Abstract
Abstract A liquid cleaning and bleaching composition containing from 3 to 7% by weight of an alkali metal hypochlorite and from 0.5 to 8% by weight of a surface active agent having the formula ##STR1## wherein R 1 and R 2 are alkyls having from 1 to 13 carbon atoms with the proviso that the total number of the carbon atoms of R 1 and R 2 is from 8 to 14; and M is Li, Na or K.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
85 words
A liquid bleaching detergent composition, consisting essentially of an aqueous solution of: from 3 to 7 weight percent of sodium, lithium or potassium hypochlorite; from 0.5 to 8 weight percent of surfactant having the formula ##STR9## wherein R 1 and R 2 are alkyls having from one to 13 carbon atoms, with the proviso that the total number of carbon atoms of R 1 plus R 2 is from 8 to 14, and M is Li, Na or K; and the balance is essentially water.
Claim 2
Dependent Claim
85 words
A liquid bleaching detergent composition, consisting essentially of an aqueous solution of: from 3 to 7 weight percent of sodium, lithium or potassium hypochlorite; from 0.5 to 8 weight percent of surfactant having the formula ##STR9## wherein R 1 and R 2 are alkyls having from one to 13 carbon atoms, with the proviso that the total number of carbon atoms of R 1 plus R 2 is from 8 to 14, and M is Li, Na or K; and the balance is essentially water.
Claim 3
Dependent Claim
22 words
A composition as claimed in claim 1 in which the sum of R 1 plus R 2 is from 8 to 10.
Claim 4
Dependent Claim
71 words
A composition as claimed in claim 1 in which the sum of R 1 plus R 2 is from 11 to 14, and additionally containing a solubilizing agent selected from the group consisting of alkylbenzene sulfonates in which the alkyl has 3 to 8 carbons, water-soluble fatty acid soaps having 6 to 8 carbon atoms and water-soluble alkylbenzene carboxylate, the amount of said solubilizing agent being effective to dissolve said surfactant.

Claim 8
Dependent Claim
144 words
A liquid bleaching detergent composition, consisting essentially of an aqueous solution of: from 3 to 7 weight percent of sodium, potassium or lithium hypochlorite; from 0.5 to 8 weight percent of surfactant component consisting essentially of a. a first surfactant having the formula ##STR10## wherein R 1 and R 2 are alkyls having from one to 13 carbon atoms, with the proviso that the total number of carbon atoms of R 1 plus R 2 is from 8 to 14, and M is Li, Na or K; b. a second surfactant having the formula ROSO.sub.3 M wherein R is straight-chain alkyl having from 8 to 16 carbon atoms, and M has the same meaning as defined above said surfactant component containing from 50 to 100 weight percent of said first surfactant and the balance is said second surfactant; and the balance is essentially water.
Claim 9
Dependent Claim
144 words
A liquid bleaching detergent composition, consisting essentially of an aqueous solution of: from 3 to 7 weight percent of sodium, potassium or lithium hypochlorite; from 0.5 to 8 weight percent of surfactant component consisting essentially of a. a first surfactant having the formula ##STR10## wherein R 1 and R 2 are alkyls having from one to 13 carbon atoms, with the proviso that the total number of carbon atoms of R 1 plus R 2 is from 8 to 14, and M is Li, Na or K; b. a second surfactant having the formula ROSO.sub.3 M wherein R is straight-chain alkyl having from 8 to 16 carbon atoms, and M has the same meaning as defined above said surfactant component containing from 50 to 100 weight percent of said first surfactant and the balance is said second surfactant; and the balance is essentially water.
Claim 10
Dependent Claim
64 words
A liquid bleaching detergent composition as claimed in claim 7, in which said surfactant component contains from up to 60 weight percent of said first and second surfactants having a total number of carbon atoms of from 13 to 16, and the balance of said surfactant component is first and second surfactants having a total number of carbon atoms of from 10 to 12.
Claim 11
Dependent Claim
27 words
