  • Applications

    1-Lauryl-2-pyrrolidone (CAS 2687-96-9) is a polar, high-boiling solvent and amphiphilic processing aid. It is commonly used as a solvent or co-solvent for polymers and resins, helping dissolution or dispersion in plastics, coatings and adhesive formulations. It also functions as a surfactant and solubilizer in coatings, inks and cleaners, improving wetting, emulsification and cleaning performance. In cosmetics and personal care, it can act as a solvent and emulsifier for oils and active ingredients, contributing to formulation stability and texture. Additionally, it is evaluated as an intermediate solvent or processing aid in the synthesis and formulation of specialty chemicals. Use is subject to local regulations and formulation limits.
