EC number: 293-261-7 | CAS number: 91052-99-2 A complex combination of hydrocarbons obtained from distillation of the butadiene-free C4 fraction of a naphtha steam-cracking process. It consists predominantly of branched olefinic hydrocarbons having carbon numbers of C8, C12, C16 and C20 and boiling in the range of approximately 105°C to 120°C (221°F to 248°F).

Description of key information
The densities of substances in this category were measured to be in the range 0.77 (C12) - 0.81 (C16) g/mL at 20°C.
A guideline study (Evonik Oxeno, 2008) is available. The density at 20°C of 97280-83-6 was measured as 0.77 g/mL. Supporting studies from Evonik (2008) for 97280-83-6 and Aqura (2006, 2007) for tetrabutene reported a density of 0.7736 g/cm3 and 0.8097, 0.8118 g/mL respectively.
These values are considered to be representative of the category.

EC# 500-004-7_Intertek 2019_Key: 0.8017 Kg/L at 15ºC
EC# 293-263-8_Intertek 2019_Key: 0.7629 Kg/L at 15ºC.
EC# 306-479-5_Intertek 2019_Key: 0.7718 Kg/L at 15ºC.
EC# 293-262-2_Intertek 2019_Key: 0.798 Kg/L at 15ºC.
The mean of the relative density values for the category is 0.7914 at20 °C and this has been used to complete the 'key value for chemical safety assessment'.
