Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusions:
The vapour pressure of the substance Cyclopentadecanone at 25°C was determined to be <= 0.63 Pa.
The vapour pressure at 20°C was determined to be <=0.40 Pa.
Executive summary:

The vapour pressure of the substance Cyclopentadecanone was determined using the isothermal thermogravimetric effusion method in a GLP study according to EC A.4, OECD 104 and OPPTS 830.7950. The vapour pressure at 25°C was determined to be <= 0.63 Pa. The vapour pressure at 20°C was determined to be <=0.40 Pa. Reported as less than or equal to value because determined using data obtained above the melting point and therefore overestimated.

Description of key information

The vapour pressure of the substance was determined to be <=0.40 Pa at 20°C. The vapour pressure at 25°C was determined to be <= 0.63 Pa.

Determined using the isothermal thermogravimetric effusion method, using weight losses obtained at 70°C - 100°C.

Reported as less than or equal to values because determined using data obtained above the melting point and therefore overestimated.

Key value for chemical safety assessment

Vapour pressure:
0.009 Pa
at the temperature of:
40 °C

Additional information

As key value for the CSA in Chesar, to use for the calculations with the ECETOC TRA Worker tool in Chesar, it is considered appropriate to use for this (solid) substance a value that results in inhalation exposure estimates in the lowest exposure band for liquids (<0.01 Pa). Not only is the experimentally determined vapour pressure overestimated, but this solid substance is dissolved in liquids, containing many other substances.
