Description of key information

LC50 (28-day): 813 mg/kg dry weight, mortality Folsomia candida, measured, reliability 2, read-across from CAS: 541-02-6
IC50 (28-day): 767 mg/kg dry weight reproduction, Folsomia candida, measured, reliability 2, read-across from CAS: 541-02-6
NOEC (28-day): 377 mg/kg dry weight mortality and reproduction, Folsomia candida, measured, reliability 2, read-across from CAS: 541-02-6

Key value for chemical safety assessment

Additional information

There are no data describing the long-term toxicity of the registered substance to terrestrial arthropods. However, data are available for the siloxane decamethylcyclopentasiloxane (D5, CAS: 541-02-6). A 28-day LC50 value of 813 mg/kg dry weight and a 28 day IC50 value of 767 mg/kg dry weight have been determined for the effects of the test substance on mortality and reproduction of Folsomia candida. A NOEC of 377 mg/kg dry weight has been determined by the reviewer on the basis of a visual examination of the data for both mortality and reproduction. The read-across is considered to be reliability 2.
