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.
