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
Test material
- Reference substance name:
- Acrylic acid
- EC Number:
- 201-177-9
- EC Name:
- Acrylic acid
- Cas Number:
- 79-10-7
- Molecular formula:
- C3H4O2
- IUPAC Name:
- prop-2-enoic acid
Constituent 1
- Specific details on test material used for the study:
- - Name of test material (as cited in study report): Acrylic acid, raw, stabilised with approx. 0.2% phenothiazon.
- Analytical purity: 86%
- Composition of test material, percentage of components: Acrylic acid 86%, 2-propenoic acid, 2-carboxylethyl ester, 11%, water 2%,
phenothiazon 0.2%, unknown components 0.8%.

Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The adjacent eye was treated with one drop of physiological solution of sodium chloride and served as a control.
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied: approx. 50 µL
- Duration of treatment / exposure:
- 21 days
- Observation period (in vivo):
- 21 days
- Number of animals or in vitro replicates:
- 2
- Details on study design:
- REMOVAL OF TEST SUBSTANCE

SCORING SYSTEM: The original BASF grading was converted into the numerical grading according to the OECD Draize system.
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
