Method: OECD Test Guideline 301B
12.3 Bioaccumulative potential
Dodecamethyl cyclohexasiloxane
Bioaccumulation: Bioconcentration potential is low (BCF less than 100 or log Pow greater
than 7).
Partition coefficient: n-octanol/water(log Pow): 8.87
12.4 Mobility in soil
Dodecamethyl cyclohexasiloxane
Potential for mobility in soil is very high (Koc between 0 and 50).
12.5 Results of PBT and vPvB assessment
Dodecamethyl cyclohexasiloxane
Dodecamethyl cyclohexasiloxane (D6) meets the current REACh Annex XIII criteria for vPvB.
However, D6 does not behave similarly to known PBT/vPvB substances. The weight of
scientific evidence from field studies shows that D6 is not biomagnifying in aquatic and
terrestrial food webs. D6 in air will degrade by reaction with naturally occurring hydroxyl
radicals in the atmosphere. Any D6 in air that does not degrade by reaction with hydroxyl
radicals is not expected to deposit from the air to water, to land, or to living organisms.
12.6 Other adverse effects
Dodecamethyl cyclohexasiloxane
This substance is not on the Montreal Protocol list of substances that deplete the ozone layer.
