1,2-Cyclohexanedicarboxylic acid diisononyl ester, abbreviated DINCH, chemically belongs to the group of aliphatic esters. Like other plasticizers, DINCH is not chemically bound to the plastic and can therefore be released into the air or into dust (e.g. directly from a floor covering) by the product in question. However, the low volatility enables a very low concentration of DINCH in the air. A major advantage of DINCH is that it is not classified as genotoxic, carcinogenic or teratogenic.
During production, a mixture of different isomers is created, which is used as a plasticizer for the production of plastic items for sensitive areas of application such as children’s toys, medical products or for the production of plastics for the packaging of food. DINCH is a substitute plasticizer for phthalates and is therefore used in many household and construction products (e.g. floor coverings and wallpapers).
