The present invention relates to the field of perfumery. More particularly, it concerns perfuming composition comprising at least one profragrance and at least one perfuming ingredient having a LogP above 3. Following what is mentioned herein, the invention's 5 perfuming composition as a part of a perfuming composition or a perfumed consumer product and the use of the invention's perfuming composition are also objects of the invention.

A culture product comprising a large quantity of ethyl benzoate and has a more complex and fresher fruity aroma than a chemically synthesized product. The culture product is obtained by culturing a microorganism belonging to the genus Wickerhamomyces in a milk component-containing culture medium.

A perfume composition having controlled release of phytoncides in an atmosphere in order to generate an air condition resembling the air environment of a forest is provided. The perfume composition includes a) at least about 0.6% by weight of at least one phytoncide; and b) a perfume mixture including (i) at least one solvent; and (ii) at least one fragrance ingredient. At least about 25% by weight of the at least one phytoncide is selected from the group consisting of pinene alpha, pinene beta and combinations thereof.

The present invention discloses a thermosensitive nanocapsule and a preparing method thereof. The thermosensitive nanocapsule includes core materials and wall materials. The preparing method includes: first, making water phase and oil phase respectively, forming microemulsion by means of high speed shearing after mixing, and forming nanoemulsion via ultrasonic treatment or high pressure homogenization; then adding nitrogen to the emulsion and carrying out the reaction under a temperature of 40-80 C. for 3-4 hrs in the nitrogen atmosphere; finally obtaining the thermosensitive nanocapsule with an embedding rate of 90-94%, a particle size of less than 150 nm and a dimension polydispersity index of 0.09-0.17. In present invention, the monomer that forms the wall material of the nanocapsules is made from common biological materials, and has a good biocompatibility. The wall material has a temperature sensitivity, and can control the delayed release of core material by adjusting temperature.

The present invention relates to a method for releasing an unsaturated aldehyde or ketone represented by the general formula (2) by irradiating the compound represented by the general formula (1) with light, in which the compound represented by the general formula (1) is used as a flavor or fragrance precursor: ##STR00001##

Photolabile pro-fragrances may include the ketones of Formula (I) ##STR00001## Such compounds may be used in detergents, cleaning agents, cosmetic agents, air-care agents, and combinations thereof. The photolabile pro-fragrances may create a long-lasting fragrance on surfaces or in a room using the aforementioned pro-fragrances.

A system of and for extraction or removal of phytochemicals from plants, including those of the plant family Cannabaceae sensu stricto. More specifically, a system for extracting essential oils from plants, such as cannabis, without the use of a solvent.

The present invention relates to a delivery system based on photosensitive acetal or ketal compounds capable of liberating upon exposure to light an active volatile carbonyl compound in a controlled manner from a surface into the surrounding. The delivery system can be used to release active substances such as flavors, fragrances, malodor counteractants, insect attractants or insect repellents. The invention also relates to the use of said acetal or ketal compounds in perfumery, as well as in perfuming compositions or perfumed consumer articles.

Provided herein is a rice husk particles wherein at least 90%, by weight, of the total weight of the particles, has a diameter less than 25 m.

The present invention relates to a method for releasing an unsaturated aldehyde or ketone represented by the general formula (2) by irradiating the compound represented by the general formula (1) with light, in which the compound represented by the general formula (1) is used as a flavor or fragrance precursor:

##STR00001##
