Claims
- 1. A germicidal-disinfectant detergent composition comprising (a) 0.5-5 weight percent of a biguanide germicide, (b) 0.5-5 mol of a metal chelating agent per mol of the biguanide germicide, and (c) 5-50 weight percent of at least one anionic surfactant.
- 2. The composition according to claim 1, wherein the metal chelating agent is selected from the group consisting of ethylenediaminetetraacetic acid, hydroxyethylethylenediaminetriacetic acid, diethylenetriamine pentaacetic acid, nitrilotriacetic acid, triethylenetetramine hexaacetic acid, phosphonic acids, tripolyphosphoric acid, ethylene glycol-bis(2-aminoethyl ether)tetraacetic acid, citric acid, maleic acid, polyacrylic acid, isoamylene-maleic acid copolymers, silicic acid, gluconic acid, hydroxybenzylimidinoacetic acid, imidinoacetic acid and salts thereof.
- 3. The composition according to claim 1, wherein the anionic surfactant is selected from the group consisting of salts of higher fatty acids, salts of higher alcohol sulfates, salts of higher alcohol sulfonic acids, salts of sulfated fatty acids, salts of sulfonated fatty acids, salts of higher alcohol phosphates, salts of fatty acid ester sulfates, salts of fatty acid ester sulfonates, salts of higher alcohol ether sulfates, salts of higher alcohol ether sulfonates, salts of higher alcohol ether-substituted acetic acids, condensates of a fatty acid and an amino acid, salts of fatty acid amide alkylolated sulfates, salts of fatty acid amide alkylated sulfonates, salts of carboxymethyl-substituted ethoxylated fatty acid amides, salts of sulfosuccinates, alkylbenzenesulfonates, alkylphenol sulfonates, alkylnaphthalenesulfonates and alkylbenzoimidazolesulfonates.
- 4. The composition according to claim 1, wherein the metal chelating agent is selected from the group consisting of ethylene-diaminetetraacetic acid, hydroxyethylethylenediamine-triacetic acid, citric acid, tripolyphosphoric acid and salts thereof.
- 5. A method for germicidal and disinfectant cleaning, which comprises the steps of cleaning a surface with a composition comprising (a) a cationic germicide, (b) a metal chelating agent present in a proportion of at least 0.5 mol per mol of the germicide and (c) at least one surfactant selected from anionic surfactants, nonionic surfactants and amphoteric surfactants.
- 6. The composition as claimed in claim 1, wherein said biguanide germicide is chlorhexidine.
- 7. The composition as claimed in claim 1, wherein said biguanide germicide is chlorhexidine gluconate.
- 8. A method for germicidal and disinfectant cleaning, which comprises the step of cleaning a surface with the composition of claim 1.
- 9. The composition as claimed in claim 1, wherein the amount of said metal chelating agent (b) in the composition ranges from 0.5-2 mol per mol of the biguanide germicide.
- 10. The composition as claimed in claim 9, wherein said amount of metal chelating agent (b)ranges from 1-2 mol per mol of biguanide germicide.
