- 17 -PRESERVATIVE SOLUTIONS CONTAINING SODIUM DEHYDROACETATEWITH OR WITHOUT SODIUM BORATE DECAHYDRATE AND/OR DISODIUMEDETATEABSTRACT OF THE DISCLOSURESodium azide is used as a preservative or bacte-riostatic agent of various solutions such as hypertonicphosphate solution, cleaning solutions used in electroniccounting equipment, Sorensen's phosphate buffers, lyticagents E and F and the like. Unfortunately, sodium azide,when combined with lead or copper in sink plumbing canproduce explosive substances and also is capable of genera-ting toxic gases. By using sodium dehydroacetate with orwithout sodium borate decahydrate and/or disodium edetate,the disadvantages are removed and at the same time the ef-ficiency of the various solutions is not affected adversely.
