Abstract

An optically clear, solid water-soluble formulation of odorants and flavorings comprising at least one synthetically prepared odorant and flavoring, in which the odorants and flavorings are embedded homogeneously in a polymer matrix based on polyvinyllactams.

First claim

The invention claimed is:

1. An optically transparent, solid water-soluble formulation of odorants and flavorings consisting of (a) at least one synthetically prepared odorant and flavoring and (b) a polymer matrix based on a graft copolymer of (i) 50 to 60 wt % N-vinyllactam, (ii) 25 to 35 wt % vinyl acetate, and (iii) 10 to 20 wt % of a polyether, with the proviso that the sum of components i), ii), and iii) is equal to 100 wt %, in which the at least one odorant and flavoring is embedded homogeneously in the polymer matrix,
wherein the at least one odorant and flavoring is present in a total amount of 7 to 22 wt %,
and wherein the at least one odorant and flavoring is embedded homogeneously in the polymer matrix in a form of a solid solution.

2. The water-soluble formulation according to claim 1 , comprising a polymer matrix based on a graft copolymer of 13 wt % polyethylene glycol MW 6000, 57 wt % N-vinylcaprolactam, and 30 wt % vinyl acetate, having an average molecular weight of 44 000 daltons.

3. The water-soluble formulation according to claim 1 comprising, as odorants and flavorings, a substance selected from the group consisting of geraniol, linalool, linalyl acetate, pyranol, geranyl acetate, anisaldehyde, citral, citronellal, lysmeral, citronellol, rose oxide, tetrahydrolinalool, hydroxycitronellal, betaionone, menthol, essential oils, cinnamaldehyde, anethole, vanillin, eugenol, cinnamon oil, carvone, piperonal, and complex perfume or flavoring compositions.

4. The water-soluble formulation according to claim 1 comprising, as odorants and flavorings, a substance selected from the group consisting of geraniol, linalool, linalyl acetate, pyranol, geranyl acetate, anisaldehyde, citral, citronellal, lysmeral, citronellol, rose oxide, tetrahydrolinalool, hydroxycitronellal, betaionone, menthol, cinnamaldehyde, anethole, vanillin, eugenol, carvone, and piperonal.

5. The water-soluble formulation according to claim 1 obtained by melt extrusion.

6. The water-soluble formulation according to claim 1 for use as an additive for detergent and dishwashing compositions, as a cosmetic additive, in a pharmaceutical or a food supplement, in a food, or for releasing an odorant in buildings and vehicles.

7. The water-soluble formation according to claim 1 wherein the N-vinyllactam is N-vinylcaprolactam.

8. The water-soluble formation according to claim 1 wherein the polyether is polyethylene glycol.
