Countryside

The object of the invention disclosed herein refers to perfume embodiments that include one or more of a perfume oil or essential oil, one or more alcohols, a stabilizing agent and, in some embodiments, a stable suspension of particles. .

Background

Humans have applied fragrances for thousands of years. The ancient Egyptians, considered among the first users, applied scented oil and incense. Some of the first chemists known to make perfume and used the distillation procedure to extract essences from natural materials such as flowers. Other essences extraction procedures 25 have included maceration and solvent extraction. During the course of the history of mankind, essences have been a reflection of the cultures that created them. A horrible example was a fragrance called "Parfum à la Guillotine", created during the French revolution. The trend that the fragrance reflects greater culture continues today.

Embodiments of the invention are disclosed herein for a hydroalcoholic perfume 20 having a viscosity in a range of 30 to 1000 centipoises, including the embodiments of water-based hydroalcoholic perfume, one or more alcohols, a fragrance oil in a concentration It can be up to 20% by weight and one or more essences. Embodiments of the invention also include stabilizing agent to stabilize all constituents of the fragrance formulation and to promote a fine mist spray pattern embodiment when the perfume is sprayed through a spray pump. Although a viscosity range of 30 to 1000 centipoise is described, it is understood that the viscosity may be higher in some embodiments. Each of the stabilizing polymers disclosed herein gives the formulation of alcohol, water, fragrance oil and material that confers fragrance, a particular rheological behavior. As a consequence, for embodiments that include a stabilizer, the specific range and mist spray pattern embodiments disclosed herein depend on the stabilizer polymer (s) employed, which are disclosed herein. 35

This fine mist spray pattern is unexpected in that it occurs throughout the spectrum of hydroalcoholic perfume formulation embodiments. The spray pattern is also unexpected in view of the high viscosity of the perfume and the high load of fragrance oil. For example, a hydroalcoholic perfume formulation, as disclosed herein, thickened with a material 5 such as Pemulen TR-2, a cross-linked acrylate / C-alkyl acrylate polymer formulation (10-30), manufactured by Lubrizol does not have a rheology adapted to obtain an embodiment of the spray mist pattern disclosed herein, as shown in FIG. 6.

Additionally, the stabilizing agent, in combination with other constituents, confers phase stability, rheological stability and particle suspension stability, for perfume formulation embodiments that include particles. Some perfume formulation embodiments disclosed herein also include a stable suspension of particles in which the fragrance oil and a stable suspension impart one or more sensory experiences to a consumer.

Some perfume embodiments confer sensory experiences directed at one or more of the vision or appearance of the perfume such as crystalline transparency, especially when the perfume is in a transparent, colorless container, such as a bottle. Other embodiments of perfume have flashes from bright particles that reflect light when they are in the transparent container. For other perfume embodiments, the fragrances or essences confer sensations experienced by the consumer after inhaling the essence or the fragrance, and the sensation of the perfume after the application of the perfume formulation on the skin. Other embodiments of perfume confer numerous sensory experiences or confer a combination of sensory experience and non-sensory benefits.

The perfume formulation embodiments disclosed herein include one or more alcohols, one or more fragrance oils in concentrations of 30 to 20% by weight, one or more constituents that confer essence, water and one or more stabilizing agents. The one or more stabilizing agents give the perfume desirable mist spray pattern embodiments when sprayed from a pump sprayer having a higher than normal prior compression spring. For some embodiments of perfume formulation that include particles, the stabilizing agent stabilizes the suspension of particles in the

formulation of alcohol, fragrance oil and water. In some embodiments, the particles have a concentration of less than one percent by weight.

The perfume formulation embodiments described herein are surprising and unexpected because they maintain long-term stability with a very high concentration of fragrance oils and have a desirable mist spray pattern when sprayed through a sprayer. which has a higher compression spring than normal. These characteristics also exist in perfume embodiments that include particles.

In the hydroalcoholic formulation embodiments disclosed herein, water is present in a concentration of up to 25% by weight and the one or more alcohols are present in a concentration range of about 45% to 80% by weight. In some embodiments, the alcohol is an alcoholic grade ethanol of 190 SDA 40 B. Any low molecular weight alcohol, such as isopropanol, can be used with or without a denaturant and with any commercially available denaturant. Some perfume embodiments also include an alcohol from C (12) to C (22) in order to reduce the evaporation of the alcohol from the perfume formulation. In some embodiments, water is demineralized water. Some perfume embodiments include a fragrance fixing complex, as disclosed in EP1715841B1, which is incorporated herein by reference. The fragrance fixing complex includes 0.01 to 10% by weight of an alcohol-soluble, hydrophobic, carboxylated acrylate / octyl acrylamide copolymer, and 0.01 to 10% by weight of a hydrolyzed jojoba ester, in which the percentages refer to the total weight of the cosmetic composition. 25

Some formulation embodiments also include fragrance oil concentrations in concentrations of up to about 20% by weight. As discussed, a stable perfume formulation that includes this high load of fragrance oil is unexpected. The stability of formulations that include both particles 30 and the high load of fragrance oil is even more unexpected.

