Embodiment 1～8

[0043] See Table 1 and Table 2.

[0044] Table 1

[0045]

[0046]

[0047] The quaternary ammonium salt active material is ethyl dipalmitate hydroxyethyl methyl methyl sulfate;

[0048] The thickener is: acrylamide / acryloyloxyethyl trimethylammonium 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 raw material ratio in Table 1, the softener composition was formulated according to the method well known to those skilled in the art.

Embodiment 9-13

[0064] This embodiment is a softener composition, and the raw material ratio is the same as that of Example 5, except 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 the 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] In the process of repeated use and repeated washing of the fabric, according to different materials and weaving processes, the fibers in the fabric, especially the fine fibers, tend to be entangled, entangled, and even break and fall off. Affect the appearance of the fabric, make the fabric hard and rough, and affect 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 supple. [0003] The raw materials of fabric softeners 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 be used for fabric softening. Its representative products are double eighteen. Alkyl dimethyl ammonium chloride (D1821), alkyl ...
