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 substantially undegraded protein, such as soluble casein, sodium caseinate, soluble gelatin or chicken egg albumen.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
87 words
A detergent composition suitable for dishwashing, which comprises: (a) from 2 to 60% by weight of at least one detergent-active dialkyl sulphosuccinate of the formula I: ##STR2## 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; and (b) from 5 to 20% by weight, based on total detergent-active material present of at least one substantially water-soluble substantially undegraded protein.
Claim 2
Dependent Claim
87 words
A detergent composition suitable for dishwashing, which comprises: (a) from 2 to 60% by weight of at least one detergent-active dialkyl sulphosuccinate of the formula I: ##STR2## 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; and (b) from 5 to 20% by weight, based on total detergent-active material present of at least one substantially water-soluble substantially undegraded protein.
Claim 3
Dependent Claim
37 words
The detergent composition of claim 1, which 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 4
Dependent Claim
37 words
The detergent composition of claim 1, which 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 7 to 9 carbon atoms.
Claim 5
Dependent Claim
26 words
The detergent composition of claim 1, wherein the protein is selected from the group consisting of soluble casein, sodium caseinate, soluble gelatin and chicken egg albumen.
Claim 6
Dependent Claim
64 words
The detergent composition of claim 1, which additionally contains at least one anionic and/or nonionic detergent-active agent selected from the group consisting of alkylbenzene sulphonates, secondary alkyl sulphonates, αolefin sulphonates, alkyl glyceryl ether sulphonates, primary and secondary alkyl sulphates, alkyl ether sulphates, fatty acid ester sulphonates, alcohol ethoxylates and propoxylates, alkyl phenol ethoxylates and propoxylates, alkyl amine oxides, and fatty acid mono- and dialkanolamides.
Claim 7
Dependent Claim
26 words
The detergent composition of claim 5, wherein the weight ratio of total sulphosuccinate to other detergent-active material is within the range of from 1:4 to 20:1.
Claim 8
Dependent Claim
11 words
The detergent composition of claim 1, which is in liquid form.
Claim 9
Dependent Claim
32 words
The detergent composition of claim 7, which 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.
Claim 10
Dependent Claim
27 words
The detergent composition of claim 8, which further includes a viscosity control system comprising at least one material selected from lower alkanols, urea and lower alkylbenzene sulphonates.
