Biocidal textile treatment agent

1. Textile treatment agent comprising:

a biocidal compound used in an amount of 0.1 wt. % to 2.5 wt. % based on total weight of the agent, wherein the biocidal compound is a quaternary ammonium compound chosen from dialkyldimethylammonium halides,

wherein the dialkyldimethylammonium halide is selected from the group consisting of di-n-decyldimethylammonium chloride, didecyldimethylammonium bromide and dioctyldimethylammonium chloride,

a perfume composition, and

a non-ionic surfactant, wherein the non-ionic surfactant has an HLB value of from 10.5 to 15 and a cloud temperature of at least 50° C., and

wherein the ratio of non-ionic surfactant to perfume composition is greater than or equal to 5:1.

2. Textile treatment agent according to claim 1 , wherein the non-ionic surfactant has an HLB value of from 11 to 14.

3. Textile treatment agent according to claim 1 , wherein the non-ionic surfactant is an alkoxylated fatty alcohol.

4. Textile treatment agent according to claim 3 , wherein the non-ionic surfactant is an ethoxylated and/or propoxylated C 12 -C 18 fatty alcohol.

5. Textile treatment agent according to claim 1 , wherein the ratio of non-ionic surfactant to perfume is from 8:1 to 15:1.

6. Textile treatment agent according to claim 1 , wherein the textile treatment agent is a softener and further comprises a softening component.

7. Textile treatment agent according to claim 6 , wherein the softening component is an alkylated quaternary ammonium compound, wherein at least one alkyl chain is interrupted by an ester or amido group.

8. Textile treatment agent according to claim 1 , further comprising a biocidal compound chosen from amines, aldehydes, antimicrobial acids and salts thereof, carboxylic acid esters, acid amides, phenols, phenol derivatives, diphenyls, diphenyl alkanes, urea derivatives, oxygen acetals, oxygen formals, nitrogen acetals, nitrogen formals, benzamidines, isothiazolines, phthalimide derivatives, pyridine derivatives, guanidines, quinolines and mixtures thereof.

9. Textile treatment agent according to claim 1 further comprising 0.5 to 5 wt. %, ethanol and/or isopropanol.

10. Method of stabilizing a textile treatment agent comprising a biocidal compound used in an amount of 0.1 wt. % to 2.5 wt. % based on total weight of the agent, wherein the biocidal compound is a quaternary ammonium compound chosen from dialkyldimethylammonium halides, wherein the dialkyldimethylammonium halide is selected from the group consisting of di-n-decyldimethylammonium chloride, didecyldimethylammonium bromide and dioctyldimethylammonium chloride, and a perfume composition, the method comprising adding a non-ionic surfactant with an HLB value of between 10.5 and 15 and a cloud temperature of at least 50° C. to the textile treatment agent, wherein the ratio of non-ionic surfactant to perfume composition is greater than or equal to 5:1.

11. Method according to claim 10 wherein the textile treatment agent comprising the non-ionic surfactant with an HLB value of from 10.5 to 15 and a cloud temperature of at least 50° C. is stable during storage of the textile treatment agent at 0 to 10° C.

12. Method of producing a clear textile treatment agent comprising:

adding to the agent a non-ionic surfactant with an HLB value of from 10.5 to 15 and a cloud temperature of at least 50° C.,

the agent further comprising a biocidal compound used in an amount of 0.1 wt. % to 2.5 wt. % based on total weight of the agent, wherein the biocidal compound is a quaternary ammonium compound chosen from dialkyldimethylammonium halides, and a perfume composition,

wherein the dialkyldimethylammonium halide is selected from the group consisting of di-n-decyldimethylammonium chloride, didecyldimethylammonium bromide and dioctyldimethylammonium chloride,

wherein the ratio of non-ionic surfactant to perfume composition is greater than or equal to 5:1.
