UVA-tracer containing disinfectant and method of determining the degree of dilution of disinfectants using UVA-tracers

摘要

Disinfectant composition which comprises a) one or more microbicidal active ingredient(s) and b) one or more UVA-tracer(s) chosen from benzophenone and its derivatives, anthranilic acid and its derivatives, pyrazoline and its derivatives, benzimidazole and its derivatives and triazine and its derivatives, and optionally further auxiliaries and/or solvents/solubility promoters; and method of determining the concentration of microbicidal active ingredients in disinfectants, in particular of determining the degree of dilution of disinfectants, in which a UVA-tracer is used together with the active ingredient, and the UVA-tracer concentration is determined by means of absorption spectrophotometry.
