Abstract
Abstract A method is presented for using scented oils to provide odor to a container of a product having a constituent incompatible with the scented oils. An aqueous emulsion which comprises from about 4% to about 70% of a water-emulsifiable or water-soluble polymer, from about 5% to about 80% of scented oils, and from about 6% to about 80% of water is prepared. The aqueous emulsion is dried whereby the scented oils are entrapped within the matrix of the polymer. The polymer matrix is included in the container with the product whereby the scented oils are protected by the polymer matrix from degradation by the incompatible constituent and diffuse from the polymer matrix over a period of time.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
116 words
"A method for using scented oils to provide odor to a container of a product having a constituent incompatible with said scented oils, said method comprising: (a) preparing an aqueous emulsion comprising: (1) from 4% to 70% of a water-emulsifiable polymer and/or a water-soluble polymer, (2) from 5% to 80% of scented oils, and (3) from 6% to 80% of water; (b) drying said aqueous emulsion, whereby said scented oils are entrapped within a matrix of said polymer; and (c) including said polymer matrix in said container with said product, whereby said scented oils are protected by said polymer matrix from degradation by said constituent and diffuse from said polymer matrix over a period of time.
Claim 2
Dependent Claim
116 words
"A method for using scented oils to provide odor to a container of a product having a constituent incompatible with said scented oils, said method comprising: (a) preparing an aqueous emulsion comprising: (1) from 4% to 70% of a water-emulsifiable polymer and/or a water-soluble polymer, (2) from 5% to 80% of scented oils, and (3) from 6% to 80% of water; (b) drying said aqueous emulsion, whereby said scented oils are entrapped within a matrix of said polymer; and (c) including said polymer matrix in said container with said product, whereby said scented oils are protected by said polymer matrix from degradation by said constituent and diffuse from said polymer matrix over a period of time.
