PEG-7 Propylheptyl Ether
What is PEG-7 Propylheptyl Ether?
PEG-7 Propylheptyl Ether is a synthetic compound formed by ethoxylating propylheptyl alcohol with seven units of ethylene oxide, creating a polyethylene glycol ether. This structure gives it amphiphilic properties, with a hydrophobic alkyl chain and hydrophilic PEG segment. In cosmetics, it falls under surfactants and emulsifying agents, commonly used in cleansers, shampoos, and light lotions. It functions by lowering surface tension between immiscible phases, enabling stable oil-in-water emulsions and improving the dispersion of hydrophobic ingredients like fragrances or oils in aqueous systems. This enhances product consistency, spreadability, and mild cleansing without stripping the skin barrier. Its low molecular weight contributes to gentle performance in rinse-off and leave-on products.
