Summary:Esterquats find major applications as fabric softeners. After Tallow fatty acids and Palm oil fatty acids, fatty acids from sustainable sources like Rice bran fatty acids (RBFA) are desired. RBFA is formed as a by-product during refining of Rice bran oil and hence it is contained in the non edible portion of the oil. The production of high quality esterquats from this by-product is challenging, but the invention describes a process to produce high quality esterquats having low odour and a low acid value. This enhances easy formulation of various products and better customer acceptance. Liquidesterquats produced from RBFA enable e.g. cold processing for fabric softener formulations. 酯季铵盐所获得的主要应用是作为织物柔软剂。在动物脂脂肪酸和棕榈油脂肪酸之后，来自于可持续源的脂肪酸例如米糠脂肪酸(RBFA)是期望的。RBFA是作为米糠油精制过程中的副产物而形成的，和因此它包含在所述油的不可食用部分中。由这种副产物来生产高品质酯季铵盐是挑战性的，但是本发明描述了一种生产具有低气味和低酸值的高品质酯季铵盐的方法。这增强了不同产物的易于配制性和更好的消费者接受度。由RBFA生产的液体酯季铵盐能够例如冷加工来用于织物柔软剂制剂。
