There are no data describing the long-term toxicity of the registered
substance to terrestrial arthropods. Terrestrial test data have been
read-across from the analogue substance, phenyl silsesquioxanes (EC
939-487-8). An earthworm reproduction (OECD 222) and soil microorganism
(OECD 216) test have been conducted with phenyl silsesquioxanes. The
earthworm is the standard organism for soil macroorganisms and there is
no indication that arthropods would be any more susceptible, therefore
the data read-across from the earthworm reproduction test and soil
microorganism tests with phenyl silsesquioxanes are considered to be
suitable to derive hazard and risk assessment under REACH for
octaphenylcyclotetrasiloxane and the requirement for further tests with
terrestrial arthropods is waived.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
