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.
Claims8
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.
