What is OPP-10 Octylphenol Polyoxyethylene Ether Phosphate? What are its main uses?

OPP-10 Octylphenol Polyoxyethylene Ether Phosphate is a phosphate ester modified product with dual characteristics of nonionic and anionic surfactants, widely used in textile, metalworking, pesticide, cleaning and other industrial fields.

Detailed Description

OPP-10 Octylphenol Polyoxyethylene Ether Phosphate (CAS No.: 51811-79-1) is an anionic surfactant obtained by phosphate ester modification of octylphenol polyoxyethylene ether. It is also known as OP-10 phosphate ester, polyoxyethylene octylphenol ether phosphate (10EO), phosphorylated octylphenol polyoxyethylene ether, etc. The product appears as a light yellow to yellow viscous liquid. Its molecular structure contains both ether bonds and phosphate ester groups, giving it dual characteristics of nonionic and anionic surfactants.

The core performance of this product is prominently reflected in three aspects: excellent emulsifying ability, wetting and penetration, and dispersion stability. Benefiting from its unique molecular structure, OPP-10 maintains stable interfacial activity in complex water conditions and acidic/alkaline environments, exhibiting outstanding acid and alkali resistance and hard water tolerance. In addition, the product also shows good antistatic properties and certain anti-rust and corrosion inhibition effects, achieving a "multi-purpose" effect in formulations.

As one of the core products of Guoli Chemical, OPP-10 has good compatibility with various surfactants and auxiliaries, allowing flexible application in various formulation systems. Although the product is of low toxicity, it is mildly irritating to skin and eyes; it is recommended to wear protective gloves and goggles during operation. For detailed safety data, please refer to the product safety data sheet.

Application Suggestions

OPP-10 Octylphenol Polyoxyethylene Ether Phosphate has a wide range of applications, mainly including the following eight directions:

• Textile dyeing and printing: Used as antistatic agent and scouring agent, effectively eliminating static buildup during fiber processing and improving pretreatment effects on fabrics.
• Metalworking fluids: As emulsifier and rust inhibitor, suitable for cutting fluids, grinding fluids and other systems, providing stable emulsion structure and metal surface protection.
• Industrial and hard surface cleaning: Used in industrial cleaning agents and hard surface cleaning product formulations, enhancing emulsifying and dispersing ability for heavy oil stains and detergency.
• Pesticide formulations: As emulsifier in pesticide emulsifiable concentrates, water emulsions and other dosage forms, promoting stable emulsification of active ingredients in aqueous phase, improving formulation stability and spray liquid spreadability.
• Personal care products: Used as oil-in-water emulsifier or solubilizer, assisting transparent dispersion and solubilization of fragrances and oily ingredients in water-based systems.
• Emulsion polymerization: Providing good emulsification and particle stability in acrylic, styrene-acrylic and other emulsion polymerizations, improving mechanical and freeze-thaw stability of the emulsion.
• Leather processing: Used in leather degreasing process, effectively removing natural fats from raw hides while maintaining mild action to reduce damage to leather fibers.
• Coatings and inks: As wetting and dispersing agent, improving dispersion uniformity of pigments and fillers, preventing flocculation and floating/flooding.

Precautions

This product is irritating to skin and eyes. Wear protective gloves and chemical safety goggles during operation. It is combustible in contact with open flames and high heat; thermal decomposition may release toxic phosphorus oxide gases. Keep away from fire and high temperature environments. Storage temperature should not exceed 30°C, and store in a cool, ventilated place. It is very toxic to aquatic organisms with long-lasting effects; do not discharge into any water body without treatment.
