Reaction of Hydrogen per Oxide Killer
Catalase
Enzyme is also known as (Highly Concentrated Hydrogen Peroxide Killer Enzyme).
Catalase is
highly effective in catalyzing the decomposition of hydrogen peroxide into
oxygen and water. In textiles processing, this is often the most preferred mode
of hydrogen per oxide removal after bleaching and break down products are
totally inert to reactive dyestuff. This enzyme accommodates broad range of pH
as well as temperature and remains effective even at high concentration of
hydrogen peroxide.

Reactive dye.
Catalase
removes hydrogen per oxide in very simple way. It is cost effective and
reliable. Excess reducing agent can damage the fabric and also effect dyeing.
Less amount of reducing agent will not remove Hydrogen per oxide properly and
will affect dyeing process again.
