Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 271-240-3 | CAS number: 68526-92-1 A complex combination of hydrocarbons produced by the distillation of products from the hydrogenation of isotridecanal from the hydroformylation of dodecene. It consists predominantly of C10-12 olefins and paraffins and C13 alcohols and aldehydes and boils in the range of approximately 160°C to 253°C (320°F to 487°F).

Description of key information
In a 72 h acute toxicity study freshwater algae (Desmodesmus subspicatus) were exposed to Oxooil LS 13. For both biomass and growth rate, the resulting EL50 value was >100 mg/L loading rate WAF and the No Observed Effect Loading Rate was 100 mg/L loading rate WAF.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
In a 72 h acute toxicity study, freshwater algae (Desmodesmus subspicatus) were exposed to Oxooil LS 13 at a nominal WAF loading rate of 0 and 100 mg/L. For both biomass and growth rate, the resulting EL50 value was >100 mg/L loading rate WAF and the No Observed Effect Loading Rate was 100 mg/L loading rate WAF. However, the total organic carbon (TOC) analysis used to determine test material concentration in WAFs was not reliable. Since Oxooil LS 13 water concentrations during the test period were not analytically confirmed and the batch/lot number is not provided , the present toxicity study is classified as reliable with restrictions according to the OECD guideline Nr. 201.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
