The potential toxicity of hazardous household agents is reviewed. For all household chemicals, the agent, its contents, toxicity, symptoms, and treatment are discussed. Three types of soaps and detergents are distinguished by chemical classification as nonionic, anionic, and cationic. Their contents, added agents, effects, lethal dose, and treatment are specified. It is noted that soaps and detergents also often contain antiseptics, bleaches, hydrocarbons, or pine oil. Ammonia (7664417), enzyme detergents, and bleaches are the other cleaning agents discussed. Dangers of mixing bleach with strong acid, strong alkali, weak acids, and laundry detergents are presented. Disinfectants may include a host of possibly toxic materials including sodium-hypochlorite (7681529), quarternary ammonium compounds, peroxides, phenol (108952), hexachlorophene (70304), and creosotes. Solvents such as cleaning and polishing agents include petroleum hydrocarbons and non petroleum solvents. Carbon-tetrachloride (56235), acetone (67641), amyl-acetate (628637), ethylene-dichloride (107062), methyl-alcohol (67561), and trichloroethylene (79016) are discussed as the most common solvents in household use. The dangers of lead (7439921) and cadmium (7440439) in ceramics and earthenware are noted. The most hazardous cosmetics are enumerated, and their toxicity rating, possible toxic ingredients, symptoms, and treatment are presented. Bath oils and salts, cleansing creams, deodorants, depilatories, hair preparations and dressings, hair dyes, hair tonics, permanent wave ingredients, fingernail preparations, perfume, shampoos, shaving creams, and after shave lotion are discussed.
