Abstract

A disinfectant composition useful in shrimp aquaculture and a process for using such a disinfectant, in which there is a composition containinga) 25 to 87 wt. % of KHSO5 containing triple saltb) 1 to 20 wt. % of at least one H2N(CH2)nSO3H compound with n being 0, 1, 2 or 3,c) 1 to 8 wt. % of a surfactantd) 1 to 60 wt. % of a C2-C10 aliphatic dicarboxylic acid, optionally substituted with a hydroxyl and/or carboxylic group ande) 10 to 30 wt. % alkali metal phosphate.

First claim

What is claimed is:

1. A process for disinfecting water to be used for cultivation or containing aquatic shrimp cultures comprising adding a composition to the water, wherein said composition comprises
a) 25 to 87 wt. % of KHSO 5 containing triple salt;
b) 1 to 20 wt. % of at least one H 2 N(CH 2 ) n SO 3 H compound with n being 0, 1, 2 or 3;
c) 1 to 8 wt. % of a surfactant;
d) 1 to 60 wt. % of a C 2 -C 10 aliphatic dicarboxylic acid, optionally substituted with a hydroxyl and/or carboxylic group; and
e) 10 to 30 wt. % alkali metal phosphate.

2. The process for disinfecting water according to claim 1 , wherein the shrimps are aged 1 to 27 days after hatching.

3. A process for manufacturing a composition, said composition comprising
a) 25 to 87 wt. % of KHSO 5 containing triple salt;
b) 1 to 20 wt. % of at least one H 2 N(CH 2 ) n SO 3 H compound with n being 0, 1, 2 or 3;
c) 1 to 8 wt. % of a surfactant;
d) 1 to 60 wt. % of a C 2 -C 10 aliphatic dicarboxylic acid, optionally substituted with a hydroxyl and/or carboxylic group; and
e) 10 to 30 wt. % alkali metal phosphate,

wherein the process comprises blending together components a) to e).

4. A composition comprising
a) 25 to 87 wt. % of KHSO 5 containing triple salt;
b) 1 to 20 wt. % of at least one H 2 N(CH 2 ) n SO 3 H compound with n being 0, 1, 2 or 3;
c) 1 to 8 wt. % of a surfactant;
d) 1 to 60 wt. % of a C 2 -C 10 aliphatic dicarboxylic acid, optionally substituted with a hydroxyl and/or carboxylic group; and
e) 10 to 30 wt. % alkali metal phosphate.

5. The Composition composition according to claim 4 , wherein component b) comprises sulphamic acid.

6. The composition according to claim 4 , wherein component d) comprises C 4 -C 6 -aliphatic dicarboxylic acid that is unsubstituted or substituted by one or more hydroxyl and/or carboxylic group.

7. The composition according to claim 4 , wherein component d) comprises a aliphatic dicarboxylic acid selected from the group consisting of malic acid, citric acid, succinic acid, adipic acid, maleic acid and tartaric acid.

8. The composition according to claim 4 , wherein component c) comprises an alkali metal C 4 -C 20 -alkylarylsulphonate.

9. The composition according to claim 4 , wherein the composition contains
a) 35 to 72 wt. % of KHSO 5 containing triple salt,
b) 2 to 10 wt. %, of at least one H 2 N(CH 2 ) n SO 3 H compound with n being 0, 1, 2 or 3,
c) 1 to 6 wt. % of a surfactant,
d) 15 to 30 wt. % of a C 2 -C 10 aliphatic dicarboxylic acid, optionally substituted with a hydroxyl and/or carboxylic group and
e) 10 to 20 wt. % alkali metal phosphate.

10. The composition according to claim 4 , wherein the composition contains
a) 40 to 67 wt.% of KHSO 5 containing triple salt,
b) 2 to 10 wt. %, of at least one H 2 N(CH 2 ) n SO 3 H compound with n being 0, 1, 2 or 3,
c) 1 to 6 wt. % of a surfactant,
d) 20 to 30 wt. % of a C 2 -C 10 aliphatic dicarboxylic acid, optionally substituted with a hydroxyl and/or carboxylic group and
e) 10 to 20 wt. % alkali metal phosphate.

11. The composition according to claim 4 , wherein component d) comprises malic acid.

12. The composition according to claim 4 , wherein component c) comprises alkali metal C 10 -C 13 -alkylbenzenesulphonate.
