PPG-30
What is PPG-30?
PPG-30 is a synthetic oligomer of polypropylene glycol, formed by polymerizing propylene oxide units, typically around 30 repeats, resulting in a low-molecular-weight polyether from petrochemical origins. In cosmetics, it appears in moisturizers, lotions, serums, and hair products within the skin conditioning category. It works as a humectant by binding water molecules to the skin's surface, preventing moisture loss, while also acting as a solvent to enhance ingredient solubility and as an emollient to soften the skin barrier. This provides a silky, non-sticky texture, aiding even application without greasiness. Its small size allows penetration for better hydration retention, supporting skin flexibility and smoothness in formulations.
