Abstract

The invention provides a preparation method of a handwash tableware detergent containing sodium xylene sulfonate. The preparation method comprises the following steps that S1, insoluble rice bran particles are prepared; S2, alkaline hargil is prepared; S3, an alkaline hargil / chitosan compound is prepared; S4, the following ingredients: the insoluble rice bran particles, the alkaline hargil / chitosan compound, sodium dodecyl benzene sulfonate, sodium xylene sulfonate, alpha-olefin sulfonate, sodium chloride and deionized water are weighed in parts by weight; and S5, the deionized water is heatedin water bathing, sodium dodecyl benzene sulfonate, sodium xylene sulfonate and alpha-olefin sulfonate are sequentially added and stirred till to be completed dissolved, then the insoluble rice branparticles and the alkaline hargil / chitosan compound are added and stirred till to be dispersed evenly, the pH value of the solution is conditioned to be neutral, finally sodium chloride is added to condition the viscosity of the solution, and the handwash tableware detergent is obtained. The detergent contains less surface active agent, can reduce water pollution and has the good deoiling and stain removing effects.

Description

technical field [0001] The invention relates to the field of daily chemical products, in particular to a preparation method of a hand dishwashing detergent containing sodium xylene sulfonate. Background technique [0002] Dishwashing detergent is an indispensable household cleaning product in people's daily life. In recent years, dishwashing detergent products have developed rapidly, and there are more and more prominent problems in dishwashing detergents on the market. With the improvement of people's living standards and the gradual enhancement of environmental protection awareness, people pay more and more attention to their own health and safety issues, and the requirements for detergents are becoming more and more stringent. Dishwashing detergent should not only have good detergency and economy, but also be environmentally friendly and mild. At present, most of the tableware is difficult to clean due to grease, and a large amount of surfactant is needed to remove the ...
