Description of key information

Acute Oral Toxicity

NECTARYL was tested to evaluate the acute toxicity following a single oral administration (limit test) in rats according to the Guideline No. 401 in 1989.

From the results obtained under the experimental conditions employed, the LD0 by oral route, in the rat, of the test substance administered once only, as supplied, is greater than or equal to 2008 mg/kg.

Acute Dermal Toxicity

NECTARYL was tested to evaluate the acute toxicity following a single dermal administration (limit test) in rats according to the Guideline No. 402 in 1989.

From the results obtained under the experimental conditions employed, the LD0 by dermal route, in the rat, of the test substance administered once only, as supplied, is greater than or equal to 2008 mg/kg.

Mortality and abnormal clinical signs were noted 15 minutes after intubation, and 1, 2 and 4 hours,and then daily for the 14day study period.

All animals were weighed the day before treatment (Day-1), immediately before administration of the test substance (Day1), on Days 8 and 15.

A necropsy was performed for all the animals after the 14day study period and the final observation (Day15).

There were no effect of treatment in any of the parameters examined.

From the results obtained under the experimental conditions employed, the LD0 by oral route, in the rat, of the test substance administered once only, as supplied, is greater than or equal to 2008 mg/kg.

Acute toxicity: via inhalation route

Reference
Endpoint:
acute toxicity: inhalation
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size

no study available

Type of coverage:
semiocclusive
Vehicle:
unchanged (no vehicle)
Remarks:
test substance as supplied
Details on dermal exposure:
The test substance was spread over an area of approximately 10 % of the total body surface area. It was applied uniformly using a finger covered by a very fine natural latex glove and to ensure penetration of all the substance or of the maximum possible quantity the area was lightly massaged for approximately 15 seconds.
The test substance was kept in contact with the skin by means a semi­ occlusive dressing composed of a perforated adhesive band (Peloplast) 10 cm wide, applied onto an elastic crepe bandage (Creplux / Molinier) covering the entire shaved area to avoid any possible orthoergic reactions and encircling the trunk of the animal without interfering with the abdominal and respiratory movements of the animal. This dressing entirely covered the treated area to avoid ingestion of the test substance by the animals.
Duration of exposure:
24 hour period
Doses:
2008 mg/kg
No. of animals per sex per dose:
A single dose was applied to a group of rats composed of 5 males and 5 females.
Control animals:
no
Details on study design:
Reason for the choice of the dose level : no deaths were seen at a dose level of 2008 mg/kg during the preliminary study.
Since the absence of mortality was confirmed after the 14 day observation period, no other dose level was applied and the study was considered completed.

Preliminary study:
No deaths were seen at a dose level of 2008 mg/kg during the preliminary study.

Clinical evaluations were performed 15 minutes after application, at 1, 2, and 4 hours, then daily for 14 days. There were no treatment related deaths during the study. A necropsy was performed on all animals after the 14 day study period. There were no clinical pathological signs noted. The study concluded that the cutaneous LD0 for Nectaryl in rats was equal to or greater than 2008 mg/kg.

LD50 dermal > 2008mg/kg, no mortalities or pathological clinical signs.

Justification for classification or non-classification

Based on the data available and key results described in this summary, the substance has shown no acute toxicity potential and should therefore not be classified for Acute oral and dermal toxicity according to the (EC) No 1272/2008 Regulation (CLP).
