EC number: 293-262-2 | CAS number: 91053-00-8 A complex combination of hydrocarbons obtained from distillation of the butadiene-free C4 fraction of a naphtha steam-cracking process. It consists predominantly of olefinic hydrocarbons having carbon numbers of C8, C12, C16 and C20 and boiling in the range of approximately 95°C to 120°C (203°F to 248°F).

Description of key information
The vapour pressure of members of this category (C8 - C16) have been measured in the range 0.0094 - 0.11 Bar (9.4 - 110 hPa) at temperatures in the range 20 - 37.8°C.
Guideline proprietary studies are available. The vapour pressure of 68606-29-1 at 20°C was measured at 3000 Pa [0.03 bar] (Chilworth Global, 2010). The vapour pressure of 91052-99-2 at 37.8°C was measured at 0.11 bar (INEOS 2009). The vapour pressure of 7756-94-7 at 37.8°C was measured at 0.02 bar (INEOS 2009). The vapour pressure of 91053-00-8 at 37.8°C was measured at 0.01 bar (INEOS 2009). The vapour pressure of 97280-83-6 at 20°C was measured at 9.4 hPa [0.0094 bar] (Evonik Oxeno 2009). These data will be read across to other members of the category.
The mean of the vapour pressure values for the category is 19.7 hPa at 20°C and this has been used to complete the 'key value for chemical safety assessment'.
