Remarks on result:

other: Moderate erythema followed by drying, cracking, and shedding of the skin was observed.

Irritant / corrosive response data:

- Moderate erythema followed by drying, cracking, and shedding of the skin was observed.

Other effects:

- One animal with abraded skin was died on Day 6.

None

Interpretation of results:

study cannot be used for classification

Conclusions:

Under the test conditions, Juniper Berry Oil induced moderate skin irritation in rabbits.

Executive summary:

In an acute dermal toxicity study (limit test), six albino rabbits (three with intact skin and three with abraded skin) were given a single dermal application of Juniper Berry Oil at 5000 mg/kg bw. Animals were observed for mortality, clinical signs and local reactions daily for 14 days.

 

One animal with abraded skin was died on Day 6. No animal with intact skin died. Moderate erythema followed by drying, cracking, and shedding of the skin was observed. In this study, the acute dermal LD50 of Juniper Berry Oil was higher than 5000 mg/kg bw in albino rabbits.

 

Under the test conditions, juniper berry oil induced moderate skin irritation in rabbits.

This study was conducted according to a non-standard method and adequate scoring of skin effects was not provided, therefore it was not possible to take a decision on the classification based solely on this study.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Under the test conditions, oral LD50 of JUNIPER BERRY OIL is higher than 5000 mg/kg bw in rats therefore it is not classified according to the criteria of the Annex I of the Regulation (EC) No. 1272/2008 (CLP) and to the GHS.

Executive summary:

In an acute oral toxicity study (limit test), groups of Sherman-Wistar rats (5/sex/dose) were given a single oral dose of JUNIPER BERRY OIL at 5000 mg/kg bw. Animals were then observed for mortality and clinical signs daily for 14 days.

Prostration, coma, and death following dose administration was observed in 1/5 female animal on Day 2. No mortality was observed in males. All survivors showed morbidity (lethargic) and full recovery at 48 h.

In this study, the oral LD50 of JUNIPER BERRY OIL was higher than 5000 mg/kg bw in rats.

 

Under the test conditions, oral LD50 of JUNIPER BERRY OIL is higher than 5000 mg/kg bw in rats therefore it is not classified according to the annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.

This study is considered as acceptable and satisfies the requirement for acute oral toxicity endpoint.
