ABSTRACT:
Improved film-forming skin protectant compositions are provided which are capable of forming a long-lasting elastic barrier film when applied to skin; the compositions have particular utility as barrier teat dips, for protecting cows against mastitis, especially during their susceptible non-lactating periods. The compositions include a film-forming component (preferably a mixture of polyether polyurethane and benzoin gum) dispersed in a compatible carrier and further having a minor amount of nitrocellulose incorporated therein in order to increase the time of adherence of the composition to skin, as compared with an otherwise identical composition without nitrocellulose. The compositions may also include a germicide (e.g., chlorhexidine diacetate), and a coloring dye. The most preferred compositions include polyether polyurethane, benzoin gum, a solvent system made up of tetrahydrafuran and a lower alcohol, and chlorhexidine diacetate.
