Additional information

The substance has an aspiration hazard in view of its kinetic viscosity of the following constituents:

Peak 1 CAS 22567-43-7, nonspecific isomer determination of CAS 469-61-4 (alpha Cedrene), which is classified as H304;

Peak 2 CAS65450-98-8, nonspecific isomer determination of CAS 546-28-1, (Beta Cedrene), which is classified as H304;

Peak 3, CAS 32435-95-3, nonspecific isomer determination of CAS 470-40-6 (Thujopsene), which is classified as H304.

In addition, the defined the viscosity of this material as 18.2 cP, which given the density of 0.9761 translates to a kinematic viscosity of ca 19 mm2/s at 25o C, this is below the EU CLP cut off > 20.5 mm2/s at 40oC above which classification is not needed. Because viscosity tends to decrease over temperature it is likely that the viscosity remains below 20.5 mm2/s. Therefore the substance receives the aspiration hazard based on the 10% rule of the substance containing hydrocarbons.

Based on these results the substance will receive Aspiration Hazard 1 according to EU CLP (EC No. 1272/2008 and its amendments) and the risk phrase is assigned: H304, May be fatal if swallowed and enters airways.
