PBT assessment: overall result

Reference
Name:
Reactive Navy FC63805
Type of composition:
legal entity composition of the substance
State / form:
solid: particulate/powder
Reference substance:
Composition 1
Reference substance:
Composition 1
PBT status:
the substance is not PBT / vPvB
Justification:

Persistence: The substance is relatively unstable to hydrolysis. At pH 7 and 25 °C the calculated half-life is 59 hours, the substance is stable at pH 4 and very instable at pH 9 (DT50 < 24 h). Since the breakdown products are unknown, their stability/persistence cannot be assessed. Biodegradation was not observed in a ready biodegradation modified MITI test or a ready biodegradation modified OECD screening test. The substance is therefore considered P but not vP.

Bioaccumulation: The measured log Kow is -6.6 at 20°C indicating no potential for bioaccumulation.

Toxicity: Long-term toxicity data exists for freshwater green algae and invertebrates. The ErC10 and NOEC values are >> 0.01 mg/L. The substance is not acutely toxic to fish (96-h LC50 > 100 mg/L). The substance is not classified for CMR properties or as STOT RE 1/2.
