COMPOSITION FOR TEMPERATURE-TIME INDICATOR OF AIR STERILIZATION Russian patent published in 2003 - IPC

Abstract RU 2210064 C2

FIELD: chemical technology. SUBSTANCE: invention relates to visual agents used for control of temperature and time of thermal treatment, in part, to chemical indicators of sterilization. Composition comprises succinic acid, carbonic acid amide or its derivative or sulfanilic acid amid, dye malachite green, colophony-maleic resin, nonionogenic surface-active substance, polyorganosiloxane, plasticizing agent and water taken in the definite ratio of components. Composition can comprise urea, thiourea or diphenylthiourea as carbonic acid amide or its derivatives and streptocide as sulfanilic acid amide. Oxyethylated alcohols or oxyethylated alkylphenols can be used as nonionogenic surface-active substances and polydimethylsiloxane or polydiphenylsiloxane can be used as polyorganosiloxane. Invention allows reducing energy consumption necessary for dispersing crystalline components. EFFECT: valuable properties of composition. 7 cl, 7 ex
