NATIONAL LEAD Environmental Health Department W. L. MANN Manager August 1971 Mr. C. J. Cohen Lake Avenue M-2 Bristol, Connecticut 06010 Dear Mr. Cohen: Dr. J. F. Cole, Director, Environmental Health for the Lead Industries Association, Inc., has forwarded your inquiry regarding the use of titanium dioxide in paint. Titanium dioxide has been developed for, and is used extensively as a paint pigment, because of certain superior properties including toxicological and chemical inertness. Enclosed for your information is a list of tests and references which show that titanium compounds, principally titanium dioxide, are non-toxic for all normal purposes and uses, both as to human internal ingestion and external applications. We also enclose photo copies of the American National Standards Institute (formerly USA Standard) Z66.1-1964, entitled ''Specifications to Minimize Hazards I to Children from Residual Surface Coatings Materials" and the Ameri can Conference of Governmental Industrial Hygienists "Documentation for Titanium Dioxide". A typical analysis of the heavy metals content of our "TITANOX" pigments is as follows: Antimony Arsenic Cadmium Mercury Selenium Barium Lead 210 ppm < 5 ppm < 50 ppm d 0.025 ppm < 100 ppm 3 ppm 30 ppm You will note the heavy metals content is less than that permitted under the Z66.1 standard specifications, section 2, sub-par. 2. I trust you will conclude on your review of the attached material that the use of titanium in paint in no way constitutes a hazard even if it should be ingested accidentally.
