- Executive summary:
A study was conducted to determine the apparent viscosity of the read across substance, C8 -18 and C18 -unsatd. DEA, in accordance with OECD Guideline 114 and ISO Method 3219 using the standard Brookfield method. The apparent viscosity was determined to be 1357 mPa·s at 20ºC (shear rate 25 s-1) (Amin, 2010).
