One common property of skin creams/moisturizers is the amount
of water emulsified into the cream. For best results in bike use
to reduce skin irritation on the crotch and inner thighs look for
a cream that does not have water listed in the ingredients, or
if it does the water is at least 5-6 down from the start. The
greater the water content, the shorter the life of the lube in
actual use. Vaseline is the basic ingredient for appropriate
long lived skin lubes: Bag balm or udder cream are basically
vaseline with an odorant such as menthol or wintergreen.
Try noxzema type creams and after an hour you will be hard
put to find any residual in your PP. Smear a tspn of vaseline
and it will still be there at the end of your double century.
Women like creams that 'vanish', the way they vanish is the
water evaporates and the residual is smeared out so thin it is
not too greasy on the hands. Bikers needing such do NOT
want vanishing creams. Lanolin is nearly equally long lived if you
don't mind smelling like a sheep. Coca butter ditto except for
the smell.
