What is it? 
Benzoic Acid is used in the preservation of foods, fats, fruit, antibacterial in mouthwashes, and an anti-fungal agent in pharmaceutical preparations and cosmetics 

How can I avoid it? 
Skin contact with Benzoic Acid is required for it to cause a rash. Discontinuation of exposure to products containing Benzoic Acid 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.
Direct contact with foods or products containing Benzoic Acid 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.
