PPG-9
What is PPG-9?
PPG-9, known chemically as poly(propylene glycol)-9, is a short-chain synthetic polymer produced through the polymerization of propylene oxide, a derivative of petroleum-based propylene glycol. This clear, odorless, viscous liquid belongs to the polyalkylene glycol family and is widely incorporated into cosmetic formulations such as moisturizers, serums, and cleansing products. It functions primarily by attracting and retaining moisture on the skin's surface, creating a protective barrier that minimizes transepidermal water loss. Additionally, its low viscosity aids in improving the texture and spreadability of products, allowing for even application and a non-greasy feel. As a versatile emollient, PPG-9 enhances the overall sensory experience of skincare items while supporting skin barrier integrity.
