Two-component cleaning and disinfecting system
View Patent ↗A disinfectant, sanitizer, germicide, mildicide, virucide, deodorizer, decontaminator and cleaning formulation for cleaning porous and non-porous materials in hospitals, institutions, farms, hotels, cruise ships, homes, schools and other environments is provided.

9. The disinfectant composition of claim 8 , wherein the tertiary amine oxide is N,N-dimethyldodecylamine N-oxide.
10. The disinfectant composition of claim 1 , wherein the second component includes an aqueous acidic solution containing:
10 to 20 wt. % hydrogen peroxide, and
the balance water.
11. The disinfectant composition of claim 1 , wherein the second component includes an aqueous acidic solution containing:
15 wt. % hydrogen peroxide, and
the balance water.
12. The disinfectant composition of claim 1 , wherein the first composition has a pH ranging from 8 to 10.
13. The disinfectant composition of claim 1 , wherein the first and second components are separately included in a kit adapted to be mixed prior to application.
14. The disinfectant composition of claim 1 , wherein the first component comprises:
24 g of N, N-bis(3-aminopropyl)dodecylamine,
34.5 g of alkyl (C 12 to C 18 alkyl) dimethylbenzyl ammonium chloride,
36 g of an ethoxylated alcohol[6EO groups, average] 0.1 to 8 wt. % of a non-ionic surfactant,
25 grams of potassium carbonate, and
380.5 g of deionized water; and
the second component comprises:
214.3 g of 35% aqueous acidic hydrogen peroxide, and
285.9 g of deionized water;
wherein the first and second components are maintained separate to be combined prior to application.
15. The disinfectant composition of claim 1 , wherein the first component comprises:
