FDA Stops Use Of Lead Acetate In Hair Dyes

Silver Spring, Maryland, USA : The U.S. Food and Drug Administration (FDA) said it took action today to remove lead acetate in hair coloring products given potential safety concerns about lead exposure from these products.

The agency issued a final rule in response to a color additive petition that repeals the regulation that allows for the use of lead acetate as a color additive in these products. This rule, when effective, removes the only authorization for the use of lead as an ingredient in cosmetic products.

“Today’s action is part of our commitment to protect Americans by reducing exposure to toxic elements and builds upon federal efforts to reduce exposure to lead,” said FDA Commissioner Scott Gottlieb, M.D. “In the nearly 40 years since lead acetate was initially approved as a color additive, our understanding of the hazards of lead exposure has evolved significantly. We now know that the approved use of lead acetate in adult hair dyes no longer meets our safety standard. Lead exposure can have serious adverse effects on human health, including for children who may be particularly vulnerable. Moreover, there are alternative color additives for hair coloring products that consumers can use that do not contain lead as an ingredient.”

This action is based on new scientific data that show there is no longer a reasonable certainty that there is no harm from the use of lead acetate as a color additive. In 1980, based on information presented in a color additive petition, the FDA originally permitted the use of lead acetate as a color additive in certain hair dye products that are typically applied over a period of time to achieve a gradual coloring effect. Because of this gradual effect, these products are sometimes referred to as “progressive” hair dyes.

Generally speaking, a color additive must be shown to be safe before it may be used to color foods, drugs, cosmetics, or certain medical devices. A color additive petition may be submitted to the FDA seeking to authorize a new use of a color additive by demonstrating the safety of its use.

Likewise, a color additive petition may be submitted to the FDA demonstrating that an authorized use of a color additive is no longer safe. If the FDA determines that the petition questioning the safety of an authorized color additive and other relevant information support the petitioned request, the agency will grant the request by repealing or amending the authorizing regulation.

Today’s action is in response to a color additive petition. Based on this petition and other relevant information, the FDA concluded that there is no longer a reasonable certainty of no harm from the approved use of lead acetate in hair coloring products. This decision takes into account that, according to the U.S. Centers for Disease Control and Prevention, there is no safe exposure level for lead; there were deficiencies identified in a 1980 study estimating exposure to lead from hair dye that originally supported its use; and the fact that blood lead levels in the U.S. have dropped significantly since 1980, so we no longer can conclude that potential exposure to lead from lead acetate-containing hair dyes is insignificant.

The FDA is exercising enforcement discretion for a period of 12 months from the effective date of the final rule regarding hair dye products that contain lead acetate to allow firms to reformulate products.

Consumers wishing to avoid these products during that time can identify the products by the listing of lead acetate as an ingredient and by the presence of the warning label – that states, in part: “For external use only. Keep this product out of children’s reach.” Some manufacturers have already begun to reformulate their products with another color additive that does not contain lead as an ingredient, bismuth citrate.

The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices. The agency also is responsible for the safety and security of our nation’s food supply, cosmetics, dietary supplements, products that give off electronic radiation, and for regulating tobacco products.

The new rule does not take effect for 12 months, but it ends the only remaining legal use of lead, a neurotoxin, in cosmetic products in the United States.

For the most part, the hair dyes that now contain lead acetate, such as Grecian Formula, are used to darken gray hair, according to the Environmental Defense Fund (EDF).

Along with new scientific data, the FDA’s decision was prompted by a petition opposing the use of lead as a color additive.

“In the last several decades, we’ve seen tremendous progress in reducing exposure to lead from major sources. Given this progress and wide recognition that there is no safe level of exposure, it may seem unbelievable that common hair dyes contain the neurotoxin—putting those who use the product and their children at risk,” said Tom Neltner, chemicals policy director at the EDF, one of the groups involved in filing the petition.

“[The] FDA’s decision is an important step to protecting people from a continued source of exposure to lead that is a more significant route than the agency originally thought over three decades ago,” Neltner said.

Now, there is no safe level of lead exposure, according to the U.S. Centers for Disease Control and Prevention.

Companies have 12 months to reformulate hair dye products that contain lead acetate. Consumers who want to avoid using these products during that time can check to see if lead acetate is listed as an ingredient or there is a warning label that states, in part: “For external use only. Keep this product out of children’s reach,” according to the FDA.

Some hair coloring product manufacturers have already started using another color additive that does not contain lead as an ingredient, the FDA added.
