The Food and Drug Administration’s proposal to ban the use of formaldehyde as an ingredient in hair relaxers and hair straighteners on the market in the U.S. has been pushed back yet again. The deadline for the agency's proposal, at this time, still remains unclear.

 takes a large step in shedding light on the potential harm that formaldehyde — a highly toxic, colorless gas — can cause to the many Black women and other women of color who typically use straightening products.

 that the federal agency proposed the ban and scheduled its implementation for April 2024. The first deadline for the scheduled ban implementation was missed and pushed back to July 2024. Most recently, the agency moved the target date 

On April 3, the FDA told NPR in an email that the action date for the proposed ban was set for April 2024 and that officials were "still developing the proposed rule."

At that time, a spokesperson declined to comment further about the timing or the ban's detailed content. 

But when pressed about the status of the ban to the federal agency in May and, most recently, this month, an FDA spokesperson

told NPR that the proposed rule "continues to be a high priority." They declined again to comment further about its timing or content.

When asked Friday for clarification about why there have been numerous delays in implementing the proposed ban, a spokesperson told NPR that the process for implementing proposed rules “takes time.”

"Before a proposed rule can be published in the Federal Register for public comment, it must be reviewed and approved within FDA and other parts of the Federal government," the FDA spokesperson

Allison Stevenson, an attorney who represents product manufacturers and retailers, says that while we should expect to see a ban on formaldehyde, it’s no surprise that the FDA has delayed the proposed ban several times.

“There are a lot of moving parts … this all falls under legislation that is still relatively new, in almost all respects. And so it’s not uncommon to see things get delayed for one reason or the other,” she said.

Stevenson predicts that the ban will likely not occur until 2025. She says the proposed ban is necessary to protect the health and safety of communities of color.

"The regulation is necessary to protect the health and safety of communities of color, Stevenson said. “I certainly don’t believe that the delay should be indicative to anyone that the FDA is not making this issue a priority,” she added.

What are the health risks associated with formaldehyde?

Formaldehyde is a toxic, colorless and strong-smelling gas that presents health hazards when breathed into the lungs or when it comes into contact with the eyes or skin, 

In 2022, researchers at the National Institutes of Health 

 that showed an increased risk of hormone-related cancer in women who have used the chemicals in their hair. The findings in the report were especially concerning for Black women, who are far more likely to report using such products, including many kinds of chemical relaxers, 

"We estimated that 1.64% of women who never used hair straighteners would go on to develop uterine cancer by the age of 70; but for frequent users, that risk goes up to 4.05%," lead author Alexandra White, the head of the National Institute of Environmental Health Sciences Environment and Cancer Epidemiology group, 

Once the gas is present in the air at levels exceeding 0.1 parts per million, those in contact with it can experience harmful side effects such as watery eyes, burning in the eyes, nose, and throat, coughing, wheezing, nausea, and skin irritation. (Essentially, the more exposure one has to products containing formaldehyde — in terms of time and concentration — the higher the health risk.)

The long-term effects associated with the use of formaldehyde

The use of formaldehyde can have several 

 which can include an increased number of headaches, asthma, contact dermatitis and possibly cancer. 

Hair relaxers and hair straightening products have also been 

 uterine cancer, breast cancer and even ovarian cancer — especially for Black women.

, more than 150 hair-straightening products on store shelves contain formaldehyde. Investigators discovered that products that claimed to be "formaldehyde-free," "organic," or even "natural" actually contained the highly toxic chemical when tested.

Aside from hair straighteners and smoothers, formaldehyde is used in glues, resins, dyes, textiles, disinfectants, building materials, automobile parts, embalming, and laboratories, 

according to the Centers for Disease Control and Prevention
