Viscous liquid conditioning topical germicides
DCFirst Claim
1. A topical germicide consisting essentially of an aqueous composition including a germicidal agent selected from the group consisting of iodine and chlorhexidene, a thickener, from about 0.5-20% by weight of a skin conditioning agent selected from the group consisting of glycerin and propylene glycol and mixtures thereof, and an amount of polyvinyl pyrrolidone, said composition having a viscosity of from about 50-5000 cP and characterized by the property of leaving a residual film when applied to skin.

Abstract
Improved, highly viscous film-forming protective germicidal formulations are provided which include water, a germicidal agent (preferably complexed iodine) together with an organic thickener, a skin conditioning agent and a minor amount of polyvinyl pyrrolidone. Preferably, the formulations include iodine complexed with a Poloxamer and PVP, in combination with a xanthan gum and glycerin. The formulations have a viscosity of from about 50-5000 cP and form a flexible residual film when applied to skin. The invention is particularly useful in the preparation of bovine teat dips.
