Abstract
Described herein is a perfume composition including at least one sulfur-containing pro-fragrance compound and at least one aldehydic perfumery raw material, where the at least one aldehydic perfumery raw material is present in an amount effective to reduce the formation of hydrogen sulfide from the sulfur-containing pro-fragrance. Also described herein are consumer products including the perfume composition as well as the use of at least one aldehydic perfumery raw material for reducing the formation of hydrogen sulfide from a sulfur-containing pro-fragrance.
Claims21
A perfume composition comprising at least one sulfur-containing pro-fragrance compound and at least one aldehydic perfumery raw material, wherein the at least one aldehydic perfumery raw material is present in an amount effective to reduce the formation of hydrogen sulfide from the sulfur-containing pro-fragrance compound, and
- wherein the at least one aldehydic perfumery raw material has a chemical structure selected from the group consisting of R—CH2—CHO and R′—CH(R′)—CHO;
- wherein R represents a hydrogen atom, or a C1 to C18 hydrocarbon group, optionally comprising one to three oxygen atoms and/or one to two nitrogen atoms and/or one sulfur atom:
- wherein each R′, independently from each other, represents a C1 to C18 hydrocarbon group, optionally comprising one to three oxygen atoms and/or one to two nitrogen atoms and/or one sulfur atom;
- or both R′, when taken together, form a C5-16 cycloalkyl, C5-16 cycloalkenyl, C4-14 heterocycloalkyl or C4-14 heterocycloalkenyl group, each optionally substituted with one or more of a C1-15 alkyl, C2-15 alkenyl, C1-15 alkoxy, C3-15 cycloalkyl, C5-15 cycloalkenyl, C6-10 aryl and/or C6-10 aryloxy group, each optionally substituted with one or more of a C1-8 alkyl, C1-8 alkoxy, carboxylic acid and/or C1-4 carboxylic ester group, wherein the heteroatom represents one or more of an oxygen atom.
A method for reducing the formation of hydrogen sulfide from a sulfur-containing pro-fragrance compound, the method comprising adding at least one aldehydic perfumery raw material to the sulfur-containing pro-fragrance compound,
- wherein the at least one aldehydic perfumery raw material has a chemical structure selected from the group consisting of R—CH2—CHO and R′—CH(R′)—CHO;
- wherein R represents a hydrogen atom, or a C1 to C18 hydrocarbon group, optionally comprising one to three oxygen atoms and/or one to two nitrogen atoms and/or one sulfur atom;
- and
- wherein each R′, independently from each other, represents a C1 to C18 hydrocarbon group, optionally comprising one to three oxygen atoms and/or one to two nitrogen atoms and/or one sulfur atom;
- or both R′, when taken together, form a C5-16 cycloalkyl, C5-16 cycloalkenyl, C4-14 heterocycloalkyl or C4-14 heterocycloalkenyl group, each optionally substituted with one or more of a C1-15 alkyl, C2-15 alkenyl, C1-15 alkoxy, C3-15 cycloalkyl, C5-15 cycloalkenyl, C6-10 aryl and/or C6-10 aryloxy group, each optionally substituted with one or more of a C1-8 alkyl, C1-8 alkoxy, carboxylic acid and/or C1-4 carboxylic ester group, wherein the heteroatom represents one or more of an oxygen atom.
