Polyethylene-polypropylene glycol CAS#9003-11-6

Polyethylene-polypropylene glycol (PEPG) is a copolymer that combines the properties of both polyethylene and polypropylene with the hydrophilic nature of polyethylene glycol. It is known for its excellent compatibility with various substances and its ability to act as a surfactant, emulsifier, or dispersing agent. PEPG is used in pharmaceuticals, cosmetics, and industrial applications for its solubility, low toxicity, and stability. It enhances the performance of formulations by improving wetting, dispersion, and emulsification properties.
