It is used as an antacid to treat heartburn, indigestion, and upset stomach. Sodium bicarbonate is a very quick-acting antacid. It should be used only for temporary relief. If you need to treat long-term stomach acid problems (such as peptic ulcer disease, GERD), talk with your doctor about other medications.
In the industry, sodium perborate is used as a disinfectant. It is also part of the ingredients for detergents, bleach powders, and personal care formulations. In cosmetic products, perboric acid and mainly its salt are used as an oxidizing agent for dyeing or permanent waving.
With topical application, sodium perborate is converted by catalase to water, oxygen, and hydrogen peroxide. Its antimicrobial properties are attributed to oxidization of cell membranes, membrane-bound enzymes, and disruption of protein synthesis.
