Common Name(s): Pca glyceryl oleate,pca glyceryl oleate,dual-function nmf-emollient,pyroglutamic acid ester
CAS Number: N/a
DESCRIPTION
What It Does: Provides simultaneous nmf-compatible pyroglutamic acid humectancy and glyceryl oleate emolliency from a single bifunctional molecule.
Why It's Used: Pca glyceryl oleate is selected for its molecular dual function โ the pca moiety provides the same hygroscopic water-binding as the dominant nmf component while the glyceryl oleate moiety provides sc lipid-compatible emolliency, delivering two independent moisture retention mechanisms from one ingredient.
How It Works: Pca glyceryl oleate: pca carboxylate h-bond water binding โ nmf humectancy; glyceryl oleate ester โ sc lipid bilayer emolliency; combined โ dual-mechanism moisture retention from single molecule.
Typically Found In: Moisturiser,nmf replenishment
