  • Patent number: 11773347
    Abstract: 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. Liquid esterquats produced from RBFA enable e.g. cold processing for fabric softener formulations.
