Anti-androgenic chemicals as a class of related substances with cumulative toxicological effects

Scientists and regulators have known for decades that certain chemicals disrupt the actions of male hormones—identified collectively as androgens—in the body. Because of their effects, these chemicals are called anti-androgens or anti-androgenic chemicals.

During gestation, fetal testes begin producing testosterone, the critical hormone required to develop reproductive organs and genitalia. Insufficient production of testosterone leads to malformation of the genital tract that may need corrective surgery in infant boys and may result in reproductive health problems later in life. Ortho-phthalates (aka phthalates), known to interfere with the production of fetal testosterone, are considered anti-androgenic chemicals.

Although phthalates are perhaps the most recognizable group of anti-androgenic chemicals in the diet, there are others, including bisphenol A (BPA), propyl paraben, and certain pesticides used in food crops. Because they cause similar harmful effects, namely adverse health outcomes for male reproductive system, their safety assessment must take into account the cumulative effects of similar substances in the diet as established by law. But what does “cumulative effect” mean? Below, we use a recent study to explain what it means, why it is important, and why FDA is failing.

Tara Flour: A Reminder of the Real-Life Consequences of Broken GRAS

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: August 10, 2022

Tom Neltner, Senior Director, Safer Chemicals and Maricel Maffini, EDF consultant

This blog is the fifth in our Broken GRAS series where we explore the Food and Drug Administration’s (FDA) Generally Recognized as Safe (GRAS) system for novel chemicals added to food.

In the spring, folks who ordered from a company that sells pre-assembled smoothies and other frozen foods for home delivery, started getting sick—really sick—after consuming an item called “French Lentil and Leek Crumbles” (Crumbles). Daily Harvest, the manufacturer, recalled the product on June 17. A month later, Daily Harvest said it had ruled out various food-borne pathogens, mycotoxins, heavy metals, and major allergens and had “identified tara flour as the cause of the issue.”

By the end of July, FDA reported the product had been linked to 329 illnesses and 113 hospitalizations in 36 states—a surprising number for a product that sold only 28,000 items. Consumer Reports described the health effects as fever, fatigue, vomiting, diarrhea, and liver problems. At least 25 people who consumed the Crumbles required surgery to remove their gallbladders.

Understanding PFAS: Why a broad, transparent PFAS Testing Strategy is needed

By Maria Doa, PhD, Senior Director, Chemicals Policy / Published: March 2, 2022

Maria Doa, Senior Director, Chemicals Policy; Lauren Ellis, Research Analyst; and Lariah Edwards, Post-Doctoral Fellow

EDF this week sent EPA a letter identifying opportunities for the agency to improve the effectiveness and transparency of its strategy for testing per- and polyfluoroalkyl substances (PFAS).

EPA unveiled its National PFAS Testing Strategy (Testing Strategy) last fall, laying out its plan to better understand the class of chemicals and inform its future regulatory efforts. PFAS are a large group of synthetic chemicals used to impart water, oil, grease, and stain resistance to various materials, and they are used in hundreds of everyday products, from water-proof clothing to grease-proof food packaging. By its own count, EPA says there are more than 12,000 individual PFAS.

In their letter to EPA, EDF analyst Lauren Ellis and post-doctoral fellow Lariah Edwards commended the agency for developing a strategy to address some of the significant data gaps that exist around PFAS and committing to use its authority under the Toxic Substances Control Act (TSCA) ‒ the country’s main chemical safety law ‒ to require manufacturers to provide toxicity data on the chemicals.

As the letter points out, however, in its current state, the Testing Strategy lacks sufficient detail and is too narrow to fulfill the agency’s intended purpose to understand and regulate PFAS in a way that is protective of both human health and the environment. Read More »

FDA reinstates ban on lead added to hair dyes

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: October 8, 2021

Tom Neltner, Chemicals Policy Director

On October 7, FDA announced that it is reinstating its ban on lead acetate as the active ingredient in hair dyes that hide grey hair when used regularly. In 1980, the agency approved the chemical for hair dyes. In response to a color additive petition from the Environmental Defense Fund and others, in October 2018, the agency revoked its approval. Combe Inc, the maker of Grecian Formula, objected and forced the FDA to suspend its decision. With this new action, the FDA reinstates its decision effective January 6, 2022 and gives companies one year to reformulate lead acetate out of their products.

