The main component of the isomeric alcohol ether phosphate E-1310P is isotridecanol polyoxyethylene (10) ether phosphate, which is an anionic surfactant.

Detailed Description

The effective ingredient of isomeric alcohol ether phosphate E-1310P is Isotridecanol Polyoxyethylene (10) Ether Phosphate (English name: Isotridecanol Polyoxyethylene(10) Ether Phosphate), belonging to the phosphate ester anionic surfactant category. Its molecular structure consists of three parts: the hydrophobic isotridecanol chain segment, the hydrophilic polyoxyethylene (EO) chain segment (average EO addition number about 10), and the terminal phosphate ester group. This unique "hydrophobic-hydrophilic-anchoring" molecular design endows the product with excellent interfacial activity and multifunctionality.

Since the raw material isotridecanol itself is a mixture of various isomers (branched chains at different carbon positions), the final product is also a mixture system containing different isomers. The product may also contain small amounts of unreacted free alcohol, free phosphoric acid, and a mixture of monoester and diester, which are normal characteristics of the phosphation reaction. Among them, a higher proportion of monoester leads to better emulsifying, wetting, and penetrating properties; diester contributes more lubricating and antistatic performance. E-1310P is usually dominated by monoester to ensure its excellent comprehensive application performance.

The appearance of the product is a colorless to light yellow transparent liquid at room temperature, with a slight characteristic odor. The active ingredient content is usually high (the specific content value is not available in this parameter; please contact the technical department of Guoli Chemical for batch inspection reports).

Application Suggestions

Based on the molecular structure characteristics of isotridecanol polyoxyethylene (10) ether phosphate, the core application scenarios of E-1310P include:

  • Metalworking fluids: As an extreme pressure lubricant in water-based or semi-synthetic cutting and grinding fluids, the phosphate ester group forms a chemically adsorbed protective film on the metal surface, significantly reducing the friction coefficient.
  • Textile printing and dyeing auxiliaries: Used as pretreatment scouring agent and penetrant, utilizing its excellent wetting and penetrating ability to efficiently remove cotton fiber wax and impurities.
  • Leather degreasing agent: Emulsifies and removes natural oils from raw hides.
  • Pesticide emulsifier: Enhances the dispersion and spreading ability of pesticide active ingredients in water.
  • Industrial cleaners: Combines oil removal, decontamination, and low-foam properties, suitable for heavy-duty cleaning and metal pretreatment.

Precautions

This product is classified as a skin and eye irritant (GHS Category 2). When handling, wear chemical safety goggles and chemical-resistant gloves (e.g., nitrile rubber). Storage temperature is recommended at 5°C to 40°C. Container materials should be stainless steel, polyethylene (PE), or polypropylene (PP). Avoid using carbon steel, aluminum, or copper containers.
