Abstract

A detergent composition comprising; a subtilisin variant having the amino acid sequence set forth in SEQ ID NO 1, and at least one additional ingredient selected from; i) bleaches selected from percarbonates, persulphates and organic peracids, ii) aminocarboxylates, or iii) sulphonated polymers, or iv) organophosphoric acids or salts thereof and mixtures thereof is provided. Also provided is a detergent composition comprising a subtilisin variant having the amino acid sequence set forth in SEQ ID NO 1, wherein, the detergent composition is at least partially enveloped in a water soluble or water dispersible package. The compositions exhibit good performance on proteinaceous stains, even when formulated at alkaline pHs. A method of removing proteinaceous stains from surfaces comprising such stains is also provided.

Claims

1. A detergent composition comprising;

a) a subtilisin variant having the amino acid sequence set forth in SEQ ID NO 1, and

b) at least one additional ingredient selected from;

i) bleaches selected from percarbonates, persulphates and organic peracids,

ii) aminocarboxylates, or

iii) sulphonated polymers, or

iv) organophosphoric acids or salts thereof, and mixtures thereof.

2. A detergent composition according to claim 1, wherein the composition is a laundry composition or a dishwashing composition.

3. A detergent composition according to claim 2, wherein the dishwashing composition is an automatic dishwashing detergent composition.

4. A detergent composition according to claim 1, wherein the subtilisin variant having the amino acid sequence set forth in SEQ ID NO 1 is an isolated variant.

5. A detergent composition according to claim 1, wherein the percarbonate or persulphate bleach comprises sodium or potassium percarbonate or persulphate.

6. A detergent composition according to claim 1, wherein the organic peracid comprises a perbenzoic acid and/or a peroxycarboxylic acid.

7. A detergent composition according to claim 6, wherein the peroxycarboxylic acid comprises monoperoxyphthalic acid, diperoxyphthalic acid, 2-octyldiperoxysuccinic acid, diperoxydodecanedicarboxylic acid, diperoxy-azelaic acid, imidoperoxycarboxylic acid or phthalimidoperhexanoic acid including derivatives and salts thereof and mixtures thereof.
