Isosteareth-200 Linoleate
What is Isosteareth-200 Linoleate?
Isosteareth-200 Linoleate is a synthetic ingredient formed by esterifying a polyethylene glycol ether of isostearyl alcohol—derived from fatty sources—with linoleic acid, an unsaturated fatty acid from plant oils. Featuring 200 ethylene oxide units, it possesses strong hydrophilic properties, classifying it as a nonionic surfactant. In cosmetics, it belongs to the emulsifying and solubilizing agent category, commonly found in lotions, creams, and serums. It functions by reducing surface tension between oil and water phases, enabling stable emulsions that prevent separation. Additionally, it acts as an emollient, imparting a silky texture and aiding even distribution on the skin. This makes it valuable in lightweight formulations where smooth application and clarity are desired, supporting overall product performance without heavy residue.
Benefits
