Disclaimer

At room temperature, concentrations over about 70% in water tend to form 1-2% thioglycolides per month which hydrolyze to the original free compound when made acid or alkaline. The 70% solution oxidizes in air but is stable at room temperature when tightly closed. Thioglycolate salts may also lose purity on storage. The exclusion of air does not materially improve stability.
