Isomeric Tridecanol Phosphate E-1306P is an anionic surfactant prepared by the addition of ethylene oxide (n≈6) to isomeric tridecanol as the starting material, followed by phosphorylation esterification. Its molecular structure contains both polyoxyethylene ether segments and phosphate ester groups, endowing the product with unique amphiphilic properties—it not only provides excellent emulsifying and dispersing power but also possesses the extreme pressure lubrication, anti-rust, and corrosion inhibition functions characteristic of phosphate esters. The effective content of the product is ≥95%. It is readily soluble in water and maintains stable chemical activity in acidic, alkaline, and hard water systems, without easy hydrolysis or precipitation.
The most outstanding feature of this product is its excellent extreme pressure lubricity, which effectively reduces the friction coefficient under severe boundary lubrication conditions, significantly minimizing wear caused by direct metal-to-metal contact, thereby extending the service life of tools and molds. Additionally, E-1306P exhibits outstanding penetration and wetting capabilities, allowing rapid spreading on substrate surfaces. It is especially suitable for deep hole and narrow slit treatment in complex geometric structures, ensuring uniform coverage of the treatment solution. It is a low-foaming surfactant, and when used in circulation systems, it does not generate excessive foam, which helps maintain process stability.
In terms of safety, E-1306P is an acidic anionic phosphate ester that is irritating to the skin and eyes. During operation, it is necessary to wear impermeable gloves, chemical safety goggles, and appropriate protective clothing, and ensure good ventilation in the workplace. This product is harmful to aquatic life and must not be discharged directly into water bodies without treatment. The recommended storage temperature range is 5°C–40°C. It should be stored sealed in corrosion-resistant containers such as stainless steel or polyethylene, away from strong oxidizers and strong alkalis.
