Additional information
The influence of dichloromethyl(3,3,3-trifluoropropyl)silane on the growth of the green algal species Pseudokirchneriella subcapitata was investigated in a 72-hour static test according to the OECD Guideline 201 and GLP (Softcheck, 2012). The nominal test concentrations were 0.63, 1.3, 2.5, 5.0 and 10 mg/l in parallel with a control. A 72 hour EC50value of > 10 mg/l and NOEC of 10 mg/ l have been determined.
Although the water solubility of dichloromethyl(3,3,3-trifluoropropyl)silane in laboratory well water is 50 mg/l (Fournier, 2012),10 mg/l is the maximum achievable concentration in algal growth medium (the dilution water used for this study) that will yield a fully soluble test concentration without the formation of insoluble polymer structures. Based on the expected rapid hydrolysis of the test substance into a mixture of monomeric and oligomeric products, the effects are attributed to the mixture and are presented based on nominal loading rates of parent test substance. Therefore no further testing was conducted to defineEC50values as the highest loading rate aligns tested, i. e., 10 mg/l represents the maximum achievable concentration for this test substance under study conditions.
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).
