ALBANY, N.Y. (WENY) – New York State has become the first in the nation to require menstrual product packages or boxes sold in the state to disclose their ingredients.

The law, which was signed by Governor Andrew Cuomo Friday, will take effect in 180 days, and product makers will have 18 months to develop new packaging or labels with the ingredients.

Tampons, pads and other products typically are sold without disclosing what ingredients they contain. Recent studies have said these products may contain toxic and allergenic chemicals that could lead to significant health concerns in women.

"Practically every product on the market today is required to list its ingredients, yet these items have inexplicably evaded this basic consumer protection," said Cuomo. "It's part of the pervasive culture of inequality in our society that has gone on for too long, and that injustice ends today as we become the first state in the nation to mandate ingredient disclosure and empower women to make their own decisions about what goes into their bodies. This builds on the reproductive health protections that New York has safeguarded for women and girls across our state and we are proud to lead the nation by advancing these critically important new protections."

The bill was originally sponsored by NYS Assembly member Linda Rosenthal of Manhattan.

"Now that my bill to require menstrual product ingredient disclosure on packaging has become law, every single New Yorker who uses tampons and pads will know exactly what's in the products they use in and on some of the most sensitive parts of their bodies for 24 hours a day, seven days a week, one week out of the month for as many as 40 years,” said Rosenthal. “This first-in-the-nation disclosure law firmly establishes New York as a national leader on menstrual equity. Menstrual product ingredient disclosure is a vital consumer empowerment tool, and will hold menstrual product manufacturers to the highest level of accountability. It is my hope that more states follow suit."

Last year, Governor Cuomo signed legislation requiring all public schools to provide free feminine hygiene products in restrooms, as well as legislation to provide free products to women in state and local correctional facilities. In July 2016, Cuomo signed a law eliminating sales tax on menstrual products.
