Endpoint summary

Description of key information

Acute oral toxicity was assessed in the rat using the Acute Toxic Class Method. The oral LD50 value of F-2200HM in Wistar rats was established to exceed 2000mg/kg body weight. Acute inhalation toxicity was waived as inhalation is unlikely due to the low vapour pressure of F-2200HM. Acute dermal toxicity was assessed in the rat. The acute dermal median lethal dose (LD50) of the test item in the Wistar strain rat was found to be greater than 2000mg/kg bodyweight. No deaths occured in the dermal and oral acute studies.

Conclusions:

The oral LD50 value of F-2200HM in Wistar rats was established to exceed 2000mg/kg body weight.

Executive summary:

Assessment of acute oral toxicity with F-2200HM in the rat (Acute Toxic Class Method).

The study was carried out based on the guideline described in: EC Commission Directive 96/54/EC, Part B.1 tris 'Acute Oral, Acute Toxic Class method' and OECD no. 423, "Acute Oral Toxicity - Acute Toxic Class Method".

F-2200HM was administered by oral gavage to three Wistar rats of each sex at 2000mg/kg bw. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (day 15).

No mortality occured.

Lethargy and uncoordinated movements were noted in all animals on day 1 and in addition hunched posture was noted in all females on day 2.

The body weight gain shown by the animals over the study period was considered to be normal.

No abnormalities were found at macroscopic post mortem examination of the animals.

The oral LD50 value of F-2200HM in wistar rats was established to exceed 2000mg/kg bw.

Based on these results and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations (Guidelines in Commision Directive 93/21/EEC), F-2200HM does not have to be classified and has no obligatory labelling requirement for oral toxicity.

Executive summary:

Introduction: The study was performed to assess the acute dermal toxicity of the test item in the Wistar strain rat. The method was designed to be compatible with the following: OECD 402, B3 EC, EPA OPPTS 870.1200

Method: A group of ten animals (five males and 5 females) was given a single, 24 hour, semi-occluded dermal application of the test item to intact skin at a dose levelof 2000mg/kg bodyweight. Clinical signs and bidyweight development were monitored during the study. All animals were subjected to gross necropsy.

Mortality: there were no deaths

Clinical observations: no signs of systemic toxicity

Dermal irritation: Signs of dermal irritation noted were very slight erythema, haemmorrhage of dermal cappilaries, small superficail scattered scabs, hardened light brown coloured scabs, glossy skin and scab lifting to reveal glossy skin. There were no signs of dermal irritation noted at the test site of one male.

Bodyweight: Animals showed expected gains in bodyweight over the study period, except for one female which showed bodyweight loss during the first week but expected gain in bodyweight during the second week.

Necropsy: No abnormalities were noted

Conlusion: The acute dermal median lethal dose (LD50) of the test item in the Wistar strain rat was found to be greater than 2000mg/kg bw
