Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

cPs equates to cSt on a 1:1 basis, hence kinematic viscosity is considered to be in the range of 51 to 57 cSt at 25 deg C. It is anticipated that a temperature increase of 15 deg C will not be sufficient to lower the viscosity to < 20,5 mm 2 /s or less. Classification as "H304: May be fatal if swallowed and enters airways" is not applicable.

Conclusions:
Brookfield viscometer was used to determine the dynamic viscosity of Heptanal, oligomeric reaction products with aniline.
Under the conditions of the experiment it was concluded that the test substance has a dynamic viscosity of between 51.0 - 57.0 cPs when measured at 25°C.
