CIR expert-panel safety assessment covering ceteareth-25 among the ceteareth series. These nonionic PEG-ether emulsifiers were concluded safe as used in cosmetic formulations; related ceteareth-15 (1.5%) caused only minimal patch-test irritation and was not a sensitizer. Caveat: should not be used on damaged skin.
