Emulsifier A-105 (Nonylphenol polyoxyethylene (10) ether) is a high-performance nonionic surfactant that plays a key role in multiple industrial fields due to its excellent emulsifying, wetting, dispersing, and detergency capabilities. This product is obtained by the addition reaction of nonylphenol and ethylene oxide as main raw materials. The synergistic effect of ether bonds and hydroxyl groups in the molecular structure endows it with outstanding interfacial activity, showing good tolerance to acidic and alkaline media as well as hard water environments, thus maintaining stable performance under complex working conditions.
In the field of pesticide formulations, Emulsifier A-105 is a core auxiliary for emulsifiable concentrates, aqueous emulsions, and microemulsions. It can rapidly reduce the oil-water interfacial tension, promote the formation of a stable emulsion between oily technical materials and water, significantly enhance the spreading and penetrating properties of the spray solution, and ensure the field application effect and long-term storage stability of the formulation. In the textile dyeing and finishing industry, it performs dual functions as a leveling agent and a scouring agent—as a leveling agent, it can slow down the dye uptake rate to achieve uniform color; as a scouring agent, it can efficiently remove oils and impurities from the fabric surface.
In industrial cleaning and leather processing, Emulsifier A-105 also demonstrates outstanding performance. It can be compounded into hard surface cleaners for metals, glass, etc., strongly emulsifying and dispersing mineral oils and animal/vegetable fats, achieving rapid decontamination with good anti-redeposition ability. In the leather degreasing process, it can penetrate deeply into the leather fibers, gently and efficiently emulsify natural fats without damaging the hide, resulting in soft and full-grained leather. Additionally, this product is used as an emulsifier in metalworking fluids (cutting fluids, grinding fluids) and as the primary emulsifier in emulsion polymerization of monomers such as acrylates and styrene, playing an important role in ensuring uniform and stable latex particles and controlling particle size distribution.
| Industrial Field | Specific Process/Application | Function Description |
|---|---|---|
| Pesticide Formulations | Preparation of emulsifiable concentrates, aqueous emulsions, microemulsions | Efficiently emulsify oily technical materials, enhance dispersion, spreading, and penetration of spray solution, ensure storage stability |
| Textile Dyeing and Finishing | Leveling, scouring processes | Slow down dye uptake for uniform color; remove oils and stains from fiber surface, improve fabric cleanliness |
| Industrial Cleaning | Hard surface cleaners (metal, glass, etc.) | Strongly emulsify and disperse mineral oils and animal/vegetable fats, fast decontamination, anti-redeposition |
| Leather Processing | Raw hide degreasing pretreatment | Penetrate deeply into leather fibers, gently emulsify natural fats without damaging hide, resulting in soft and full-grained leather |
| Metalworking Fluids | Preparation of emulsified and micro-emulsified cutting/grinding fluids | Combine base oil with water into a stable working fluid, providing lubrication, cooling, and rust prevention properties |
| Emulsion Polymerization | Polymerization of monomers such as acrylates and styrene | Form and stabilize latex particles, control particle size distribution, improve mechanical and storage stability of polymer emulsion |
Emulsifier A-105 has good compatibility and can be compounded with anionic, cationic, and other nonionic surfactants for synergistic effects. In actual formulation design, it is recommended to adjust the dosage according to the HLB value requirement of the target system, with a typical addition amount of 2% to 10% of the total formulation. For pesticide emulsifiable concentrate systems, it can be used in combination with anionic emulsifiers (such as calcium salts) to obtain better emulsion stability; in metalworking fluid formulations, it should be used together with rust inhibitors, extreme pressure additives, etc., to construct multifunctional working fluids.
Since this product maintains stable performance over a wide pH range and under high hardness water conditions, it is especially suitable for industrial applications with complex water quality. In textile pretreatment processes, it can be used together with scouring agents under alkaline conditions; it is also applicable in acidic cleaning formulations without concerns of hydrolysis failure.
