preparation example Construction

[0093] A method for preparing a liquid detergent composition, comprising the steps of:

[0094] 1) Put water into the batching pot first;

[0095] 2) Under stirring, slowly add the thickener, and after fully dispersed, adjust the pH to 5-9;

[0096] 3) Add component A, component B, and surfactant in sequence, and stir evenly;

[0097] 4) Put the essence and enzyme preparation into the batching pot and stir evenly;

[0098] 5) Add other additives into the batching pot and stir evenly;

[0099] 6) Pass the inspection and pack.

[0100] 250ppm hard water was used in the experiment to prepare according to the method of GB 9985-2000 B1.2.

[0101] Determination of anti-scaling performance:

[0102] Measuring principle: Use an electric heating rod to heat the scaling of different sample products in hard water.

[0103] Into the beaker, add 1.0L 250ppm hard water, and 8g sample, stir to dissolve, put into the electric heating rod, turn on the electricity to heat. When the wate...

Embodiment

[0139] The compositions of Comparative Examples 1-2 and Examples 1-3 were formulated according to Table 1.

[0140] The composition of the domestic automatic dishwasher detergent composition of table 1 embodiment 1-3

[0141]

[0142]

[0143] 1. Purchased from BASF; 2. Purchased from Lubrizol.

[0144] The pH measurement results show that the pH of Comparative Examples 1 to 4 is strongly alkaline after being diluted with pure water according to 1% mass ratio, and the anti-scaling performance test experiment also shows that the calcium ion content is as high as 331.8mg, 248.2mg, 108.3mg, and 80.4mg, that is, there is obvious calcium scale deposition. However, the pH of the 1% dilutions of Examples 1 to 3 is all within the pH7 to 8 range, which is a neutral and mild detergent, and the anti-scaling performance test shows that the calcium ion content is less than 10 mg, and there is no visible calcium scale on the heating tube. deposits, so heating tubes and shiny dishes ...

Abstract

The invention relates to a liquid detergent composition as well as a preparation method and application thereof. The pH (potential of Hydrogen) of the liquid detergent composition is 5 to 9; the liquid detergent composition is prepared from the following components in percentage by weight: (i) 0.01 percent to 5 percent of a thickener; (ii) 0.1 percent to 70 percent of a component A; (iii) 0.1 percent to 10 percent of a component B; (iv) 0.01 percent to 10.00 percent of a surfactant; (v) 0.01 percent to 10 percent of an enzymic preparation; (vi) 20 to 99 percent of water. The composition provided by the invention has the neutral pH and remarkable water scales are not generated after the detergent composition is used for a dish washing machine for a long period; remarkable damages to the dish washing machine are not caused and the brightness of washed tableware is also not influenced; meanwhile, the liquid detergent composition has strong cleaning power.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a liquid detergent composition and its preparation method and application. Background technique [0002] The emergence of dishwashers can meet consumers' high-level needs for healthy life and leisure time, and is more suitable for the high-paced life of modern families. In terms of working principle, the dishwasher cleans and decontaminates the tableware mainly by virtue of the spray effect generated by the strong water flow in the three-dimensional space, the thermal energy effect of the heated water, and the degreasing and decontaminating effect of the detergent. In order to improve the cleaning power of the dishwasher, it is necessary to use detergent in combination, and powder and block dosage forms are well known in the industry. Generally, powder and block products use phosphorus-containing additives, strong alkaline additives, and strong oxidizing agents. ...
