Senate approves menstrual product ingredient-disclosure measure
Summary
The Massachusetts Senate passed legislation requiring manufacturers to list menstrual-product ingredients on packaging and a website; sponsors cited state laws in New York and California as precedents and student-led advocacy as a driver.
The Massachusetts Senate on Oct. 16, 2025, passed an act requiring manufacturers of menstrual products to disclose the ingredients present in their products on product packaging and on the manufacturers’ websites. Sen. Joanne M. Comerford led floor remarks urging adoption, citing student organizers and public-health concerns about chemicals such as PFAS and heavy metals.
Comerford told the chamber the measure responds to constituent advocacy, including high-school students who raised health questions to state lawmakers, and that the bill follows steps taken by New York (enacted 2021), California (2023) and Nevada. “There are no current requirements under federal or Massachusetts law,” Comerford said, adding that many national brands have since posted ingredient lists after disclosure laws in other states took effect.
Senators adopted an amendment offered by Sen. Michael J. Rodericks and ordered the bill to a third reading; following a roll call the clerk recorded 39 votes in the affirmative and none in the negative, and the bill was passed to be engrossed.
Sponsors said the disclosure law would increase market incentive for manufacturers to label products and would complement the companion “I Am” bill to expand access to safe products. The bill’s text debated on the floor requires listing all ingredients and updating labels and online information if formulas change; sponsors said the language mirrors disclosure statutes already in effect in other states.
The measure now proceeds to final enactment procedures; the transcript records that the bill will be signed by the president of the Senate and laid before the governor for approval.
