This bill amends the General Laws in Chapter 4-1, "Cruelty to Animals," by introducing new definitions and provisions related to cosmetic animal testing. It defines terms such as "cosmetic," "cosmetic animal testing," "cosmetic product," "cosmetic ingredient," "manufacturer," "non-functional constituent," and "supplier." The bill establishes that no manufacturer shall sell or offer for sale any cosmetic that was developed or manufactured using cosmetic animal testing conducted or contracted by the manufacturer or any supplier of the manufacturer on or after January 1, 2026.

Exceptions to this prohibition are outlined, including cases where testing is requested or required by federal or state regulatory authorities, conducted outside the United States, or conducted for products subject to specific federal regulations. The bill also specifies that the prohibitions do not apply to cosmetics or ingredients tested on animals before January 1, 2025, provided that no new animal testing occurs after January 1, 2026.

Additionally, the bill imposes penalties for violations, with fines of up to $1,000 for each offense, and specifies that each day of continued violation constitutes a separate offense. The act aims to enhance animal welfare by prohibiting the sale of cosmetics tested on animals. The provisions of this act will take effect upon passage.
