| titleOfInvention | Composite for thermotemporary indicator of steam sterilization |
| abstract | FIELD: medicine. SUBSTANCE: invention proposes a composite comprising active nitric acid component presenting a combination of acid nitrate (acid as an oxidizing agent) with a neutralizing agent (base as a reducing agent) and recording component presenting pH-indicator or a mixture of pH-indicators that changes its color in an acid region and taken in the following ratio of components, wt.%: nitric acid active component, 90.0-99.9; recording component, 0.1-10.0. The composite can comprise nitrate amine salt as a nitric acid active component that combines both an acid-oxidizing agent and a base-reducing agent or a mixture of nitrate amine salt and neutralizing agent taken in the following ratio of components, wt.%: nitrate amine salt, 10.0-99.8; neutralizing agent, 80.0-0.1; recording component, 0.1-10.0. The composition may comprise urea nitrate or guanidine nitrate as a nitrate amine salt. The composition can comprise naphthylamine, phenylamine, phenolic or bis-phenolic antioxidants or their mixture, urea or its analogues (thiourea, diphenylthiourea and others) as a neutralizing agent. The invention provides stability of the composite final color for a long time after sterilization. EFFECT: improved properties of composite. 11 cl, 5 tbl, 5 ex |
