1. The solubility is rapidly dissolved in water, and the laundry detergent with qualified quality acts on clothes evenly; Products that are difficult to dissolve in water or need to be stirred for a long time and only have a local cleaning effect are products with poor quality.

2. Phosphorus-free means environmental protection and safety.

You may have heard of "water eutrophication". Take a fish pond as an example. If "water eutrophication" occurs, firstly, microorganisms such as algae in the fish pond will multiply in large numbers, then the oxygen in the water will be greatly reduced, and then the fish and shrimp will die of lack of oxygen ... The whole fish pond is ecologically unbalanced and finally becomes a stagnant pool. In this process, "phosphorus" is equivalent to a nutrient that stimulates the growth of microorganisms, which is extremely harmful to the environment.

In addition, phosphorus can also affect the absorption of calcium by human body, causing rickets and the like. Don't use phosphorus-containing washing powder because it is not easy to remove phosphorus from clothes during rinsing-for health, you need to rinse with more water and more time.

3. The clothes with fluorescent whitening agent look as bright as new, but the fluorescent whitening agent only makes the clothes look clean optically, but in fact the stains still exist.

4. Clothes washed with laundry detergent will not turn yellow when they are taken out the next year.
