Threshold of toxicological concern (TTC)
The Threshold of Toxicological Concern (TTC) represents a pragmatic approach that assumes for all chemicals a level of exposure at and below which there would be no risk to human health and has so far been applied mostly to food chemicals. A working group of leading experts in this field
has been assembled to investigate whether this concept can also be applied to cosmetics. The meetings attracted considerable interest from the European Commission services and observers of DG Sanco and ECVAM attended.
The results obtained by the end of 2005 are extremely promising and will be published in the scientific literature in 2006. Regulatory acceptance of this approach would reduce testing needs and facilitate risk assessments for impurities and low-concentration ingredients.
