Endpoint:
boiling point
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Justification for type of information:
Beta-terpineol one of the main impurities of multiconstituent substance TERPINEOL MULTICONSTITUENT. Therefore, data on beta-terpineol can be used for extrapolation to TERPINEOL MULTICONSTITUENT.

Description of key information

The boiling point of terpineol multiconstituent is 210-225°C at standard atmospheric pressure.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
210 °C

Additional information

According to numerous secondary literature sources (hanbooks and review articles), boiling points of terpineol multiconstituent and of terpineol isomers are in the same order of magnitude. Therefore a Weight of Evidence approach is followed for this end point and is based on data related to the substance and to terpineol isomers.
