S. 640/H. 989: An Act promoting humane cosmetics and other household products by limiting the use of animal testing
MSPCA Position: Support
Sponsors: Senator Mark Montigny and Representative Jack Patrick Lewis
Status: Referred to Joint Committee on Environment and Natural Resources. Hearing held 10/21/2025.
Every year, tens of thousands of animals suffer and die in product testing in the U.S. In common toxicity testing, harsh chemicals are applied to an animal’s skin, forced down their throat or into their lungs, and dripped into their eyes. Pain relief may be withheld. This legislation would require manufacturers and contract testing facilities to use non-animal testing methods instead of traditional animal tests when a valid alternative exists. The bills apply to products such as cosmetics, household cleaners, and industrial chemicals, like those in paint; they do not apply to testing done for medical research, including testing of drugs or medical devices. Public support for the issue is high. A 2022 survey of Massachusetts voters reveals that 75% support requiring companies in the Commonwealth to use methods that don’t use animals so long as such an alternative is available.

Scientific leaders moving to alternatives. 21st century science is rapidly moving away from outdated animal tests as many faster, less expensive, and more human-relevant alternative methods have become available, including artificial human tissue, organs-on-chips, and sophisticated computer programs. This shift toward non-animal methods builds on recommendations of the U.S. National Research Council’s 2007 report, Toxicity Testing in the 21st Century, which lays the groundwork for a “paradigm shift” in safety testing. It also conforms to the bipartisan-supported 2016 Frank R. Lautenberg Chemical Safety of the 21st Century Act, which requires the EPA to minimize animal testing.
In 2019, the U.S. Environmental Protection Agency (EPA) emphasized that they remained committed to ending the use of mammals in science and testing, both in their own studies and in funding requirements. Additionally, in February 2020, the EPA issued final guidance that reduces unnecessary testing on birds in the pesticide registration review process, which is expected to save 720 test animals annually. And in July 2020, the EPA released guidance that reduces unnecessary testing on fish in the pesticide registration process, expected to save 240 test animals annually.
The National Institutes of Health (NIH) has also shifted its policies to place greater emphasis on human-based approaches rather than relying on animal models. In July 2025, for example, the agency announced that all grant applicants must consider non-animal methods. In the NIH’s own words, “this new emphasis on human-based research will accelerate medical advances, save animals, and help NIH achieve its crucial mission of improving human health.”
Non-animal test methods save time and money. Non-animal alternatives provide more efficient as well as more effective chemical safety assessment. Human cell-based tests and advanced computer models, for example, deliver human-relevant results in hours or days, unlike some animal tests that can take months or years.
Animal tests do not ensure human safety. No longer considered the gold standard of product testing, animal models carry serious scientific limitations. Different species can respond differently when exposed to the same chemicals, and even different sexes or sub-species can respond differently. Consequently, results from animal tests may not be relevant to humans, thereby under- or over-estimating health hazards. Alternative methods based on human biology are much more likely to provide results predictive of human responses.
Animals suffer in product tests. Every year, tens of thousands of animals suffer and die in product testing in the U.S. Thousands may be used for a single test, and they often suffer for months or years before being euthanized. The situation is all the more urgent given that mice, rats, and birds who have been purpose-bred for research make up roughly 95% of animals used in research and testing, and yet they are excluded from the protection of the Animal Welfare Act.
Changing landscape. California, New Jersey, New York, and Virginia have all passed legislation similar to this bill. Additionally, twelve states have passed laws to prohibit the sale of cosmetics newly tested on animals: California, Hawaii, Illinois, Louisiana, Maine, Maryland, Nevada, New Jersey, New York, Oregon, Virginia and Washington. As scientific and technological leader, and a top recipient of NIH funding, Massachusetts should embrace expanding the use of animal alternatives.
