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

Viscosity:
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.
