About Nonylphenol

Nonylphenols, from the Latin nAnus (number 9) and phenol, are a family of closely related organic compounds composed of phenol bearing a 9 carbon-tail. Nonylphenols can come in numerous structures, all of which may be considered alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers.[2] These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics. Nonylphenol has attracted attention due to its prevalence in the environment and its potential role as an endocrine disruptor and xenoestrogen, due to its ability to act with estrogen-like activity.[3] The estrogenicity and biodegradation heavily depends on the branching of the nonyl sidechain.[4][5][6] Nonylphenol has been found to act as an agonist of the GPER (GPR30).

Key Properties and Appearance

Nonylphenol is a moderately polar liquid at room temperature with a density of 0.960 g/cm3. It has a refractive index of 1.4941.500 at 25C, a melting point of -8.4C, and is clear to pale yellow in appearance. It exhibits a characteristic phenolic odor. The compound is insoluble in water but readily soluble in most organic solvents, making it highly useful for industrial blending and formulation processes.

Applications and Usages

Predominantly used in the manufacture of surfactants, Nonylphenol is also integral to producing epoxy resin hardeners, antioxidants, and detergent intermediates. As a raw material derived from phenol and nonene, it is widely utilized in detergents, emulsifiers, plastics, lubricating oils, and pesticide formulations. Its effectiveness in industrial processes stems from its chemical stability and high purity.

Storage, Stability, and Safety Information

Store Nonylphenol in HDPE drums, steel drums, or ISO tanks, in a cool, dry, well-ventilated area, away from heat and ignition sources. The product remains stable under recommended conditions for up to 24 months. As it is classified as harmful and dangerous to the environment, proper handling, storage, and disposal are crucial to prevent environmental contamination and personal exposure.

FAQs of Nonylphenol:

Q: How is Nonylphenol used in industrial applications?

A: Nonylphenol serves as a key ingredient in the manufacture of surfactants, epoxy resin hardeners, antioxidants, and detergent intermediates. It is blended or formulated into finished products for use in detergents, emulsifiers, plastics, lubricating oils, and certain pesticide formulations.

Q: What are the safety precautions for handling Nonylphenol?

A: Due to its classification as harmful and hazardous to aquatic life, Nonylphenol should be handled in well-ventilated areas using appropriate personal protective equipment. Avoid contact with skin and eyes, and ensure the material is stored away from heat and ignition sources.

Q: Where should Nonylphenol be stored to maintain its stability?

A: Nonylphenol should be kept in cool, dry, and well-ventilated environments, preferably in HDPE drums, steel drums, or ISO tanks. Avoid direct sunlight and sources of heat to maintain product stability throughout its 24-month shelf life.

Q: What regulatory requirements apply to Nonylphenol?

A: Nonylphenol is subject to strict regulations, including REACH and other international chemical safety standards, due to its potential environmental hazards. Importers, distributors, and manufacturers must ensure compliance with all relevant legislation, such as proper labeling, handling, and reporting.

Q: What is the process for using Nonylphenol in formulations?

A: Nonylphenol can be incorporated into industrial processes by blending and formulation according to product specifications. It is commonly used as a raw material in the creation of detergents, surfactants, and polymer additives, following standard industrial protocols.

Q: What benefits does Nonylphenol offer in industrial products?

A: Nonylphenol enhances the performance of surfactants, resins, and plastic compounds by improving stability, effectiveness, and overall formulation flexibility. Its chemical properties contribute to the efficiency and quality of end-use applications.
