Compounds of Formula (I), in which the dotted lines indicate the position of single or double bonds, R1 represents a radical belonging to a fragrant alcohol of the formula R1OH, X represents a nucleophilic group selected from the group consisting of -OH, =O, -NH2 or -NHR3, R3 representing a C1 to C6 straight-chain or branched hydrocarbon radical, saturated or unsaturated, or an aliphatic or aromatic ring having 5 or 6 carbon atoms, m and n define whole numbers within the range 0 to 2 such that the sum m + n is equal to 1 or 2, p defines a whole number with a value of 0 or 1, each of the symbols R2, R4, R5, R6, R7, taken independently, represents a hydrogen atom, a C1 to C4 straight-chain or branched hydrocarbon radical, saturated or unsaturated, optionally substituted and, taken two by two, they can form aromatic or aliphatic monocyclic, bicyclic or tricyclic substances with the carbon atoms to which they are bound, are compounds capable of releasing a fragrant alcohol of the formula R1OH upon hydrolysis of the ester bond.
摘要:
The invention describes a process for the preparation of a granular delivery system particularly useful for the controlled release of flavouring or perfuming ingredients, which process comprises the steps of forming a concentrated, highly viscous emulsion of the active compound to be encapsulated, blending the latter with a hydrophilic polymer in an extruder and shaping it into a granular free flowing solid at usual storage temperatures. The process of the invention is particularly appropriate for the encapsulation of volatile molecules as it avoids any dehydration step before or after extrusion.
摘要:
The present invention is drawn to a device for perfuming ambient air or closed spaces. The said device comprises water or an appropriate hydrophilic solvent containing said volatile active ingredient and an absorbing material chosen from superabsorbents, starch based systems, chemically modified cellulose and natural gum and which are capable of forming a gel with water or said hydrophilic solvent, both components being adapted to be mixed with each other in order to achieve the diffusion of said volatile ingredient from the said gel. The components are mixed with each other to form said gel from which the perfume or a deodorizing or sanitizing agent, or an insect repellent, diffuses uniformly and over a prolonged period of time into the surrounding air.
摘要:
The present invention relates to the perfumery industry. It concerns more particularly a compound of formula (I) wherein the index m represents 0 or 1, R represents a hydrogen atom, or a methyl or acetyl group, R 1 , R 2 and R 4 represent a hydrogen atom or a methyl group, R 3 represents a hydrogen atom, or a methyl or ethyl group, and two, three or four of all the R 1 , R 2 , R 3 and R 4 representing simultaneously a group containing at least a carbon atom, and the wavy and dotted lines represent a double bond, in which case n represents 0; or the wavy line represents a single bond, in which case the index n represents 1, and the dotted line represents a single or double bond; in the form of any one of its optical isomers or diastereomers or of a mixture thereof. The invention also relates to the use of the invention compounds as perfuming ingredients, able to impart a woody and/or aromatic, as well as to the perfumed articles or perfuming compositions comprising as active ingredient a compound of formula (I).
摘要:
According to the invention, the device for diffusing aromas comprises a bottle (10) containing the aromatic product (11) to be diffused in a liquid state, said bottle being removably mounted beneath a device body (1). Said body has an inner chamber (2) which communicates with said bottle (10) in the operating position; and horizontal entrance/exit channels (3, 4) which are connected to a pressurized air circuit which opens into said chamber. A diffusion screen (7) is arranged inside the inner chamber (2), perpendicularly to the axis of said horizontal passages, and a capillary element (6) connects the liquid (11) contained in the bottle (10) to said diffusion screen (7).
摘要:
A compound of formula wherein the symbol R' represents a linear or branched, unsaturated or saturated hydrocarbon group having from 1 to 5 carbon atoms; R 1 , R 2 , R 3 , R 4 and R 5 represent, independently of each other, a hydrogen atom, a methyl, an ethyl or a methoxy group ; R 6 and R 7 represent, independently of each other, a hydrogen atom, a methyl, ethyl, n -propyl or iso -propyl group ; and wherein R 5 and R 6 , when taken together with the carbon atoms to which they are bound, may form a six-membered ring, is useful as perfuming ingredient for the preparation of perfuming compositions and perfumed products, to which it imparts odor notes of the floral and indol type without coloring problems in the final product.
