrous formulas
