Description of key information
The acute toxicity: oral of the test substance was determined during a GLP study performed in accordance with the OECD Guideline for Testing of Chemicals 423.
Three female Sprague-Dawley rats were treated at 2000 mg/kg bw. Following this treatment, three male and three female rats received 200 mg/kg bw. Clinical signs and body weight development were monitored for 14 days following the administration of the test substance. All animals were subjected to gross necropsy.
All animals treated with 2000 mg/kg bw and one female treated with 200 mg/kg were found dead during the day of dosing. Common signs of systemic toxicity noted in animals treated with 2000 mg/kg bw were hunched posture, ataxia, loss of righting reflex, decreased respiratory rate, laboured respiration, coma and pallor of the extremities. Common signs of systemic toxicity noted in animals treated with 200 mg/kg bw were hunched posture and lethargy with incidents or isolated incidents of diarrhoea, ataxia, decreased respiratory rate, laboured respiration and noisy respiration. Surviving animals showed expected gains in bodyweight over the study period and recovered one day after dosing.
The acute oral median lethal dose (LD50) of the test item in rats was concluded to be 200 mg/kg body weight. As the majority of LD50 range falls into Acute Tox. Oral, Category 4 and the mean LD50 value would lie between 300 and 500 mg/kg bw, classification into category 4 was deemed applicable in accordance with Table 3.1.1 of Regulation (EC) No.1272/2008.
No exposure of humans to the registered substance via inhalation is expected. Therefore it is not appropriate to perform testing on the substance by the inhalation, in accordance with Annex VIII of REACH, Column 2.
The acute toxicity: dermal of the test substance was determined during a GLP study performed in accordance with the OECD Guideline for Testing of Chemicals 402.
Five male and five female Sprague-Dawley rats were exposed to 2000 mg/kg bw of the test substance for 24h. Clinical signs and body weight development were monitored for 14 days following the administration of the test substance. All animals were subjected to gross necropsy.
No deaths were observed. Dermal exposure to the test substance did not induce observable adverse effects.
The acute oral median lethal dose (LD50) of the test item in rats was concluded to be 2000 mg/kg body weight. The test item did not meet the criteria for classification according to Regulation (EC) No.1272/2008 on the Classification, Labelling and Packaging of Substances and Mixtures.

Acute toxicity: via inhalation route
Link to relevant study records
- 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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with Annex VIII of REACH, Column 2, testing by inhalation route is appropriate if exposure of humans via inhalation is likely. Vinyl Chloroacetate is not made available on the EU market as a monomer and is imported already polymerised. Therefore no exposure of humans via inhalation is expected. - Clinical signs:
