Description

ENCAPSULATED PROPERFUME COMPOUNDS Description of the Invention The present invention relates to a fragrance delivery system comprising a perfumed oil and a carrier material, wherein the perfumed oil comprises at least one properfume compound and wherein the perfumed oil is dispersed or absorbed into the carrier material, as well as perfume compositions and perfumed consumer products comprising it. Properfume compounds are known to a person experienced in the technique and provide a release of a perfume ingredient, in particular an olfactory perfume ingredient, upon activation by an external stimulus, such as contact with moisture and / or exposure to light and / or increased temperature and / or an oxidative environment, and some control of the fragrance release kinetics to induce sensory effects by sequential release. In certain applications, such as washing machine / laundry powder and hand washing powder, perfumery ingredients such as, among others, properfume compounds tend to be stored for long periods of time and / or under adverse conditions, such as exposure to light and / or high temperatures and / or in Ref. 319138 an oxidative environment, so that the perfume ingredient degrades and the properfume compound becomes the olfactory perfume ingredient prematurely without being in contact with the intended place, such as a fabric. WO 03 / 049666 A2 describes certain properfume compounds but does not describe or suggest their use in a fragrance delivery system according to the present invention. There is a need to provide a fragrance delivery system that provides improved stability for properfume compounds, particularly in powder detergents, and / or additional control over the fragrance release kinetics of properfume compounds after application. The prior art does not describe or suggest a fragrance delivery system according to the present invention that provides improved stability for properfume compounds, particularly in solid cleaning products such as powdered detergents, and / or that provides additional control of the fragrance release kinetics of properfume compounds after application, for example, to induce sensory effects by sequential release. The present invention relates to a fragrance delivery system comprising - a perfume oil and - a carrier material, wherein the perfume oil comprises at least one properfume compound and wherein the perfume oil is dispersed or absorbed within the carrier material. A fragrance delivery system is understood to be the encapsulation of fragrances or perfumes in carrier materials to provide protection against aging, enhance the impact during use, and provide sustained release of the substrates. By dispersed or absorbed within, it is understood that the perfume is trapped within a matrix formed by the carrier material. Conversely, a microcapsule or core-shell microcapsule refers to a delivery system comprising an oil-based core of a hydrophobic active ingredient encapsulated by a polymeric shell. In other words, the delivery system of the present invention is not in the form of a core-shell microcapsule but in the form of a granule, also called a particle. In a preferred embodiment, the fragrance delivery system is a solid fragrance delivery system. Typically, a particle has a volume-weighted average particle size of 5 to 500 pm, preferably 6 to 300 pm, and more preferably 10 to 100 pm. The volume-weighted average particle size of the particles can be measured using optical microscopy and light scattering (Mastersizer 3000, Malvern). According to the present invention, the fragrance delivery system comprises a perfume. By perfume oil (or simply perfume) we mean an ingredient or composition that is a liquid at approximately 20°C. According to any of the above definitions, perfume oil may also be called perfume and can be a single fragrance ingredient or a mixture of ingredients in the form of a perfume composition. The term fragrance ingredient refers to a compound used as an active ingredient in perfume preparations or compositions to impart a pleasing effect. In other words, for a compound to be considered a fragrance ingredient, it must be recognized by someone skilled in perfumery as capable of positively or pleasantly imparting or modifying the scent of a composition, and not merely as having a scent.The nature and type of fragrance co-ingredients do not warrant a more detailed description here, which in any case would not be exhaustive. A person experienced in the technique can select them based on their general knowledge and according to the intended use or application and the desired organoleptic effect. Generally speaking, these fragrance co-ingredients belong to chemical classes as varied as alcohols, lactones, aldehydes, ketones, esters, ethers, acetates, nitriles, terpenoids, nitrogenous or sulfurous heterocyclic compounds, and essential oils. Fragrance co-ingredients can be of natural or synthetic origin. The fragrance ingredient itself can also be of natural or synthetic origin. Many of these fragrance ingredients are listed in reference texts such as S. Arctander's book, *Perfume and Flavor Chemicals*, 1969, Montclair, New Jersey, USA., or its more recent versions, or in other works of a similar nature, as well as in the abundant bibliography of patents in the field of perfumery. In particular, perfume oil may also include solvents and adjuvants commonly used in perfumery. Solvents commonly used in perfumery are understood here to be materials that are practically neutral from a perfumery point of view, that is, they do not significantly alter the organoleptic properties of the perfume ingredients and are generally not miscible with water, that is, they have a solubility in water below 1%. 10%, or even below 5%. Solvents commonly used in perfumery, such as dipropylene glycol, diethyl phthalate, isopropyl myristate, benzyl benzoate, 2-(2-ethoxyethoxy)-1-ethanol or ethyl citrate, limonene or other terpenes, isoparaffins such as those known under the registered trademark Isopar® (origin: Exxon Chemical) or glycol ethers and glycol ether esters such as those known under the trade name Dowanol® (origin: Dow Chemical Company), are suitable solvents for the purposes of the invention. By adjuvants currently used in perfumery, we mean an ingredient capable of imparting additional benefits such as color, chemical stability, etc. A detailed description of the nature and type of adjuvant commonly used in perfume bases cannot be exhaustive, but it should be mentioned that the ingredients are well known to a person experienced in the technique. According to any of the foregoing embodiments, the perfume oil may be partially encapsulated in a core-shell microcapsule. The nature of the polymeric shell of the microcapsules of the invention may vary. By way of non-limiting examples, the shell may be made of a material selected from the group consisting of polyurea, polyurethane, polyamide, polyacrylate, polysiloxane, polycarbonate, polysulfonamide, urea-formaldehyde, melamine-formaldehyde resin, melamine-formaldehyde resin crosslinked with polyisocyanate or aromatic polyols, melamine-urea resin, melamine-glyoxal resin, gelatin / gum arabic shell wall, and mixtures thereof. According to the present invention, the perfume oil comprises at least one properfume compound. Properfume compounds are known to a person experienced in the technique and provide a release of a perfume ingredient, in particular an olfactory perfume ingredient, when activated by an external stimulus, such as contact with moisture and / or exposure to light and / or increased temperature and / or an oxidative environment, and provide some control of the fragrance release kinetics to induce sensory effects through sequential release. In a preferred embodiment, the perfume oil comprises from 1 to 5 properfume compounds, more preferably from 1 to 3 properfume compounds. Therefore, it is understood that the perfume oil comprises from 1 to 5 structurally different properfume compounds, more preferably from 1 to 3 structurally different properfume compounds. In a preferred embodiment, the properfume compound according to the present invention is a storage-labile properfume compound. Storage labile means that, during extended storage in the perfumed consumer product, the properfume compound breaks down or degrades over time at a rate considered unacceptable to provide a long-term olfactory effect, thus preventing its effective use. In a preferred embodiment, the properfume compound is a thermolabile, photolabile, moisture-labile, enzymatically labile and / or oxygen-labile properfume compound, more preferably a temperature-labile, moisture-labile and / or oxygen-labile properfume compound, even more preferably a temperature-labile and / or oxygen-labile properfume compound, and most preferably an oxygen-labile properfume compound.

