Disabled: Fatty acid methyl ester ethoxylate FMEE contains large amounts of APEO

Thread Content

FMEE, an ethoxylated fatty acid methyl ester, has a strong ability to dissolve and remove mineral oil, and its production cost and price are low. It was widely used in the secondary oil recovery processes in oil drilling as well as in the cleaning of oil and gas pipelines in the early days, achieving good results. In recent years, fatty acid methyl ester ethoxylate FMEE, which has had impurities removed through distillation, has also begun to be utilized in other fields, particularly in the scouring process as a pretreatment for textile greige. As its use becomes more widespread, more and more customers have discovered that fatty acid methyl ethoxylate FMEE can cause excessive levels of nonylphenol APEO in the treated fabrics. The main reason for this is that FMEE, which is manufactured using mixed esters as raw materials, inevitably retains large amounts of nonylphenol APEO even after multiple distillation processes. Therefore, FMEE should be used with caution in industries such as textiles, printing, and papermaking.
