Lotion transfer was determined gravimetrically (Sartorius BP221, Mettler, Toledo). The wipes were weighed before and after use. Two correction factors were applied to the gravimetric mea- sure to determine the lotion transfer to the baby’s skin. First, a control wipe was left untouched during the wiping process, but weighed before and after to determine loss due to evaporation. Second, the primary caregivers were asked to wear disposable ex- amination gloves during the wiping procedure. The gloves were weighed before and after to determine lotion transfer to the gloves.