The use of the aldol derivative is particularly interesting for the synthesis of all compounds of formula (I) where X represents, for example, a carboxylic functional group, sulfonate, sulfate, carbonate, phosphate, borate, and silicate. On the other hand, the direct use of the odoriferous molecule as a starting material is particularly interesting for the synthesis of all compounds of formula (I) where X represents, for example, an ether, thioether, or even a thiocarboxylic derivative. Polymeric materials can also be obtained by polymerizing a monomer to which a (-G-)n[-XP]m moiety has been previously grafted. Polymerization can also be carried out in the presence of other monomeric units bearing a different (-G-)n[-XP]m moiety.

Furthermore, the present invention relates to a perfume composition comprising - a fragrance delivery system, as defined above; at least one ingredient selected from the group consisting of a perfume carrier, a perfume co-ingredient, or a mixture thereof; and - optionally, a perfumery adjuvant. For the purposes of this document, a fragrance carrier is defined as a material that is practically neutral from a perfumery standpoint, meaning that it does not significantly alter the organoleptic properties of the fragrance ingredients. The carrier may be a liquid or a solid, preferably a solid. Examples of liquid carriers include, but are not limited to, an emulsifying system (i.e., a solvent and a surfactant) or a solvent commonly used in perfumery. A detailed description of the nature and types of solvents commonly used in perfumery cannot be exhaustive. However, examples of non-limiting solvents include dipropylene glycol, diethyl phthalate, isopropyl myristate, Abalin, benzyl benzoate, 2-(2-ethoxyethoxy)-1-ethanol, and triethyl citrate, which are among the most commonly used. Naturally derived solvents such as glycerol or various vegetable oils, such as palm oil, sunflower oil, and linseed oil, can also be cited.For compositions comprising both a perfume carrier and a perfume base, other suitable perfume carriers, other than those previously specified, may also be ethanol, water / ethanol mixtures, limonene or other terpenes, isoparaffins such as those known under the registered trademark Isopar® (origin: Exxon Chemical) or glycol ethers and glycol ether esters such as those known under the trade name Dowanol® (origin: Dow Chemical Company).

