PPG-9 Diglyceryl Ether

What is PPG-9 Diglyceryl Ether?

PPG-9 Diglyceryl Ether is a synthetic emollient ingredient produced by reacting diglycerol—a dimer of glycerol—with nine units of propylene oxide. This creates a branched, polyether structure that is moderately hydrophilic and lipophilic, ideal for cosmetic applications. Primarily used in moisturizers, lotions, serums, and hair conditioners within the skincare and haircare categories, it functions by depositing a thin, flexible film on the skin or hair. This film reduces surface friction, enhances product spreadability, and provides a smooth, velvety sensory experience without greasiness. As it mimics natural skin lipids, it aids in maintaining suppleness and flexibility, helping to counteract dryness-induced roughness while allowing better penetration of active ingredients.
