Granular concentrated detergent composition

Abstract

The invention discloses a granular concentrated detergent composition, which relates to the technical field of daily chemical washing products. The composition comprises the following components in percentage by mass: 25%-70% of an anionic surfactant; 5%-30% of a nonionic surfactant; 5%-40% of hydrophilic silicon dioxide; 0.5%-15% of a washing auxiliary agent; and 0.01%-20% of water; wherein the total content of the anionic surfactant and the nonionic surfactant is greater than 45%. The technical scheme provided by the invention is adopted, all the components are synergistically compounded, the concentrated granular detergent composition having good formability, fluidity, and solubility, while also having unexpected excellent properties in terms of ash content and redeposition resistance can be obtained, which can simultaneously solve the problems of particle formability, fluidity, and solubility(especially solubility under adverse conditions such as low temperature or high hardness water), and has an industrial value.

Description

technical field [0001] The invention relates to the technical field of daily chemical cleaning products, in particular to a granular concentrated detergent composition. Background technique [0002] The main advantage of concentrated detergent products is to reduce the use of non-functional raw materials and packaging, and reduce transportation costs. Whether it is concentrated laundry detergent or concentrated laundry powder, it not only saves energy consumption, reduces the impact on the environment, but also saves costs , serve multiple purposes, thus promoting the concentration of detergents is an inevitable trend in the development of the industry. [0003] There are two production processes of domestic concentrated washing powder. The first process is agglomeration forming method, which has the advantage of energy saving, and the product must be high in weight, but there are problems such as narrow selection of surfactants and slightly poor solubility; the second proce...

AI Technical Summary

Problems solved by technology

[0003] There are two production processes of domestic concentrated washing powder. The first process is agglomeration forming method, which has the advantage of energy saving, and the product must be high in weight, but there are problems such as narrow selection of surfactants and slightly poor solubility; the second process It is a composite process of spraying base powder for high towers and then compounding other additives and surfactants. It is characterized by a wide range of surfactants and good solubility of the product. The disadvantage is that the amount of liquid added in the compounding is limited. When adding 40% of the solid raw materials in the mix, the apparent density of the final product is difficult to reach 600g / L

In addition, the total active substance content of concentrated washing powder is generally less than 30%, and a large amount of fillers and alkaline additives are required, such as sodium sulfate, zeolite, soda ash, saponin, caustic soda, etc. However, zeolite and soda ash A high dosage will bring obvious ash deposition, a high dosage of alkaline additives will cause great damage to fabric fibers, and it will be very irritating to the skin when washing by hand

Although the content of active substances in concentrated laundry detergent can reach more than 45%, the concentration of surfactant in it is too high, which will affect the fluidity and stability of the product. When dispersed in water, gel phenomenon may occur, resulting in slow dissolution. Thereby reducing the efficacy and ease of use of the product
