The information on the Summary is basic information and is not intended to provide emergency response information, medical information or treatment information. The summary should not be used to provide in-depth safety and health information. In-depth safety and health information can be found on the (extended) Safety Data Sheet (e)sds for the chemical substance. General Statement Carboxylic acids, di-, C4-6 The chemical carboxylic acids, di-, C4-6 (AGS Diacids) is a solid organic multi-constituent substance which is composed of three discrete carboxylic acids: adipic acid (C6), glutaric acid (C5) and succinic acid (C4). It is mainly used as monomer for the synthesis of polyurethanes and as intermediate for the synthesis of plasticizers. It is also used in the chemical industry for a wide range of applications, such as leather tanning, textile processing and water treatment. Based on available studies, the substance causes serious eye damage. Safety conditions of use must be observed for handling in industry, to avoid workers eye exposure. Consumer exposure to the substance is not expected.

Health Effects Human Health Safety Assessment Effect Assessment Acute Toxicity Oral/inhalation/dermal Irritation / corrosion Skin/eye/respiratory tract Sensitisation Toxicity after repeated exposure Oral/inhalation/dermal Genotoxicity / Mutagenicity Carcinogenicity Toxicity for reproduction Low acute toxicity after oral or dermal exposure, not resulting in classification. Low toxicity by inhalation expected based on data for adipic acid, not resulting in classification. Causes serious eye damage. Slightly irritating to the skin and irritation of the upper respiratory tract suspected, due to the acidic character of the substance but not resulting in classification. Not considered to be sensitizing. Not classified for repeated toxicity based on oral studies results. No reliable data available on repeated inhalation and dermal exposures. Not considered as genotoxic based on in vitro and in vivo tests results. Not expected to be carcinogenic based on results of oral repeated dose study and on data for the constituents. No adverse effect on fertility and development expected based on results of oral repeated dose study and of long-term oral toxicity study with adipic acid. Based on the above mentioned data, the substance carboxylic acids, di-, C4-6 is classified as hazardous for health according to EU regulation (EC) 1272/2008. Environmental Effects Environment Safety Assessment Effect Assessment Aquatic Toxicity Harmful to aquatic organisms (fish, daphnia, algae). Fate and behaviour Biodegradation Inherently biodegradable. Bioaccumulation potential Not potentially bioaccumulative (Log Kow = -0.55 0.162). PBT / vpvb conclusion The substance is considered to be neither persistent and bioaccumulative and toxic (PBT) nor very persistent and very bioaccumulative (vpvb). Based on available data, the substance carboxylic acids, di-, C4-6 is considered as harmful for aquatic organisms, but as it is inherently biodegradable and not potentially bioaccumulative, it is not classified as dangerous for the environment according to EU regulation (EC) 1272/2008.

Exposure Human health Carboxylic acids, di-, C4-6 are manufactured in industry in closed processes which ensure that the risk is controlled. However, workers may be exposed during (un)loading, mixing, sampling, analysis or maintenance operations and particularly in case of batch processes during the preparation and use of carboxylic acids, di-, C4-6 in formulations. Where there is a risk of exposure, it should be kept as minimum as possible and at a safe level (strictly below exposure limits, when applied) by the use of appropriate risk management measures as suitable collective and personal protective equipment, good industrial hygiene practices and risk communication through appropriate training of workers. Environment Based on its physico-chemical properties, carboxylic acids, di-, C4-6 are water soluble and have a low potential for volatility and bioaccumulation. The substance is expected to partition predominantly into the aquatic compartment and not to adsorb on soil or sediment particles. Gaseous emissions in the air are not expected. Carboxylic acids, di-, C4-6 are not persistent in the environment (inherently biodegradable). Due to these properties, an indirect exposure of humans to carboxylic acids, di-, C4-6 via the environment is not expected. Risk Management Recommendations Human health For industrial and professional uses of carboxylic acids, di-, C4-6 and as recommended for the use of any chemical product, workers must be well informed and trained and must refer to the extended Safety Data Sheet (esds). Where there is a risk of exposure to carboxylic acids, di-, C4-6 (during (un)loading, mixing, sampling, analysis or maintenance operations and particularly in case of batch processes ), it must be controlled by handling the substance under an adequate and efficient ventilation. Appropriate Personal Protective Equipment (PPE) must be worn (safety goggles, gloves, protective suit) as recommended in the esds. In case of exposure to dust or aerosol, a respirator with approved filter should be used. General industrial hygiene measures are required to ensure safe handling of the substance: Emergency equipment, immediately accessible; use well-maintained PPE; wash hands and skin following contact; do not eat, drink or smoke at the workplace. Environment All industrial aqueous releases that may contain the substance are controlled in accordance with the risk assessment and must be directed to a waste water treatment plant or incinerated in compliance with local regulation. Disposal, treatment or recycling of industrial waste must comply with applicable regulations to preserve environment. Carboxylic acids, di-, C4-6 GPS Safety Summary Rev. 0 November 2013 4/6
