PBT assessment: overall result

Reference
Name:
(C16)DEQ
Type of composition:
boundary composition of the substance
State / form:
solid: bulk
Reference substance:
Composition 1
PBT status:
the substance is not PBT / vPvB
Justification:

Biodegradation data of MDEA Esterquat C16 is not available, but the structurally similar source substance MDEA-Esterquat C16-18 and C18 unsatd. was readily biodegradable in an OECD 301 B test. The structural and physicochemical similarities between the source and the target substances justify the read-across hypothesis.

The log KOW is calculated to be 3.0. The calculation is based on the measured water solubility and n-octanol solubility of the test item because the test item is a surface active substance and the shake flask method is not appropriate.

No conclusion can be reached based on available information on T properties of the substance.
