Sodium carbonate peroxyhydrate - commonly referred to as sodium percarbonate - is an addition compound of sodium carbonate and hydrogen peroxide.

OXYPER® S, is a coated and stabilised sodium percarbonate. It combines the dual properties of sodium carbonate and hydrogen peroxide to deliver significant benefits in powder or tablet detergent applications such as cleaning, whitening, stain removal, hygiene, disinfection, water softening and product compaction.

The combination of 'two functions in one' product, in addition to a high available oxygen content and high bulk density, allows OXYPER® S to improve detergency performance while reducing the need for additional builders and consequently the environmental impact of the formulated detergents.

OXYPER® S has minimal impact on the environment, decomposing after use into water, oxygen and soda ash.

OXYPER® S is mainly used in laundry powder, automatic dish washing tablet or bleach & laundry additives but can also be used in other applications where a solid, easy to use source of alkaline hydrogen peroxide is needed such as water treatment, soil remediation, textile bleaching…
