Product Description

Sodium Perborate is manufactured by reaction of sodium tetraborate, hydrogen peroxide, and sodium hydroxide. Sodium perborate tetrahydrate is an important ingredient of manyhousehold laundry detergent powders, laundry bleach additive products and automatic machine dishwash powders. Unlike sodium percarbonate and sodium perphosphate,perborate is not just an addition compound of peroxide, but contains true peroxygen bonds, Sodium perborate tetrahydrate has good storage stability when blended with many ingredients of formulated products for use in temperate climates.
