A bleach catalyst suitable for use in automatic dishwashing comprising a mixed metal oxide.
First claim
Opening claim text (preview).
The invention claimed is: 1. An automatic dishwashing composition comprising: a heterogenous bleach catalyst comprising copper oxide on a zirconium oxide carrier, and wherein the heterogeneous bleach catalyst has been acid treated; and one or more of a bleaching agent, a builder, and a bleach activator. 2. The automatic dishwashing composition according to claim 1 , wherein the copper oxide of the heterogenous bleach catalyst is present in an amount from 1 to 50 mol % relative to the zirconium oxide carrier. 3. The automatic dishwashing composition according to claim 1 , wherein the copper surface area of the copper oxide of the heterogenous bleach catalyst is less than 1 m 2 /g. 4. The automatic dishwashing composition according to claim 1 , wherein the heterogenous bleach catalyst has been calcined. 5. The automatic dishwashing composition according to claim 1 , wherein the copper oxide of the heterogenous bleach catalyst is present in an amount from 2 to 20 mol % relative to the zirconium oxide carrier. 6. A method of making the automatic dishwashing composition of claim 1 , the method comprising: mixing the heterogeneous bleach catalyst with one or more of a bleaching agent, a builder, and a bleach activator. 7. The method according to claim 6 , wherein the copper oxide of the heterogenous bleach catalyst is present in an amount from 1 to 50 mol % relative to the zirconium oxide carrier. 8. The method according to claim 6 , wherein the copper surface area of the copper oxide of the heterogenous bleach catalyst is greater than zero. 9. The method according to claim 6 , wherein the copper surface area of the copper oxide of the heterogenous bleach catalyst is greater than 0.01 m 2 /g and less than 4 m 2 /g.
