Detergent composition
First Claim
1. A detergent composition comprising:
- a subtilisin variant having the amino acid sequence set forth in SEQ ID NO 1 present in an amount of from 0.005 wt% to 2 wt%,at least one bleach selected from percarbonates, persulphates and organic peracids present in an amount of from 1 wt% to 50 wt%,at least one aminocarboxylate present in an amount of from 20 wt% to 80 wt%,at least one sulphonated polymer, present in an amount of at least 0.5 wt% to 15 wt%, andat least one organophosphonic acids or salts thereof, and mixtures thereof, present in an amount of from 0.05 wt% to 5 wt%,wherein the detergent composition is an automatic dishwashing detergent composition,wherein the detergent composition is in the form of a multilayer tablet with a pill contained in a cavity in the topmost layer,wherein the detergent composition is at least partially enveloped in a water soluble or water dispersible package, andwherein the subtilisin variant is present in the pill and at least one layer of the multilayer tablet.

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) organophosphonic 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.
