PBT assessment: overall result

Type of composition:
legal entity composition of the substance
State / form:
Related composition:
1,3,5-triisopropylbenzene - boundary composition
Reference substance:
PBT status:
the substance is not PBT / vPvB

Not P: The substance 1,3,5-triisopropylbenzene is readily biodegradable according to OECD criteria.

Not T: not toxic to freshwater fish, not a CMR substance nor classified as a STOT RE according to CLP criteria.


No BCF information is available and the Log Kow is 6.68. The substance, 1,3,5-triisopropylbenzene, is anticipated to undergo Phase I and Phase II enzymatic metabolism and ultimately be metabolized to glucuronide and/or sulphate conjugates following oral dosing which are normally readily excreted. As the substance is neither P nor T, further generation of information on bioaccumulation is not necessary. Additionally, relevant exposure can be excluded as demonstrated in the relevant exposure assessment.
