The alcohol ether carboxylate (yy易游体育) with molecular formula of R-(CH2CH2O)nOCH2COOX(H), is a new functional an-nonionic surfactant developed during the research of 9th Five-Year National Science and Technology Plan. yy易游体育 has excellent solubility in water and extremely strong ability of calcium soap dispersion. It remains stable not only in hardwater, acidic/alkali/electrolyte solution, but at high temperature or to hypochlorous acid/peroxide. Meanwhile, yy易游体育 is non-toxic, mild to skin and eyes as well as biodegradable; the degradation rate by OECD test is 98%. Addition of yy易游体育 may significantly improve the safety of the formula. yy易游体育 is applicable in daily chemical and industrial fields such as textile printing, aqueous metal cutting fluid, tertiary oil recovery, crude oil dilivering, developing solution, and so on.
There are two types of yy易游体育 products. One is the yy易游体育 produced through carboxymethylation, the other is by catalytic oxidation. Particularly, the catalyticly oxidized yy易游体育 is free of (sodium) chloroacetic acid, reaching the cosmetic level, can be used in personal care, cosmetics and infant washing products.
