Abstract: Precursor or pro-fragrance compounds used as a precursor to deliver at least one fragrant compound that is capable of imparting an odor, in particular one which imparts an odor to a material, more particularly to a fabric or textile. The pro-fragrant compounds of the invention include fragrant alcohols (R1OH) released from a compound of Formula I or in which Formula I is derived from (R1OH) and encompass any fragrant alcohol having more than three carbon atoms. Also, methods of generating the fragrant compounds and to improve, enhance or modify odoriferous properties of a perfuming composition or a perfumed article are also disclosed, as are the resultant perfuming compositions and articles.

Abstract: Provided herein is a compound having the formula I wherein R1 and R2 are independently selected from a branched or straight C1-6 alkyl and a C1-6 alkenyl, n is 1, 2, 3, 4, 5, or 6 and x is independently 0, 1, or 2; provided that when n is 1, x is 2. Also provided herein is a method of releasing acetaldehyde into an aqueous solution including delivering a compound of formula I to the aqueous solution, Also provided is a flavor or aroma-modifying composition including i) a flavor or aroma-conferring or modifying ingredient, at least one compound according to formula (I); ii) at least one ingredient selected from the group consisting of a flavor carrier and a flavor base; and iii) optionally at least one flavor adjuvant.

Abstract: Provided herein are flavor particles containing encapsulated precursors of acetylaldehyde. Also provided herein are methods of making and using the particles.

Abstract: A rosin/hydrocarbon hybrid resin is disclosed to be prepared by reacting rosin with a phenolic compound and an aldehyde to form a phenol-modified rosin intermediate which is reacted with dicyclopentadiene at elevated pressure and temperature to form the rosin/hydrocarbon resin. The resin is particularly useful as a lithographic printing ink resin.

Abstract: Phosphinic acid (also called hypophosphorous acid), when used in very small quantities, is disclosed to act as a catalyst to accelerate the reaction of rosin with an unsaturated dibasic acid to form a modified rosin for subsequent esterification with a polyhydric alcohol. According to the process of the invention, a rosin is reacted with an unsaturated dibasic acid such as maleic anhydride or fumaric acid in the presence of phosphinic acid at a temperature of from about 180.degree. C. to about 220.degree. C. When the modified rosin is subsequently esterified, the rosin ester exhibits improved color, softening point, and viscosity in a specified solution.
