The recommended dosage of Isomeric Alcohol Ether Phosphate E-1310P should be determined based on the specific application field and formulation system. There is no unified fixed dosage data available in the actual product database.
Detailed Description
Isomeric Alcohol Ether Phosphate E-1310P is a widely used anionic surfactant, playing a key role in fields such as metalworking fluids, textile auxiliaries, leather chemicals, pesticides, and daily chemicals due to its excellent extreme pressure lubricity, strong penetration and wetting ability, and outstanding chemical stability. Its usage method and recommended dosage highly depend on the specific product type you are developing, the synergistic effects of other components in the formulation, and the final performance standards expected. Therefore, it is impossible to provide a "universal" dosage applicable to all scenarios; the optimal amount must be determined through targeted experiments.
The following recommended dosages are based on Guoli Chemical's professional experience accumulated from long-term application testing of this product and are suitable for common formulation systems. In practice, you should use this range as a starting point and adjust it based on the evaluation results of your own system to achieve the optimal balance of performance and cost-effectiveness.

Application Recommendations
For different application fields, we recommend the following starting dosages (based on the total weight of the concentrate/formulation):
- Metalworking Fluids (Extreme Pressure Lubricant): Recommended dosage is 3% - 8% of the total formulation. As a boundary lubricant, it provides critical protection under high loads, effectively extending tool life and improving workpiece surface finish. When preparing the diluted working fluid, the effective concentration in the sump is usually maintained at 0.5% - 2%.
- Textile Dyeing and Finishing Pretreatment (Scouring Agent/Penetrant): Recommended dosage is 5% - 15% of the total formulation. Its high penetrability and alkali resistance enable it to quickly penetrate fibers, efficiently removing cotton wax and impurities. In continuous or batch scouring processes, the recommended dosage in the working bath is 1-3 g/L.
- Leather Processing (Degreasing Agent): Recommended dosage is 10% - 20% of the total formulation. It can quickly emulsify natural fats inside and outside the hide, acting gently to ensure degreasing effect without affecting the softness and fullness of the finished leather.
- Pesticide Formulations (Emulsifier): Recommended dosage is 3% - 8% of the total formulation. It is usually used in combination with compatible nonionic emulsifiers to obtain stable emulsions and good spray liquid spreading properties, improving pesticide utilization efficiency.
- Industrial and Household Cleaning Agents: Recommended dosage is 1% - 5% of the total formulation. In heavy-duty cleaning or metal surface treatment formulations, its excellent degreasing and decontamination capabilities can be fully utilized, and the low foaming property helps reduce rinsing difficulty.
Usage Process Tips: Since E-1310P has high viscosity at room temperature (200-500 mPa·s) and is acidic, it is recommended to first add a certain amount of water or liquid material into the mixing tank equipped with stirring, then slowly add this product under stirring. For systems sensitive to acidity, neutralize with an appropriate amount of alkaline substances (such as triethanolamine, sodium hydroxide, etc.) to the required pH value before use to improve its compatibility and solubility.
Precautions
- Safety Protection: E-1310P is classified as skin and eye irritant category 2. Must wear chemical safety goggles, chemical-resistant gloves (such as nitrile rubber), and protective clothing during operation. Ensure good ventilation in the workplace.
- Storage Recommendations: Store in a cool, dry, and well-ventilated place at 5-40°C, keep the container tightly sealed, and keep away from strong oxidizing agents. Use containers made of stainless steel, polyethylene (PE), or polypropylene (PP); avoid contact with carbon steel, aluminum, and copper materials.
- Environmental Disposal: Although the product has good biodegradability, it contains phosphate ester components. Wash waste liquid must not be directly discharged into sewers or surface water without treatment; it must be disposed of in an environmentally friendly manner according to local regulations.
