Local Tolerance for chemicals

Vivotecnia offers global REACH expertise and full toxicology portfolio to support Safety Testing of Chemicals according to information requirements detailed in Annex VII-X of the REACH directive for skin and eye irritation and skin sensitization testing. We can perform these tests as stand-alone studies or as a part of a “Six-pack” for acute toxicity testing:


  • Skin irritation / corrosion (in vitro / in vivo)
  • Eye irritation / corrosion (in vitro / in vivo)
  • Sensitization (in vitro / in vivo)
  • Oral toxicity (OECD 423, 425 and 420)
  • Dermal toxicity (OECD 402)
  • Inhalation acute toxicity (OECD 403 and 436)
