Abstract:
The present invention is directed to a composition of matter which provides a slow release fragrance for animal skin products such as shampoos, conditioners, insect (e. g. , flea, tick) repellants or insecticides.
The present invention is especially directed to the use of a combination of one or more perfumes and a polymer that, when added to hair coat treatment products for animals, extend the aromatic life of the fragrance.
Preferably, the slow release fragrance composition comprises a fragrance base, such as any of the commercially available perfumes or perfume concentrates, and a water-soluble polymer. Preferably, the polymer is a vinyl copolymer. The most preferred polymer is the copolymer obtained by reaction of the monomers N-vinylpyrrolidone and dimethylamino ethyl methacrylate.
