Polyoxyethylene(3) ether

Updated: 2026-07-29

Overview

Polyoxyethylene Ether 3 Emulsifier is a non-ionic surfactant known for its versatile emulsifying and wetting capabilities. It is widely used across various industries due to its ability to stabilize emulsions and enhance the mixing of immiscible liquids. The compound is particularly favored for its mildness and compatibility with a range of other chemicals. This emulsifier is synthesized through the ethoxylation of fatty alcohols, resulting in a product that balances hydrophilic and lipophilic properties. Its effectiveness in reducing surface tension makes it a staple in formulations requiring stable emulsions, such as in cosmetics and agricultural sprays.

Physical and Chemical Properties

Polyoxyethylene Ether 3 Emulsifier typically appears as a colorless to pale yellow liquid with a mild odor. It is soluble in both water and most organic solvents, which enhances its applicability in diverse formulations. The compound's density ranges between 1.02 and 1.05 g/cm³, depending on the specific formulation and purity. Key chemical properties include its non-ionic nature, which ensures compatibility with a wide range of other surfactants and chemicals. Its emulsifying efficiency is attributed to the ethoxylation degree, which can be adjusted to meet specific application requirements. The emulsifier is stable under normal storage conditions but should be protected from extreme temperatures and prolonged exposure to sunlight.

Main Applications

The textile industry utilizes Polyoxyethylene Ether 3 Emulsifier in dyeing and finishing processes, where it aids in the even distribution of dyes and other chemicals. Its ability to reduce surface tension ensures uniform penetration of dyes into fabrics, resulting in vibrant and consistent colors. In the cosmetics industry, this emulsifier is a key ingredient in lotions, creams, and shampoos, where it helps blend oil and water phases. Its mildness makes it suitable for skin-contact applications. Additionally, the agricultural sector employs it in pesticide formulations to improve the spreading and adhesion of active ingredients on plant surfaces.

Safety and Storage

While Polyoxyethylene Ether 3 Emulsifier is generally considered safe for industrial use, proper handling is essential to minimize risks. Direct contact with eyes or skin should be avoided, and protective gloves and goggles are recommended during handling. In case of exposure, rinse thoroughly with water and seek medical advice if irritation persists. Storage should be in a cool, dry place, away from direct sunlight and sources of ignition. Containers must be tightly sealed to prevent contamination and moisture absorption. The emulsifier is stable under normal conditions, but prolonged exposure to high temperatures may affect its performance.

B2B Procurement Guide

When procuring Polyoxyethylene Ether 3 Emulsifier, it is crucial to verify the product's purity and compatibility with your specific applications. Reputable suppliers should provide certificates of analysis (CoA) detailing the chemical composition and any impurities. Bulk purchases may offer cost advantages, but ensure proper storage facilities are available to maintain product integrity. Price ranges vary depending on quantity and supplier, but industry standards typically quote between $2.5 and $4.5 per kilogram. Consider sampling before large-scale procurement to confirm performance in your formulations. Additionally, inquire about customization options, as some suppliers offer tailored ethoxylation degrees to meet unique requirements.
