FIELD: chemistry.
SUBSTANCE: group of inventions describes a method of making chemical indicator for ozone sterilisation control, as well as a chemical indicator for ozone sterilisation control. Method comprises preparation of indicator composition, application on paper base, impregnation with subsequent drying, indicator composition contains an acid main indicator, selected from a group comprising dibutyl phthalate, bromocresol purple, cresol red and thymol blue, polyethylene or polypropylene glycol and a buffer solution selected from a group comprising citrate-phosphate and carbonate buffer solution at following ratio of components, wt%: acid-main indicator - 0.05-1.0; polyethylene glycol or polypropylene glycol - 0.1-15; buffer solution - balance.
EFFECT: invention enables highly efficient control of parameters of mode of sterilisation of medical products in atmosphere of ozone and can be used in medical institutions or at food companies.
