Vapour pressure

Link to relevant study record(s)

Reference

Endpoint:

vapour pressure

Type of information:

(Q)SAR

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification

Justification for type of information:

The substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint is characterised using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Composition in PETRORISK report attached in IUCLID section 13).

Qualifier:

no guideline required

Principles of method if other than guideline:

Model(s) used: PETRORISK v7.04 that incorporates the updated TLM that resulted from the 2014 – 2016 Concawe projects performed in response to an ECHA compliance check

GLP compliance:

no

Remarks:

(Q)SAR

Key result

Vapour pressure:

6.5 kPa

Remarks on result:

other: temperature is not calculated

Conclusions:

Vapour pressure has been calculated using Petrorisk. The vapour pressure of this substance is 6.5 kPa.

Executive summary:

The substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint is characterised using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Composition in PETRORISK report attached in IUCLID section 13).

Vapour pressure has been calculated using Petrorisk. The vapour pressure of this substance is estimated to be 6.5 kPa.

Description of key information

Hydrocarbons, C6 -C10 (even numbered), n-alkanes, isoalkanes, >5% n-hexane are hydrocarbon UVCBs. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint is fulfilled using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Composition in PETRORISK report attached in IUCLID section 13).

Vapour pressure has been calculated using Petrorisk. The vapour pressure of Hydrocarbons, C6-C10 (even numbered), n-alkanes, isoalkanes, >5% n-hexane is estimated to be 6.5 kPa.
