What type of enzyme is suitable to wash for a medium light and light colored denim pants, why?
The enzyme acid used to wash wash denim has this requirement because the Acid Acid fades faster than the Neutral enzyme.

42. The role of common chemicals in wash formula ANTISTAIN, DETERGENT, AND POTASSIUM PER MANGANATE, MICRO EMULSION SOFTENER, HYDROGEN PEROXIDE, OPTICAL BRIGHTENER and DESIZING AGENT.

ANTISTAIN (ANTISTAIN): To help prevent the white weft and the bag lining from becoming stained again by adhering to the dyed dye in the wash tank.
Absorbent or surfactant (DETERGENT): To remove dirt, oil, minerals on the surface and in the fabric, helping clothes absorb chemicals more effectively.
Violet (POTASSIUM PER MANGANATE): After desizing, it is sprayed onto a region of ssos on the pants to remove the color of indigo, create a fading effect and be removed during Enzyme wash.
Soft lake (MICRO EMULSION SOFTENER): Create good softness for clothes.
Oxygen remover (HYDROGEN PEROXIDE): Bleach for clothes that are brighter.
OPTICAL BRIGHTENER: Turn on the whiteness after bleaching.
Desizing agent (DESIZING AGENT): Remove the pit on the surface of clothes before washing.
