Do you need a license to sell pet cleaning products containing isopropyl alcohol?

In the United States, a license is generally not required specifically to sell pet cleaning products containing isopropyl alcohol. However, sellers must comply with regulations set by the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA) regarding labeling, safety, and efficacy. Additionally, state and local regulations may impose specific requirements, so it's important to check local laws before selling these products. Always ensure that the products are safe for use around pets and humans.
