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.

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 consisting essentially of:
- (1) from about 4% to about 70% of a polymer, said polymer being selected from a group consisting of water-emulsifiable polymers and water-soluble polymers,
- (2) from about 5% to about 80% of scented oils, and
- (3) from about 6% to about 80% of water;
- (b) drying said aqueous emulsion, whereby said scented oils are entrapped within a matrix of said polymer;
- and
- (c) including a coating of said polymer matrix on a surface of said container of 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.
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 adhesive aqueous emulsion consisting essentially of:
- (1) from about 4% to about 70% of a polymer, said polymer consisting of the group selected from water-emulsifiable polymers and water-soluble polymers,
- (2) from about 5% to about 80% of scented oils, and
- (3) from about 6% to about 80% of water;
- (b) spreading said aqueous emulsion on a surface to which said emulsion adheres;
- (c) drying said aqueous emulsion, whereby said scented oils are entrapped within a matrix of said polymer which is adhered to said surface;
- and
- (d) including said surface with said polymer matrix adhered thereto 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.
An aqueous emulsion comprising:
- (a) from about 4% to about 40% of a water-emulsifiable polymer;
- (b) from about 45% to about 80% of scented oils;
- and
- (c) from about 6% to about 45% of water.