The perfume formulation embodiments disclosed herein form a very stable gel, in some embodiments, and a thickened, stable formulation, in other embodiments. This stability is demonstrated by the stability of the rheology, the viscosity and, in some embodiments, the suspension capacity of

particles for all viscosities of perfume formulation embodiments.

In one embodiment, the particle suspension stabilizing agent employed, crosslinked polymer of ammonium acryloyl dimethyltaurate / carboxyethyl acrylate, has the trade name of Aristoflex TAC (code TRM04192), and is manufactured by Clariant of New Jersey. The Aristoflex TAC copolymer has the following chemical formula:

is hydrogen, with the proviso that the molar ratio of the structural units of formula (1) in which Q + is NH4 +, Li +, Na +, K +, Ca ++, Mg ++, Zn ++ or Al +++ and the structural units of formula (2) are from 97: 3 to 55:45, and the corresponding XCl alkylammonium chlorides possess a critical micellar concentration (CMC) <15 g / l, and

d) from 0% to 8%, preferably from 0.01% to 5%, by weight of crosslinking structural units from monomers having at least two olefinic double bonds.

The Aristoflex TAC copolymer has an average molecular weight range of 1000 to 10,000,000 UPM. The Aristoflex TAC copolymer can be used to aid in the suspension of particles. The Aristoflex copolymer can be used in transparent, low viscosity and low pH gel formulations.

The Aristoflex TAC copolymer is a preneutralized crosslinked sulfonic acid polymer that is a 100% active powder, which swells easily when added to surfactant systems. The Aristoflex TAC copolymer eliminates the loss of viscosity of low temperature surfactant solutions. The Aristoflex TAC copolymer creates a yield force and stabilizes color particles even at low concentrations, low viscosities and an acidic pH. twenty

Aristoflex TAC is used to stabilize perfume formulation embodiments that include water, alcohol in concentrations of up to about 79% by weight, fragrance and, in some embodiments, a particle suspension.

In another embodiment, a thickener such as Carbopol 980 is used as a stabilizing agent. Carbopol 980 is a crosslinked polyacrylate polymer, manufactured by Lubrizol. The chemical structure of Carbopol 980 is shown below. Other formulations that have a highly crosslinked acrylic acid polymer with the same rheological properties as Carbopol 980 include Carbopol 940 and 30 Carbopol Ultrez, manufactured by Lubrizol, and Tego Carbomer 140 and Tego Carbomer 340D, manufactured by Evonik. Carbopol 980 is used to stabilize perfume formulation embodiments that include an alcohol such as ethanol in concentrations of up to 68% by weight, fragrance oil up to 10% by weight and water in a concentration of up to about 25% in weight. Perfume formulations stabilized with Carbopol 980 give a pre-selected rheological profile

Stable and, in combination with other constituents, allows the fragrance formulation to produce a fine mist when sprayed from a pump sprayer that has a higher compression spring than normal.

Another thickener that can be used in perfume embodiments disclosed herein includes a cross-linked polyacrylate-6 polymer, which has the trade name Sepimax Zen, manufactured by Seppic, of Puteaux, France.

Another thickener that can be used in perfume embodiments disclosed herein includes Ultrathix P-100, manufactured by ISP. The Ultrathix P-100 has the following chemical structure:

Aristoflex TAC, Carbopol 980, Sepimax Zen, Ultrathix P-100 and other polymers disclosed herein may also be used, in combination with other constituents, to further maintain the suspension of particles in the perfume formulation so that the suspension does not separate and sediment, for perfume formulation embodiments that include a suspension of particles. These other components include one or more surfactants, especially for 20 perfume formulation embodiments that have a higher concentration of water.

Surfactants can be used to reduce the ethanol concentration of a

perfume realization. Surfactants include lauret sulphosuccinate disodium, alone or mixed with lauryl sulphosuccinate disodium.

In another embodiment of the invention, one or more non-ionic emulsifiers can be added to the perfume composition. Suitable non-ionic emulsifiers that can be used include hydrogenated castor oil polyethylene glycol with 2 to 200 units of polyethylene glycol, preferably PEG-40 hydrogenated castor oil and / or PEG-60 hydrogenated castor oil, polysorbate 20, polysorbate 40, polysorbate 60, olet-5, olet-10, olet-20 or PPG-1-PPG-9, glycol lauryl ether and mixtures thereof. Also, Solubilisant LRI (Sensient) and other commercial combinations developed specifically for the solubilization of fragrances can be used. In some cases, anionic and / or cationic surfactants can be used alone or in combination to solubilize the fragrance oil in the hydroalcoholic medium.

Each of these stabilizers also gives the perfume embodiments 15 disclosed herein the ability to effect a desirable spray pattern when sprayed with a spray pump having a higher than normal prior compression spring produced by the force necessary to propel the perfume through the spray nozzle. A type of spray pump having a higher compression spring than normal is obtained at 20 from Rexam SP22 + / Dose 80, obtained from Rexam PLC of Millbank, London SW1P, United Kingdom. In FIG. 1, 2, 3 and 4 desirable spray patterns are shown. These spray patterns were prepared with perfume formulations with a fragrance oil concentration of 10% by weight. Spray patterns were made by spraying the sprayer at a distance of twelve cm +/- 1 cm from a spray receiving surface. The spraying was done three times by the same person, in order to increase the contrast between the spray and the paper in order to obtain better quality images.

