How Safe is DHA?

HOW SAFE IS DHA?

 

 

The Federal Food, Drug, and Cosmetic Act (FD&C Act), Section 721 authorizes the regulation of color additives (other than coal-tar hair dyes), including their uses and restrictions. These regulations are found in Title 21, Code of Federal Regulations (21 CFR), beginning at Part 70. If a color additive is not permitted by regulation or is used in a way that does not comply with the specific regulation(s) authorizing its use, it is considered unsafe under the law. Such misuse of color additives causes a cosmetic to be adulterated.

 

DHA is listed in the regulations as a color additive for use in imparting color to the human body. However, its use in cosmetics--including sunless "tanning" products--is restricted to external application (21 CFR 73.2150). According to the CFR, "externally applied" cosmetics are those "applied only to external parts of the body and not to the lips or any body surface covered by mucous membrane" (21 CFR 70.3v).

 

In addition, no color additive may be used in cosmetics intended for use in the area of the eye unless the color additive is permitted specifically for such use (21 CFR 70.5a) DHA is not permitted for use in the area of the eye. The CFR defines "area of the eye" as follows:

 

"the area enclosed within the circumference of the supra-orbital ridge, including the eyebrow, the skin below the eyebrow, the eyelids and the eyelashes, and conjunctival sac of the eye, the eyeball, and the soft areolar tissue that lies within the perimeter of the infra-orbital ridge." (21 CFR 70.3s)

 

As with the lips and other areas covered by mucous membrane, the industry has not provided safety data to FDA in order for the agency to consider approving it for use in the area of the eye. Extra care should be taken informing clients to avoid breathing (hold breath when spraying face) the sunless product during the application process.  In addition, extra care should be taken to avoid direct application of the product into the eye area. Clients should be encouraged to wear eye protection during the spray tanning process.  It’s recommended to use a lip balm or other barrier product on the lips and it is also recommended to use disposable foam nose plugs in the nostrils to avoid contact with mucous membranes. 

 

A well ventilated spray tanning area is very important to you and your clients.  The most important step you can take towards safe ventilation is to invest in an effective air cleaner.  The Sunless Store offers a commercial extraction fan with a built in filter holder and comes with an Arm & Hammer pleated filter with a recommended MERV rating of 8.  As a technician, you’re the most exposed since you’re regularly performing the procedure. Your options for protective technician gear are disposable foam nose plugs or disposable masks that cover your nose and mouth. Technician glasses are also recommended for eye protection.

Clients with respiratory problems, pregnant women or those with serious health issues should consult with their doctor prior to getting a spray tan.  Contact dermatitis caused by DHA is rarely reported.  Most causes of sensitivity are likely due to other ingredients such as preservatives in the formulation.   If a reaction occurs, have your client shower immediately.
