Conclusions:

The test material produced only minimal transient irritation.

Executive summary:

The skin irritant potential of the test item GM102E was investigated in a test performed on New Zealand White rabbits according to the Draize method. 

200 mg of test item was applied during 8 hours on the dorsal area of 6 animals with an occlusive coverage. The effects were observed during 3 days after application.

Very slight erythema reactions were observed on several rabbits but these reactions were reversible within the end of the observation period (3 days). Thus the substance is considered as a very slight skin irritant.

Based on these results and according to the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP), GM102E should not be classified for skin irritation.

Irritant / corrosive response data:

Reversibility of any observed effect: Changes not fully reversible within 1 day
The study was terminated after 24 hours following observations of severe effects in 2 rabbits. No further animals were treated.

Other effects:

The ocular lesions reached the maximum for each paramater within 24 h after the administration of the substance. The lesions caused severe damage to the eyes and the animals were humanly sacrificed due to poor conditions.
Rinsing the eyes within 30 seconds after application (1 animal) did not produce significant changes in the severity of the effects.

Interpretation of results:

Category 1 (irreversible effects on the eye)

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

Severe ocular effects were observed within 2 to 24 hours after treatment. The study was terminated.

Executive summary:

The eye irritant potential of the test item GM102E was investigated in a test performed on New Zealand White rabbits according to the Draize method. 

100 mg of test item was applied during 30 secondes before washing. The effects were intended to be observed during 7 days after application.

The study was terminated after 24 hours following observations of severe effects in 2 rabbits. No further animals were treated.

The ocular lesions reached the maximum for each parameter within 24 h after the administration of the substance. The lesions caused severe damage to the eyes and the animals were humanly sacrificed due to poor conditions.

Rinsing the eyes within 30 seconds after application (1 animal) did not produce significant changes in the severity of the effects.

Based on these results and according to the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP), GM102E should be classified for serious eye damage (Eye dam. Category 1, H318).

Additional information

Skin corrosion/irritation:

The skin irritant potential of the test item GM102E was investigated in a test performed on New Zealand White rabbits according to the Draize method. 

200 mg of test item was applied during 8 hours on the dorsal area of 6 animals with an occlusive coverage. The effects were observed during 3 days after application.

Very slight erythema reactions were observed on several rabbits but these reactions were reversible within the end of the observation period (3 days). Thus the substance is considered as a very slight skin irritant.

Based on these results and according to the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP), GM102E should not be classified for skin irritation.

Eye corrosion/irritation:

The eye irritant potential of the test item GM102E was investigated in a test performed on New Zealand White rabbits according to the Draize method. 

100 mg of test item was applied during 30 secondes before washing. The effects were intended to be observed during 7 days after application.

The study was terminated after 24 hours following observations of severe effects in 2 rabbits. No further animals were treated.

The ocular lesions reached the maximum for each parameter within 24 h after the administration of the substance. The lesions caused severe damage to the eyes and the animals were humanly sacrificed due to poor conditions.

Rinsing the eyes within 30 seconds after application (1 animal) did not produce significant changes in the severity of the effects.

Based on these results and according to the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP), GM102E should be classified for serious eye damage (Eye dam. Category 1, H318).

Justification for selection of skin irritation / corrosion endpoint:
Only one reliable study available.

Justification for selection of eye irritation endpoint:
Only one reliable study available.

Effects on eye irritation: corrosive

Justification for classification or non-classification

The test material appears to have very slight skin irritation effects in in vivo studies with rabbits. Thus, GM102E is not classified for skin irritation according to Regulation (EC) 1272/2008 (CLP).

GM102E caused severe damage to eyes in a Draize test on rabbits and thus the test item is classified as Eye Dam. 1 (H318) according to Regulation (EC) 1272/2008 (CLP).
