OP-10 (CAS number: 9036-19-5), chemical name octylphenol polyoxyethylene ether or polyoxyethylene(10) octylphenyl ether, aliases include emulsifier OP-10, polyethylene glycol octylphenyl ether, etc., is a similar substitute for Triton X-100. The product appears as a colorless to light yellow transparent liquid or paste, belonging to typical non-ionic surfactants, produced by Haian Guoli Chemical Co., Ltd.
The core advantage of OP-10 lies in its excellent comprehensive surface activity performance: it can efficiently reduce oil-water interfacial tension to form stable emulsions, significantly reduce liquid surface tension for rapid wetting, and at the same time have good suspension and dispersion effects on dirt particles. In addition, the product maintains stable performance over a wide pH range, has good hard water resistance, and excellent compatibility with various auxiliaries.
As an efficient non-ionic surfactant, it is widely used in formulations such as metal degreasers and hard surface cleaners, quickly wetting and emulsifying oil stains, significantly improving detergency, and is a core component in the field of industrial cleaning.
Used as a penetrating agent, leveling agent, and wetting agent in textile processing, it helps dye liquor uniformly penetrate into fibers, improving dyeing quality and processing efficiency, effectively reducing color difference and uneven dyeing.
Used in pesticide formulations such as emulsifiable concentrates and aqueous emulsions, it uniformly disperses active ingredients in the water phase, enhancing the stability and adhesion of the spray liquid, thereby improving application effect and pesticide utilization.
As a wetting dispersant and emulsion polymerization emulsifier, it improves the dispersion state of pigments in the system, prevents sedimentation and flocculation, and enhances the storage stability and application performance of coatings and inks.
OP-10 is also widely used in leather degreasers (effectively removing natural oils and process oils), paper machine felt cleaners and waste paper deinking agents (promoting ink separation and removal), crude oil demulsifiers and oilfield acidizing aids (helping oil-water separation and improving operational efficiency), and as a component in metalworking fluids (providing lubrication, cooling, and cleaning functions).
OP-10 can be used flexibly in formulations, either directly added to the water phase or oil phase. The specific dosage needs to be optimized according to the target system and process requirements. Generally recommended at 1%~10% in cleaning agent formulations, 5%~15% in pesticide emulsifiable concentrates, and 2%~8% in textile auxiliaries. It is recommended to verify the optimal addition amount through small-scale tests.
