Hazards of PER Alternatives

October 2016 - As of 2013, the French Authorities have decided to progressively stop the use of dry-cleaning machines that use Perchloroethylene (PER) as cleaning solvent (cf. arrêté 2345), which is widely used within textile cleaning for its unique properties, as it is the most efficient non-aqueous cleaning solvent, and provides a high level of safety to workers and surrounding buildings as it is non-flammable. 

Dry-cleaners in France are now forced to use alternative solvents with different physical properties that do not provide the same level of safety, in particular flammable solvents. Since the regulation came into force, several fires have broken out in dry-cleaning shops applying flammable solvents, that did only by chance not result in harm to shop workers and people living in the neighbourhood. ECSA would like to re-affirm that under controlled conditions PER is and remains the safest and most efficient solvent of choice for dry-cleaning. For decades ECSA is providing recommendations on the safe handling of PER in regards to machine operation and solvent recycling, to protect people and the environment against adverse exposure and spillage along the whole life cycle of PER.


Methylene chloride

December 2014 - Trained and certified professionals can use DCM based paint strippers in the UK.

The UK Authorities have launched in 2014 a public consultation that led to the vote by the UK Parliament for national amendments to REACH.

The amendments will allow in the UK the supply and professional use in the UK of paint strippers based on the solvent methylene chloride (dichloromethane, DCM) by introducing mandatory trainings and examinations of competence for competence for professional users. The UK Health and Safety (HSE) which was responsible for consulting on this proposal,  is currently developing the training syllabus and testing regime for professional users of DCM-based paint strippers with the assistance of Heath and Safety Laboratory.

Methylene chloride

July 2012 - Methylene Chloride confirmed as readily biodegradable

A new study conducted by ECSA on biodegradation of dichloromethane in a closed bottle test according to OECD guidelines resulted in this finding. The study was required after an international agreement was reached this year by the OECD Cooperative Chemicals Assessment Programme on the hazard assessment of dichloromethane, leading to intense discussions on the available data on biodegradation for the substance.

The focus of the OECD Cooperative Chemicals Assessment Programme is to derive OECD-wide agreed hazard assessments of chemicals. These are available to the public and can be used for risk assessment and other activities within national or regional programmes.

The substance dichloromethane was assessed under this programme by the OECD Member States end of last year. The available studies demonstrate that methylene chloride is rapidly biodegradable. However, these studies were judged insufficient by OECD to allow classification as readily biodegradable due to the volatility of the substance and lack of a suitable OECD guideline test (OECD 301).  A recently performed Closed Bottle test (OECD 301 D) with dichloromethane confirmed that this substance is rapidly and readily biodegradable.

The members of the European Chlorinated Solvent Association (ECSA) welcomed the test results which will lead to an update of both the REACH and the OECD assessment of methylene chloride.

Angelica Candido joins as ECSA Sector Group Manager

February 2019

This month, Angelica Candido started at Euro Chlor as Sector Group Manager for the European Chlorinated Solvents Association (ECSA) and European Fluorocarbons Technical Committee (EFCTC) Sector Groups.

Previously Ms. Candido worked as a toxicologist for Penman Consulting, where she managed and coordinated EU chemical registrations under REACH/CLP regulation (and occasionally non-EU) and related tasks. In this role, she coordinated medium/large testing programmes, which included collaborative relationships with clients, research organisations and third parties.

Angelica graduated in Toxicology and Environmental health at Utrecht University, where she focused on endocrine disruptor activities of crude and refined petroleum products.


TRI Authorisations granted

September 2018

Trichloroethylene (TRI) can be used safely under controlled conditions. Five authorisations have been granted to BlueCube Germany (a subsidiary of Olin) to continue to produce TRI for specific uses, for example Industrial Parts Cleaning. Customers of this producer can use TRI for these applications under the conditions set by the EU Commission and the defined risk management measures.


UBA PMT criteria published

February 2018

The German Environment Agency (UBA, Umweltbundesamt) has published the assessment of "Persistence, Mobility and Toxicity (PMT)" with the desire to protect drinking water sources. Applying conservative criteria for PMT as defined by UBA, perchloroethylene (PER) and trichloroethylene (TRI) appear as number 2 and 3 on the report. UBA also aims to establish PMT as an equivalent concern to identify SVHC substance for authorisation under REACH. ECSA does not consider SVHC identification using PMT criteria as the appropriate tool to improve drinking water quality due to this being a pure hazard based approach and thus does not consider risk. TRI is already listed in Annex XIV (authorisation) and today PER is handled almost exclusively in closed systems with no intentional emission to water or soil. For further information see the ECSA position paper on PER here.


New Study on Dichloromethane

February 2018

Together with HSIA, ECSA supported a study to clarify the mode of action of cancer formation for Dichloromethane (DCM). The study results have been published end of 2018. The outcome of the study shows that below the threshold there is no risk of cancer formation related to DCM.
