PEG/PPG-17/6 Copolymer
What is PEG/PPG-17/6 Copolymer?
PEG/PPG-17/6 Copolymer is a synthetic polyether compound formed by polymerizing ethylene oxide (17 units) and propylene oxide (6 units), creating a hydrophilic and lipophilic balanced molecule. In cosmetics, it belongs to the surfactant and solvent category, commonly found in cleansers, toners, and moisturizers. It functions by solubilizing both polar and non-polar substances, enabling stable emulsions and uniform distribution of active ingredients. Its amphiphilic nature allows it to reduce surface tension, control evaporation rates, and enhance product spreadability without leaving residue. This makes it versatile for formulating lightweight, non-greasy textures that penetrate skin effectively while maintaining clarity and stability across pH ranges.
