Which government agency registers disinfectants and regulates them for use?

The EPA (Environmental Protection Agency) registers and regulates disinfectants in the United States. Salon disinfectants used on implements must be 'EPA-registered' and used according to the label. OSHA (Occupational Safety and Health Administration), by contrast, regulates workplace safety, including standards for handling hazardous chemicals and bloodborne pathogens. Knowing which agency does what — EPA for disinfectant registration, OSHA for workplace safety — is part of the safety and government-agency content on the cosmetology exam.
