In addition to suspensions, pharmaceutical products may be emulsions or foams. In any case the rheological properties have to be tailored to suit the nature of the application [215], Therapeutic ointments are usually not very viscous and encounter only moderate shear rates upon application, about 125 s-1 when gently smeared on with fingers, and about 210 s-1 when smeared on with a spatula [215], An opthalmic ointment is usually very soft, with a viscosity of about 20-30 mPas, whereas a medicated ointment needs to be soft enough to apply easily but stiff enough to remain on the area to which it was applied, with a viscosity of about 30-40 mPas [215], A protective ointment like zinc oxide paste needs to be hard and stiff enough to stay in place where applied, even when moist.
