Embodiment 1～8

[0043] See Table 1 and Table 2.

[0044] Table 1

[0045]

[0046]

[0047] The quaternary ammonium salt active substance is ethyl palmitate hydroxyethyl methylsulfate amine;

[0048] The thickener is: acrylamide / acryloxyethyltrimethylammonium chloride copolymer;

[0049] The cationic starch is starch hydroxypropyltrimethylammonium chloride. The specific parameters are shown in Table 2.

[0050] Table 2

[0051]

[0052] According to the ratio of raw materials in Table 1, the softener composition was prepared by methods well known to those skilled in the art.

Embodiment 9-13

[0064] This embodiment is a softener composition, the ratio of raw materials is the same as that of embodiment 5, the difference is that the quaternary ammonium salt active substance used is different. See Table 4 for details.

[0065] Table 4

[0066]

[0067] The cationic starch is starch hydroxypropyltrimethylammonium chloride. The degree of substitution is 0.25, the viscosity of 20wt% aqueous solution is 200mPa·s, and the amylose content is 25wt%;

Abstract

The invention relates to a softener compound which comprises the following components by weight percent: 3-7% of quaternary ammonium salt active matter, 0.02-0.5% of cationic starch, 0.01-0.5% of thickening agent, 0-2% of additive and the balance of water, wherein the cationic starch is prepared from starch and 2,3-glycidyl trimethyl ammonium chloride, 3-chlorine-2-hydroxypropyl trimethyl ammonium chloride, 3-chlorine-2-hydroxypropyl dimethyl-dodecyl ammonium chloride or 3-chlorine-2-hydroxypropyl dimethyl-octadecyl ammonium chloride. The softener compound is formed by compounding cationic starch with quaternary ammonium salt active matter; less cationic starch (accounting for 0.02-0.5wt% of the compound) is used together with quaternary ammonium salt; the softening fabric effect is better than that of singly used quaternary ammonium salt; the oily hand feel caused by the quaternary ammonium salt in higher saturability is relieved to some extent; a smoother experience is brought.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a softener composition. Background technique [0002] During the repeated use and repeated washing of fabrics, the fibers in the fabrics, especially the fine fibers, tend to be entangled and entangled with each other, and even break and fall off according to different materials and textile processes. It affects the appearance of the fabric, makes the fabric hard and rough, and affects the overall feel. Fabric softener can form a cationic protective film on the surface of fabric fibers to reduce fiber friction and make clothes soft and soft. [0003] The raw materials of fabric softener are mainly quaternary ammonium salt cationic surfactants. There are many cationic products of this type, but the quaternary ammonium salt products with double long-chain groups can really be used for fabric softening. The representative products are such as double 18 Alkyl dimethyl ammoni...
