The invention further relates to a new mixture comprising or consisting of one or more stereoisomers of the compound of formula (I) as described herein and two or more stereoisomers of the compound of formula (II) as described herein with a weight ratio of the stereoisomers of the compounds of formula (II) as described herein, fragrance compositions comprising or consisting of a mixture as described herein, perfumed products containing mixtures or fragrance composition as described herein, and a process for modifying and/or enhancing the lily of the valley scent of a compound of formula (II) as described herein, respectively for preparing a perfumed product as described herein.

A system for purifying cannabis miscella is provided comprising a feed tank enabled to store the miscealla derived from cannabis extraction, a plurality of optical sensor modules, at least one valve, an ultrafiltration membrane module; and at least one pump. Wherein a closed system enabled to maintain a positive or negative pressure created by the at least one pump, enabling moving a flow of the miscealla through the system, one optical sensor is positioned upstream and downstream from the ultrafiltration membrane, the at least one valve is positioned between ultrafiltration membrane and an outlet, and a level of opening the valve creates different levels of back pressure based on readings from the optical sensors.

The present invention provides personal care compositions comprising a carrier and a mixture of essential oil components having specific levels of eucalyptol, terpene materials and auxiliary fragrance materials. The compositions herein gentle to skin and have a fragrance and activity similar if the composition were made using the pure extracted essential oil.

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 invention relates to freshening compositions, devices comprising same and methods of using and manufacturing same. A freshening composition of this invention may comprise (i) from about 0.1 wt % to about 95 wt % perfume raw material, (ii) from about 0.01 wt % to about 90 wt % fragrance release modulator, and (iii) from about 1.0 wt % to about 95 wt % solvent. Some freshening composition further comprise an ingredient having a functional activity. Disclosed are passive and active air or surface freshening products comprising a freshening composition that allow controlled and customized release of the freshening composition or of a component thereof into or onto an environment. 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 or of a component thereof.

The use as fragrance ingredient of 4-methylene-2-(2-methylprop-1-enyl)-tetrahydropyran.

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 invention relates to novel compounds and their use as malodor counteractant materials.
