Case story database

Search for Successfully Implemented Alternatives

You can use the free text search function to find information in the case story database. Most suitable are: substance name and other substance identifier (EC- and CAS-number). You can refine your search after first entry for sector-, function- and process-categories. The case studies are meant to serve as source of inspiration and ideas for substitution. The alternatives are constantly being developed further. We therefore recommend that you to check in each individual case whether an alternative is suitable for your applications and purposes. If you are aware of any other relevant information that is not mentioned in the current case story, please contact SUBSPORTplus.

Alternatives to 2-methoxyethanol as put forward by the European Chemicals Agency (ECHA)

This document concerns the general toxicity of 2-methoxyethanol and some common alternatives to its use in different applications. The most common substitutes for 2-methoxyethanol are: PGME, EGBE, ethylene glycol monopropyl ether (EGPE) and their acetates (PGMEA, EGBEA, EGPEA). The decision which alternative to use depends on what application 2-methoxyethanol is currently used in.

Different ways to phase out halocarbons like dichloromethane in various applications.

This document describes how a large portion of the halocarbons used and manufactured in Sweden were phased out during the late 1980´s and early 1990´s. Several specific examples are mentioned concerning what chemicals were substituted and what the alternatives were. The chemicals discussed are mainly: dichloromethane, trichloroethylene, 1,1,2-Dichloro-1,2,2-trifluoroethane and 1,1,1-trichloroethane.

Alternatives to diethyl ether containing adhesives for electrodes used in electroencephalograms

Exposure to a diethyl ether containing adhesive, used to attach the electrodes in long-term encephalograms (EEG), was incriminated for causing dizziness and headache to nurses but also to patients in two health care units in France. The case describes the exposure during different phases of the EEG, and proposes measures to replace the adhesive or to change the way electrodes are fixed, making the adhesive unnecessary.

Substitution of Chloroform with 1-Bromo-3-chloropropane in RNA-isolation.

Chloroform is commonly used in a method to isolate RNA from DNA and proteins. Since chloroform is a neurotoxicant, an endocrine disruptor and possibly also a carcinogen, substitution of the substance is advantageous from a workers' safety perspective. It was found that 1-Bromo-3-chloropropane (BCP) could work as a fully functional substitute for chloroform without any changes in the experimental process.

Substitution of toluene used as a solvent during the manufacture of sinks and other stainless-steel articles.

A company that manufactures sinks and other articles made of stainless steel used to apply a solvent that contained toluene, acetone and methanol. The solvent was used manually to clean the metal surfaces. Due to workers pressure the solvent was substituted with a safer alternative containing propan-2-ol and acetone.

Substitution of dichloromethane in the analysis of pesticide residue

In analysis of pesticide residues cyclohexane, ethylacetate, tert. butyl methyl ether, diethylether and light petroleum are tried as alternatives to dichloromethane. Conclusively cyclohexane, light petroleum or tert. butyl methyl ether is recommended in the article . Of these three recommended substances, light petroleum and tert. butyl methyl ether is included in the database of hazardous substances according to SUBSPORTplusS screening criteria (SDSC).

Substitution von Toluol als Lösungsmittel bei der Herstellung von Spülbecken und anderen Edelstahlprodukten.
