The bill amends the General Laws in Chapter 4-1, titled "Cruelty to Animals," to introduce new definitions and regulations regarding cosmetic animal testing. Key insertions include definitions for 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 circumstances 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.

Additionally, the bill stipulates that the prohibitions do not apply to cosmetics tested on animals before January 1, 2025, or to manufacturers reviewing or retaining evidence from a cosmetic animal test. It also prohibits any political subdivision of the state from establishing or continuing any prohibition on cosmetic animal testing that is not identical to the prohibitions set forth in this section.

Violations of the act will result in a penalty of up to $1,000 for each offense, with each day of continued violation considered a separate offense. The act aims to enhance animal welfare by prohibiting the sale of cosmetics tested on animals, thereby promoting alternative testing methods. The provisions of this act will take effect upon passage.
