Abstract
A non-toxic solution to be used in the place of distilled or de-ionized water in autoclave sterilizers is disclosed. The solution renders the instruments placed in such sterilizers free of rust, spotting, and hastens the drying time of such instruments.
Claims4
A non-toxic liquid composition for autoclaves used for sterilizing and quick drying of previously cleaned medical instruments consisting essentially of:
- (a) about 0.05% to about 0.15% volume of a non-filming alicyclic amine anti-corrosion agent which is soluble in water and does not degrade between a temperature range of about 20.degree. C. to about 150.degree. C.;
- (b) about 0.05% to about 0.15% volume of block co-polymer anti-spotting quick-drying surfactant which is soluble in water and does not degrade between a temperature range of about 5.degree. C. to about 150.degree. C.;
- and
- (c) about 99.7% to about 99.9% volume of purified water treated to remove dissolved minerals and impurities;
- said liquid composition when used in a sterilizing autoclave within a temperature range of 20.degree. C. to 135.degree. C. preventing corrosion and spotting and promoting quick drying of prior cleaned medical instruments sterilized in said autoclave.

A non-toxic liquid composition for autoclaves used for sterilization and quick drying of previously cleaned medical instruments consisting essentially of:
- (a) about 0.05% to about 0.15% volume of an anti-corrosion agent consisting essentially of a non-toxic concentration of alicyclic amine which is soluble in water and does not degrade between a temperature range from about 0.degree. C. to about 150.degree. C.;
- (b) about 0.05% to about 0.15% volume of an anti-spotting quick-drying agent consisting essentially of a non-toxic concentration of polyoxypropylene-polyoxyethylene block co-polymer surfactant which is soluble in water and does not degrade between a temperature range from about 0.degree. C. to about 150.degree. C.;
- and
- (c) the remainder consisting essentially of distilled water;
- said liquid composition when used in an autoclave within the specified temperature range preventing corrosion and spotting and promoting quick-drying of prior cleaned medical instruments sterilized in said autoclave.
