Pro-benefit-agent compounds having heterocyclic moieties that include a benefit agent fragment derived from benefit agents, such as perfume raw materials, that include an aldehyde moiety or a ketone moiety. The pro-benefit-agent compounds may be derived from modified amino acids. Related treatment compositions, premix compositions, precursor compounds, and methods of making and using such materials and compositions.

The present invention relates to the field of perfumery. More particularly, it relates to compounds of formula (I) that are able to provide a long-lasting or substantive odor to the environment. Moreover, the present invention relates to a method of imparting a long-lasting odor to environment or to surfaces, such as hard surfaces, fabric, skin or hair. Furthermore, the present invention relates to the use of said compounds in perfumery, as well as the perfuming compositions or perfumed articles comprising the invention’s compounds.

A γ-caprolactone precursor-aroma compound and a preparation method and uses thereof are disclosed. The preparation method specifically includes: dissolving γ-caprolactone in a sufficient amount of a solvent, adding an alkali at −78° C. to 0° C., stirring the resulting mixture to allow a reaction for 20 min or more, adding 2-acetylpyridine, further stirring at −78° C. to 0° C. to allow a reaction for 30 min or more, quenching the reaction, and finally subjecting the resulting reaction system to post-treatment, separation, and purification to obtain the target lactone precursor-aroma compound. The precursor-aroma compound of the present disclosure has stable properties in a normal temperature environment, can uniformly release an aroma under heating, increase and enrich the types of lactone fragrances, broaden an application range of lactone fragrances and acylpyridines, and overcome the defects of lactone and acylpyridine themselves, such as high volatility, small threshold, strong smell, and easy loss during processing.

The present application relates to antiperspirant compositions comprising nitrogen-based and/or oxygen based perfume raw materials, and methods for making and using the antiperspirant compositions.

The present invention relates to the field of perfumery. More particularly, it concerns short chain β-sulfur carbonyl moieties capable of liberating an active molecule, such as a perfuming α,β-unsaturated ketone or aldehyde. 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.

The present application relates to fragrance compositions comprising perfume raw materials that resist fragrance habituation, and methods for making and using the fragrance compositions.

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.
