Problems solved by technology

However, its stability does not involve the impact of the polymer on the physical and chemical state of the detergent, and the ternary polymer process of ethylene glycol, 1,3-propanediol, and methyl terephthalate is relatively complicated, and its stability test The results still show that the degree of hydrolysis of polyester polyether polymer after heat storage is greater than 42%, that is, there is a very high risk of hydrolysis
[0005] To sum up, it is desirable to add polyester soil-removing polymers to detergents to improve the detergency of detergents and prevent dirt re-staining. However, at this stage, in alkaline environments, the polyester block Hydrolysis is inevitable, which will greatly shorten the shelf life of the product

preparation example Construction

[0150] The present invention contains the liquid detergent composition preparation method of stable polyester decontamination polymer, comprises the following steps:

[0151] 1) Add a part of deionized water and alkali to the configuration tank;

[0152] 2) Start stirring, heat up to 60°C, heat and saponify fatty acids into fatty acid salts under alkaline conditions, and stir until completely dissolved;

[0153] 3) sequentially add anionic surfactant, nonionic surfactant and amphoteric surfactant, and stir until completely dissolved;

[0154] 4) Stop heating, add the remaining amount of deionized water to the configuration tank, and cool down to below 40°C;

[0155] 5) adjust the pH;

[0156] 6) Add additives such as preservatives and stir until completely dissolved;

[0157] 7) adjust the viscosity;

[0158] 8) Add the polyester soil release polymer and stir evenly, wherein the weight percentage of the polyester soil release polymer in the liquid detergent composition is ...

Abstract

The invention relates to a stable liquid detergent composition containing a polyester decontaminating polymer and a preparation method thereof. The liquid detergent composition is prepared from the component in percentage by weight: 0.01 to 10 percent of one or more polyester decontaminating polymer, wherein the viscosity of the liquid detergent composition is 10 to 15000cst at 25 DEG C, a pH value is 5.0 to 10, and a heat reservoir viscosity change ratio is less than 25 percent. The polyester decontaminating polymer can stably exist under an alkali liquid detergent environment for a long time, and can be matched with surfactant in liquid detergent so as to play the good decontamination effect.

Description

technical field [0001] The invention relates to the technical field of detergents, in particular to a stable liquid detergent composition containing polyester soil release polymer and a preparation method thereof. Background technique [0002] Household fabric detergents are mainly surfactants, supplemented by specific functional auxiliaries. Adding specific polymers and enzymes can remove specific stains more efficiently, thereby reducing the amount of surfactant used, which is especially powerful for concentrated products. Detergent compositions formulated with polyester soil release polymers (SRP) generally have excellent detergency on greasy and granular soils, and the detergency is significantly better than that of detergent compositions with higher surfactant content. [0003] Common soil release polymers are polyacrylic acid, polyether modified polyethyleneimine (EPEI), polyester polyether, etc. During the washing process, the polyester decontamination polymer adsor...
