Antimicrobial Product Chemistry: Understanding EPA Requirements

The U.S. Environmental Protection Agency requires antimicrobial product registrants to provide product chemistry data to support purported label claims. Applicants must supply technical information describing the product’s active and inert ingredients, manufacturing or formulating processes, and physical an chemical characteristics. This white paper provides a simplified summary of the general guidance on these seemingly complex… Read More
