Endpoint summary
Administrative data
Description of key information
An acute oral LD50 value >2000 mg/kg bw in rats was determined in a study conducted in accordance with OECD 425 (up & down method) and in compliance with GLP (inveresk, 2002). There were no mortalities or other treatment-related findings in the study.
An acute dermal LD50 >2000 mg/kg bw in rats was determined in a study carried out in accordance with OECD 402 and in compliance with GLP (ARC, 2005a). There were no mortalities, treatment-related systemic effects or local effects during the study.

Additional information
Acute oral toxicity:
The key acute oral toxicity study is the only study available for this endpoint. The test was carried out in accordance with OECD Test Guideline 425 and in compliance with GLP, and was therefore assigned Reliability 1. The observed LD50 was greater than 2000 mg/kg bw.
Acute dermal toxicity:
The key acute dermal toxicity study is the only study available for this endpoint. The test was carried out in accordance with OECD Test Guideline 402 (limit test) and in compliance with GLP, and was therefore assigned Reliability 1. The observed LD50 was greater than 2000 mg/kg bw.
Acute inhalation toxicity:
No data are available for acute inhalation toxicity.
Justification for classification or non-classification
Based on reliable studies via the oral and dermal routes, Tall Oil Pitch is not classified for acute toxicity according to the criteria of EU Directive 67/548/EEC or Regulation 1272/2008.
No data are available for the inhalation route.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
