The U.S. Food and Drug Administration (FDA) has amended the color additive regulations to no longer provide for the use of atomic number 82 acetate in cosmetics intended for coloring hair on the scalp. This amendment was based on FDA's conclusion that the available information no longer demonstrates a "reasonable certainty of no damage" – the condom standard for a colour additive used in cosmetics – rather than on a decision that lead acetate in cosmetics intended for coloring the pilus on the scalp has been shown to cause harm under the conditions of use set forth in 21 CFR 73.2396.

On October thirty, 2018, the FDA published a terminal dominion to better the color additive regulations to no longer provide for the use of pb acetate in cosmetics intended for coloring hair on the scalp. On April 1, 2019, the concluding dominion was stayed because the agency received objections to its decision and a public hearing was requested inside the allowable timeframe. The agency has reviewed the objections and has determined that they did not raise issues of textile fact that justify a hearing. Therefore, on January 6, 2022, the terminal rule was made effective. We intend to exercise enforcement discretion for 12 months following the constructive date to provide manufacture with the opportunity to deplete their current stock and reformulate their hair dye products containing atomic number 82 acetate.

Color additives, with the exception of coal-tar pilus dyes, demand FDA approval earlier they're permitted for utilise in cosmetics.

The FDA's ability to take action against coal-tar hair dyes associated with safety concerns is limited by police force. It's important to follow the directions on the label. Information technology is also important to be an informed consumer and sympathise the risks.

What Are Coal-tar Hair Dyes?

The term "coal-tar colors" dates back to the fourth dimension when these coloring materials were by-products of the coal industry. Today, most are made from petroleum, simply the original proper noun is however used. Coal-tar hair dyes--those coal-tar colors used for dyeing pilus--include permanent, semi-permanent, and temporary pilus dyes.

Coal-tar colors are besides called "synthetic-organic" colors. That's because, to a pharmacist, a "synthetic" compound is 1 formed from simpler compounds and an "organic" compound is one that contains carbon atoms.

What the Law Says Virtually Coal-tar Hair Dyes

Under the Federal Food, Drug, and Cosmetic Act (FD&C Act), a police force passed by Congress, colour additives must exist approved past FDA for their intended employ before they are used in FDA-regulated products, including cosmetics. Other cosmetic ingredients exercise not need FDA approval. FDA tin accept action against a cosmetic on the market if it contains a poisonous or deleterious ingredient that may brand the cosmetic harmful to consumers when used in the customary or expected way and used according to labeled directions.

How the police force treats coal-tar hair dyes:

  • FDA cannot take action confronting a coal-tar hair dye on the basis that it is or contains a poisonous or deleterious ingredient that may make it harmful to consumers, as long as the label includes a special circumspection statement and the product comes with adequate directions for consumers to do a skin test before they dye their hair. This is the caution statement:
    Circumspection - This production contains ingredients which may cause peel irritation on certain individuals and a preliminary test according to accompanying directions should outset be fabricated. This product must not be used for dyeing the eyelashes or eyebrows; to do so may cause blindness. (FD&C Act, 601(a))
  • Coal-tar pilus dyes, unlike colour additives in general, do not demand FDA blessing. (FD&C Act, 601(e)).

But there are limits to this exception:

  • FDA may take activity against a coal-tar pilus dye product if—
    • it does not have the caution statement on its label or come with adequate directions for a skin test, or
    • an ingredient other than the coal-tar hair dye itself is harmful., or
    • it is otherwise adulterated or misbranded.
  •  "Coal-tar hair dyes" are not eyebrow or eyelash dyes. Color additives intended for dyeing the eyebrows or eyelashes need FDA approving for that apply. No color additives are canonical for dyeing the eyebrows or eyelashes.

Safety Issues

While many people use coal-tar hair dyes, FDA is aware of the following problems:

Eye injuries: Hair dyes take caused eye injuries, including blindness, when used in the center area. Eyebrow and eyelash dyeing are not permitted uses of coal-tar pilus dyes. To learn more, see "What does the constabulary say about coal-tar hair dyes?"

Allergic reactions: Some coal-tar pilus dyes tin can cause allergic reactions or sensitization that may result in skin irritation and hair loss. People can develop sensitivities with repeated exposure. In improver, formulations may change over fourth dimension. Then, information technology's possible to accept a reaction even if you have dyed your pilus in the past, without a problem. That's why it'due south important to follow the instructions and do the skin test before every use. Even if you don't see a reaction to the skin test, it'due south all the same possible to have a reaction when you dye your hair.

One hair dye ingredient, p-phenylenediamine, or "PPD," has been implicated more prominently in leading to allergic reactions. Some people may become allergic to PPD from other exposures, including occupational exposures. This is called "cross-sensitization." Here are some examples;

  • Some temporary tattoo inks, sometimes marketed as "blackness henna"
  • Certain material dyes, ballpoint pen inks, some color additives used in foods and drugs, and other dyes used in semi-permanent and temporary hair dyes
  • Rubber and other latex products
  • Benzocaine and procaine, local anesthetics used by doctors and dentists
  • Para-aminosalicylic acid, a drug used to care for tuberculosis
  • Sulfonamides, sulfones, and sulfa drugs
  • Para-aminobenzoic acrid (PABA), a naturally occurring compound used in some sunscreens and in some cosmetics.

Temporary tattoo artists who utilise coal-tar hair dyes to color people's peel are misusing these products and ingredients, considering coal-tar hair dyes are not intended to be used for staining the skin. While FDA regulates cosmetics products on the marketplace, professional practice is generally subject to land and local authorities, not FDA. To learn more, run into "Temporary Tattoos, Henna/Mehndi and 'Black Henna.'"

If you take a reaction to a hair dye or tattoo, enquire your healthcare provider well-nigh handling. If you lot know what ingredient caused the problem, you may be able to discover a product that doesn't incorporate that ingredient. If you colour your hair yourself, check the list of ingredients on the label for whatever y'all wish to avoid. If you have your hair colored at a salon, your stylist may be able to tell yous the ingredients, or you lot may wish to check with the manufacturer.

Questions about hair dyes and cancer: In the 1980s, some coal-tar pilus dyes were found to crusade cancer in animals. FDA published a regulation requiring a special warning statement for all pilus dye products containing these ii ingredients:

  • iv-methoxy-m-phenylenediamine ii,iv-diaminoanisole
  • ii, 4-methoxy-1000-phenylenediamine sulfate 2,iv-diaminoanisole sulfate

The cosmetic industry has since reformulated coal-tar pilus dye products, and we are no longer seeing these two ingredients in hair dyes.

FDA continues to monitor research on hair dye safety. We do non have reliable evidence showing a link betwixt cancer and coal-tar hair dyes on the market today. We are collecting adverse event data which helps the states assess the safety of this class of ingredients. If you experience an adverse event or bad reaction, please report that to the FDA (see below).
