Abstract
Abstract The foaming performance in hard water of dishwashing detergent compositions containing dialkyl sulphosuccinates is enhanced by including in the composition a substantially water-soluble protein having a Bloom gel strength of at least 50 g, preferably from 150 to 300 g and especially from 200 to 250 g. The protein is advantageously a gelatin.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
34 words
A detergent composition suitable for dishwashing, characterised in that it comprises at least one detergent-active dialkyl sulphosuccinate and at least one substantially water-soluble protein having a Bloom gel strength of at least 50 g.
Claim 2
Dependent Claim
34 words
A detergent composition suitable for dishwashing, characterised in that it comprises at least one detergent-active dialkyl sulphosuccinate and at least one substantially water-soluble protein having a Bloom gel strength of at least 50 g.
Claim 3
Dependent Claim
59 words
A detergent composition as claimed in Claim 1, characterised in that the detergent-active dialkyl sulphosuccinate is a compound of the formula I: wherein each of R 1 and R 2 , which may be the same or different, is straight-chain or branched chain alkyl group having from 3 to 12 carbon atoms, and X 1 represents a solubilising cation.
Claim 4
Dependent Claim
42 words
A detergent composition as claimed in Claim 2, characterised in that it includes at least one dialkyl sulphosuccinate of the formula I in which at least one of the groups R 1 and R 2 has from 6 to 10 carbon atoms.
Claim 5
Dependent Claim
29 words
A detergent composition as claimed in any one of Claims 1 to 3, characterised in that the protein has a Bloom gel strength of from 150 to 300 g.
Claim 6
Dependent Claim
24 words
A detergent composition as claimed in Claim 4, characterised in that the protein has a Bloom gel strength of from 200 to 250 g.
Claim 7
Dependent Claim
20 words
A detergent composition as claimed in any one of Claims 1 to 5, characterised in that the protein comprises gelatin.
Claim 8
Dependent Claim
32 words
A detergent composition as claimed in Claim 6, characterised in that the protein is present in an amount of from 5 to 20% by weight, based on the total detergent-active material present.
Claim 9
Dependent Claim
78 words
A detergent composition as claimed in any one of claims 1 to 7, characterised in that it additionally comprises at least one anionic detergent-active agent selected from alkylbenzene sulphonates, secondary alkyl sulphonates, alpha-olefin sulphonates, alkyl glyceryl ether sulphonates, primary and secondary alkyl sulphates, alkyl ether sulphates, and fatty acid ester sulphonates; and/or at least one nonionic detergent-active agent selected from alcohol ethoxylates and propoxylates, alkyl phenol ethoxylates and propoxylates, alkyl amine oxides, and fatty acid mono- and dialkanolamides.
Claim 10
Dependent Claim
30 words
A detergent composition as claimed in Claim 8, characterised in that the weight ratio of total sulphosuccinate to other detergent-active material is within the range of from 1:4 to 20:1.
Claim 11
Dependent Claim
42 words
A detergent composition as claimed in any one of claims 1 to 9, characterised in that it is in the form of an aqueous solution having a total content of detergent-active material within the range of from 2 to 60% by weight.
