Abstract: The present invention relates to a machine dishwashing composition comprisingfrom 1% to 80% by weight of detergent builder compoundoxygen-releasing bleaching agentfrom 0.05% to 2.5% by weight, preferably 0.1% to 1% by weight of paraffin oil,nitrogen-containing corrosion inhibitor compoundMost preferably the oxygen-releasing bleaching agent is incorporated such that the level of available oxygen measured according to the method herein is from 0.3 to 1.7, preferably 0.5 to 1.

Abstract: The present invention relates to a detergent composition containing from 1% to 80% by weight of a detergent builder compound; from 0.005% to 2,5% by weight of a paraffin oil; an oxygen-releasing bleaching agent such that the level of available oxygen in the composition measured according to the method herein is from 0.3% to 2.5% wherein the rate of release of said available oxygen is such that the available oxygen is completely released from the composition in a time interval of from 3.5 minutes to 10.0 minutes, using the test protocol described in the present description.

Abstract: There is provided a particulate solid machine dishwashing detergent composition containing alkali metal percarbonate bleach coated with a mixed salt comprising an alkali metal carbonate and an alkali metal sulphate salt; a peroxyacid bleach precursor; an acidification agent; and a means for enabling delayed release of said acidification agent such that the pH of said composition as a 1% solution in water at 20.degree. C. is from 9.5 to 13.0 prior to release of said acidification agent, and such that the pH of said composition as a 1% solution in water at 20.degree. C. is from 9.3 to 7.0 subsequent to complete release of said acidification agent.

Abstract: There is provided a bleaching composition, suitable for use in a machine dishwashing method, containing: an oxygen-releasing bleaching agent, from 0.05% to 2.5% by weight, preferably 0.1% to 0.6% by weight of a paraffin oil, from 0.005% to 3%, preferably 0.02% to 1% and most preferably from 0.05% to 0.5% of a benzotriazole compound. Preferably the bleaching composition forms a part of a detergent composition.

Abstract: There is provided a bleaching composition containing (a) an oxygen-releasing bleaching agent as a source of available oxygen and (b) a non-paraffin oil organic silver coating agent. In one aspect the rate of release of available oxygen is carefully controlled such that the available oxygen is completely released from the composition in a time interval of from 3.5 minutes to 10.0 minutes. In another aspect the composition contains (c) an additional corrosion inhibitor compound.

Abstract: The present invention relates to a machine dishwashing composition containingfrom 1% to 80% of a detergent builder component other than carbonatefrom 0% to 9%, preferably 0% to 5%, most preferred 0% of alkali-metal carbonate or bicarbonate saltan oxygen-releasing bleaching agent such that the level of available oxygen measured according to the method herein is from 0.3 to 1.7, preferably 0.5 to 1.2,from 0.05% to 2.5%, preferably 0.1% to 0.6% of a paraffin oil, the rate of release of oxygen being preferably also controlled; the present invention also encompasses a process for making such compositions.
