An active ingredient in Desitin (TM), a
diaper rash ointment, as well as in the many
generics available. Also found in some (not all that common)
sunscreens: that "white nose" look.
When used in diaper rash ointment, it is combined with oil, lanolin, talc, and artificial fragrances. It helps protect the skin against chafing and provides a layer of protection for damp (groin) areas. It feels grainy, moist and it lubricates, but not nearly as much as something like Vasoline.
When used in sunscreens, it provides UV blocking.
