The usage method of isomeric alcohol ether phosphate E-1310P varies by application field, with the core being its direct addition to aqueous systems as a functional anionic surfactant, utilizing its extreme pressure lubricity and penetrating wetting properties to enhance product performance.
Detailed Description
Isomeric alcohol ether phosphate E-1310P is a high-efficiency, multifunctional anionic surfactant, appearing as a colorless to light yellow transparent liquid at room temperature. It is easily soluble in water and typically requires no special treatment before use. Its usage method heavily depends on the specific application scenario, but the general principle is to add it as a key functional component directly into the aqueous or oil-water mixed system at the appropriate stage of formulation preparation, and stir thoroughly. Thanks to its good chemical stability, it remains active over a wide pH range, especially performing excellently in alkaline environments (stable in 100g/L NaOH solution).
During formulation, attention should be paid to its 1% aqueous solution pH value of 2.0~3.0, which is acidic. Therefore, when used in alkaline formulations such as metalworking fluids or cleaning agents with specific pH requirements, it needs to be neutralized with alkaline substances (e.g., triethanolamine, potassium hydroxide, etc.) to achieve the desired pH balance point, which also further optimizes its emulsification, lubrication, and anti-rust properties.
Application Recommendations
According to the product data of Guoli Chemical and industry common practices, the following are specific usage methods and recommended addition amounts for E-1310P in different fields (the dosages below are internal experimental recommendations; actual adjustments should be made based on the formulation system):
- Metalworking Fluids (Cutting Fluids, Grinding Fluids): As a core extreme pressure lubricant, recommended addition amount is 3% - 10% of the total formulation. When preparing the concentrate, mix E-1310P with base oil, rust inhibitors, bactericides, etc., and finally dilute with water to form the working fluid. It significantly reduces the friction coefficient and extends tool life.
- Textile Printing and Dyeing Pre-treatment (Scouring Agents, Penetrants): As a highly effective penetrating and scouring component, recommended dosage in the scouring bath is 1 - 5 g/L. Add directly to water and stir evenly. Its strong penetrating power (canvas settlement method ≤10 seconds) helps quickly remove wax and impurities from cotton fibers, improving capillary effect and whiteness.
- Leather Processing (Degreasing Agents): Used in wet processing stages such as soaking and liming, recommended dosage is 0.5% - 2.0% of the hide weight. It can be directly added to the water bath in the drum, achieving uniform action through rotation, effectively emulsifying natural fats.
- Pesticide Formulations (Emulsifiers): As a key component of the emulsification system, recommended addition amount is 5% - 15% of the total formulation. Usually, it is first mixed with the pesticide technical material and solvent to form a uniform oil phase, then diluted with water or involved in emulsion polymerization to prepare stable and uniform emulsifiable concentrate (EC) or microemulsion (ME).
- Household and Industrial Cleaners: Used as a surfactant, recommended addition amount is 1% - 5%. It can be directly mixed with other surfactants, additives, and water. Especially suitable for metal surface treatment and heavy-duty cleaning scenarios requiring high penetration and low foaming.

Precautions
- Safety Protection: This product is classified as skin/eye irritant Category 2. Must wear chemical safety goggles and chemical-resistant gloves such as nitrile rubber during operation to prevent direct contact with skin and eyes.
- Storage Containers: Should be stored in sealed containers made of stainless steel, polyethylene (PE) or polypropylene (PP). Do not use carbon steel, aluminum, or copper containers to avoid corrosion from long-term contact.
- Compatibility: Chemically stable under normal conditions, but avoid contact with strong oxidizing agents to prevent reactions. When preparing alkaline formulations, it is recommended to first add it to water and stir evenly, then add alkali solution for neutralization.
- Emergency Treatment: In case of accidental eye contact, immediately rinse with plenty of water for at least 15 minutes and seek medical attention. Thoroughly wash exposed skin after use.
