Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The toxicity of the test material was determined in Daphnia magna. Under the conditions of the test, no toxic effects were noted and the 48-Hour EL50 based on nominal loading rates was greater than 100 mg/l loading rate WAF. The No Observed Effect Loading rate was 100 mg/l loading rate WAF.
Key value for chemical safety assessment

Additional information
The potential for hydrocarbon waxes to cause acute toxic effects to aquatic invertebrates was determined in a GLP compliant study (Goodband, 2012b) performed according to the standardised guidelines OECD 202 and Method C.2 of the Commission Regulation (EC) No. 440/2008. The study was reported in sufficient detail to provide an accurate assessment of the results and study quality.
The study was performed to a good standard and was assigned a reliability score of 1 using the principles for assessing data quality as set out in Klimisch (1997).
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.
