TEST SITE
- Preparation: about 24h before the start of the study the skin on the flanks of 6 rabbits was depilated on both sides of the body on an area of approximately 8 x 8 cm using electric
clippers. The skin on the right flank at the test patch application site was additionally scarified using a scarifier.
- Area of exposure: 2.5 x 2.5 cm, covered with medical gauze and indifferent, impermeable PVC foils (5 x 5 cm)
- Type of wrap if used: Eloflex as elastic bandage


REMOVAL OF TEST SUBSTANCE
- Time after start of exposure: 24 hours

Irritant / corrosive response data:
No signs of systemic toxicity were observed during the observation period
Interpretation of results:
GHS criteria not met
Conclusions:
In the experimental conditions the test item is detemined to be not irritating to the skin.
Executive summary:

In the primary skin irritation test according to the Code of Federal Regulations, Title 16, Section 1500.41 the test item produced a primary irritation score of about 0.3. Due to substance-related coloration of the skin slight erythema could not be detected if apparent. Thus, the product is assassed to be non-irritant to the skin.

no adverse effect observed (not irritating)

Evaluation
Evaluation covered pathological findings in the cornea (degree of opacity and area •affected), iris and conjunctivae (reddening, swelling and discharge). Evaluation details were based on the key given below, which was used to determine the irritation score.

Interpretation of results:
GHS criteria not met
Conclusions:
Testing for primary eye irritation in the rabbit showed that the substance is not irritating to eyes.
Executive summary:

100 µL of the test item was applied once to the conjunctival sac of the left eye of three rabbits. The untreated eyes served in each case as a control.

The treated eyes were examined 24, 48 and 72 hours and 8 days after application of the test substance.

At 8 days the eyes were also examined for corneal lesions under UV light after instillation of one drop of fluorescein.

No irritant effects were observed, hence the test substance is considered to be not irritating to the eye.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Respiratory irritation
