Choleth-24
What is Choleth-24?
Choleth-24 is a synthetic amphiphilic compound formed by attaching a chain of 24 ethylene oxide units to a cholesterol molecule, creating a lipophilic head from the cholesterol and a hydrophilic polyethylene glycol tail. This structure allows it to function as a non-ionic surfactant and emulsifying agent in cosmetics, particularly in oil-in-water emulsions like lotions, creams, and cleansing formulations. By lowering surface tension at the oil-water interface, it forms stable micelles or interfacial films that prevent phase separation, ensuring product consistency and even distribution during application. Commonly found in skincare for its ability to incorporate lipid components into watery bases, it supports the creation of lightweight yet moisturizing textures without compromising spreadability.
