Abstract

A germicidal-disinfectant detergent composition comprising (a) a cationic germicide, (b) a metal chelating agent and (c) at least one surfactant selected from anionic surfactants, nonionic surfactants and amphoteric surfactants is described. Excellent detergency and germicidal action are provided.

Claims

1. A germicidal-disinfectant detergent composition comprising (a) 0.5-5 weight percent of benzalkonium hexadecylphosphate, (b) a metal chelating agent and (c) 5-50 weight percent of at least one anionic surfactant selected from the group consisting of a salt of a higher fatty acid having 10-14 carbon atoms, a salt of a higher alcohol sulfate having 10-18 carbon atoms, a salt of a higher alcohol phosphate having 10-14 carbon atoms, and a salt of a higher alcohol ether sulfate having 10-18 carbon atoms,

wherein said metal chelating agent is present in an amount of 0.5-5 mol per mol of benzalkonium hexadecylphosphate.

2. The composition of claim 1, wherein said metal chelating agent is selected from the group consisting of EDTA, tripolyphosphonic acid or salt thereof, and citric acid or salt thereof.

3. The composition of claim 1, wherein said metal chelating agent is EDTA.

4. The composition of claim 1, comprising 0.5-5 weight percent metal chelating agent.

5. A method for germicidal-disinfectant cleaning, which comprises cleaning a surface with an effective amount of the composition of claim 1.

6. A germicidal-disinfectant detergent composition comprising (a) 0.5-5 weight percent of a benzalkonium chloride, (b) a metal chelating agent and (c) at least one anionic surfactant selected from the group consisting of a salt of a higher fatty acid having 10-14 carbon atoms, a salt of a higher alcohol sulfate having 10-18 carbon atom, a salt of a higher alcohol phosphate having 10-14 carbon atoms, and a salt of a higher alcohol ether sulfate having 10-18 carbon atoms,

wherein said metal chelating agent is present in an amount of 0.5-5 mol per mold of benzalkonium chloride.

7. The composition of claim 6, wherein said at least one anionic surfactant comprises a salt of a higher fatty acid having 10-14 carbon atoms.

8. The composition of claim 6, wherein said at least one anionic surfactant comprises a salt of a higher alcohol sulfate having 10-18 carbon atoms.

9. The composition of claim 6, wherein said at least one anionic surfactant comprises a salt of a higher alcohol phosphate having 10-14 carbon atoms.

10. The composition of claim 6, wherein said at least one anionic surfactant comprises a salt of a higher alcohol ether sulfate having 10-18 carbon atoms.

11. The composition of claim 6, wherein said metal chelating agent is EDTA.

12. The composition of claim 7, wherein said metal chelating agent is EDTA.

13. The composition of claim 8, wherein said metal chelating agent is EDTA.

14. The composition of claim 9, wherein said metal chelating agent is EDTA.

15. The composition of claim 10, wherein said metal chelating agent is EDTA.

16. The composition of claim 6, comprising 0.5-5 weight percent metal chelating agent.

17. A method for germicidal-disinfectant cleaning, which comprises cleaning a surface with an effective amount of the composition of claim 6.
