In a joint draft opinion, three European Scientific Committees were of the preliminary view that the principle of the TTC approach in itself was scientifically acceptable for the safety evaluation of chemicals that occurred at low levels, but that its application was dependent on the quality, quantity and relevance of the toxicological data and on a reliable estimation of chemical exposure. Due to the limited exposure information generally available for cosmetic ingredients, and the many possible exposure routes, Committee members considered that the TTC approach was “in general not applicable for intentionally added or formed substances present in cosmetic products” or for impurities in cosmetic ingredients. Other applications of the TTC approach were also discussed.
