- 2-(2-ethoxyethoxy)ethanol
- Cas Number:
- 111-90-0
- Molecular formula:
- C6H14O3

- 2-(2-ethoxyethoxy)ethan-1-ol
- Details on test material:
- - Name of test material (as cited in study report): Ethyldiglykol
Constituent 1
- Specific details on test material used for the study:
- Product in a cleaner
Method
- Type of population:
- occupational
- Ethical approval:
- not applicable
- Details on study design:
- Personal air samples were collected in 12 cleaning companies, and analyzed by conventional methods. Study region was French speaking cantons in Switzerland. 450 companies cleaning companies approached, 52 agreed to participate and of these 12 were recruited for the study. 2-4 workers were used for sampling observations per website. During sampling, workers were asked not to smoke.
Presence of DEGEE was confirmed by listing in safety data sheet. - Exposure assessment:
- measured
- Details on exposure:
- Tasks were categorised for analysis and sampling took place from the start to the finishe of the cleaning task. Task categories were intensive floor cleaning, apartment cleaning, industrial cleaning, public space cleaning and patient room cleaning. Tasks can be considered as 'professional' rather than 'industrial'.
Sampling was using backpack containing air sampling pumps operating at 0.18L/min. Exposure determinants were: spray/non-spray, concentration in cleaner, ventilation level (cross ventilation, general ventilation, no ventilation) and room size (small, medium, large, very large). - Statistical methods:
- geometric mean and standard deviation
Results and discussion
- Results:
- MEASUREMENTS WHEN DEGEE KNOWN TO BE PRESENT FROM DATASHEET
Sampling duration :38-274 mins
29 measurement, 14% below LOD (0.034mg/m3)
GM: 0.053mg/m3, GSD: 7.0, range 0.011 - 0.877mg/m3.
MEASUREMENTS WHEN DEGEE NOT KNOWN TO BE PRESENT FROM DATASHEET
Sampling duration :30-220 mins
68 measurement, 75% below LOD (0.029mg/m3)
GM: 0.005mg/m3, GSD: 8.4, range 0.009 - 0.983mg/m3.
MEASUREMENTS BY ACTIVITY
Intensive floor cleaning: n=6 (33% below LOD) GM: 0.083mg/m3, GSD: 10.1.
Apartment cleaning: n=3 (none below LOD) GM: 0.019mg/m3, GSD: 1.4.
Applicant's summary and conclusion
- Executive summary:
A study of professional cleaners in Switzerland found that they were exposed to diethylene glycol ethyl ether during the use of cleaning compounds containing the solvent but that concentrations were well below those of concern. The highest concentrations observed were below 1mg/m3 with average values well below this. The highest exposures came during the use of intensive floor cleaning operations using stripping solutions.
