Industry and regulatory bodies responsible for public health are actively assessing animal-free tests to reduce the requirement for Draize testing. Before 2009 the Organisation for Economic Co-operation and Development (OECD) had not validated any alternative methods for testing eye or skin irritation potential. However, since 2000 OECD had validated alternative tests for corrosivity, meaning acids, bases and other corrosive substances are no longer required to be Draize tested on animals. The alternative tests include a human skin equivalent model and the transepicutaneous resistance test (TER). In addition, the use of human corneal cell line (HCE-T cells) is also another good alternative method to test eye irritation on potential chemicals
