Described herein is a fragrance delivery system including a perfume oil and a carrier material, where the perfume oil includes at least one pro-perfume compound and where the perfume oil is dispersed in or absorbed within the carrier material. Also described herein are compositions and perfumed products including the same.

A surface treatment composition including from about 1×10.sup.2 to about 1×10.sup.9 CFU/g of the composition of Bacillus spores; from about 0.01% to about 15% by weight of the composition of a pro-perfume material including a glycoside, a phosphate acid ester, an amino-acid derivative, a carboxylic acid derivative, or a combination thereof; and a perfume.

Described herein are compounds of formula (I) that are able to provide a long-lasting or substantive odor, in particular floral and/or fruity odor, to the environment. Also described herein is a method of imparting a long-lasting odor, in particular a fresh green, floral and/or fruity odor, to surfaces, such as hard surfaces, fabric, skin or hair. Also described herein are a method of using said compounds in perfumery and perfuming compositions or perfumed articles including the compounds described herein.

Suggested is fragrance composition comprising or consisting of a selection of specific nitriles showing improved stability against decomposition and discoloration.

There is provided the use of selenide derivatives of fragrance compounds comprising an α,β-unsaturated aldehyde moiety, an α,β-unsaturated ketone moiety, an α,β-unsaturated ester moiety, an α,β-unsaturated lactone moiety or an α,β-unsaturated carboxylic acid moiety in consumer products. There are further provided methods for the synthesis of selenide derivatives, certain selenide derivatives, consumer products comprising the selenide derivatives and methods of perfuming an article or surface using such derivatives.

The present application relates to silicone compounds, compositions, packaged products and displays comprising such silicone compounds, and processes for making and using such compositions, packaged products and displays comprising such compositions. Such compositions have improved deposition and retention properties that may impart improved benefit characteristics to a composition and/or situs yet which changes its hydrophilicity/charge when desired.

Such compositions have improved deposition and retention properties that may impart improved benefit characteristics to a composition and/or situs yet which changes its hydrophilicity/charge and/or demonstrates cleavage of the functionalized silicone's functionalization when desired.

A fragrance precursor of 3-(4-isobutyl-2-methyl phenyl)propanal, comprising at least an enamine and/or an aminal as reaction product of 3-(4-isobutyl-2-methylphenyl)propanal (compound according to formula (I)) and a primary and/or secondary amine

##STR00001##

useful as a perfume ingredient.

A fragrance precursor represented by the formula 1

##STR00001##

wherein

X and Y together represent a double bond to a carbon atom bearing R.sub.1 and R.sub.2, with R.sub.1═H, methyl, acetyl or C.sub.1—C.sub.3 alkoxycarbonyl (e.g. ethoxycarbonyl); and R2=phenyl optionally substituted with up to 3 (i.e. 0, 1, 2 or 3) groups selected from C.sub.1—C.sub.4 alkyl (e.g. methyl, ethyl, iso-propyl, tert-butyl), vinyl, hydroxy, C.sub.1—C.sub.3 alkoxy (e.g. ethoxy), and —O—CH.sub.2—O—, e.g. R.sub.2 is benzo[d][1,3]dioxol-5-yl, 4-methylphenyl, 4-methoxyphenyl, 4-vinylphenyl or 3-ethoxy-4-hydroxyphenyl or

R2=naphthyl, (naphthyl) methyl, 1,1,2,4,4,8-hexamethyl-1,2,3,4-tetrahydronaphthalen-7-yl, or 1,1,2,4,4,-penta methyl-1,2,3,4-tetrahydronaphthalen-7-yl or

R2=COR3, wherein R3 is H, C1-C10 alkoxy (e.g. ethoxy, 1-(3,3-dimethylcyclohexyl)ethoxy), C1-C4 alkyl (e.g. methyl, ethyl, propyl, iso-propyl, tert-butyl), e.g. R2 is formyl, acetyl, ethoxycarbonyl, 1-(3,3-dimethylcyclohexyl)ethoxycarbonyl; or wherein

X is OR4, with R4 being H or alkyl, and

Y is OR5, with R5 being alkyl,

useful as a perfume ingredient.

The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile α-ketoacid or α-ketoester capable of generating a gas upon exposure to light. The gas is able to cause an extension or the breaking of the microcapsule allowing the release of the oil phase and thus increasing the long-lastingness of the odor perception. The present invention concerns also the use of said microcapsules in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's microcapsules to provide a prolonged release of fragrant molecules.
