Method of making a formulation for deactivating nucleic acids

A method of making a formulation for deactivating nucleic acids, the method comprising the steps of:

• (a) separately dissolving solid forms of a corrosion-inhibiting agent and a wetting agent, the corrosion-inhibiting agent being phosphate, borate or sodium bicarbonate, and the wetting agent being a surfactant or detergent;
• (b) combining together the dissolved forms of the corrosion-inhibiting agent and the wetting agent to form a first mixture;
• (c) combining together the first mixture with a solubilizing agent to form a second mixture, the solubilizing agent being an organic solvent or an emulsifying agent;
• and
• (d) instructing a user to combine the second mixture with a deactivating agent to form the formulation, the deactivating agent being sodium hypochlorite or dichloroisocyanurate,
• whereby the concentration of the corrosion-inhibiting agent in the formulation is from about 10 mM to about 750 mM;
• whereby the concentration of the wetting agent in the formulation is from about 0.005% to about 1% (w/v);
• whereby the concentration of the solubilizing agent in the formulation is from about 0.001% to about 20% (v/v);
• whereby the concentration of the deactivating agent in the formulation is from about 0.06% to about 3% (w/v) if the deactivating agent is sodium hypochlorite;
• whereby the concentration of the deactivating agent in the formulation is from about 5 mM to about 400 mM if the deactivating agent is dichloroisocyanurate;
• and
• whereby each agent of the formulation will remain substantially in solution at 22° C.
