[0029] One. Embodiment and comparative example

[0030] According to the composition of following table 2 composition preparation soap, preparation steps are as follows:

[0031] (1) Add soap granules to the stirring pot and stir evenly;

[0032] (2) Add the cationic polymer and deionized water after mixing in 1:1, and stir evenly;

[0033] (3) add metal ion chelating agent, pigment, stir;

[0034] (4) Add spices and antioxidants at last, stir well and let stand;

[0035] (5) The stirred product obtained in the previous step passes through a refiner and a three-roll mill successively, and finally is vac...

Abstract

The invention discloses a washing soap containing a cationic polymer. The washing soap is prepared from the following raw material components in percentage by weight: 85-98% of soap grains, 0.2-3.0% of the cationic polymer, 0.5-4.0% of deionized water and 0.5-8.0% of an auxiliary agent. The soap grains are fatty acid salts which are prepared by neutralizing and saponifying fatty acid prepared from one or more than two of beef and mutton fat, lard oil, palm oil, palm kernel oil and coconut oil and are suitable for soap production; the cationic polymer comprises repetitive units with the following structure: R and R' are alkyl with the carbon atom number of 1-3, X-is CH3SO4-, CH3CH2SO4- or halide ions, the percentage of the molecular weight of the repetitive units in the total molecular weight of the cationic polymer is greater than 70, and the weight-average molecular weight of the cationic polymer is 2000-400000. The problem that the washing soap is easy to cause fading of clothes can be solved.

Description

technical field [0001] The invention relates to the field of daily chemical industry, in particular to a cationic polymer-containing laundry soap and a production method thereof. Background technique [0002] Laundry soap is generally used for hand washing of clothes. In the process of hand washing, it is easy to cause the color of clothes to fade, especially direct dyes that are easier to lose color. Chinese patent CN102933700B discloses a cationic polymer-containing cleaning soap and its preparation method. Compared with ordinary cleaning soaps, it has a significant improvement in coating resistance and anti-gelatinization. The effect of dye cross-dyeing other clothing after color fading, yet its effect on color protection is only limited to preventing dye cross-dyeing other clothing after clothing fading, does not solve the problem of clothing itself fading. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present ...
