Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
BASF-Test: Before OECD Guideline 405 was established, eye irritation was tested using an internal method (BASF test). White Vienna rabbits were used. One drop of the test substance was applied to the conjunctival sac of the right eye of the animal. The adjacent eye was treated with one drop of physiological solution of sodium chloride and served as a control.The animals were observed several times on the treatment day and 8 days afterwards, and findings were recorded on working days.
GLP compliance:
no

Results and discussion

In vivo

Results
Irritation parameter:
overall irritation score
Time point:
other: immediately after treatment
Score:
> 4
Reversibility:
not reversible
Remarks on result:
other: Observation of eyes revealed inmmediate corrosion after treatment
Irritant / corrosive response data:
One drop of indiluted Acrylic acid caused a severe corrosion of the conjunctiva and cornea as a result of an exposure period of 10 minutes. In the course of 8 to 14 days, a complete destruction of the eye was observed and the animal was sacrificed.

Applicant's summary and conclusion

Interpretation of results:
Category 1 (irreversible effects on the eye) based on GHS criteria
