Nonoxynol 9.5

Description :

Overview of Nonoxynol 9.5

Nonoxynol 9.5 is a nonionic surfactant and emulsifier widely used in pharmaceutical, cosmetic, personal care, and industrial formulations. It belongs to the alkylphenol ethoxylate family and is known for its excellent wetting, solubilising, cleansing, and emulsifying properties. Due to its balanced hydrophilic–lipophilic nature, Nonoxynol 9.5 is effective in oil-in-water systems and liquid formulations.

Nonoxynol 9.5 does not have a single fixed CAS number because it is an ethoxylated mixture, but it is commonly referenced under the Nonoxynol group. It is typically supplied as a clear to pale yellow liquid with good water solubility. It is often used in combination with ingredients such as Polysorbates, PEG derivatives, fatty alcohol ethoxylates, emulsifiers, and solubilisers to enhance formulation stability and performance.

Application of Nonoxynol 9.5

Pharmaceutical Applications

Nonoxynol 9.5 is used in topical pharmaceutical formulations, antiseptic solutions, and cleansing preparations due to its surfactant and solubilising properties. It helps disperse active ingredients uniformly and improves product effectiveness.

Cosmetic and Personal Care Products

In cosmetics, it is commonly used in shampoos, body washes, facial cleansers, liquid soaps, creams, and lotions. It improves cleansing efficiency, emulsification, and product clarity while maintaining mildness when formulated correctly.

Industrial and Household Applications

Nonoxynol 9.5 is widely used in industrial cleaners, detergents, textile processing, agrochemical formulations, and surface treatment products. It provides excellent wetting and emulsifying action in demanding applications.

Speciality and Functional Applications

It is also used in emulsion polymerisation, laboratory formulations, and speciality chemical blends, where stable emulsions and effective solubilization are required.

Safety and Handling Guidelines

• Store in a cool, dry, well-ventilated area

• Keep containers tightly closed

• Avoid prolonged skin and eye contact

• Use protective gloves and goggles during bulk handling

• Follow recommended concentration limits in formulations

When handled and formulated correctly, Nonoxynol 9.5 is stable, effective, and reliable for cosmetic, pharmaceutical, and industrial use.
