Physico-Chemical Property Testing Services for REACH submissions to complete a Safety Data Sheet (SDS) to meet requirements of Regulation (EC) No 440/2008

Physico-chemical property testing for REACH Registration, forms an integral part of the REACH standard information requirements and also for the registration of chemical substances in non-EU countries.

REACH Council Regulation (EC) No 440/2008 describes the physicochemical tests that you, as a registrant need to include in order to complete Safety Data Sheets (SDS).  Physicochemical data can be vital in designing the appropriate toxicological and ecotoxicological test packages and help predict toxicological or environmental hazards and behavior. The data can also have an impact on assessment of risk to human health and the environment during the product’s lifecycle, risk management and safety handling purposes.

Our physicochemical testing  capabilities are delivered in either packages or as stand-alone tests, to assess environmental impact or the safety of the chemical substance utilizing the physico-chem test methods listed in the REACH Council Regulation (EC) No 440/2008 (pursuant to Regulation (EC) No 1907/2006). 

We provide test data for physicochemical properties including melting temperature (A.1), boiling point (A.2), relative density (A.3), vapour pressure (A.4), surface tension (A.5), water solubility (A.6) and partition coefficient (A.8). We have particular expertise in the Phys-chemical testing requirements for polymers (A.18, A.19, A.20). Additionally, further phys-chem tests are available including granulometry, if required.

Our REACH and Regulatory testing analytical programs include substance ID, structural identity, purity, impurity profiles which are important when planning testing and can be used to quantify the phys-chem tests. We also provide sameness testing.

Beyond REACH, we have supplied physico-chemical data for our clients’ regulatory requirements for Classification, Labelling and Packaging (CLP) Regulation (EU) No 528/2012 (the EU Biocides Regulation), and agrichemicals working to OECD, CIPAC and EPA Test methods as appropriate.
