The present invention relates to the use of a composition containing 1,8-para-menthenethiol and 3-mercaptohexyl acetate, such as a plant extract and in particular an extract of timur (Zanthoxylum armatum), as odor-masking agent. It also relates to a deodorizing product in the form of an aerosol, candle, or electrical or wick fragrance diffuser, containing this composition.

Described herein are compounds that are able to generate oct-2-en-4-one and thus to provide a long-lasting or substantive strawberry odor to an environment. Also described herein is a method of imparting a long-lasting strawberry odor to surfaces, such as hard surfaces, fabric, skin or hair. Also described herein is a method of using said compounds in perfumery. Also described herein are perfuming compositions or perfumed articles including the compounds.

A method of countering malodour in a washing machine at the end of a wash cycle, comprising the addition thereto of a fragrance precursor. The fragrance precursor may be added alone in solution, or as part of a fabric softener/conditioner. The precursor is particularly ethyl (Z)-2-acetyl-4-methyltridec-2-enoate; ethyl N,S-bis(4-oxo-4-(2,6,6-trimethylcyclohex-3-en-1-yl)butan-2-yl)cysteinate; 4-(dodecylthio)-4-methylpentan-2-one; 1-butoxy-3-((1E,4Z)-hepta-1,4-dien-1-yl)benzene; 2-ethoxy-4-((1E,4Z)-hepta-1,4-dien-1-yl)phenol; and mixtures thereof.

The use of precursor in this manner provides a washing machine that is free from malodour for a prolonged period.

An edible composition, an aerosol composition, a flavor composition, a fragrance composition, or an inhalable composition includes an organosulfur compound such as prenyl mercaptan, 2-methylthiophene, 3-methylthiophene, dimethyl disulfide, diprenyl disulfide, 3-methyl-2-buten-1-yl thiolacetate, 3-methyl-1-[(3-methyl-2-buten-1-yl)sulfanyl]-2-butene, prenylmethylthiol (1-(methylsulfanyl)-3-methyl-2-butene), prenyl thioacetate, thiogeraniol, dimethyl sulfide, or a combination of any two or more thereof, and a primary terpene compound selected from the group consisting of myrcene, β-caryophyllene, limonene, α-pinene, β-pinene, valencene, ocimene, terpinolene, or a combination of any two or more thereof.

Compositions and methods of manufacture for an extended time-release fragrance comprising volatile organic compounds. A composition of the disclosure includes an effective amount of a volatile organic compound for providing a fragrance that can be sensed by a user and fractionated coconut oil comprising caprylic acid and capric acid.

An edible composition, an aerosol composition, a flavor composition, a fragrance composition, or an inhalable composition includes an organosulfur compound such as prenyl mercaptan, 2-methylthiophene, 3-methylthiophene, dimethyl disulfide, diprenyl disulfide, 3-methyl-2-buten-1-yl thiolacetate, 3-methyl-1-[(3-methyl-2-buten-1-yl)sulfanyl]-2-butene, prenylmethylthiol (1-(methylsulfanyl)-3-methyl-2-butene), prenyl thioacetate, thiogeraniol, dimethyl sulfide, or a combination of any two or more thereof, and a primary terpene compound selected from the group consisting of myrcene, β-caryophyllene, limonene, α-pinene, β-pinene, valencene, ocimene, terpinolene, or a combination of any two or more thereof.

The present invention relates to a method of conferring, improving, enhancing or modifying the freshness of a perfuming composition, the method comprising the step of adding at least one pro-perfume compound to the perfuming composition. The present invention further concerns a perfumed composition comprising at least one pro-perfume compound and at least one perfuming composition, as well as a perfumed consumer product comprising said perfumed composition. The present invention is further directed to the use of least one pro-perfume compound to confer, improve, enhance or modify the freshness of a perfuming composition.

The present invention relates to the field of perfumery. More particularly, it concerns compounds comprising at least one β-thio carbonyl or nitrile moiety capable of liberating an active molecule selected from an α,β-unsaturated ketone, aldehyde or nitrile. The present invention concerns also the use of said compounds in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds. (I) wherein: a) m represents an integer from 1 to 6; b) Pro represents a hydrogen atom or a group susceptible of generating an odoriferous α,β-unsaturated ketone, aldehyde or nitrile and is represented by the formulae (II) or (II′) in which the wavy line indicates the location of the bond between said Pro and the sulfur atom S; and at least one of the Pro groups is of the formula (II) or (II′). ##STR00001##
