Abstract
Abstract The present invention relates to certain processes and compositions useful for inhibiting the growth of slime in water and, in particular, water used for industrial purposes; for example, in the manufacture of wood pulp, in the manufacture of paper, in cooling water systems, and in effluent water treatment. The novel processes and compositions of the present invention are processes of mixtures which show unexpected synergistic activity against microorganisms, including bacteria, (in particular Aerobacter aerogenes) fungi, and algae, which produce slime in aqueous systems which are objectionable from either an operational or aesthetic point of view. Specifically, the invention is directed to the use of compositions comprising a combination 1,3-dichloroacetone oxime acetate and polyoxyethylene sorbitol hexaoleate having an average of 40 oxyethylene groups.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
48 words
A composition for controlling the growth of the microorganism Aerobacter aerogenes which comprises a mixture of 1,3-dichloroacetone oxime acetate and polyoxyethylene sorbitol hexaoleate having an average of 40 oxyethylene groups wherein the weight ratio of the acetate to the hexaoleate ranges from about 95:5 to about 5:95 respectively.
Claim 2
Dependent Claim
48 words
A composition for controlling the growth of the microorganism Aerobacter aerogenes which comprises a mixture of 1,3-dichloroacetone oxime acetate and polyoxyethylene sorbitol hexaoleate having an average of 40 oxyethylene groups wherein the weight ratio of the acetate to the hexaoleate ranges from about 95:5 to about 5:95 respectively.
Claim 3
Dependent Claim
11 words
The composition of claim 1 where said ratio is about 50:50.
Claim 4
Dependent Claim
23 words
A composition of claim 1 wherein the weight ratio of the acetate to the hexaoleate ranges from about 80:20 to about 5:95 respectively.
Claim 5
Independent Claim
65 words
A method for controlling the growth of the microorganism Aerobacter aerogenes in an aqueous system which comprises adding to said system a growth inhibiting amount of a composition comprised of a mixture of 1,3-dichloroacetone oxime acetate and polyoxyethylene sorbitol hexaoleate having an average of 40 oxyethylene groups wherein the weight ratio of the acetate to the hexaoleate ranges from about 95:5 to about 5:95 respectively.
Claim 6
Independent Claim
65 words
A method for controlling the growth of the microorganism Aerobacter aerogenes in an aqueous system which comprises adding to said system a growth inhibiting amount of a composition comprised of a mixture of 1,3-dichloroacetone oxime acetate and polyoxyethylene sorbitol hexaoleate having an average of 40 oxyethylene groups wherein the weight ratio of the acetate to the hexaoleate ranges from about 95:5 to about 5:95 respectively.
Claim 7
Dependent Claim
22 words
A method of claim 4 wherein the weight ratio of acetate to the hexaoleate ranges from about 80:20 to about 5:95 respectively.
Claim 8
Dependent Claim
11 words
The method of claim 5 where said ratio is about 50:50.
Claim 9
Dependent Claim
37 words
The method of claim 5 wherein said composition is added to said system in an amount of from 0.1 to about 1000 parts per weight of said composition per million parts by weight of said aqueous system.
Claim 10
Dependent Claim
26 words
The method of claim 7 where said composition is added in an amount from about 1 to about 100 parts per million of said aqueous system.
Claim 11
Dependent Claim
16 words
The method of claim 8 wherein the aqueous system is that of a cooling water system.
Claim 12
Dependent Claim
18 words
The method of claim 8 wherein the aqueous system is that of a pulp and paper mill system.
