Details on study design:
Treatment
Approximately 24 hours before the test, the rabbits’ backs and flanks were shorn using electric
clippers equipped with a fine comb, so as to expose an area of skin about 6 cm2.
The test item was applied, as supplied, at a dose of 0.5 mL, on an undamaged skin area of one flank of
each animal, during 4 hours. The patch was secured in position with a strip of surgical adhesive tape.
After the removal of the patch, the treated area was rinsed with distilled water.
On the opposite flank an untreated area was served as the control.
Initially, a single animal was treated. After consideration of the cutaneous responses produced in the
first treated animal, two additional animals were treated.

Grading of reactions
The skin reactions were appreciated 1 hour and then 24, 48 and 72 hours after removal of the patch.

Irritant / corrosive response data:
The results obtained, under these experimental conditions, enable to conclude that the test item
LCE07106, according to the scales of interpretation retained:
- is non irritant to skin (PSi = 0) according to the classification established in the Journal Officiel de
la République Française dated February 21st, 1982,
- and, must not be classified, according to the criteria for classification, packaging and labelling of
dangerous substances and preparations in compliance with the E.E.C. Directives 67/548, 2001/59 and
99/45. No symbol and risk phrase are required.
In accordance with the Globally Harmonized System (COM(2007)355 final), the test item must not be
classified in category 2 “irritant”. No signal word and hazard statement are required.

It was noted, 1 hour after the test item application, on the treated area, a very slight erythema associated with a very slight oedema in two animals. The oedematous reactions were totally reversible at D1 and the erythematous reactions were totally reversible at D2.

Interpretation of results:
GHS criteria not met
Conclusions:
The results obtained, under these experimental conditions, enable to conclude that the test item
LCE07106, according to the scales of interpretation retained:

Executive summary:

The test item LCE07106 was applied, as supplied, at the dose of 0.5 mL, under semi-occlusive

dressing during 4 hours on an undamaged skin area of three rabbits. The experimental protocol was

established from the O.E.C.D. guideline n° 404 dated April 24th, 2002 and the test method B.4 of the

directive n° 2004/73/EC.

It was noted, 1 hour after the test item application, on the treated area, a very slight erythema

associated with a very slight oedema in two animals. The oedematous reactions were totally reversible

at D1 and the erythematous reactions were totally reversible at D2.

The results obtained, under these experimental conditions, enable to conclude that the test item

LCE07106 must not be classified, according to the criteria for classification, packaging and labelling

of dangerous substances and preparations in compliance with the E.E.C. Directives 67/548, 2001/59

and 99/45. No symbol and risk phrase are required.

Irritant / corrosive response data:
Taking into account the irreversibility of the reactions, the test item must be classified R41 "Risk of serious damage to eyes", in accordance with the
European regulation.

The ocular reactions observed during the study have been moderate and partially reversible:

- at the conjunctivae level: a moderate redness, registered 1 hour after the test item instillation and

totally reversible at D17, associated with a moderate chemosis, registered 1 hour after the test item

instillation and totally reversible at D7,

- at the corneal level: a moderate opacity, registered 1 hour after the test item instillation, and still

noted at the end of the observation time (moderate intensity),

- at the iris level: a congestion noted between D1 and D3.

Interpretation of results:
Category 1 (irreversible effects on the eye) based on GHS criteria
Conclusions:
The results obtained, under these experimental conditions, enable to conclude that the test item
LCE07106:
- is highly irritant for the eye (Max. O.I = 59) according to the classification established in the
Journal Officiel de la République Française dated July 10th, 1992.
- and, must be classified R41 "Risk of serious damage to eyes" taking into account the
irreversibility of the reactions, according to the criteria for the classification, packaging and labelling
of dangerous substances in compliance with the E.E.C. Directive n° 67/548, 2001/59 and 99/45. It
must be characterised by the symbol “Xi” and the danger label “irritant”.
In accordance with the Globally Harmonized System (COM(2007)355 final), the test item must be
classified in category 1 “Irreversible effects on the eye”. The signal word “Danger” and hazard
statement H318 “Causes serious eye damage” are required.
Executive summary:

The test item LCE07106 was instilled as supplied, at the dose of 0.1 mL into the eye of one New

Zealand rabbit. The experimental protocol was established on the basis of the official method as

defined in the O.E.C.D. guideline n° 405 dated April 24th, 2002 and the test method B.5 of the

directive 2004/73/EC.

The ocular reactions observed during the study have been moderate and partially reversible:

- at the conjunctivae level: a moderate redness, registered 1 hour after the test item instillation and

totally reversible at D17, associated with a moderate chemosis, registered 1 hour after the test item

instillation and totally reversible at D7,

- at the corneal level: a moderate opacity, registered 1 hour after the test item instillation, and still

noted at the end of the observation time (moderate intensity),

- at the iris level: a congestion noted between D1 and D3.

In conclusion, the result obtained, under these experimental conditions, enable to conclude that the test

item LCE07106 must be classified R41 "Risk of serious damage to eyes" taking into account the

irreversibility of the reactions, according to the criteria for the classification, packaging and labelling

of dangerous substances in compliance with the E.E.C. Directive n° 67/548, 2001/59 and 99/45. It
