Abstract

The invention provides a preparation method of a composite biological liquid detergent containing sodium p-toluenesulfonate. The method comprises the following steps: S1, preparing modified cellulosepowder; S2, preparing micro-porous starch; S3, weighing the modified cellulose powder, micro-porous starch, alkyl glycoside, sodium p-toluenesulfonate, sodium citrate, carboxymethyl cellulose, lipase,a perfume, ethanol and water according to corresponding weight parts; S4, heating the deionized water, and adding the micro-porous starch to obtain an aqueous micro-porous starch solution; S5, addingthe modified cellulose powder to ethanol to obtain an ethanol solution of the modified cellulose powder; and S6, adding the ethanol solution of the modified cellulose powder to the aqueous micro-porous starch solution, and performing mixing and uniform stirring to obtain the composite biological liquid detergent. The adsorption effect of the modified cellulose powder and the modified starch cooperates with the certain-strength mechanical stirring, temperature and rubbing effects in a washing process to accelerate the oil stain adsorption of starch and cellulose powder.

Description

technical field [0001] The invention relates to the field of daily chemical products, in particular to a preparation method of a compound biological detergent containing sodium p-toluenesulfonate. Background technique [0002] Dishwashing detergent is an indispensable daily necessities in life. With the continuous improvement of people's living standards and the continuous enhancement of health awareness, the requirements for detergents are becoming more and more stringent. However, although the detergents currently on the market still have some shortcomings, considering the various factors affecting dishwashing detergents, they have good washing ability, rich foam, minimal irritation to the skin, and good biodegradation Sex, which is just in line with the general trend of detergent development. Liquid dirt is mostly oil-soluble, and general liquid dirt (such as fatty acids, animal and vegetable oils) can undergo saponification with lye. Generally, it is the effect of surf...
