Justification:

PERSISTENCY :

SINODOR CQ is NOT persistent. The test item was observed to be READILY Biodegradable in an OECD 301F ready Biodegradation study undergoing 80% biodegradation after 28 days in the test conditions. The 10-day window criterion was also fulfilled (14% biodegradation on day 4 and 65% on day 14).

Based on Persistency alone, it can, therefore, be stipulated that SINODOR CQ is neither P B T nor vP vB.

BIOACCUMULATION :

The LogPow of the main peak of SINODOR CQ is 6.0. In the absence of a higher-tier assessment (e.g. OECD 305), the screening criteria would identify SINODOR CQ as a potential B / vB.

TOXICITY :

Three trophic levels of freshwater species have been tested for short-term acute toxicity. None of the EC/LC50 values determined were < or = 0.01 mg/L.

Long-term toxicity end-points exist for three trophic levels of freshwater species :

- Algae (P. subcapitata) : ErC10 = 0.028 mg/L

- Freshwater Invertebrate (C. dubia) : NOEC = 0.1 mg/L

- Freshwater Fish. (P. promelas) : NOEC > = 0.79 mg/L

All EC10 / NOEC values are > 0.01 mg/L.

Likely routes of exposure:

Theoretically, SINODOR CQ may find its way in to the environment via wide-dispersive down-the-drain use.
