PEG/PPG-25/30 Copolymer
What is PEG/PPG-25/30 Copolymer?
PEG/PPG-25/30 Copolymer is a synthetic polymer created through the copolymerization of ethylene oxide and propylene oxide monomers, resulting in a water-soluble material with both hydrophilic and hydrophobic segments. In cosmetics, it belongs to the category of polyethers commonly used in formulations like cleansers, moisturizers, and styling products. It functions primarily by solubilizing lipophilic and hydrophilic substances, enabling uniform blending of diverse ingredients that might otherwise separate. Additionally, it modifies viscosity to achieve desired flow properties, enhances spreadability on skin, and stabilizes emulsions by reducing surface tension. This dual PEG/PPG structure allows it to bridge oil-water interfaces effectively, contributing to lightweight, non-greasy textures in rinse-off and leave-on products.
Roles in Formulation
