What is a detergent? All detergents contain, in addition to water and a mixture of a variety of chemicals. It can be surfactants, corrosive acids / alkalis, solvents, preservatives, abrasives, paint and perfume. Detergent residues are hazardous waste. Acids are corrosive (low pH). Phosphoric acids and nitric acid are examples of acids that can be included in detergents and can be found in toilet cleaners and lime removers. Acids irritate the skin and eyes and can cause burns. Alkalis are also corrosive (high pH). Potassium and sodium hydroxide are examples of alkalis that can be contained in detergents and are present in oven cleaners and stoppers. Another example is sodium hypochlorite, which is found in chlorine. Alkalis, like acids, are corrosive and thus irritate the skin and eyes and can also cause burns.
