The bill seeks to amend the "Cruelty to Animals" chapter of the General Laws by introducing new definitions pertinent to cosmetic animal testing and establishing a ban on the sale of cosmetics developed or manufactured using such testing conducted by the manufacturer or their suppliers after January 1, 2025. The definitions added to the law include terms such as "cosmetic," "cosmetic animal testing," "cosmetic product," "cosmetic ingredient," "manufacturer," "non-functional constituent," and "supplier," which aim to provide clarity on the scope of the legislation. The bill maintains existing language on animal treatment and owner responsibilities, with exemptions for certain research facilities in compliance with federal regulations.

The bill outlines exceptions to the ban, allowing cosmetic animal testing when required by federal or state authorities, when no alternative methods are available, or when necessary to address specific human health risks. It also details conditions under which animal testing may be permissible, such as for research protocols, compliance with foreign regulations, or for non-cosmetic purposes under certain criteria. The bill exempts cosmetics tested on animals before January 1, 2024, provided no new testing occurs after January 1, 2025, and prohibits local governments from enacting non-identical bans. Violations would incur penalties of up to $1,000 per offense, with each day of continued violation considered a separate offense. The act would be effective immediately upon passage.
