DSD: not classified - Executive summary:
Dermal sensitisation has been investigated in the guinea pig using the maximisation test of Magnusson and Kligman. No evidence of sensitisation to the substance was noted.
Reference
Body weights and body weight gain were comparable to the control group during the study.
Local reactions after induction:
- Intradermal: One hour after intradermal induction, all FCA-treated animals showed erythema and edema at the site of injection. After 24 h additional necrosis was seen. Erythema were seen at the other injection sites after 1 and 24 h.
- Epidermal: All test and control animals showed erythema and edema at the application site after 1 h, including bloody inflammation of all FCA-treated injection sites as well as agitation and scratching. After 24 h erythema and edema and incrustation of the inflammation sites were still present in all animals.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
Skin sensitisation
One study, investigating the skin sensitising properties of 2-(2-ethoxyethoxy)ethyl acetate is available. The study was conducted according to OECD 406 (Mürmann, 1990). Female guinea pigs (20 in test group, 10 in control group) were induced with a single intradermal injection of the test substance at 0.5% in water and an epicutaneous occlusive application of the test substance at 100% on the shoulder region 7 days later. A negative control group of 20 animals was treated with water only. Epicutaneous challenge exposure was conducted 21 days after the first induction for 24 h under occlusive conditions at concentrations of 100% of the test substance.
After challenge, all test and control animals showed no skin reactions after 24 and 48 h. In summary, 2-(2-ethoxyethoxy)ethyl acetate (CAS 112-15-2) was considered as not sensitising.
Conclusion for sensitisation
No skin sensitisation properties of 2-(2-ethoxyethoxy)ethyl acetate (CAS 112-15-2) were apparent in the available in vivo study.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
The available data on skin sensitisation properties of 2-(2-ethoxyethoxy)ethyl acetate (CAS 112-15-2) do not meet the criteria for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and the data are therefore conclusive but not sufficient for classification.
