Administrative data

Endpoint:
basic toxicokinetics
Type of information:
other: expert statement
Adequacy of study:
key study
Study period:
2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Theoretical assessment taking all currrently available relevant information into account, based on the REACH Guidance: Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.7c Endpoint specific guidance. Since this is a theoretical assessment, the Klimisch value cannot be 1.

For risk assessment purposes, absorption factors for this substance are derived to be 50% (oral), 100% (inhalation) and 100% (dermal) for risk assessment purposes.

Applicant's summary and conclusion

Conclusions:
A toxicokinetic assessment was performed based on the available data of the substance. Based on the physical/chemical properties of the substance, absorption factors for this substance are derived to be 50% (oral), 100% (inhalation) and 10% (dermal) for risk assessment purposes. The bioaccumulation potential is expected to be low.
