1 Technical information GPS Safety Summary ELATUR CH (Cyclohexane-1,2-dicarboxylic acid, diisononyl ester) Substance name Cyclohexane-1,2-dicarboxylic acid, diisononyl ester CAS-No General Statement Cyclohexane-1,2-dicarboxylic acid, diisononyl ester is mainly used as plasticiser in polymer formulations, especially together with PVC, PAMA and PVB. The advantageous properties of the high molecular weight ester are apparent in every method of thermoplastics processing and also in the processing of plastisols, as well as in the performance of all kinds of the finished products. It is also used in other technical products like e.g. in adhesives. Chemical identity Name Brand names Chemical name (IUPAC) Cyclohexane-1,2-dicarboxylic acid, diisononyl ester ELATUR CH CAS number Molecular formula C 26 H 48 O 4 Chemical characterization Synonyms Cyclohexane-1,2-dicarboxylic acid, diisononyl ester High molecular weight ester AG GPS Safety Summary S Juni 2013 Version 1 page 1/5

2 Uses and application Cyclohexane-1,2-dicarboxylic acid, diisononyl ester is used as a plasticizer for polymers, as phlegmatizer (for organic peroxides), in construction chemicals, for the manufacture of coatings, inks and colors, for the production of lubricants and the production of adhesives. Its predominant use is as a plasticizer for PVC in all kind of (soft) PVC-products especially flooring applications, wallpapers, coated fabrics, roofing membranes, hoses, profiles, artificial leather and wire & cable applications. In these applications Cyclohexane-1,2-dicarboxylic acid, diisononyl ester is always included in the PVC-matrix. The advantageous properties of the plasticizer ELATUR CH are apparent as described in the general statement.

3 Health effects Effect Assessment Acute toxicity (oral, dermal and inhalation) Eye / Skin irritation Sensitization Toxicity after repeated exposure Genotoxicity/mutagenicity Carcinogenicity Toxicity for reproduction Low order of acute toxicity by the oral, dermal and inhalation routes of exposure. Slight irritation to skin possible. No eye irritation observed. Not considered to be sensitizing Target organ effects specific to rodents are not relevant to human health Not mutagenic/genotoxic No cancer effects in animal tests. Not considered to be a human cancer concern No adverse effects on fertility and not selectively toxic to the fetus Environmental effects Effect Assessment Aquatic toxicity Not toxic to water organisms in the range of water solubility. Fate and Behavior Biodegradation Bioaccumulation potential PBT / vpvb conclusion Biodegradable Not bioaccumulative Neither considered to be PBT nor vpvb Exposure Human health Because Cyclohexane-1,2-dicarboxylic acid, diisononyl ester is included in the polymer matrix of soft PVC exposure is very limited. Very small amounts may migrate from the PVC. However resulting amounts exposed to humans are negligible. Environment Because Cyclohexane-1,2-dicarboxylic acid, diisononyl ester is included in the polymer matrix of soft PVC exposure is very limited. Very small amounts may migrate from the PVC. However resulting concentrations in aquatic environment are negligible. AG GPS Safety Summary Juni 2013 Version 1 page 3/5

4 Risk management recommendations Industry use, production and formulation Handle in accordance with good industrial hygiene and safety practices. Wear personal protective equipment; eye protection, gloves e.g. nitrilebutadiene rubber (NBR) If possible, use material transfer/filling, metering and blending plants that are closed. Normal measures for preventive fire protection. When handling ELATUR CH higher vapor concentrations have to be avoided (see physical/chemical properties). Consumer use The substance is used in articles e.g. soft PVC-articles where it is bounded in the polymer matrix. Recommendations from the article producer should be observed. State agency review EU REACH registration number: Regulatory information/classification and labelling GHS-Labelling Labelling not required according to EU GHS regulation, however according to UN-GHS classification as skin irritation category 3 is appropriate.
