A polyether copolymer of PEG-7 and PPG-2 with propylheptyl alcohol. Serves as a solubilizer and emollient in cosmetic formulations, improving the dispersion of oil-soluble ingredients in water-based products. It provides a smooth, silky after-feel and is commonly used in lightweight serums and facial mists.
