The present invention provides a mammalian teat dip composition capable of
being used during a mammal's dry period comprising a solution of a
film-forming polymer blend comprising a first polymer component which is
an organic, solvent-soluble, preformed, thermoplastic polyurethane having
no reactive isocyanate groups and a second polymer component which is a
hydrophilic poly(N-vinyl lactam), said blend capable of withstanding
exposure to water without significant loss of said hydrophilic
poly(N-vinyl lactam) in an amount sufficient to form a water-resistant
film upon topical application to mammalian skin; and wherein said blend
comprises from about 10 to about 80 weight percent of said first polymer
in combination with said solvent and from about 1 to about 20 weight
percent of said second polymer; and at least one antimicrobial agent in an
amount sufficient to treat and protect mammalian skin from infection;
wherein said composition is capable of being removed by peeling.
