Qualifier:
according to guideline
Guideline:
other: USP 40/NF 35 <911> Method I
GLP compliance:
no

Key result
Temp.:
other: 25.0°C
Parameter:
kinematic viscosity (in mm²/s)
Value:
ca. 921

The kinematic viscosity is calculated by multiplying the efflux time by the viscometer constant. dynamic viscosity (cP) = kinematic viscosity (cSt) × density (g/cm3)

Conclusions:
The kinematic viscosity of Benzene sulfonic acid, di-C10-14-alkyl derivs., sodium salts is 921.0 mm2/s (cST) at 25C.

Description of key information

The kinematic viscosity (at 25˚C) of the registered substance (in the presence of the oil additive) additive was determined to be 921.0 mm2/s (cST) at 25°C according to USP 40/NF 35 911 Method I, and conducted under good manufacturing practices (GMP).
