| abstract |
A composition and method for the topical application of a water dispersible active ingredient to a surface of a warm blooded animal is provided. Specifically, such composition is provided to have the properties of being readily flowable at room temperature upon filling a container therewith, maintaining such flowable condition after storage for a substantial length of time and being readily flowable upon application to the desired animal situs. Uniquely, upon contact with the warm surface of the animal then, and only then, does the composition quickly form into a non-flowable relatively substantive gel. Specifically such composition comprises: (a) a water soluble nonionic block copolymer of ethylene oxide and propylene oxide of the formula HO(C2H4O)a (C3H6O)b (C2H4O)cH; (b) the active ingredient to be topically delivered; and (c) water. o |
