Common Name(s): Trimethylolpropane tricaprylate/tricaprate,trimethylolpropane caprylic/capric acids (c8/c10 mixed tricaprylate/tricaprate) ester
DESCRIPTION
What It Does: Softens skin with a ultra-lightweight non-greasy; mixed short c8/c10 chains on tmp; mct-like emolliency emollient texture.
Why It's Used: Trimethylolpropane ester of caprylic/capric acids (c8/c10 mixed tricaprylate/tricaprate); ultra-lightweight non-greasy; mixed short c8/c10 chains on tmp; mct-like emolliency; branched polyol ester reduces greasiness.
How It Works: Tmp provides a trifunctional branched core; caprylic/capric acids (c8/c10 mixed tricaprylate/tricaprate) provides emolliency; branched structure reduces crystallinity.
