Endpoint summary
Administrative data
Description of key information
Acute oral toxicity (OECD 423, rat, f): LD50 > 2000 mg/kg bw
Acute inhalation toxicity: No study required as the inhalation route of exposure is considered less relevant than the dermal route.
Acute dermal toxicity: According to the REACH Regulation (EC) No. 1907/2006, Annex VIII, Section 8.5, Column 2, no study is required. Sorbitan tridocosanoate (CAS 9380-59-7) does not meet the criteria for classification for acute toxicity or Specific Target Organ Toxicity after Single Exposure (STOT SE) by the oral route and no systemic effects have been observed in in vivo studies with dermal exposure (e.g. skin sensitisation).
Key value for chemical safety assessment

Additional information
Acute oral toxicity:
Sorbitan tridocosanoate was tested for acute oral toxicity according to OECD guideline 423 (Acute Toxic Class Method) and in compliance with GLP (Riken Vitamin, 2017). The test item was dissolved in 0.5% aqueous methylcellulose and applied to groups of 3 female Sprague-Dawley rats at dose levels of 2000 and 300 mg/kg bw. Following administration, the animals were observed for a time period of 14 days to assess general health, body weight gain and mortality. Thereafter, all animals underwent gross macroscopical examination.
No mortality was observed during the study period and there were no clinical signs of toxicity noted for any animal. All animals gained body weight as expected. At scheduled necropsy, no abnormal findings were observed. Under the conditions of the test, the acute oral lethal dose (LD50) was > 2000 mg/kg bw for female rats.
Justification for classification or non-classification
The available data on acute oral toxicity do not meet the criteria for classification according to Regulation (EC) No. 1272/2008, and are therefore conclusive but not sufficient for classification.
No information on acute toxicity via the inhalation and dermal routes of exposure are available for sorbitan tridocosanoate because the inhalation route is considered less relevant than the dermal route and the substance does not meet the criteria for classification for acute toxicity or Specific Target Organ Toxicity after Single Exposure (STOT SE) by the oral route and no systemic effects have been observed in in vivo studies with dermal exposure (e.g. skin sensitisation).
