Abstract
Abstract Safranic acid esters having the general formula ##STR1## wherein the dotted lines represent two conjugated double bonds in the positions 2 endocyclic and 4 (α-isomer), 1 and 3 (β-isomer) or 2 exocyclic and 3 (γ-isomer), R 1 represents an alkyl group containing at least 2 carbon atoms, or, in the γisomers an alkylidene group with 2 or 3 carbon atoms and R 2 represents an alkyl or alkenyl group with 3 or 4 carbon atoms in the form of a perfumed product or flavoring composition. A process for the preparation of a perfumed product or flavoring composition wherein the safranic acid esters are incorporated with other suitable constituents.

Total Claims: 8
Claim 1
Independent Claim
113 words
A process for the preparation of a perfume composition which comprises the incorporation of one or more esters having the formula ##STR7## wherein the dotted lines represent two conjugated double bonds in the position 2 endocyclic and 4(α-isomer), 1 and 3 (β-isomer) or 2-exocyclic and 3(γ-isomer) and wherein R 1 represents an alkyl group or, in the γ-isomers and alkylidene group, with 1-3 carbon atoms and R 2 represents an alkyl or alkenyl group with 1-4 carbon atoms as a perfuming agent in a quantity of at least 0.5 ppm based on the final perfume composition to impart a herbal, spicy or fruity note with other constituents suitable for inclusion in such products.
Claim 2
Dependent Claim
113 words
A process for the preparation of a perfume composition which comprises the incorporation of one or more esters having the formula ##STR7## wherein the dotted lines represent two conjugated double bonds in the position 2 endocyclic and 4(α-isomer), 1 and 3 (β-isomer) or 2-exocyclic and 3(γ-isomer) and wherein R 1 represents an alkyl group or, in the γ-isomers and alkylidene group, with 1-3 carbon atoms and R 2 represents an alkyl or alkenyl group with 1-4 carbon atoms as a perfuming agent in a quantity of at least 0.5 ppm based on the final perfume composition to impart a herbal, spicy or fruity note with other constituents suitable for inclusion in such products.
Claim 3
Dependent Claim
104 words
A perfume composition which comprises one or more esters having the formula ##STR8## wherein the dotted lines represent two conjugated double bonds in the position 2 endocyclic and 4(α-isomer), 1 and 3 (β-isomer) or 2-exocylic and 3(γ-isomer) and wherein R 1 represents an alkyl group or, in the γ-isomers an alkylidene group, with 1-3 carbon atoms and R 2 represents an alkyl or alkenyl group with 1-4 carbon atoms as a perfuming agent in a quantity of at least 0.5 ppm based on the final perfume composition to impart a herbal, spicy or fruity note and other constituents suitable for inclusion in such products.
Claim 4
Dependent Claim
104 words
A perfume composition which comprises one or more esters having the formula ##STR8## wherein the dotted lines represent two conjugated double bonds in the position 2 endocyclic and 4(α-isomer), 1 and 3 (β-isomer) or 2-exocylic and 3(γ-isomer) and wherein R 1 represents an alkyl group or, in the γ-isomers an alkylidene group, with 1-3 carbon atoms and R 2 represents an alkyl or alkenyl group with 1-4 carbon atoms as a perfuming agent in a quantity of at least 0.5 ppm based on the final perfume composition to impart a herbal, spicy or fruity note and other constituents suitable for inclusion in such products.
