Details on test animals or tissues and environmental conditions:

TEST ANIMALS
- Source: Manfred Bauer Kaninchen, Lohe 7/1, 74632 Neuenstein,Germany
- Age at study initiation: Approx. 7.5 - 8.5 months
- Weight at study initiation: 4.2 - 4.8 kg
- Housing: For 8 hours following test item application, the animals were kept singly in restrainers which allowed free movement of the head but prevented a complete body turn, wiping of the eyes with the paws and excluded irritation of the eye by excrements and urine.
During the acclimatisation period and after the 8-hour period in restrainers, the animals were kept singly in cages with dimensions of 380 mm x 425 mm x 600 mm (manufacturer: Dipl.Ing. W. EHRET GmbH, 16352 Schönwalde, Germany)
- Diet (e.g. ad libitum): The food was available ad libitum before and after the exposure period.
- Water (e.g. ad libitum): Tap water was offered daily ad libitum.
- Acclimation period: At least 20 adaptation days


ENVIRONMENTAL CONDITIONS
- Temperature (°C): 20°C ± 3°C (maximum range).
- Humidity (%): The relative humidity amounted to 30% - 70% (maximum range).
- Air changes (per hr): 15 to 20 times
- Photoperiod (hrs dark / hrs light): Rooms were lit (150 lux at approx 1.5 m room height) and darkened on a 12-hour light/12-hour dark cycle.


IN-LIFE DATES: From: June 01, 2014 To: June 28, 2014

Vehicle:

unchanged (no vehicle)

Controls:

other: The left eye, which remained untreated, served as a control.

Amount / concentration applied:

TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.1 mL of the test item were administered into one eye. The test item was placed into the conjunctival sac of the right eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second in order to prevent loss of the material. The left eye, which remained untreated, served as a control.
- Concentration (if solution):


VEHICLE
- Amount(s) applied (volume or weight with unit):
- Concentration (if solution):
- Lot/batch no. (if required):
- Purity:

Duration of treatment / exposure:

The test was performed initially using one animal. As no corrosive or severe irritant effects were observed in this animal, 2 further animals were employed 24 hours after start of the initial test.

Observation period (in vivo):

The eyes were examined ophthalmoscopically with a slit lamp prior to the administration and 1, 24, 48, 72 hours and 4 to 9 days after the administration. The eye reactions were observed and registered.

Number of animals or in vitro replicates:

3 female animals

Interpretation of results:

not irritating

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

According to the EC-Commission directive 67/548/EEC and its subsequent amendments on the approximation of the laws, regulations and administrative provision relating to the classification, packaging and labelling of dangerous substances and the results obtained under the present test conditions FlocrylTM ADAM / MC80 was non - irritating to eyes, hence, no labelling is required.
Also, according to the Globally Harmonized System (GHS) and EC-Regulation 1272/2008 and subsequent regulations, the test item is non-irritating to eyes; classification and labelling of the substance is not necessary.

Endpoint conclusion

Endpoint conclusion:

no adverse effect observed (not irritating)

Additional information

The substance was non-irritating to skin in a GLP guideline study (Manciaux, 2002).

A study dating from 1985 by Collier demonstrated eye irritation. However, an in-depth review of the study report revealed several major problems with the study. Furthermore, the test susbstance was not identified and considering the test period, was most probably not a production sample. For these reasons, a new, GLP study has been conducted on a sample with exactly the same substance identity as the registration. This study demonstrated that there was a complete absence of eye irritation.

Justification for classification or non-classification

Substance was non-irritating to skin and eyes in GLP guideline studies.
