The three moisturizers used in these mixtures are isostearyl isostearate (ISIS), isopropyl isostearate (IPIS), and glycerol monoisostearate (GMIS). Cholesterol sulfate is abbreviated to ChSO4; CER isolated from human SC is abbreviated to HCER; and CER isolated from pig SC is abbreviated to PigCER. CerA designates a mixture containing the first six synthetic CERs presented in Fig. 1.
