"...on July 22 ... the Organization for Economic Cooperation and Development (OECD) — an international group that, among other things, provides guidelines to its 32-member countries on methods to assess chemical safety—officially approved three commercially available in vitro models of human skin for use in chemical testing. Specifically, the new guideline (OECD Test No. 439) stipulates that the models can serve as an alternative to animals in tests for skin irritation, one of several human health endpoints for which chemicals are tested. Similar 3-D models were approved for corrosion tests in 2004, leaving many hopeful that soon it may be possible to the assess the full spectrum of a chemical's effects on human skin—from irritation to corrosion—without using live animals."
