Octyl Pyrrolidone (NOP) (CAS 2687-94-7) is a pyrrolidone-based surfactant that appears as a clear, colorless to yellow liquid and combines pyrrolidone solvency with non-ionic wetting action, serving as a low-foam wetting agent, solvent and penetration enhancer in industrial cleaning, personal care and agrochemical formulations. Available in 99% purity , it is exceptionally effective at lowering surface tension in aqueous systems. This clear liquid acts as a powerful wetting agent and foam stabilizer, making it a preferred component in low-foam industrial cleaners. It possesses unique solvency for organic soils and is highly stable across a wide pH range. Its dual functionality as both a solvent and a surfactant makes it a high-value additive for technical textile processing and agrochemical delivery.
