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).
