Catalase can catalyse the decomposition of hydrogen peroxide into water and molecular oxygen.
It’s used to remove residual hydrogen peroxide in applications where hydrogen peroxide is added e.g. for pasteurization or bleaching. It act on hydrogen peroxide only, and doesn’t react with dye. Thus, it has been suggested to use catalase in the textile industry for the removal of hydrogen peroxide from fabric which is bleached by an alkaline hydrogen peroxide treatment before dyeing.

Safety
Enzyme preparations belong to protein, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor
