Papan Bill to Restrict Harmful Synthetic Chemicals in Cosmetics and Personal Care Products Approved by the Legislature

SACRAMENTO, CA – Legislation authored by Assemblymember Diane Papan to protect public health and the environment has passed the California State Legislature and is now on its way to the Governor for consideration. Assembly Bill (AB) 60, known as the MUSK Reduction Act, will restrict the use of synthetic nitro musk chemicals in cosmetics and personal care products.

Nitro musks—synthetic fragrance compounds commonly found in soaps, perfumes, shampoos, and deodorants—have been in use for more than a century. Once used as a substitute for natural deer musk, these chemicals are now among the most persistent but toxic substances in consumer products. Nitro musks are endocrine-disrupting chemicals (EDCs) that interfere with hormone function. Repeated exposure has been linked to early puberty, reproductive disorders, infertility, and increased risks of breast cancer and other serious health conditions. These harms disproportionately impact women and young girls, particularly in communities of color and low-income areas, where access to safer alternatives is often limited.

“Women should not have to worry that their daily hygiene routine is exposing them to harmful chemicals that could disrupt their health,” said Papan. “California has a responsibility to act where federal regulations fall short. AB 60 will finally limit these toxic substances and protect women, young girls, and our environment from long-term harm.”

Studies have shown that girls today are experiencing puberty earlier than ever before, with chemical exposure identified as a significant factor. Early puberty is associated with higher risks of cancer, diabetes, heart disease, and other lifelong health challenges.

“Girls today are experiencing puberty earlier than ever before, and chemical exposure plays a significant role,” said Papan. “If we want to protect future generations from preventable health crises, we must act now to drastically reduce exposure to these dangerous toxins from everyday products.”

In addition to the health risks posed by nitro musks, these set of chemicals accumulate in wastewater, soil, sediment, marine life, and even the air we breathe.

Nitro musks are already banned or heavily regulated in 39 countries, including those in the European Union, New Zealand, and China. Yet, in the United States, no such restrictions exist, leaving Californians exposed to these toxic substances.

Assembly Bill 60 brings California in line with international health and safety standards by adopting restrictions similar to those enforced in the European Union. By eliminating nitro musks from cosmetics and personal care products, California will reduce toxic exposure, promote safer consumer choices, and protect environmental health.

Assembly Bill 60 is now enrolled to the Governor who has until October 12, 2024 to sign or veto the legislation.
