n-octyl pyrrolidone

N-Octyl Pyrrolidone (CAS 2687-94-7), commonly abbreviated as NOP, is a high-boiling, low-volatility pyrrolidone solvent used in pharmaceutical, coatings, and personal care manufacturing.

Where is n-octyl pyrrolidone used?

• Coatings and adhesives: improves pigment dispersion and substrate wetting, enabling more uniform film formation on difficult surfaces including plastics and metals
• Personal care: solvent and penetration enhancer in topical products such as hair treatments
• Skin conditioners: aids active ingredient delivery
• Pharmaceutical manufacturing: supports drug solubilization and membrane permeation in transdermal and topical dosage forms
• Industrial cleaning and agrochemical formulations: emulsification and surface-modification properties that improve active distribution and contact efficiency
• It functions as a solvent, wetting agent, and dispersant where conventional solvents present regulatory or performance limitations.

Good to know: Buyers should confirm purity specifications and regulatory compliance documentation when sourcing for regulated end markets; REACH registration status is essential for compliance.

Commercial specifications

• Technical-grade material is the primary commercial form for most industrial and chemical processing needs
• High-purity grades are available for pharmaceutical and personal care applications
