An effective disinfectant bleach must have a registration number from which agency?

The Centers for Disease Control and Prevention (CDC) focuses primarily on public health and disease prevention, but it does not regulate disinfectants or issue registration numbers. Instead, it provides guidelines and recommendations for disinfection practices, relying on the EPA's assessments of disinfectant products.

The Food and Drug Administration (FDA) regulates food, drugs, and medical devices rather than disinfectants. While some disinfectant products may be used in healthcare settings, they fall under the EPA’s jurisdiction for safety and efficacy, rather than the FDA.

Safety Data Sheets (SDS) are documents that provide information on the properties of chemical products, including hazards and safety measures. However, SDS does not refer to an agency that registers disinfectants. Instead, it is a resource that provides safety information required by OSHA for chemicals in the workplace.
