What is it?
Tartrazine Yellow is a lemon yellow azo dye used primarily in foods and cosmetics.

People allergic to aspirin are often allergic to tartrazene. Tartrazine (Yellow No. 5) is a yellow food coloring used in foods, drugs, and cosmetics.  Foods colored to achieve a yellow, orange, or yellow-green color may contain tartrazine.  Laws have been proposed that would require tartrazine to be listed on labels.  However, this is not done in most cases.
Direct contact with foods or products containing Tartrazine Yellow may cause symptoms including burning, irritation and redness. Direct contact may occur on the skin, lips or mouth. It is possible, but rare, that ingestion of this substance could cause generalized symptoms such as itching or redness of the skin.

Skin contact with Tartrazine Yellow is required for it to cause a rash. Discontinuation of exposure to products containing Tartrazine Yellow should result in improvement and/or resolution of your dermatitis. By law, all products made in the US for topical use have the ingredients listed either on the product package or the box that contains it, so check the labeling of your skin care products for this ingredient. If there is no information ask your pharmacist or call the company directly. At work, request a material safety data sheet (MSDS) to help identify potential sources of exposure.
