What is claimed is: 1. A composition comprising: a fragrance material; said fragrance material encapsulated by a polymer to provide a polymer encapsulated fragrance; the polymer encapsulated fragrance is further coated by a cationic polyamine polymer, said cationic polyamine polymer being a reaction product of polyamine and an oxirane material, wherein said oxirane material is selected from the group consisting of (chloromethyl) oxirane, (bromoethyl) oxirane and mixtures thereof. 2. The composition of claim 1 wherein the fragrance is a liquid thereby providing a liquid core to the polymer encapsulated fragrance. 3. The fragrance of claim 1 wherein the fragrance material is not water soluble. 4. The composition of claim 1 wherein the fragrance material is from about 10 to about 50 weight percent of the composition. 5. The composition of claim 1 which is incorporated into a product selected from the group consisting of a personal care, fabric care and cleaning products. 6. The composition of claim 5 wherein the personal care product is selected from the group consisting of hair shampoos, hair rinses, bar soaps, and body washes. 7. A method for imparting an olfactory effective amount of fragrance into a wash-off product comprising: providing a fragrance material; encapsulating the fragrance material with a polymer to form a polymer encapsulated fragrance; providing a polyamine polymer to the surface of the polymer encapsulated fragrance to form a cationically coated polymer encapsulated material, said polyamine polymer being a reaction product of polyamine and an oxirane material; and providing the coated polymer encapsulated material to a rinse off product, wherein, said oxirane material is selected from the group consisting of (chloromethyl) oxirane, (bromoethyl) oxirane and mixtures thereof. 8. The method of claim 7 wherein the encapsulating polymer is selected from a vinyl polymer; an acrylate polymer, melamine-formaldehyde; urea formaldehyde and mixtures thereof. 9. The composition of claim 1 wherein the polymer coating comprises a reaction product of polyamines and (chloromethyl) oxirane or (bromomethyl) oxirane and an additional cationic polymers. 10. A wash-off product comprising an olfactory effective amount of the compound of claim 1. 11. The wash-off product of claim 10 wherein the wash-off product is selected from the group consisting of personal care, fabric care and cleaning products.
