When diluting a product, one must be aware that the volume of the diluted solution may not be the sum of the volumes of product and water. For example, one ml of 5.25 wt% NaClO bleach added to ten liters of water, will yield a NaClO concentration of about 5.76 mg/L, and 5.48 mg/L of free chlorine. [24]
US government regulations (21 CFR 178 Subpart C) allow food processing equipment and food contact surfaces to be sanitized with solutions containing bleach, provided that the solution is allowed to drain adequately before contact with food and that the solutions do not exceed 200 parts per million (ppm) available chlorine (for example, one ...
0.5-2.5% sodium hypochlorite is also used to neutralize any accidental releases of the nerve agent in the toxic areas. [55] Lesser concentrations of sodium hypochlorite are used similarly in the Pollution Abatement System to ensure that no nerve agent is released into the furnace flue gas.
In the United States, food-grade lye must meet the requirements outlined in the Food Chemicals Codex (FCC), [5] as prescribed by the U.S. Food and Drug Administration (FDA). [6] Lower grades of lye that are unsuitable for use in food preparation are commonly used as drain cleaners and oven cleaners. [6] [page needed]

Food coloring allows us to bring new life to intricately decorated sugar cookies, gelatin desserts, and the frosting used to decorate layer cakes and cupcakes—and so much more.
Industrial setups allow for the reaction to be conducted in stages to give various compositions, each producing different ratios of calcium hypochlorite, unconverted lime, and calcium chloride. [3] In one process, the chloride-rich first stage water is discarded, while the solid precipitate is dissolved in a mixture of water and lye for another ...
