- Interpretation of results:

- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Vetivert oil Haïti has a mildly irritating effect on rabbit's eyes. This effect is totally reversible within 10 days after exposure, under the conditions of the study. Based on the results in this study and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations (Guidelines in Commission Directive 93/21/EEC), Vetivert oil Haiti is classified as irritating to eyes.
- Executive summary:
0.1 ml of Vetivert oil was instilled into the right eye of 6 young albino type rabbits. The untreated left eye served as a control. Draize scoring of both eyes was conducted at 24, 48, and 72 hours and at days 4 and 7. Fluorescein staining was conducted at 24 hours and day 7 on both eyes. Any persistent changes observed on Day 7 were re-evaluated on Day 10 using a hand held ophthalmoscope and the fluorescein method. Classification of the relative irritancy was made according to the following scale, utilizing the highest reading obtained at 24, 48 or 72 hours after instillation of the test material. Reactions were considered as non-irritating with scores of 0.0 to 0.5; practically non-irritating at 0.6 to 10.0; mildly irritating at 10.0 to 25.0; moderately irritating at 25.1 to 50.0; and extremely irritating at score of 50.1 to 110.
Under the conditions of the study, 0.1 ml of 100% test material instilled into the right eye of each of six animals was mildly irritating, causing slight iritis and corneal opacity. The mean ocular irritation score was 19.0/110 at 24 hours.
Based on these results and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations (Guidelines in Commission Directive 93/21/EEC), Vetivert oil Haiti is classified as irritating to eyes.

Additional information
Skin irritation
Based on the criteria outlined in Annex VII of REACH, an in vitro skin corrosion or irritation test does not need to be performed when available information indicates a classification for eye irritation or skin corrosion. A Draize test (Springer, 1980) is available and indicates that Vetiver oil needs to be classified as an eye irritant. Subsequently, the available acute dermal toxicity test with Vetiver bourbon (Moreno, 1973) and the guinea pig maximisation test with Vetyver Oil Haïti (Quest, 1983) indicate a skin irritating potential of the submission substance. Therefore, it is not needed to conduct an additional skin irritation or corrosion test and vetiver oil should be classified for this endpoint accordingly.
Eye irritation
In an eye irritation study which was performed based on the procedure by Draize, H.J. "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics", Assoc. of Food and Drug Officials of the U.S., Austin, Texas (1959), 0.1 ml of Vetiver oil was instilled into the right eye of 6 young albino type rabbits. The untreated left eye served as a control. Draize scoring of both eyes was conducted at 24, 48, and 72 hours and at days 4 and 7. Fluorescein staining was conducted at 24 hours and day 7 on both eyes. Any persistent changes observed on Day 7 were re-evaluated on Day 10 using a hand held ophthalmoscope and the fluorescein method. Classification of the relative irritancy was made according to the following scale, utilizing the highest reading obtained at 24, 48 or 72 hours after instillation of the test material. Reactions were considered as non-irritating with scores of 0.0 to 0.5; practically non-irritating at 0.6 to 10.0; mildly irritating at 10.0 to 25.0; moderately irritating at 25.1 to 50.0; and extremely irritating at score of 50.1 to 110.
Under the conditions of the study, 0.1 ml of 100% test material instilled into the right eye of each of six animals was mildly irritating, causing slight iritis and corneal opacity. The mean ocular irritation score was 19.0/110 at 24 hours. Based on these results and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations (Guidelines in Commission Directive 93/21/EEC), Vetivert oil Haiti is classified as irritating to eyes.
Justification for selection of eye irritation endpoint:
The selected study is the key and only study for this endpoint.
Effects on skin irritation/corrosion: irritating
Effects on eye irritation: irritating
Justification for classification or non-classification
Based on the available information, Vetiver oil should be classified as irritating to skin and eyes in accordance with the criteria outlined in Annex I of 1272/2008/EC (CLP) and Annex VI of 67/548/EEC (DSD).
