Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Materials and methods

Test guideline
no guideline available
Principles of method if other than guideline:
Study to explore using the MCR approach,whether health risks due to indoor air pollution are dominated by one substance or are due to concurrent exposure to various substances. The MCR (maximum cumulative ratio) method allows the categorisation of mixtures according to whether the mixture is of concern for toxicity and if so whether this is driven by one substance or multiple substances. Analysis was undertaken on monitoring data of four European indoor studies (giving five datasets), involving 1800 records of indoor air or personal exposure. Only one study included data on 2-butoxyethanol.

Results and discussion

Any other information on results incl. tables

Measurements of 2 -butoxyethanol were reported in the EXPOLIS data base as follows:

  • Personal measurements (Helsinki, Athens, Prague, Oxford, Basel): average concentrations: 6.6µg/m³, 70% of measurements below limit of reporting.
  • Indoor residential (Helsinki, Athens, Prague, Milan, Oxford, Basel): average concentrations: 11µg/m³, 63% of measurements below limit of reporting.

Applicant's summary and conclusion

Executive summary:

A secondary source of information reported the results of two indoor air quality studies that detected 2 -butoxyethanol in residential homes at concentrations in the range 6.6 -11µg/m³. It was only detected however in around one third of homes. the original source of information was not checked.
