Water dispersible fragranced film and use thereof
Fragranced films containing a water soluble a/o water dispersible polyvinyl alcohol polymer are disclosed. Uses of the fragranced films in providing a fragrance benefit and/or in controlling malodours is also disclosed, including when used in conjunction with lavatory appliances, dishwashing machines and in laundry washing machines.
1. A fragranced film comprising, a film formed of a water soluble and/or a water dispersible polyvinyl alcohol polymer, wherein the film comprises a fragrance constituent absorbed or adsorbed onto a free-flowing particulate material based on a polysaccharide polymer which fragrance constituent includes one or more components which individually concurrently satisfy the following parameters:
(a) a c Log P<3.00;
(b) a Vapor Pressure >0.1 mm Hg;
(c) a molecular weight of <180, and
where the said components cumulatively comprise not more than about 10% wt. of the fragrance constituent.
2. The fragranced film of claim 1 , wherein the polysaccharide polymer in a particulate form.
3. The fragranced film of claim 1 , wherein the particulate material is microcrystalline cellulose.
4. The fragranced film of claim 1 , wherein the film comprises one or more additional materials.
5. The fragranced film of claim 4 , which comprises a thickener constituent.
6. The fragranced film of claim 4 , which comprises an organic solvent constituent.
7. An article comprising the fragranced film of claim 1 .
8. The article of claim 7 , wherein the article is a pouch, sachet, or other article which further comprises one or more cleaning compositions and/or textile treatment compositions.
9. The article of claim 7 , wherein the article includes as part of its construction, or alternately contains the fragranced film.
10. A method of ameliorating malodors, the method comprising the step of:
providing a fragranced film according to claim 1 to the locus of the malodors which locus also contains water in a sufficient amount to dissolve the water soluble and/or the water dispersible polyvinyl alcohol polymer of the fragranced film.
11. The fragranced film of claim 3 , wherein the microcrystalline cellulose has an average particle size of between 0.01-1000 microns.
12. The fragranced film of claim 1 , wherein the particulate material has a sufficiently small average particle size such that the fragrance constituent is translucent or essentially transparent within the fragranced film.
