Claims21
A method of disinfecting a surface in need of disinfection comprising applying to said surface a foam for a time sufficient to disinfect said surface, wherein said foam is prepared from an aqueous disinfectant formulation comprising:
- a) from about 0.05% to about 25% weight of at least one antimicrobial isolated or synthetic phenolic compound of natural origin selected from the group consisting of thymol and carvacrol;
- b) from about 0.1% to about 15% weight of an anionic, a cationic, an amphoteric, a non-ionic surfactant, or combinations thereof, in an amount sufficient to form a solution or dispersion of said phenolic compound in an aqueous carrier;
- c) from about 0.1% to about 40% weight of a solvent;
- d) from about 0.01% to about 10% weight of a sequestering agent selected from the group consisting of ethylene diamine tetraacetic acid (EDTA), sodium gluconate, citric acid, sodium citrate, trisodium NTA, trisodium ethylene disuccinate, sodium choleate, and a combination thereof;
- e) sufficient water to make 100 weight percent.
