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.
