Abstract
The present invention is directed to methods, compositions and articles comprising olfactory-active compositions. An article of the present invention comprises a structural component and an olfactory-active composition. The article may control the release, release rate or absorption of the olfactory-active composition. The article may be of various shapes and sizes. A method of use of an article comprises providing fragrance to an environment.
Claims24
A scented article, comprising,
- at least one olfactory-active composition,
- a rod comprising an absorbent matrix material formed of multiple types of paper or pulp composition, the multiple types of paper or pulp composition comprising;
- a first type of paper or pulp composition disposed at an interior of the rod, the first type of paper or pulp composition having a first porosity, and
- a second type of paper or pulp composition disposed at an outer surface of the rod, the second type of paper or pulp composition having a second porosity different from the first porosity, and
- a coating composition disposed on an exterior surface of the outer portion of the rod and covering at least a portion of the rod, wherein the coating composition comprises a wax, soy wax, paraffin, bees wax, polyethylene wax, microcrystalline wax, waxes that soften or melt at a temperature greater than about 150 F, acrylates, polylactide, polyglycolide or polycaprolactone, or a polyester copolymer selected from poly(lactide/glycolide) acid (PLGA) or poly(lactid-co-epsilon-caprolact-one) (PLCL), alkyl- or alkoxyalkyl-2-cyanoacrylates, n-butyl-2-cyanoacrylate, 2-methoxybutyl-2-cyanoacrylate, crosslinked cyanoacrylate, polylactic acid, polyglycolic acid, lactic-glycolic acid copolymers, polycaprolactone, lactic acid-caprolactone copolymers, poly-3-hydroxybutyric acid, polyorthoesters, polyalkyl acrylates, copolymers of alkylacrylate and vinyl acetate, polyalkyl methacrylates, copolymers of alkyl methacrylates and butadiene;
- dioctyl phthalate, dimethyl sebacate, trethyl phosphate, tri(2-ethylhexy)phosphate, tri(p-cresyl)phosphate, glyceryl triacetate, glyceryl tributyrate, diethyl sebacate, dioctyl adipate, isopropyl myristate, butyl stearate, lauric acid, dibutyl phthalate, trioctyl trimellitate, dioctyl glutarate, glaze, starch, or a starch derivative;
- wherein the at least one olfactory-active composition is releasably retained in the absorbent matrix material.
4 more elements
An article comprising:
- an absorbent matrix material wound about a central axis to form a multilayered paper rod, the absorbent matrix material having a first number of perforations per unit area toward the center of the rod and a second number of perforations per unit area toward an outer surface of the rod, the first number different from the second number;
- an olfactory-active composition releasably retained in the absorbent matrix material;
- and
- a coating composition covering at least a portion of the multilayered paper rod, the coating composition comprising one or more of a wax, a polymer, a starch, or a starch derivative.
1 more element
An article comprising:
- an absorbent matrix material that is at least partially coated with a coating composition, wherein the coated absorbent matrix material is wound about a central axis to form a multilayered paper rod, and wherein the coating composition comprises one or more of a wax, a polymer, a starch, or a starch derivative, and wherein the absorbent matrix material has a first porosity toward the center of the rod and a second porosity different from the first porosity toward an outer surface of the rod;
- and
- an olfactory-active composition releasably retained in the absorbent matrix material.
