Example 10
Solutions were prepared using stabilized hydrogen peroxide (Peroxal CG 50® Arkema, Inc.) and 2-propanol 99% (Spectrum Chemical, USP Grade) to make a composition comprising 40% stabilized hydrogen peroxide and 15% 2-propanol and a composition comprising 25% stabilized hydrogen peroxide and 15% 2-propanol. The solutions were placed on stability in Type I amber borosilicate glass screw-top vials and maintained at 25° C./60% relative humidity (RH); 40° C./75% RH; and 5° C. (refrigerated). The 25% stabilized H2O2/15% IPA solutions remained stable (“in specification” according to ICH Harmonised Tripartite Guideline: Stability Testing of New Drug Substances and Products Q1A(R2)”, current Step 4 version, dated 6 Feb. 2003) under the 40° C. conditions at 6 months, and under both the 5° C. and 25° C. conditions at 24 months. The 40% stabilized H2O2/15% IPA solutions remained stable (“in specification” according to ICH Harmonised Tripartite Guideline: Stability Testing of New Drug Substances and Products Q1A(R2)”, current Step 4 version, dated 6 Feb. 2003) under the 40° C. conditions at 6 months, and under both the 5° C. and 25° C. conditions at 24 months.
