Common Name(s): Butyl phthalyl butyl glycolate,cosmetic functional active,established formulation chemistry

CAS Number: N/a

DESCRIPTION

What It Does: Provides polyol humectant moisture retention, co-solvent dissolution of actives, and mild skin penetration enhancement.

Why It's Used: Polyol humectants/co-solvents are essential for moisture retention and active dissolution — the specific carbon chain and oh group arrangement determines water-binding capacity, viscosity contribution, and skin feel.

How It Works: Multiple hydroxyl groups form h-bonds with 5-7 water molecules per oh group providing hygroscopic moisture retention. alkyl chain length controls lipophilicity — short chains provide humectancy; long chains provide emolliency.

Typically Found In: Cosmetic formulations
