Titanium dioxide is the naturally occurring oxide of the metal, titanium. It is used in a wide range of applications from paint to sunscreen to food colouring.
How can I avoid it?
Skin contact with Titanium dioxide is required for it to cause a rash. Discontinuation of exposure to products containing Titanium dioxide 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.
