Description of key information
Acute toxicity after single oral application was tested in male and female rats, which received up to 10,000 mg/kg bw. No animal died or showed clinical symptoms/macroscopic anomalies. The necropsy did not reveal any effect. The LD50 value for acute oral toxicity was considered to be greater than 10,000 mg/kg bw. Due to the findings described above (LD50 oral in rats greater than 10,000 mg/kg bw) Hostavin 3206 does not have to be classified as acute orally toxic.

Additional information
Based on the results of an oral toxicity study the LD50 value for acute oral toxicity was considered to be greater than 10,000 mg/kg bw.
In accordance with REACH “Column 2” in Annex VIII there is
sufficient weight of evidence from several independent sources of
information leading to the conclusion that Hostavin 3206 does not exert
systemic toxic effects after acute inhalation exposure and thus does not
have to be classified, because
- the LD50 value for acute oral toxicity of Hostavin 3206 is greater
10,000 mg/kg bw,
- Hostavin 3206 does not have to be classified as skin irritating,
- inhalation to consumer is very unlikely to occur, since the substance
is embedded in polymeric matrices for consumer applications and
-inhalation exposure to
workers while manufacturing is also considered to be negligible with
reference to the physical state (viscous liquid) and low volatility (2.8
hPa) of this substance.
Therefore, it is
concluded that testing of acute inhalation toxicity of Hostavin 3206
salt is not scientifically necessary.
It can reasonably be deduced that Hostavin 3206 does not exert systemic toxic effects after dermal application and thus does not have to be classified, because this substance did not cause lethal effects after administration of a single oral dose of up to 10,000 mg/kg bw in rats.Furthermore the substance does not have to be classified as skin irritating. Due to the combination of its polar character (amine and carbonyl function at one end of the molecule) and the long extent of the alkyl chain (at the other end of the molecule) it is unlikely that higher amounts (limit dose of dermal toxicity testing according OECD 402: 2,000 mg/kg bw/d) than tested in the acute oral toxicity study (tested up to 10,000 mg/kg bw/d) will be systemically available via the intact skin barrier even if the most unlikely amount of 100% penetration is assumed. Therefore, testing is not scientifically necessary.
Justification for selection of acute toxicity – oral endpoint
Well performed and reported study equivalent to OECD guideline 401.
Justification for selection of acute toxicity – inhalation endpoint
n.a.
Justification for selection of acute toxicity – dermal endpoint
n.a.
Justification for classification or non-classification
Due to the findings described in the acute oral toxicity study (LD50 oral in rats greater than 10,000 mg/kg bw) Hostavin 3206 does not have to be classified as acute orally toxic. Based on the substance's physico-chemical and non-irritant properties, as well as the unlikeliness of exposures to consumer and workers no higher systemical exposure via inhalation or dermal penetration is expected to occur than that tested in the course of the oral toxicity study. Therefore, Hostavin 3206 does not have to be classified as acute toxic.
