1,2- diisononyl cyclohexanedicarboxylates is a plasticizer for the manufacture of plastic articles for sensitive applications such as children's toys, medical products or for the production of plastics for food packaging. Chemically, it belongs to the group of aliphatic esters.
The most well-known trade name of the plasticizer is Hexamoll DINCH. It was developed by BASF as an alternative to harmful to health plasticizer DEHP ( phthalate ), the production, the Group has set the end of 2005 in Europe. Since the beginning of October 2006, the positive decision of the European Food Safety Authority has occurred ( EFSA). 2007 1.2 - diisononyl cyclohexanedicarboxylates was " to come Directive 2002/72/EC relating to plastic materials and articles that are intended for contact with food contact " in the Annex III of added. This Directive was replaced May 1, 2011 by the European Regulation 10/2011. 1,2- diisononyl cyclohexanedicarboxylates is listed there in Annex I.
Extraction
The commercial production of 1,2- diisononyl cyclohexanedicarboxylates carried out either by catalytic hydrogenation of di-isononyl phthalate or by a Diels -Alder reaction and subsequent hydrogenation. In the catalytic hydrogenation of the aromatic portion of the molecule is converted by the formal addition of 6 hydrogen atoms in the cyclohexane ring. And the alkyl ester groups are not affected.
Use
1,2- diisononyl cyclohexanedicarboxylates is suitable as plasticizers in toys made of PVC and for the production of products in the medical industry. It is regulated in the context of global migration of 60 mg per kilogram of food and therefore suitable for a variety of products in contact with food such as packaging films, hoses or seals.
Human exposure
In urine samples from 1999 and 2003, no metabolites were 1,2- diisononyl cyclohexanedicarboxylates found. From 2006 to 2012, the proportion increased with a positive finding of 7 % to 98%.
