Problems solved by technology

However, when people use liquid detergent, if the viscosity of the detergent is too low, the fluidity is high, and it is not easy to control the amount when pouring, which will cause waste; and if the viscosity of the detergent is too high, the fluidity is low, and the detergent is easy to remain in the container. The wall and the bottom cannot be completely poured out, and if they are not used up, it will also cause waste

Embodiment

[0124] The following examples are for illustration and comparison of the present invention and are not intended to limit the present invention.

[0125] The components shown in Tables 1 to 9 were mixed to obtain the liquid detergent compositions of Examples and Comparative Examples. Each of the following evaluations was performed using each obtained composition. The results are shown in Tables 1-9.

[0126] (1) Evaluation of antibacterial properties

[0127]Using the QB / T 2738-2012 evaluation method for the antibacterial effect of daily chemical products, according to the ratio of 1:100, use sterile hard water (weigh 0.034g anhydrous calcium chloride, 0.139g magnesium chloride hexahydrate, add 1L of distilled water, and pass through 121 ℃ pressure steam sterilization 20min) to dilute each liquid detergent composition (test sample). Take 5ml of diluted diluted samples and inject them into sterile test tubes respectively, add 0.1ml of each bacterial solution 1 to 4, and after...

Abstract

Provided is an antibacterial liquid detergent composition for clothes, having a pH of 8.5-10 at 25 DEG C, and comprising the following components (a) to (d): (a) a cationic surfactant, (b) an anionicsurfactant, (c) an alkali agent having a pKa of 7.5-11, and (d) water. The content of component (b) is 7.0% or less by mass, the mass ratio (b) / [(a)+(b)] of component (b) to the total of component (a)and component (b) is 0.75 or less, and the content of polyoxyalkylene alkyl ether sulfate (b1) in the anionic surfactant is at least 80.0% by mass. This antibacterial liquid detergent composition forclothes does not require a special separate antibacterial substance, has an excellent antibacterial effect even if the cationic surfactant content is low, and enables favorable fluidity and foaming properties to be obtained.

Description

technical field [0001] The invention relates to an antibacterial liquid detergent composition for clothes. Background technique [0002] In the washing of clothes, there is an increasing demand for antibacterial properties. [0003] At present, almost all antibacterial detergents are combinations of cationic surfactants, anionic surfactants and / or nonionic surfactants. If there is no anionic surfactant, the foaming performance is poor, but when anionic surfactant and cationic surfactant are used together, the antibacterial effect of cationic groups will be weakened. Therefore, in order to achieve antibacterial purposes, a large amount of cationic surfactants must be combined. However, when the concentration of the cationic surfactant is too high, problems such as poor stability of the system, easy precipitation, and poor recontamination prevention performance arise. [0004] Therefore, a detergent is proposed in Patent Document 1, which achieves an antibacterial effect by...
