Abstract
The invention relates to compositions comprising a peroxyacid bleach precursor, a peroxide source, at least about 15% by weight of a carbonate source, which may comprise the hydrogen peroxide source or part thereof, and at least about 7% by weight of an organic carboxylic acid whereby a 1% solution of the composition in demineralised water provides a pH from 8.8 to 9.9. The compositions are useful to provide sanitization of fabrics, in particular to reduce the activity of certain bacteria groups.
Claims20
A laundry or dishwashing detergent composition comprising a bleach system which contains a hydrogen peroxide source and at least about 2.5% by weight of at least two peroxyacid bleach precursors, wherein one of said peroxyacid bleach precursors is TAED and the second peroxyacid bleach precursor is NOBS, DOBS or NACA-OBS, at least about 15% by weight of a carbonate source, wherein said carbonate source may include said hydrogen peroxide source, at least about 7% by weight of an acid, whereby a 1% by weight mixture of said composition in demineralised water provides a pH from about 8.8 to 9.9.
A method for washing textiles in a washing machine said method comprising,
- (A) providing a composition, said composition comprising, a bleach system which contains a hydrogen peroxide source and at least about 2.5% by weight of a peroxyacid bleach precursor, at least about 15% by weight of a carbonate source, wherein said carbonate source may include said hydrogen peroxide source, at least about 7% by weight of an acid, whereby a 1% by weight mixture of said composition in demineralised water provides a pH from about 8.8 to 9.9;
- (B) introducing said composition into a dispensing device;
- (C) introducing said dispensing device into the drum of a washing machine;
- and
- (D) adding wash water into said washing machine.
