Complying with REACH

Since 2007, solvents have been regulated at the European level under the Registration, Evaluation, Authorisation and Restriction of Chemicals regulation, known as REACH.

REACH requires all manufacturers in Europe and importers to register detailed technical dossiers addressing the health, safety and environmental risks on each chemical substance. Several consortia exist to undertake this work collectively on behalf of the industry, including sharing research data.

ESIG provides guidance to solvent manufacturers and importers in Europe on ways to comply with REACH 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 the supporting DU sectors activities on Use Mapping that is recommended by the European Chemicals Agency (ECHA) – ENES website.

REACH Consortium

Hydrocarbon Solvents

The Hydrocarbon Solvents Consortium (HSC) prepares registration dossiers for hydrocarbon solvents. It’s led by the Hydrocarbon Solvents Producers Association (HSPA), which is part of the European Council of the Chemical Industry (Cefic).

The reference between the HSPA substances and the Chemical Abstracts Service number (CAS no.) can be found in the HSPA substance CAS no. relationship compilation.

You can learn more about consortium activities, including membership details, on the consortium’s official website.

Oxygenated Solvents

Various REACH consortia were created for the following oxygenated solvents, which are managed by ReachCentrum:

  • Glycol Ethers
  • Ethyl Acetate
  • Methylethylketone (MEK)/ Secondary Butylalcohol
  • Methylisobutylketone (MIBK)
  • Isopropanol (IPA)

Learn more about consortia activities on the ReachCentrum website. For REACH related information on any other oxygenated solvent, please contact the ESIG secretariat.

REACH aims to improve protection of human health and the environment while enhancing the competitiveness of the EU chemical industry and avoiding the fragmentation of the internal market.

REACH applies to all chemicals, not just those used in industrial processes but also those used in daily life.

REACH is managed by the European Chemicals Agency (ECHA).

GES, smart and simple

With more than 1,000 different solvents used in hundreds of different applications, industry needed a smart, simplified approach to develop the many exposure scenarios required.

Our solution was to develop a generic approach to consolidate the many different solvent applications into Generic Exposure Scenario (GES) titles covering Workers (Industrial and Professional), Consumers and the Environment. The almost 30 GES we developed cover around 90% of solvent uses today.

This cluster approach helped to substantially reduce complexity and harmonise compliance across the value chain.  The resulting scenarios are also applicable to other solvent-like materials.

Developing the GES was a collaborative effort with downstream users, including the European Solvents Volatile Organic Compounds Co-ordination Group (ESVOC-CG). This collaboration was vital to establish effective use mappings and a comprehensive phrase library.

GES advantages

  • Allows for consistent and efficient communication of solvent uses through the supply chain.
  • Provides a consistent framework to evaluate risks.
  • Creates a common basis for developing chemical safety assessments and reports.
  • Standardises terms for use in exposure scenario narratives and safety data sheets.

The science behind GES

Chemical Safety Assessments carried out for each GES are based on ECETOC TRA V3 model exposure predictions, allocation of common risk management measures (RMM) and have risk characterisation ratios (RCRs) that demonstrate safe use.

Several GES templates are available for reference when creating your own Worker and Consumer assessments, and also Specific Environmental Release Categories (SpERCs) to support associated environmental assessments.

DISCLAIMER: To the best of our knowledge and belief, the GES materials provided here are accurate, reliable and complete. We cannot, however, offer any warranties or guarantees. All users are individually responsible for their respective REACH registrations.


What is an 'Exposure Scenario' and when is it required?

REACH requires manufacturers and importers of chemical substances like solvents to develop Exposure Scenarios (ES) as part of their registration for substances classified as hazardous and sold at 10 tonnes per year. These scenarios describe the necessary conditions to ensure the safe use of solvents, preventing harm to the environment and human health. Further information can be obtained on the ECHA website.

Do the GES comply with the latest guidance from ECHA on ‘Use Descriptors’?

A GES has been developed for each main area of application for solvents (e.g. formulation and (re)packing, coatings, cleaning agents). For each GES Title, ‘Use Descriptors’ have been defined in accordance with the ECHA guidance R12 Use Descriptors. The Use Descriptor mappings are reviewed against each latest version of the R12 guidance to ensure alignment and comments are provided.

When were the GES last updated?

Since we started producing scenarios in 2009, we have regularly updated them as needed to respond to changes in the industry and regulatory requirements. If you have any suggestions or questions, let us know at

What should customers do on receipt of an SDS containing Exposure Scenarios (ES)?

When customers receive an updated SDS for a product requiring ESs, they will need to identify the relevant ES(s) for their particular uses. In addition, they will need to review the ESs to check whether their local situation is consistent with the operating conditions and risk management measures identified in the ES.

If a Downstream User’s (DU) use, or the conditions of use, does not appear to be covered, the DU has 12 months (REACH Article 37) from the receipt of the e-SDS to contact the supplier to request that they consider including their use/use conditions in their registration.

Further information can be obtained from ECHA.

If a product is classified as dangerous, why is there no exposure scenario on the eSDS (expanded Safety Data Sheets)?

The risk management measures for controlling exposure to substances classified because of their physico-chemical (physchem) properties, e.g. aspiration or skin dryness hazards, may be the same regardless of the type of exposure scenario.

Where these apply, the advised risk management measure may be included within the main sections of the SDS and not identified within the individual exposure scenarios.

This approach is changing. In the future, the advised risk management measures to control risks from physchem hazards will also be included in exposure scenarios annexed to the SDS. Specific details may still be included in the main sections of the SDS and referenced in the exposure scenario.

The extended-SDS is very long and complicated, what parts are essential for me to read and understand?


The European Chemical Agency (ECHA) and the European Council of the Chemical Industry (Cefic) have endorsed the GES approach.

In recognition of their strength and validity, the approach has been integrated into other industry tools and other references supporting REACH, including:

  • ECHA Chemical Safety Assessment and Reporting Tool (Chesar)
  • Cefic Chemical Safety Assessment Excel tool
  • Cefic ES for Communication (ESCom) Package incorporating Standard Phrases for use in Exposure Scenarios, which is also linked to The European Standard Phrases Catalogue for Establishing Safety Data Sheets (EuPhraC)

Other industries have used ESIG’s GES to comply with their own REACH requirements, including the mineral oil Industry (represented by CONCAWE) and the Lower Olefins and Aromatics consortium (LOA).
