Application

It can effectively remove stains, especially grease and dirt.

It softens water and can be combined with calcium and magnesium ions in the water to reduce the adverse effect of hard water.

Its ability of dispersion and suspension help to disperse dirt in the washing liquid and prevent it from redepositing on the clothing.

It plays a certain role in regulating the pH of the washing liquid and optimizing the washing environment.

It is used with other detergent ingredients to improve the overall washing performance.In some applications, due to their different properties in nature, there may be different applicable scenarios.

For example, in some occasions with high drying requirements or rapid dissolution, sodium metasilicate pentahydrate may be more inclined to be used;

In the case of higher hygroscopic and stability requirements, sodium metasilicate anhydrous may be selected.
