- Executive summary:
The skin irritation potential of the test substance was determined in vivo according to the EPA OPP 81-5 test guideline and GLP principles. 0.5 g moistened test substance was administered to the shaved back of 3 male and 3 female adult albino rabbits (Hra: New-Zealand White SPF) for 4 hours under semi-occlusive conditions. After 4 hours the test item was removed using tap water and disposable paper towels. Scoring was performed at 0, 24, 48 and 72 hours after application according to the Draize system. No erythema or Oedema reactions were observed (the average of the 24-, 48- and 72-hour scores is 0.0). Therefore the test substance is considered to be not irritating to the skin.

- Irritant / corrosive response data:

Also observed was slight to moderate conjunctival irritation, but no corneal changes. In group 1 the conjunctiva reactions cleared by 96 hours, and in group 2 by 48 hours after instillation. An overview of the data of group 1 can be found in 'any other information on results incl. tables'. Group 2 data is not considered in the final conclusion.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- This GLP compliant EPA 81-4 study in New-Zealand White rabbits, the averages over 72 hours did not reach irritative thresholds for cornea opacity (score 0), iris (score 0), conjunctivae (score <2) and chemosis (score <2)
- Executive summary:
The primary eye irritation potential of the test substance was evaluated according to US EPA test guideline 81-4 and GLP principles. 0.03 g (100 μL) of test substance was instilled into the eyes of nine New-Zealand White rabbits, six of which received a washout 24 hours after instillation (Group 1) and three of which received a washout 30 seconds after instillation (Group 2). The left eye served as untreated control. In both conditions the test material produced iridal involvement and slight to moderate conjunctival irritation. Under the conditions of the study, no cornea opacity was observed. Slight iris reactions were seen 1 hour after instillation but iris was normal at the 24 hours scoring. Moderate conjunctival redness (score 2) was observed up to 48 hours after instillation but was normal 96 hours post instillation. Moderate conjunctival chemosis (score 1) was observed up to 24 hours after instillation but was normal 48 hours post instillation. Mean scores (24-72 hours) were 1.2 for conjunctival redness (no individual mean ≥ 2) and 0.3 for conjunctival chemosis (no individual mean ≥ 2). The eyes of the Group 1 animals cleared of irritation by 96 hours after instillation. The eyes of the rabbits in Group 2 cleared of irritation by 48 hours after instillation. Based on these results, the substance is considered to be not irritating to the eyes.

Additional information
Skin irritation
The skin irritation potential of the test substance was determined in vivo according to the EPA OPP 81-5 test guideline and GLP principles (Glaza, 1991). 0.5 g moistened test substance was administered to the shaved back of 3 male and 3 female adult albino rabbits (Hra: New-Zealand White SPF) for 4 hours under semi-occlusive conditions. After 4 hours the test item was removed using tap water and disposable paper towels. Scoring was performed at 0, 24, 48 and 72 hours after application according to the Draize system. No erythema or oedema reactions were observed (the average of the 24-, 48- and 72-hour scores is 0.0). Therefore the test substance is considered to be not irritating to the skin.
Eye irritation
The primary eye irritation potential of the test substance was evaluated according to US EPA test guideline 81-4 and GLP principles (Glaza, 1991). 0.03 g (100 μL) of test substance was instilled into the eyes of nine New-Zealand White rabbits, six of which received a washout 24 hours after instillation (Group 1) and three of which received a washout 30 seconds after instillation (Group 2). The left eye served as untreated control. In both conditions the test material produced iridal involvement and slight to moderate conjunctival irritation. Under the conditions of the study, no cornea opacity was observed. Slight iris reactions were seen 1 hour after instillation but iris was normal at the 24 hours scoring. Moderate conjunctival redness (score 2) was observed up to 48 hours after instillation but was normal 96 hours post instillation. Moderate conjunctival chemosis (score 1) was observed up to 24 hours after instillation but was normal 48 hours post instillation. Mean scores (24-72 hours) were 1.2 for conjunctival redness (no individual mean ≥ 2) and 0.3 for conjunctival chemosis (no individual mean ≥ 2). The eyes of the Group 1 animals cleared of irritation by 96 hours after instillation. The eyes of the rabbits in Group 2 cleared of irritation by 48 hours after instillation. Based on these results, the substance is considered to be not irritating to the eyes.
Justification for classification or non-classification
Based on the available information, classification for skin and eye irritation is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
