Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Based on read across, the static viscosity of Santicizer 278 is 22 mm2.s-1

Key value for chemical safety assessment

22 mm²/s (static)
at the temperature of:
20 °C

Additional information

There is no reliable viscosity data for S278 – a value of 22 mm2.s-1will be read-across from DEHP - a structure which is similar in structure and expected properties to Santicizer 278.

The Merck Index gives a value of 22 mm2.s-1for DEHP’s static viscosity at 20°C. The Merck Index is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

This is supported by a dynamic viscosity measurement of 860 mPas at 25°C from company data.
