A kind of washing liquid and preparation method thereof

technical field

The invention relates to a laundry detergent and a preparation method thereof, which are mainly used for cleaning and washing of family personal clothes, bed sheets, quilt covers, hotels, hotel bed sheets, quilt covers and other fabrics.

Background technique

Soap and washing powder have been used as traditional fabric washing and cleaning products for decades. They play an important role in people's daily life and their historical value is beyond reproach. The washed seeds need to be soaked and dissolved in water first, which brings additional troubles to the washing process. At the same time, some traditional soaps and washing powders are all lumpy and powdery solids, and a large amount of solid fillers need to be added during the molding process. , most of these fillers play a molding role, which is meaningless to the washing effect itself, increases the cost and wastes a lot of material resources, and most of the fillers are phosphorus-containing minerals, which cause harm to the environment that human beings depend on for survival. Adverse effects are out of rhythm with the energy-saving and environment-friendly society pursued by modern people.
