Common Name(s): Polyglyceryl-2 isopalmitate/sebacate,pg-2 isopalmitate sebacate,mixed diester polyglycerol-2

DESCRIPTION

What It Does: Softens skin and helps oil and water blend with a light, non-greasy finish.

Why It's Used: Mixed diester of branched isopalmitate (reduces greasiness) and sebacate (diacid adds polarity and flexibility) on pg-2; unique sensory profile.

How It Works: Isopalmitate provides branching (non-greasy); sebacate diacid provides flexibility and some polarity; pg-2 glycerol head; overall lightweight emolliency.
