  • Publication number: 20100317557
    Abstract: Non-oxidiser particles containing sodium percarbonate and at least one additive, the amount of constituents other than sodium percarbonate in the particles being such that the particles are classified as non-oxidiser according to the standard test method O.1 of the UN Manual of Tests and Criteria, sub-section 34.4.1 and that the particles have an available oxygen content of below 12% by weight, wherein the sodium percarbonate is coated and/or co-granulated with the additive(s). Blends comprising such particles. Process for the production of these particles and blends. Use of these particles or blends in detergent compositions and detergent compositions containing them.
