    Sammanfattning : Preservatives are biologically active substances which are required in water-based products/systems to prevent growth of micro-organisms. Kathon® CG (K-CG), one of several preservatives based on 5-chloro-2-methyl-4-isothiazolinon-3-one (MCI) and 2-methyl-4-isothiazolin-3-one (MI) has been shown to be a common sensitizer in dermatitis patients.
