Emulsifier S-185\/O-5 (chemical name: fatty alcohol polyoxyethylene ether, CAS No.: 68439-49-6) is a white to pale yellow paste with high active content and low moisture. Its excellent emulsifying, wetting, dispersing, and solubilizing capabilities enable it to effectively reduce interfacial tension and enhance the stability of multiphase systems. Meanwhile, this product possesses good acid resistance, alkali resistance, and hard water tolerance, and exhibits good compatibility with anionic, cationic, and other nonionic surfactants, offering flexible formulation and adapting to various complex industrial recipes.
In practical applications, S-185\/O-5 is primarily used as a high-efficiency emulsifier, wetting agent, and dispersant, significantly accelerating the spreading and penetration of treatment liquids on substrate surfaces, ensuring uniform and stable multiphase systems, and maintaining stable performance in acidic, alkaline, and hard water environments, thereby reducing the amount of additives and lowering overall costs.
| Application Industry | Specific Process\/Product | Function |
|---|---|---|
| Pesticide Formulation | Emulsifiable Concentrate, Emulsion in Water, Microemulsion | Provides excellent emulsifying and dispersing properties, enhances formulation stability, and ensures uniform distribution of active pesticide ingredients during dilution and application. |
| Industrial Hard Surface Cleaning | Metal, plastic and other hard surface cleaners | Possesses good emulsifying and stripping capability for mineral oils, animal and vegetable oils and other greases, improving cleaning efficiency. |
| Metalworking Fluids | Cutting fluids, grinding fluids, rust preventives | As emulsifier and lubricating component, helps form stable emulsions, reduces friction and wear, improves cooling and rust prevention. |
| Textile Printing and Dyeing | Pretreatment, scouring agent, leveling agent, finishing auxiliaries | Effectively disperses oil stains and impurities on fibers, promotes uniform dye uptake, improves printing and dyeing quality. |
| Leather Processing | Degreasing process, fatliquoring process | Efficiently emulsifies natural fats in degreasing; promotes uniform penetration of oils in fatliquoring, enhancing leather softness and hand feel. |
| Coatings and Inks | Pigment dispersion in water-based coatings and water-based inks | Helps resin and pigment stably disperse in the aqueous phase, improving leveling, storage stability, and film-forming performance. |
In actual formulation design, it is recommended to reasonably adjust the addition amount of S-185\/O-5 according to the water-oil ratio of the system and the required HLB value. In pesticide microemulsions and emulsions in water, this product is usually used in combination with nonionic and anionic surfactants to achieve the best emulsification stability. In metalworking fluids, it can be used in synergy with rust inhibitors and extreme pressure additives to build a high-performance emulsion system. In textile scouring and leveling processes, it is recommended to use it together with alkali agents or other auxiliaries depending on the fiber type and degree of soiling to fully exert its penetration and dispersion effects.
