Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
No classification is warranted.
Executive summary:

Tetraglyme was tested for its eye irritant properties equivalent to OECD Guideline 405. At 24 hours after application, clear colorless discharge and conjunctical hyperemia blood vessel were observed in one animal.The other two animals did not show any effects.

Under the conditions of this test, the test item was valued as "non irritant" according to the criteria laid down in the EU Dangerous Substances Directive (67/548/EEC) and in the EU Classification Labelling and Packaging Regulation (1272/2008/EC).