Grecian Formula reportedly stopped using lead acetate shortly before the FDA acted in 2018. From our searches, Youthair is the remaining brand that uses the chemical.

We applaud the FDA’s affirmation of its 2018 decision where it determined these products are not safe. The agency soundly rejects Combe’s arguments that low levels of lead are safe and concludes that “we have determined that there is no known level of exposure to lead that does not produce adverse effects” in adults. These adverse effects include heart and kidney damage.

People should not be spreading lead on their head! It gets through the skin where it can hurt their body in myriad of ways. While we applaud the decision, we don’t see anything in the record that explains why FDA took almost three years to reaffirm the obvious and allow consumers to unknowingly continue using the unsafe product. Therefore, it is even harder to understand why FDA chose to give Youthair another year – until January 2023 – to remove the product from the shelves.

The FDA has known for more than forty years that the lead in these hair dyes is absorbed through the scalp, especially when used every day to hide grey hair, but previously thought there was a safe level. Other federal agencies acknowledged a decade ago there is no known safe amount of exposure to lead in adults or children. The FDA’s action in 2018, reaffirmed today, brings it in line with the scientific consensus.

Beyond lead acetate hair dyes, the FDA needs to do more to drive down consumer’s exposures from all sources of lead in food and cosmetics by tightening limits on this heavy metal in common ingredients. To protect kids and adults, it needs to translate its recognition that there is no known safe level of lead exposure by updating its outdated standards for food additives, bottled water, metal cans, and brass faucets as we demanded in a petition last year. The agency’s Closer to Zero Action Plan for children’s foods is critical but not sufficient to protect adults.

FDA and industry continue to ignore cumulative effects of chemicals in the diet

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: September 24, 2021

Tom Neltner, Chemicals Policy Director and Maricel Maffini, consultant

The Food and Drug Administration (FDA) has made no apparent progress to comply with the legal requirement that it consider the cumulative effect of chemicals in the diet that have similar health impacts when evaluating the safety of an additive. A year ago, on September 23, 2020, EDF and 11 other organizations[1] filed a formal petition with the agency documenting the problem and asking it begin complying with the law.

We reviewed FDA and industry actions since the petition was filed and found that both continued to ignore the requirement 100% of the time in:

  • Generally Recognized as Safe (GRAS) notices in which companies were required to consider the cumulative effect as part of their determination that a substance’s use was safe;
  • FDA’s responses to those GRAS notices where it found “no questions” with the flawed safety determinations; and
  • FDA’s revised guidance to industry on use of recycled plastics in food packaging.

The agency’s only response to our petition was a March 2021 letter saying it “has not reached a decision due to competing priorities” and that the “petition is currently under active evaluation by [its] staff.”

From what we can see, FDA and industry continue to make safety determinations about chemical additives without regard to their overall effect on individuals’ health and their legal obligations. Is it any surprise that consumers continue to rate chemicals in food their #1 food safety concern? Read More »

Lead in hair dye – one company considers it safe

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: January 4, 2019

Tom Neltner, J.D., Chemicals Policy Director

In October 2018, the Food and Drug Administration (FDA) banned the use of lead acetate in hair dyes in response to a March 2017 color additive petition from EDF and other health advocates. In December, we learned that Combe, Inc., the maker of the lead-acetate based hair dye Grecian Formula, objected to FDA’s decision, requested a formal evidentiary public hearing to review the decision, and claimed the use is safe. The objection puts the FDA’s decision on hold awaiting a process that may take years to resolve. Apparently, the company thinks it is safe for men to slather skin-soluble lead on their head every couple of days and to risk exposing their families to a heavy metal for which no safe level of exposure has been identified.

Combe’s action was somewhat surprising because the company told CBS News that it removed lead acetate from its Grecian Formula “quite a long time ago,” but was unable to provide an exact date. Presumably, someone in the know updated the product’s Wikipedia page, which says Grecian Formula does not contain lead acetate as of July 2018, although an earlier version of the page said April 2018.

Whatever the date it was reformulated, why would Combe block FDA’s decision when it has long sold a lead-free brand – Just For Men – and had already reportedly removed lead from Grecian Formula? From a market standpoint, objecting to FDA’s decision benefits Youthair, Combe’s main competitor, which continues to sell a leaded-version of progressive hair dye.
