PORTLAND (AP) — Maine officials are almost finished with the public comment period on proposed regulations of household chemicals that could harm children and pregnant women in particular.

The proposal would elevate four phthalates from “high concern” to “priority chemical” status under state rules. Manufacturers would need to report the use of the chemicals in products sold in Maine.

The Maine Department of Environmental Protection is taking public comment until Tuesday.

Phthalates are used in products like raincoats and personal care items. The U.S. Centers for Disease Control and Prevention says some types of phthalates have affected reproductive systems in lab animals.

The Alliance for a Clean and Healthy Maine says the state’s proposal leaves pregnant women under-informed about which products — like cosmetics and shampoo — contain phthalates.
