Detergent Composition
A detergent composition comprising an enzyme and a bleaching compound and comprising two or more distinct regions, wherein the enzyme is located in a first distinct region and the bleaching compound is located in a second distinct region and further wherein a builder comprising an amino acid based compound and/or succinate based compound is located in the first distinct region. The compositions exhibit improved stability of the enzyme.
1 . A detergent composition comprising:
an enzyme;
a bleaching compound; and
a builder comprising an amino acid based compound,
wherein the detergent composition comprises two or more distinct regions,
wherein at least one distinct region is a solid and at least one distinct region is a gel or paste,
wherein the enzyme and the builder are located in a first distinct region, the bleaching compound is located in a second distinct region,
wherein the first distinct region is substantially free of bleaching compound,
wherein the second distinct region is substantially free of builder,
wherein the detergent composition is a unit dose detergent composition, and
wherein the first distinct region contacts the second distinct region.
2 . The detergent composition according to claim 1 , wherein the enzyme comprises a protease.
3 . The detergent composition according to claim 1 , wherein the amino acid based compound comprises methyl-glycine-diacetic acid, and salts and derivatives thereof and/or glutamic-N,N-diacetic acid and salts and derivatives thereof.
4 . The detergent composition according to claim 1 , wherein the bleaching compound is selected from inorganic peroxides or organic peracids and mixtures thereof.
5 . The detergent composition according to claim 4 , wherein the inorganic peroxide is selected from the group consisting of percarbonates, perborates and persulphates and their salts.
6 . The detergent composition according to claim 1 , wherein the first distinct region comprises 10% wt or less of the total amount of bleaching compound in the detergent composition.
7 . The detergent composition according to claim 6 , wherein the first distinct region is free of bleaching compound.
8 . The detergent composition according to claim 1 , wherein the second distinct region comprises 10% wt or less of the total amount of enzyme in the detergent composition.
9 . The detergent composition according to claim 8 , wherein the second distinct region is substantially free of enzyme.
