Common Name(s): Polyol alcohol,humectant co-solvent,skin conditioning diol

CAS Number: N/a

DESCRIPTION

What It Does: Provides skin hydration from hydroxyl group water-binding, co-solvent dissolution of actives, and emollient conditioning.

Why It's Used: Polyols provide versatile multi-function — humectancy, solubilisation, and penetration enhancement — from a single ingredient type.

How It Works: Oh groups form h-bonds with water molecules providing hygroscopic moisture retention. alkyl chain length and branching determines lipophilicity and skin feel — short chain polyols (glycerol, bg) → humectant; long chain (c12+) → emollient.

Typically Found In: All formulations
