Description
N-Octyl-2-Pyrrolidone (CAS 2687-94-7, EC 403-700-8) is a lactam-based surfactant sold under trade names including Surfadone LP 100 and AgsolEx 8, also referred to as N-Octylpyrrolidone or N-Octylbutyrolactam. It carries no assigned E-code and has the molecular formula C12H23NO.
In coatings and adhesives, N-Octyl-2-Pyrrolidone reduces surface tension to improve substrate wetting and pigment dispersion without acting as a conventional solvent. In personal care formulations, it functions as a skin conditioner and emulsion stabilizer by integrating into interfacial films, and its UV-absorbing capacity provides secondary photoprotection in topical products.
N-Octyl-2-Pyrrolidone is supplied as a clear liquid and is registered under REACH. It is available in standard industrial drum and IBC packaging. Procurement teams should confirm grade specifications and regional compliance documentation directly with the supplier, as pharmaceutical-grade requirements may apply for healthcare applications. HS code: 29339900.
