Endpoint summary
Administrative data
Description of key information
The acute oral toxicity of Disodium (Z)-1-(octadec-9-enyl) 2-sulphonatosuccinate (CAS 94213 -67 -9) was derived from a key study with read across substance CAS 90268-36-3 containing ≥90% act. ingr., showing LD50 values of <1400 mg/kg and >580 mg/kg for male rats and <1400 mg/kg and >580 mg/kg for female rats.

Additional information
No acute toxicity data were available for the target substance (Disodium (Z)-1 -(octadec-9 -enyl) 2-sulphonatosuccinate: CAS 94213 -67 -9), but read across data were available from source substance CAS 90268-36-3:
- The acute oral toxicity of read across substance CAS 90268-36-3 containing ≥90% act. ingr. was tested in a key study by oral gavage in young Wistar rats at dose levels of 580, 1400 and 2000 mg/kg bw. The test compound was administered by single gavage in aqua dest. as solvent and an application volume of 20 mL/kg bw to fasted animals. Two (low and mid dose) or five rats (high dose) were used per sex and dose. Clinical observations and gross macroscopic observations were observed at all dose levels . The LD50was <1400 mg/kg and >580 mg/kg for male rats and <1400 mg/kg and >580 mg/kg for female rats (Potokar, 1987).
- The acute oral toxicity of read across substance CAS 90268-36-3 containing >= 90% act. ingr. was tested in a supporting study by oral gavage in male Wistar rats. The test item was administered by single gavage in aqua dest. as solvent and an application volume of 20 mL/kg bw to fasted animals at doses of 1.58, 1.99, 2.51 and 3.16 g/kg bw. Ten male rats were used per sex and dose. All animals in all dose groups displayed diarrhea. The LD50was 2.4 g/kg bw (Gloxhuber, 1969).
- Acute oral toxicity of read across substance CAS No. 90268-36-3 containing >= 90% act. ingr. was tested in a supporting study by oral gavage in male and female Wistar rats. The male LD50 was > 2000 mg/kg bw; the female male LD50 was ca. 1400 mg/kg bw (Potockar, 1986).
Justification for classification or non-classification
Based on the available data, the oral LD50 of Disodium (Z)-1-(octadec-9-enyl) 2-sulphonatosuccinate in Wistar rats was established to be between 300-2000 mg/ kg body weight, therefore the substance is classified category 4 for oral toxicity according to CLP Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
