Disinfectants sold and used in the United States must carry which registration number?

Disinfectants sold and used in the United States must carry an EPA registration number because the Environmental Protection Agency (EPA) is responsible for overseeing the regulation of pesticides and disinfectants. This registration number indicates that the disinfectant has been evaluated for effectiveness and safety when used according to the manufacturer's instructions. The registration process ensures that products meet specific standards to protect public health and the environment.

The registration indicates that the product has been approved for use and can effectively kill germs and pathogens on surfaces, which is crucial in settings like salons where hygiene is essential. The distinction of products under the EPA helps consumers and professionals identify reliable disinfectants that can be trusted in their daily practices, ensuring compliance with health and safety guidelines.
