Test material

Constituent 1
Chemical structure
Reference substance name:
Reaction mass of (1-methylethylidene)bis(4,1-phenyleneoxy-2,1-ethanediyl) bismethacrylate and 2-{4-[2-(4-{2-[2-(methacryloyloxy)ethoxy]ethoxy}phenyl)propan-2-yl]phenoxy}ethyl methacrylate

939-702-5
Molecular formula:
C23H24O4 (C2H4O)n
IUPAC Name:
Reaction mass of (1-methylethylidene)bis(4,1-phenyleneoxy-2,1-ethanediyl) bismethacrylate and 2-{4-[2-(4-{2-[2-(methacryloyloxy)ethoxy]ethoxy}phenyl)propan-2-yl]phenoxy}ethyl methacrylate
Test material form:
liquid: viscous

Test animals / tissue source

Species:
rabbit
Strain:
New Zealand White
Details on test animals or tissues and environmental conditions:
Healthy adult rabbits.

Test system

Vehicle:
unchanged (no vehicle)
Controls:
other: the other eye remaining untreated serves as a control
Amount / concentration applied:
One tenth of a milliliter of the test substance is allowed to fall on the overted lower lid of one eye of each rabbit; the upper and lower eye lid are then cared fully closed and subsequently held together for as least one second before releasing, to prevent loss of material.
Duration of treatment / exposure:
one administration
Observation period (in vivo):
24-48-72 hours and 7 fays after instillation of the test material.
Number of animals or in vitro replicates:
6
Details on study design:
The eyes are not washed following instillation and the animals are released immediately.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Remarks:
Not eye irritating
Conclusions:
2 moles Ethoxylated bisphenol A methacrylate did not elicit any detectable eye lesions; it is considered to be not irritating for eyes.
Executive summary:

2 moles Ethoxylated bisphenol A methacrylate was examined for eye skin irritating properties according to the Draize method.

0.1 mL of the test substance is allowed to fall on the eye. The eyes are not washed following instillation and the animals are released immediately. The eyes are examined at 24, 48, 72 hours and 7 fays after instillation of the test material.

2 moles Ethoxylated bisphenol A methacrylate did not elicit any detectable eye lesions; it is considered to be not irritating for eyes.
