Nonylphenol[2]

Updated: 2026-09-18

Overview

Nonylphenol is an organic compound belonging to the alkylphenol family. It is primarily used in the production of nonylphenol ethoxylates (NPEs), which serve as surfactants in various industrial and consumer applications. Due to its endocrine-disrupting properties, its use has been restricted in many countries, particularly in consumer products. The compound has been the subject of environmental and health concerns, leading to increased regulation and the development of alternative surfactants. Despite these challenges, nonylphenol remains an important industrial chemical in specific applications where alternatives are not yet viable.

Physical and Chemical Properties

Nonylphenol is a viscous liquid at room temperature with a faint phenolic odor. Its chemical structure features a phenolic group attached to a nonyl chain, which can vary in branching. This structure contributes to its surfactant properties, making it effective in reducing surface tension between liquids or between a liquid and a solid. The compound is relatively stable under normal conditions but can decompose when exposed to strong oxidizing agents. Its solubility characteristics make it particularly useful in formulations where water-insoluble components need to be emulsified or dispersed.

Main Applications

The primary use of nonylphenol is in the manufacture of nonylphenol ethoxylates, which are widely used as surfactants in industrial cleaners, agricultural chemicals, and textile processing. These derivatives account for the majority of nonylphenol consumption worldwide. Other applications include its use as an intermediate in the production of resins, as a stabilizer in plastics, and in some specialized lubricant formulations. However, many of these applications are being phased out in favor of less environmentally problematic alternatives in regions with strict chemical regulations.

Safety and Storage

Nonylphenol requires careful handling due to its potential health and environmental effects. It is classified as harmful if swallowed and can cause skin and eye irritation. Proper personal protective equipment, including gloves and eye protection, should be used when handling the chemical. Storage should be in tightly sealed containers made of compatible materials (typically stainless steel or certain plastics) in a cool, well-ventilated area. Containers should be clearly labeled, and measures should be taken to prevent any release into the environment, particularly waterways.

B2B Procurement Guide

When procuring nonylphenol, buyers should first verify that its use is permitted in their region and for their intended application. Many jurisdictions have restrictions on its use, particularly in consumer products. Technical specifications should be carefully reviewed, with attention to purity levels and isomer distribution. Suppliers should be able to provide comprehensive safety data sheets and documentation of regulatory compliance. Given the environmental concerns associated with this chemical, many buyers are actively seeking alternative surfactants, which may affect long-term availability and pricing.
