OPP-10 octylphenol polyoxyethylene ether phosphate is a light yellow to yellow viscous liquid at room temperature. It can be used directly or diluted with water as needed before adding to the formulation system. It combines the dual characteristics of non-ionic and anionic surfactants, maintaining good interfacial activity under acidic, alkaline, and hard water conditions, offering high flexibility in use and compatibility with various surfactants and additives.
When using, it is recommended to first mix OPP-10 with the aqueous phase components of the formulation and stir evenly, then add the oil phase or other components. For processes requiring heating, this product can maintain stable emulsifying performance at high temperatures, but prolonged heating above the decomposition temperature should be avoided. Due to its viscous nature, viscosity increases at low temperatures in winter. It is recommended to store and use at 20-30°C. If necessary, preheat with a warm water bath to reduce viscosity for accurate measurement and feeding.
The recommended dosage of this product varies in different application fields. The optimal dosage should be determined through experiments based on formulation requirements and actual process conditions.
| Application field | Recommended dosage (% of total formulation) | Usage method |
|---|---|---|
| Textile printing and dyeing antistatic agent/scouring agent | 2%-8% | Dissolve in water and other additives before use; can be added during padding or impregnation stages of fiber processing. |
| Metalworking fluids (cutting fluid/grinding fluid) | 3%-10% | Used as an emulsifier to formulate concentrates with base oils, rust inhibitors, etc.; dilute with water to working concentration before use. |
| Industrial and hard surface cleaners | 1%-5% | Formulate with alkaline additives, chelating agents, etc.; dissolve in water before use. Heating can improve cleaning effectiveness. |
| Pesticide emulsifiers (emulsifiable concentrate/emulsion in water) | 5%-15% | Mix evenly with pesticide technical material and solvent to prepare emulsifiable concentrate or emulsion in water, ensuring stable emulsification of active ingredients. |
| Personal care products (emulsifying solubilizer) | 0.5%-3% | Dissolve in the aqueous phase, then slowly add fragrance or oil components while stirring until transparent dispersion. |
| Emulsion polymerization | 1%-4% (based on monomer weight) | Add to the aqueous phase before polymerization to ensure uniform distribution of latex particles and emulsion stability. |
| Leather degreasing | 0.5%-2% | Prepare an aqueous solution and act on raw hides in a drum; best effect at 35-45°C. |
| Paint and ink wetting and dispersing agent | 0.2%-1% (based on pigment weight) | Add during the grinding and dispersion stage, grinding together with pigments and resin to promote uniform dispersion. |
Note: The above recommended dosages are common industry reference ranges. The optimal dosage should be determined through experiments based on the specific formulation and process conditions.
Formulation recommendations: OPP-10 is compatible with non-ionic surfactants (such as Peregal O series, TX series), anionic surfactants (such as LAS, AES), and cationic surfactants. It can also be used synergistically with cosolvents, chelating agents, corrosion inhibitors, etc. In metalworking fluid formulations, it is often formulated with rust inhibitors such as petroleum sulfonates and borate esters to enhance anti-rust performance.
Dilution recommendations: It is recommended to use deionized water or soft water for dilution to fully utilize its hard water resistance advantage. If hard water is used, OPP-10’s inherent hard water resistance can tolerate calcium and magnesium ions to a certain extent, but water quality optimization is still recommended for best results.
