Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
LC50 96h Danio Rerio > 1000 mg/l loading rate, corresponding to > 83 mg/l measured concentration
LC50 96h Danio Rerio > 100 mg/l has been chosen as representative value since no effect has been observed up to the measured concentration of 83 mg/l.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish

Additional information
The acute lethal toxicity of the multi-constituent substance " Reaction mass of dodecane-1-thiol and tridodecyl trithiophosphite" to the Zebrafish Danio rerio was investigated according to test guideline OECD TG 203, under static exposure conditions over a period of 96 h. The result was LC50 96h Zebrafish Danio rerio > 1000 mg/l loading rate, corresponding to > 83 mg/l measured concentration. According to ECHA guidance R7b for slightly soluble substance for which no effect at concentration below 100 mg/l was observed, the PNEC should be calculated on limit value of solubility in the medium. For this substance the limit of solubility in the medium is expected to be similar to the solubility of the substance in water (i.e. 96.3 mg/l) approximated to 100 mg/l. LC50 96h Danio Rerio > 100 mg/l has been chosen as representative value since no effect has been observed up to the measured concentration of 83 mg/l.
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.