Conclusions While after 4 weeks of storage at 22°C, the performance on dry fabrics due to the presence of the profume compound 3-(dodecylthio)-l-(2,6,6-trimethyl-3-cyclohexen-1-yl)-1-butanone is slightly weaker when the perfume was added directly to the powdered detergent as a free oil rather than encapsulated, the difference is striking after high-temperature storage. After 4 weeks of storing the detergent at 40°C, the performance on dry fabrics of perfume A added as a free oil is much lower than if perfume A had been encapsulated in a starch matrix. The performance on dry fabrics of perfume A_ added as free oil is significantly lower after 4 weeks of storage of the detergent at 40°C versus 22°C, whereas, if perfume A had been encapsulated in a starch matrix, the drop in performance between 22°C and 40°C is very low.

Conclusion The loss of 4-(dodecylthio)-4-(2,6,6-trimethyl-1 / 2-cyclohexen-l-yl)-2-butanone after storage in a powdered detergent is almost complete, even after two weeks, when used in the free oil form under stressed storage conditions at 40°C. The stability of 4-(dodecylthio)-4-(2,6,6-trimethyl-1 / 2-cyclohexen-l-yl)-2-butanone is greatly improved when protected in a starch matrix. The loss of 4-(dodecylthio)-4-(2,6,6-trimethyl-1 / 2-cyclohexen-l-yl)-2-butanone in powdered detergent with fragrance B encapsulated in a starch matrix is ​​much less pronounced compared to fragrance B added to the detergent as a free oil. After two weeks of storage, there is practically no loss, and after a further two weeks, the observed loss is only 32%. Example 6: Olfactory performance of 4-(dodecylthio)-4(2,6,6-trimethyl-1 / 2-cyclohexen-1-yl)-2-butanone in powdered detergent a. Composition A typical powder bleaching composition contains, among other ingredients: 15-30% oxygen-based bleaching agents, 5-15% anionic surfactants, zeolites, less than 5% non-ionic surfactants, phosphonates, polycarboxylates, and optical brightener. b. Protocol The fabrics (2.0 kg of cotton terry towels) were washed at 37°C in a standard European horizontal-axis washing machine (Miele Novotronic W 900-79 CH) using samples stored for 2 weeks at 37°C. After washing, the fabrics were line-dried overnight before a panel of 20 trained panelists assessed the odor intensity of the cotton towels. The panelists were asked to rate the odor intensity of the towels on a scale of 1 to 7, where 1 corresponds to odorless and 7 to a very strong odor. C. Test Results The results are shown in Table 8 below.

Ingredients Part PEG 4000 - 7500 68 Dextrose 26 Perfume B 6 26% dextrose was added to the PEG base, and the mixture was melted at 80°C. Next, 6% perfume E was added and mixed in. Finally, lipase was added in granular or liquid form and gently mixed in to maintain the integrity of the lipase granules. The mixture was then pelletized as it cooled by pouring a thin film of the molten mixture onto a flat surface and cutting it into smaller pieces after solidification. The sodium carbonate mixture was prepared in accordance with P&G patent US 2003 / 0171250 Al. 80 g of Neodol 91-8 dispersant (966461) were heated to 70°C in a water bath. 20 g of perfume oil were added to the water bath and then mixed with Ultraturrax at 9000 RPM for 2 min. This mixture was then returned to the water bath at 70°C for 1-2 min to obtain a clear liquid. Next, this κ c ι\ c The liquid was poured into 200 g of fine sodium carbonate (Solvay sodium carbonate), carefully controlling the weight added: 97 g of the solution were poured into the sodium carbonate. The mixture was then stirred with a glass rod and agitated for 10 min in a Turbula mixer (in a 500 ml glass bottle with a twist-off stopper). c. Conclusions After 2 weeks of storage of the detergent at 37°C, the performance on dry fabrics of perfume E added as a free oil was perceived to be on par with that administered through the carrier sodium carbonate mixture, and both scored much lower than if perfume E had been encapsulated in a starch matrix or contained in a PEG granule base.
