[0026] The formula of table 1 six laundry detergents

[0027]

[0028]

[0029] The steps of making laundry detergent are as follows:

[0030] Add the deionized water at 70°C into the chemical material tank, and then mix the sodium dodecylbenzenesulfonate, fatty alcohol polyether sodium sulfate, fatty alcohol polyoxyethylene ether, and coconut oil according to the formula ratio Amidopropyl amine oxide is added to it, and stirred evenly to obtain solution 1; when the temperature of solution 1 drops to 40-45°C, add the tetradecylmethyldihydroxyethylammonium bromide and sodium chloride according to the proportion ; When the temperature drops to 35°C, add sodium citrate, sodium hydroxide and essence according to the ratio. In this process, attention should be paid to accurate weighing and replenishment of evaporated water.

[0031] Take the preparation of formula 2 laundry detergent as an example: add 74.69kg of deionized water (at a temperature of 70°C) into the chemical ...

Abstract

The invention relates to an anion-cation compound antibacterial laundry detergent. The anion-cation compound antibacterial laundry detergent comprises, by weight, 1.0 to 9.6% of sodium dodecyl benzene sulfonate (LAS), 1.0 to 9.6% of sodium alcohol ether sulphate (AES), 1.0 to 8.0% of fatty alcohol polyoxyethylene ether, 1.0 to 8.0% of cocamidopropylamine oxide, 0.2 to 1.0% of bis(2-hydroxyethyl)methyltetradecylammonium bromide, 0.2% of sodium citrate, 0.01% of sodium hydroxide, 3.0% of sodium chloride and 0.1% of essence. The anion-cation compound antibacterial laundry detergent has good washing effect and substantial antibacterial effect.

Description

technical field [0001] The invention belongs to the field of detergent compositions, in particular to an anion-cation compound antibacterial laundry liquid. Background technique [0002] At this stage, laundry products have become a necessity of life. With the continuous improvement of people's consumption level, their demand is also increasing. The laundry product market has great development potential. Currently, the market is dominated by powdered laundry detergents and liquid laundry detergents. The preparation process of powder laundry detergent needs to add a large amount of additives, and the drying process of powder is more energy-intensive and has poor solubility. In contrast, laundry detergent does not have the above-mentioned disadvantages, and it has the advantages of good compoundability, complete dissolution, and no harm to skin and clothing. Therefore, more and more laundry users tend to use laundry detergent. [0003] Textiles are one of the ways for micro...
