PPG-11 Stearyl Ether
What is PPG-11 Stearyl Ether?
PPG-11 Stearyl Ether is a synthetic polymer formed by reacting stearyl alcohol, a long-chain fatty alcohol often sourced from plant or petroleum origins, with eleven units of propylene oxide. This creates a lightweight, water-dispersible ether that belongs to the polyalkylene glycol ether family commonly used in leave-on and rinse-off cosmetics like moisturizers, serums, and hair conditioners. In formulations, it functions by lowering surface tension, which enhances product spreadability and imparts a silky, non-greasy finish. It mimics the emollient properties of natural oils but with improved stability and reduced tackiness, helping to bridge water and oil phases in emulsions while providing a protective barrier that minimizes transepidermal water loss.
