Description

Nonoxynol-3 Phosphate is a specialized nonionic surfactant phosphate ester, valued for its unique combination of emulsifying, wetting, and dispersing properties. This chemical is particularly significant as a versatile intermediate and functional additive in formulations requiring compatibility with aqueous systems and controlled surface activity. Key industries that utilize this product include agrochemicals, textile processing, industrial cleaning, and personal care, where it acts as an effective emulsifier and antistatic agent.

Application

• Primary emulsifier and dispersant in agricultural pesticide and herbicide formulations.
• Wetting and leveling agent in textile dyeing and finishing processes.
• Key component in industrial and institutional cleaning products for hard surface cleaning.
• Functional additive in metalworking fluids for lubrication and corrosion inhibition.
• Co-emulsifier and stabilizer in cosmetic and personal care products like creams and lotions.
• Antistatic agent and processing aid in polymer and plastic manufacturing.
• Intermediate for the synthesis of more complex phosphate ester surfactants.

Quality Control

Our Nonoxynol-3 Phosphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, assay, and impurity profiles. Certificates of Analysis (COA) documenting purity, phosphate content, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
