Animals were then observed for mortality, clinical signs and bodyweights for 14 days and at the end of the study the surviving animals were sacrificed for macroscopic examination.
The test material was not toxic orally to rats under conditions of this test. The internal organ on superficial examination appeared normal, excep for a deposit of fibrous tissue in the thoracic cavity of one animal.
Oral LD50 Combined > 5000 mg/kg bw.
Under the test conditions, the test material is not classified according to 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.

- Executive summary:
In an acute dermal toxicity, albino rabbits (3/sex, half with abraded skin) were occlusively exposed to undiluted test material at dose of 5000 mg/kg bw for 24 h. The animals were observed for mortality, clinical signs and body weight for 14 days and then necropsied for macroscopic observations.
1/6 animals (1 male, with abraded skin) died. At necropsy, its right lung was filled with yellow-white pus-like substance. No systemic or local effects were obsevred in other animals
Dermal LD50 Combined > 5000 mg/kg bw
Under the test conditions, the test material is not classified according to the Regulation EC No. 1272/2008 (CLP) and to the GHS.

Additional information
Acute toxicity: oral:
A key study was identified (Consumer Product Testing, 1979). This acute oral toxicity study was performed prior to the OECD test guideline No. 401 but the protocol is similar to that guidance.
The test material was not toxic orally to rats under conditions of this test. The internal organ on superficial examination appeared normal, excep for a deposit of fibrous tissue in the thoracic cavity of one animal.
Oral LD50 Combined > 5000 mg/kg bw.
Acute toxicity: dermal:
A key study was identified (Consumer Product Testing, 1979). This acute dermal toxicity study was performed prior to the OECD test guideline No. 402 but the protocol is similar to that guidance with the following exeptions: occlusive dressing (worst-case condition) was used and only 3 animals per sex were included. However, a repeat study under standard conditions is unlikely to show worse effects, therefore this study was considered sufficiently robust to cover this endpoint.
Rabbits were given a single dermal application of the undiluted test material to intact or abraded skin for 24 hours.
1/6 animals (1 male, with abraded skin) died. At necropsy, it's right lung was filled with yellow-white pus-like substance. No systemic or local effects were obsevred in other animals
Dermal LD50 Combined > 5000 mg/kg bw
Justification for classification or non-classification
Harmonised classification:
The substance has no harmonised classification according to the Regulation (EC) No. 1272/2008 (CLP).
Self-classification:
Acute toxicity (Oral):
Based on the available data, the substance is not classified according to the CLP and the GHS as the LD50 is > 5000 mg/kg bw.
Acute toxicity (Dermal):
Based on the available data, the substance is not classified according to the CLP and the GHS as the LD50 is > 5000 mg/kg bw.
Acute toxicity (Inhalation):
No information was available.
Specific target organ toxicity: single exposure (Oral):
The classification criteria according to the CLP and to the GHS as specific target organ toxicant (STOT) – single exposure, oral are not met since no reversible or irreversible adverse health effects were observed immediately or delayed after exposure and no effects were observed at the guidance value (oral) for a Category 1 classification (C≤ 300 mg/kg bw) and at the guidance value (oral) for a Category 2 classification (2000 mg/kg bw≥C > 300 mg/kg bw). No classification is required.
The criteria for Transient Organ effects (STOT-SE Category 3) according to the CLP and to the GHS are not met since narcotic effects were not observed in the acute oral toxicity study.
Specific target organ toxicity: single exposure (Dermal):
The classification criteria according to the CLP and to the GHS as specific target organ toxicant (STOT) – single exposure, dermal are not met since no reversible or irreversible adverse health effects were observed immediately or delayed after exposure and no effects were observed at the guidance value (dermal) for a Category 1 classification (C≤ 1000 mg/kg bw) and at the guidance value (dermal) for a Category 2 classification (2000 mg/kg bw≥C > 1000 mg/kg bw). No classification is required.
The criteria for Transient Organ effects (STOT-SE Category 3) according to the CLP and to the GHS are not met since narcotic effects were not observed in the acute dermal toxicity study.
Specific target organ toxicity: single exposure (Inhalation):
No data was available. However, the registered substance is not a skin or an eye irritant, therefore respiratory tract irritation is not expected.
Aspiration hazard:
The substance is not a hydrocarbon and no effects were observed on lungs in oral studies, therefore the criteria for aspiration toxicity according to the CLP and to the GHS are not met.
