Senate passes menstrual product ingredient-disclosure measure

The Massachusetts Senate on Oct. 16, 2025 passed an act requiring manufacturers of menstrual products to disclose all ingredients on product packaging and on manufacturer websites.

Sen. Joanne M. Comerford, who led floor remarks for the measure, told colleagues there are currently "no requirements under federal or Massachusetts law" that compel ingredient disclosure for menstrual products, and she listed health concerns raised by testing that has found PFAS, heavy metals and other chemicals in some products. The Senate adopted an amendment by Sen. Roderick, ordered the bill to a third reading and then passed it to be engrossed; the clerk's roll call recorded the vote as unanimous with no negatives.

Comerford credited student advocates, local organizers and organizations including MassNOW and the Massachusetts Menstrual Equity Coalition for bringing the issue forward. She said the measure follows similar steps already taken by New York, California and Nevada to require ingredient lists on products; the floor debate noted that after New York (effective 2021) and California (effective early 2023) enacted disclosure laws, several large national brands added ingredient lists to packaging and websites.

The bill requires manufacturers to list ingredients and to update labels and web disclosures if ingredients change. Supporters argued the policy will increase consumer information and market pressure for safer products. The measure moves next through the legislative engrossment process and will be laid before the governor for possible approval.

During debate, senators asked for a recorded vote; the clerk called the roll and recorded 39 affirmative votes and none negative. Specific implementing regulations, enforcement mechanisms or an agency responsible for compliance were not specified during floor remarks.
