The invention relates to human beings and their hundreds of active olfactory receptor genes which are devoted to detecting thousands of different fragrance molecules in the atmosphere. The influence of fragrances on the psycho physiological activities of human beings have been known for a long time in the cosmetic industries. These human senses play an important role in the physiological effects of fragrance delivery systems. Aromatic electrophysiological studies have revealed that aromatic fragrance delivery affect brain activities and cognitive functions which can be measured by an electroencephalograph (EEG). The patent submitted formula below infused with the claimed delivery system submitted below have been found to produce low levels of EEG temporal measures of responses in the central nervous system suggesting a significant role of a aromatic olfactory stimulation in the alteration of cognitive, mood and social behavior in retrospect the delivery system increased by 100 percent the alluring properties of the ingredients in the claim.

The present disclosure is directed to the synthesis and application of undecavertol derivatives having unique and desired flavor and/or fragrant characteristics. The compounds of the present disclosure can be employed alone or incorporated as fragrance or flavor ingredients in fragrance or flavor compositions. The present disclosure is also directed to consumer products comprising such derivatives and/or fragrance or flavor compositions.

A freshening composition is provided. The freshening composition includes about 0.02 wt. % to about 1.0 wt. %, based on the weight of the composition, of a sulfur-containing pro-perfume. The freshening composition further includes about 0.2 wt. % to about 1.4 wt. %, based on the weight of the composition, of a perfume mixture, the perfume mixture comprising at least one perfume material selected from the group consisting of: 3-(1,3-Benzodioxol-5-yl)-2-methylpropanal, canthoxal, vanillin, ethyl vanillin, citral, ligustral, cinnamic aldehydes, and combinations thereof. The freshening composition also includes a carrier.

A composition of matter comprising a) at least one compound of formula ##STR00001## in the form of any one of its isomers or a mixture thereof; wherein R.sup.1 represents a hydrogen atom or a C.sub.1-2 alkyl group; and R represents a group of formula CH.sub.2C(Me).sub.2OH; with R being, relative to position 1, a meta, a para substituent of the aromatic ring or a mixture thereof; and b) at least one compound of formula ##STR00002## in the form of any one of its isomers or a mixture thereof; wherein R.sup.1 and R have the same meaning as defined in formula (I);
their uses as perfuming ingredients as well as perfuming composition and consumer products including such a composition of matter and a process to prepare the composition.

The present invention relates to a synthetic composition which may be used to simulate a tobacco aroma. The composition comprises two or more of components A, B, C, D and/or E. As a result of providing a synthetic composition which may be used to simulate a tobacco aroma, it is possible to provide a more simple composition compared to tobacco extracts.

The present disclosure is directed to the synthesis and application of undecavertol derivatives having unique and desired flavor and/or fragrant characteristics. The compounds of the present disclosure can be employed alone or incorporated as fragrance or flavor ingredients in fragrance or flavor compositions. The present disclosure is also directed to consumer products comprising such derivatives and/or fragrance or flavor compositions.

The present disclosure is directed to the synthesis and application of ethyl linalool derivatives having unique and desired flavor and/or fragrance characteristics. The compounds of the present disclosure can be employed alone or incorporated as fragrance or flavor ingredients in fragrance or flavor compositions. The present disclosure is also directed to consumer products comprising such derivatives and/or fragrance or flavor compositions.

The present invention is an ethyl vanillin and/or vanillin friable shell-core microcapsule composition prepared by combining ethyl vanillin or vanillin with preformed friable shell-core microcapsules for a time sufficient for the ethyl vanillin or vanillin and microencapsulates to interact. Wash off consumer products and a method for depositing ethyl vanillin or vanillin on a surface are also provided.

The present invention relates to freshening compositions, devices comprising same and methods of using same for freshening the atmosphere, the air or surfaces. Also provided are methods for manufacturing the freshening compositions and devices comprising same. Disclosed are non-glycol ether liquid freshening compositions comprising a fragrance release modulator. A freshening composition of this invention may comprise (i) from about 0.1 wt % to about 95 wt % perfume raw materials, (ii) from about 0.01 wt % to about 90 wt % fragrance release modulator, and (iii) from about 1.0 wt % to about 95 wt % solvents, diluents or a mixture thereof. Disclosed are passive and active air or surface freshening products comprising a freshening composition of the present invention that allow controlled and customized release of the freshening composition to the atmosphere, air, or onto surfaces. The addition of a fragrance release modulator to formulate a freshening composition of the present invention allows the modulation of the release of the freshening composition.

The present invention relates to freshening compositions and devices comprising same that comprise a composition having a viscosity of from about 1 mPa.Math.s to about 50,000 mPa.Math.s comprising malodor reduction compositions and methods of making and using such compositions. The disclosed malodor reduction compositions do not unduely interfere with the scent of the freshening compositions and devices that comprise such technologies and the perfumed or unperfumed situs that is treated with such freshening compositions and devices.
