Process for the preparation of fabric softeners actives and products that are used.

摘要

The invention relates to a method of preparing a biodegradable active agent, fabric softener. Said process comprises the following steps: a) providing a source of triglyceride and reacting said source to form a mixture, comprising FATTY ACIDS FORMULA R 1 CO 2 H, fatty acid esters of the formula R 1 CO 2 R '' '' O mixtures thereof; WHERE R 1 IS ALQ Uilo C 1 - C 22, alkenyl C 2 - C 22, and mixtures thereof; R '' is alkyl C 1 - C 4 hydroxyalkyl MONO C 2 - C 4 dihydroxyalkyl C 3 - C 4; B) RACCIONAR MIXTURE OF PHASE (A) with one or more amines of formula (I), wherein R is alkyl C 1 - C SUB, 6 hydroxyalkyl C 1 - C 6, benzyl or mixtures thereof; Each Z INDEPENDENTLY SELECTED FROM A GROUP CONSISTING - OH, - CHR''OH, - CH (OH) CH 2 OH, NH 2 and mixtures thereof, wherein R '' is C 1 -C 4; M is an integer of 1 to 3; N is an integer of 1 to 4; To form a precursor agent blend fabric softener of formula (II), wherein R, R 1, m and n are the same as defined above; YC) quaternizing said mixture harbinger of step (b) by reacting it with an agent quaternizing OF FORMULA RX, where R is the same as defined in step (B) YX is a compatible anion softener, FORMING AN ACTIVE AGENT SOFTENER TISSUE OF FORMULA (VII), wherein R, R 1, X, Y, m and n are the same as defined Anteri ously; Provided that at least step (C) DEVELOP IN THE PRESENCE OF a chelating agent selected from the group consisting of diethylenetriaminepentaacetic acid, ethylenediamine - N, N 'disuccinic acid and mixtures thereof. SE also provides a method of forming a fabric softener premix AND A fabric softening composition, AND PRODUCTS USED FOR THE THREE STAGES.
