What two government agencies are responsible for tracking chemicals for commercial use?

The two primary government agencies responsible for tracking chemicals for commercial use in the United States are the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA). The EPA oversees the regulation of chemicals under laws such as the Toxic Substances Control Act (TSCA), while OSHA focuses on ensuring workplace safety and health standards related to chemical exposure. Together, they help protect public health and the environment by monitoring and regulating the use of chemicals in various industries.
