1.[Preservatives based on methylisothiazolones in cosmetic products--theory and analysis].
Matissek R. Z Lebensm Unters Forsch. 1986 Oct;183(4):273-89.
Methyl isothiazolone formulations (Kathon CG) promoted as preservatives in the cosmetic field were investigated for their organic components by capillary gas chromatography/mass spectrometry. 2-methyl-3(2H)-isothiazolone and 5-chloro-2-methyl-3(2H)-isothiazolone were identified as effective major components and 4,5-dichloro-2-methyl-3(2H)-isothiazolone, 3-chloro-N-methyl-propionamide and dichloro-N-methyl-acetamide as minor components. Various methods like thin-layer chromatography with chemical and UV-detection, high-performance thin-layer chromatography using direct optical measurement, capillary gas chromatography with nitrogen selective thermionic detector, high-performance liquid chromatography with UV- resp. diode-array-UV-detector and UV-spectrometry were applied for detection and identification of the compounds. For quantitative determination it was necessary to obtain the corresponding purified isothiazolones as reference compounds.
