A teat dip composition of hydrophilic polymer blends used for dry cow therapy

摘要

Disclosed herein is a mammalian teat dip composition capable of being used during a mammal's dry period comprising: (i) 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 a dermatologically-acceptable solvent, and from about 1 to about 15 weight percent of said second polymer; (ii) at least one antimicrobial agent in an amount sufficient to treat and protect mammalian skin from infection; and (iii) a buffering agent in an amount to provide said composition with a pH of about 4 to about 8; wherein said composition is capable of being removed by peeling, and wherein the mammal is non-human.
