CFDA just approved two more testing methods for cosmetics —— In Vitro Skin Corrosion: Transcutaneous Electrical Resistance Test (TER) and Skin Photoallergy Test.
These two methods still involve animal testing. The testing methods will be used for cosmetic toxicological assessment and will be designated as test No.19 and No.20 in the “Cosmetic Safety and Technical Standard”. The Transcutaneous Electrical Resistance Test（TER）is to evaluate if chemical ingredients in cosmetics are corrosive to mammalian skin and the Skin Photoallergy Test is to check if repeated use of a cosmetic will cause photoallergy.
