Isomeric Alcohol Ether Phosphate E-1310P is an anionic surfactant, with core features including excellent extreme pressure lubricity, strong penetrating and wetting ability, superior chemical stability, and multi-functionality. It is a highly efficient multifunctional component for fields such as metalworking fluids and textile auxiliaries.
Detailed Description
Isomeric Alcohol Ether Phosphate E-1310P, chemically named isomeric tridecanol polyoxyethylene (10) ether phosphate, is an anionic surfactant. Its molecular structure incorporates the branched alkyl chain of isomeric tridecanol and a polyoxyethylene ether segment, modified by phosphation, endowing the product with unique interfacial activity and dual functions of extreme pressure lubricity. At room temperature, it appears as a colorless to light yellow transparent liquid with a slight characteristic odor.
The most prominent feature of this product is its extreme pressure lubricity — the ability to rapidly form a tough protective film on metal surfaces, significantly reducing the coefficient of friction, effectively preventing workpiece scoring and cold welding. It is a key component for formulating high-performance water-based or semi-synthetic metalworking fluids. Meanwhile, owing to the low surface tension characteristics brought by the branched chain structure, E-1310P exhibits strong penetrating and wetting ability, enabling it to spread quickly and penetrate into microscopic crevices. It performs excellently in applications such as textile pretreatment scouring and pesticide spreading.
Furthermore, E-1310P possesses excellent chemical stability — it remains active across a wide pH range, shows good tolerance to acids, alkalis, and hard water media, ensuring the reliability of formulations under different water quality conditions. It also integrates emulsifying, dispersing, and washing functions, achieving multi-functionality, which helps simplify formulation systems and reduce overall application costs.

Application Recommendations
- Metalworking Fluids: Used as an extreme pressure lubricant in water-based or semi-synthetic cutting fluids and grinding fluids. Add proportionally according to the formulation system to provide boundary lubrication protection, extend tool life, and improve workpiece surface finish.
- Textile Dyeing and Finishing Auxiliaries: Used in scouring agent and penetrating agent formulations for pretreatment processes, effectively removing cotton fiber waxes and sizing impurities, enhancing scouring uniformity and whiteness.
- Leather Degreasing: Applied in degreasing processes during wet stages such as soaking and liming, quickly emulsifying and removing natural oils from raw hides, achieving thorough degreasing without affecting leather softness.
- Pesticide Formulations: Used as an emulsifier component in emulsifiable concentrate or microemulsion formulations, enhancing the wetting and spreading ability of diluted spray on crop surfaces, improving efficacy.
- Industrial Cleaning: Used as a surfactant component in heavy-duty industrial cleaners and metal pretreatment agents, combining oil removal, dirt removal, and low-foaming characteristics.
Precautions
- This product is irritating to skin and eyes (GHS Category 2). When handling, wear chemical safety goggles, chemical-resistant gloves (e.g., nitrile rubber), and protective work clothing.
- Recommended storage temperature is between 5°C and 40°C. Containers should be made of stainless steel, polyethylene (PE), or polypropylene (PP). Avoid using carbon steel, aluminum, or copper containers, as prolonged contact may cause corrosion.
- Avoid contact or mixed storage with strong oxidizing agents, strong acids, strong bases, and other incompatible substances.
- In case of leakage, adsorb small spills with inert materials such as sand or vermiculite; for large spills, construct dikes to contain dispersion. Do not discharge washing wastewater directly into sewers or surface waters.
- This product has a biodegradability >60%, meeting biodegradable standards; however, avoid long-term and large-scale release into natural water bodies.
