What Are Coal-tar Hair Dyes?

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

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

What the Police Says About Coal-tar Hair Dyes

Nether the Federal Food, Drug, and Corrective Human activity (FD&C Human action), a law passed by Congress, colour additives must exist approved by FDA for their intended apply earlier they are used in FDA-regulated products, including cosmetics. Other cosmetic ingredients do not need FDA approval. FDA can have activeness 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 law treats coal-tar hair dyes:

  • FDA cannot accept action against a coal-tar hair dye on the basis that information technology is or contains a poisonous or deleterious ingredient that may make it harmful to consumers, as long as the characterization includes a special caution statement and the product comes with adequate directions for consumers to exercise a pare test before they dye their hair. This is the caution argument:
    Caution - This product contains ingredients which may cause skin irritation on certain individuals and a preliminary exam according to accompanying directions should starting time be made. This production must not be used for dyeing the eyelashes or eyebrows; to do so may cause incomprehension. (FD&C Human action, 601(a))
  • Coal-tar hair dyes, dissimilar color additives in general, do not need FDA approval. (FD&C Act, 601(e)).

Only there are limits to this exception:

  • FDA may take action against a coal-tar pilus dye product if—
    • information technology does non accept the circumspection argument on its label or come with acceptable directions for a skin examination, or
    • an ingredient other than the coal-tar pilus dye itself is harmful., or
    • it is otherwise adulterated or misbranded.
  •  "Coal-tar pilus dyes" are non eyebrow or eyelash dyes. Color additives intended for dyeing the eyebrows or eyelashes demand FDA approval for that use. No colour additives are approved for dyeing the eyebrows or eyelashes.

Safety Issues

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

Heart injuries: Pilus dyes accept caused eye injuries, including blindness, when used in the eye area. Eyebrow and eyelash dyeing are not permitted uses of coal-tar hair dyes. To learn more than, see "What does the police say about coal-tar hair dyes?"

Allergic reactions: Some coal-tar hair dyes can cause allergic reactions or sensitization that may result in skin irritation and hair loss. People can develop sensitivities with repeated exposure. In addition, formulations may change over fourth dimension. So, information technology's possible to have a reaction even if you have dyed your hair in the past, without a trouble. That's why it'due south important to follow the instructions and do the skin test earlier every use. Fifty-fifty if you don't see a reaction to the pare exam, it's yet possible to have a reaction when yous dye your hair.

Ane 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 "cantankerous-sensitization." Here are some examples;

  • Some temporary tattoo inks, sometimes marketed every bit "black henna"
  • Certain cloth dyes, ballpoint pen inks, some colour 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 acid (PABA), a naturally occurring compound used in some sunscreens and in some cosmetics.

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

If you lot have a reaction to a hair dye or tattoo, ask your healthcare provider about treatment. If you know what ingredient caused the trouble, you may be able to discover a product that doesn't contain that ingredient. If you color your hair yourself, cheque the list of ingredients on the characterization for any you wish to avert. If you have your hair colored at a salon, your stylist may be able to tell you the ingredients, or you may wish to check with the manufacturer.

Questions nigh hair dyes and cancer: In the 1980s, some coal-tar hair dyes were establish to cause cancer in animals. FDA published a regulation requiring a special warning statement for all hair dye products containing these two ingredients:

  • 4-methoxy-thou-phenylenediamine 2,4-diaminoanisole
  • 2, 4-methoxy-k-phenylenediamine sulfate 2,4-diaminoanisole sulfate

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

FDA continues to monitor research on pilus dye safe. Nosotros do non take reliable evidence showing a link between cancer and coal-tar hair dyes on the market place today. We are collecting adverse event data which helps us assess the prophylactic of this class of ingredients. If you feel an adverse result or bad reaction, please study that to the FDA (see below).
