How solvent manufacturers can comply with REACH

Monday, 9 September 2019

ESIG, the European Solvents Industry Group, a Sector Group within Cefic, provides guidance to solvent manufacturers and importers on ways to comply with REACH requirements.

Since 2007, chemical substances including solvents have been regulated at the European level REACH. This requires all manufacturers within and importers to Europe (M/I) to register detailed technical dossiers addressing the health, safety and environmental risks of each chemical substance.

To comply with the regulation, companies must identify and manage the risks linked to the substances they manufacture and market in the EU. ESIG provides guidance to solvent manufacturers and importers on ways to comply with these requirements. Our Generic Exposure Scenarios (GES) are the solvents industry standard in Europe today to ensure REACH compliance through the supply chain and form the basis for supporting the Downstream User sectors activities on Use Mapping that is recommended by the European Chemicals Agency (ECHA).

Identify all substance uses

A key component of the registration of a substance under REACH is identifying all its uses and associated conditions of use throughout the supply chain. Already during the pre-registration phase of REACH (prior to 2010), Downstream Users were encouraged to interact with their suppliers and trade groups to ensure that the M/Iof their substances were aware of their uses and would include them in their Chemical Safety Assessments (CSA).

Once a (classified) substance is registered, the M/I is expected to communicate any safe handling measures resulting from the CSA to the DU in the Annex of the REACH extended Safety Data Sheet (SDS). DUs then have a legal obligation (REACH Article 37) to follow this advice, or demonstrate they have implemented equivalent measures. If their use or associated conditions of use are not covered, they have a number of options, including asking their supplier to update the registration, looking for an alternative supplier covering their use, substituting the substance for another with the relevant details, preparing own Downstream Users CSA.

Awareness of substance use

A chemical manufacturer first needs to be aware of the uses of their substances in order to evaluate the associated risks and this preferably with a high degree of consistency between substances with similar properties across different supply chains. It is then equally important that the outcome of this process, i.e. the SDS and its associated Exposure Scenario, is developed in a manner that is understandable and relevant for any DU of a given substance.

The process was led by the manufacturing trade group, ESIG. As part of the GES approach, ESIG has always worked with its downstream users’ sectors via the European Solvents Downstream User Cooperation Group (ESVOC) to align on use details and exposure conditions. About 30 DU associations or their partners were involved as early as 2008, including CEPE (the European Council of the Paint, Printing Ink and Artists’ Colours Industry), AISE (International Association for Soaps, Detergents and Maintenance Products), FEICA (the European Adhesive and Sealant Industry) and FEA (European Aerosol Federation) as direct members of the GES Working Group.

Consolidate substance uses

The solution was to develop a generic approach to consolidate the many different solvent applications into Generic Exposure Scenario (GES) Use Titles covering Workers (Industrial and Professional), Consumers and the Environment. The 22 GES Use Titles developed cover around 90 % of solvent uses today.

This cluster approach helped to substantially reduce complexity and harmonise compliance across the value chain – and the resulting scenarios are also applicable to other solvent-like materials. This is recognised as a major added value for registrants. As stated, developing the GES was a collaborative effort with downstream users via ESVOC and this collaboration was vital to establish effective use mapping and a comprehensive phrase library to support compilation of associated Exposure Scenarios within a company’s SDS system.

Formats and updates

The GES files for assessing Worker health risks were initially created using Microsoft Excel to meet the first Registration deadline in 2010. These files were then updated in 2014 using the Cefic CSA Excel tool and took account of feedback from solvent users who registered in 2010 and 2013. A second update took place in 2018.

Recent 2018 efforts have also focused on making it more efficient to conduct and report solvents Chemical Safety Assessments using the European Chemical Agency’s (ECHA) preferred tool, ‘Chesar’. After conducting a substance exposure assessment, Chesar enables users to directly populate the outputs into a Chemical Safety Report (CSR) and the REACH Registration tool, IUCLID. 

For each Use Title in the ESIG Worker GES library, a supporting xml transfer file allowing the auto-population of the details into Chesar is available. For Consumer GES, health exposure assessments are still carried out using the  Solvents EGRETv2 tool, which is outside of Chesar. However, the assessment output from EGRET can also be converted into an xml file that imports directly into Chesar. For Environmental assessments specific environmental release values (so-called SpERCs) have been compiled for each Use Title which are also available as Chesar import files.

There are occasions when a company may wish to carry out a standalone assessment for a substance for which the use of Chesar is not needed, for example for a confidential use or to demonstrate safe handling for a particular use with alternative Operational Conditions (OCs) or Risk Management Measures (RMMs) to those given in the Exposure Scenario provided with the substance SDS.  In any such cases, it may be more convenient to complete the assessment using the GES Worker files in the stand-alone Excel-tool format which, as mentioned, have also been updated in 2018.

Event tip

If you want to get more information on regulatory issues and get connected to regulatory experts from the coatings industry you should attend the European Coatings Regulatory Forum on 27-28 November. Early-bird registration is still open.
