The main component of Isotridecanol Phosphate Ester E-1306P is Isotridecanol Ethoxylate Phosphate Ester, an anionic phosphate ester surfactant with CAS number 9043-30-5.

Detailed Description

Isotridecanol Phosphate Ester E-1306P is an anionic phosphate ester produced by first using isotridecanol as the starting material, undergoing ethoxylation with ethylene oxide (EO) to form an isotridecanol ethoxylate intermediate, and then esterifying it with a phosphorylation agent (typically phosphorus pentoxide, P₂O₅). Its full chemical name is "Isotridecanol Ethoxylate Phosphate Ester," with aliases including tridecyl alcohol ether phosphate ester, isotridecyl ether phosphate ester, tridecyl polyether-6 phosphate ester, etc.

From a chemical structure perspective, this product mainly consists of a mixture of monoester and diester phosphates. The "6" in "E-1306P" indicates that the number of ethylene oxide (EO) units added is approximately 6 moles. The monoester phosphate imparts excellent emulsifying, dispersing, and antistatic properties, while the diester phosphate contributes outstanding extreme pressure lubrication and penetration capabilities. Their synergistic effect makes this product particularly effective in various fields such as metalworking fluids, industrial cleaners, and textile auxiliaries.

This product appears as a light yellow transparent viscous liquid, is acidic in nature, and maintains stable chemical activity and compatibility in acidic, alkaline, and hard water systems. It is not easily hydrolyzed or precipitated, offering wide system applicability.

Application Recommendations

Due to its main components possessing both the emulsifying and dispersing capabilities of monoester phosphates and the extreme pressure lubrication characteristics of diester phosphates, Isotridecanol Phosphate Ester E-1306P is particularly suitable for the following applications:

  • Metalworking Fluids: Used as an extreme pressure lubricant and corrosion inhibitor, significantly reducing friction and wear in emulsified oils, semi-synthetic, and full-synthetic cutting fluids.
  • Industrial Alkaline Cleaners: Leveraging its excellent alkaline resistance and penetration to quickly remove heavy oil stains and carbon deposits from metal surfaces.
  • Textile Printing and Dyeing Pretreatment: Used as a scouring agent and penetrant to promote uniform penetration of alkali liquor into fibers.
  • Pesticide Formulations: As an emulsifier to enhance the dispersion stability and dilution emulsification performance of technical materials.

Precautions

This product is an acidic anionic phosphate ester, which may cause skin irritation and serious eye irritation. When handling, wear impermeable gloves and chemical safety goggles. It is recommended to use in a well-ventilated area. For detailed safety information, please refer to the Safety Data Sheet (SDS).
