  • Publication number: 20240034962
    Abstract: The present invention concerns a granule comprising Mn(II) oxalate, a protonated salt of a cyclic triamine, a polysaccharide absorbent and a coating agent. In another embodiment the invention concerns a granule comprising a polysaccharide absorbent, a protonated salt of a cyclic triamine and no or very small amounts of Mn. The invention also concerns methods of preparing said granules comprising Mn(II) oxalate, polysaccharide absorbent and such salts or comprising polysaccharide absorbent, such salts and no Mn compound and bleaching formulations comprising the granules and a peroxy compound or a precursor thereof. Granules comprising Mn(II) oxalate, polysaccharide absorbent and the salt or comprising polysaccharide absorbent, the salt and no Mn compound, and formulations comprising these are suitable for use in catalysing oxidation, for example as a component of a dishwasher bleaching composition. The invention further relates to methods of oxidising with the bleaching formulations described herein.

  • Publication number: 20230416658
    Abstract: The present invention concerns a composition comprising Mn(II) acetate, a protonated salt of a cyclic triamine, a polysaccharide absorbent, and a water-soluble polymer, e.g. polyvinylalcohol. The invention also concerns a method of making such compositions, preferably in the form of a granule, and bleaching formulations comprising the salt and a peroxy compound or precursor thereof. The protonated ligand salt and Mn(II) acetate containing composition and formulations comprising it, are suitable for use in catalysing oxidation, for example as a component of a laundry or dishwasher bleaching composition. The invention further relates to cleaning agents comprising the compositions described herein.