The spray receiving surface was paper obtained from Staples. The paper was placed vertically on a fixed metal frame. A light was placed on the back of the paper and did not go to the paper in order to increase the contrast. A camera was used to capture images of spray patterns. The camera was placed 54 cm +/- 1 cm from the paper. The camera was not used with a flash and was an SLR with autofocus. 35

Other types of particles that confer a visual effect include particles that include an interference pigment that has a multilayer structure. The interference particle core includes a flat substrate with a refractive index of less than 5 1.8.

In some embodiments, the particles are coated with a coating such as a polysaccharide. In one embodiment, the particles are hydrophilic GA black oxide particles whose surface has been treated with galactoarabinan. The particles were obtained from Color Techniques of South Plainfield, NJ, as product number GA-7403. Galactoarabinan is a polysaccharide obtained as an extraction from larch, Larix. The particle sizes of GA black oxide are in a range of 20 to 200 micrometers. Galactoarabinan coated particles are resistant to oxidation and are dispersed in a liquid with a particle suspension agent, such as Aristoflex or CARBOPOL 980.

In some perfume formulation embodiments that have a visual effect, the perfume formulation has layers of color or color gradation or opacity gradation. In particular, in some embodiments, two or more suspensions 20 of stable particles are formed as part of a perfume formulation, included in a container, each suspension being formed depending on the size of the particles, the density of the particles, the charge of surface or a combination of these particle characteristics. The two or more suspensions are stabilized in separate and different areas of the fragrance formulation, within the storage bottle. In these embodiments, the consumer sees a perfume that has separate layers of color or gradations thereof or of different colors or opacity or other types of visual appearances inside the container. The layers or gradations or other appearances are visible because each of the particle suspensions has different colors or different opacities or different refractive indices or 30 different reflection characteristics.

In other embodiments, the alcohol-based fragrance portion of the perfume formulation has a color or opacity and the suspension or suspension of particles has another color or opacity. 35

When the perfume formulation is sprayed on the skin, the particle suspension disintegrates and the particles are separated from the rest of the perfume formulation. Colored and opaque particles disperse on the user's skin and have a colorless appearance. However, glitter is seen on the user's skin. Surprisingly, the perfume embodiments disclosed in this document present to the consumer striking appearances and colors when they are in a container, but do not confer these colors and appearance on the skin, hair and clothing of consumers when the perfume is applied , unless the particles include a material such as glitter.

In one embodiment, the perfume formulation has a black appearance and color when it can be seen in a perfume bottle. However, the perfume is colorless when applied to the skin of a consumer. In this embodiment, the suspension of particles, such as black oxide particle, impart a black color to the perfume formulation when the formulation is stored in the bottle. Once the suspension is altered by spraying it through the dispenser, the perfume formulation is shown colorless on the consumer's skin. In embodiments where the perfume includes a suspension of particles that confer color and brightness, the spray perfume does not confer color when it is sprayed, but it does confer gloss.

Perfume formulation embodiments in which the sensory experience is olfactory

An olfactory experience occurs when the perfume formulation is dispensed from a container, such as a bottle. Normally, the formulation embodiments of perfume disclosed herein are dispensed with a spray nozzle and generate a fine mist. Conventional perfume spray nozzles can be used to dispense the perfume formulation embodiments disclosed herein.

An olfactory experience is caused by a fragrance that is stabilized within the alcohol-based fragrance formulation. The essence dispensed by this fragrance is dispersed in a fine mist. Additionally, in some embodiments of perfume formulation that include particles, the suspended, stable particles, include encapsulated or microsphere or both that retain additional essence that is the same as the alcohol-based essence of the perfume formulation. Encapsulation 25 includes in situ encapsulation and entrapment systems, such as those that include cellulose or encapsulated beads containing perfume when added to the perfume formulation. Encapsulation and entrapment systems include those that allow the fixation of fragrance oil, absorption / adsorption, on a solid particle. These fragrance oil absorption / adsorption systems include 30 particles such as porous PMMS, silica, zeolite, crosslinked allyl methacrylate polymer, etc.

In some embodiments, one or more additional essences that complement the non-particulate essence of alcoholic base are employed. In some embodiments, the particles include coatings or capsules that dissolve on the skin in

different moments, giving rise to a liberation in essence time and a prolonged effectiveness of the perfume formulation. This feature prolongs the fragrance sensation much longer than what is produced when the liquid is sprayed alone. In other embodiments, the suspension particles include essences that complement the fragrance in the alcohol and water solution. These particles release their essence (s) simultaneously with the spraying of the perfume formulation on the skin or in a time-release mode. In some embodiments, the particles release two or more essences in an orchestrated manner over time to provide the user with an unexpected dynamic olfactory sensation.

Therefore, the use of a suspension of particles containing essence suspended in an aqueous solution that also includes essence creates novel perfume formulations that have complex and interesting orchestrated olfactory releases. For example, consumers can perceive high marks immediately after the application, multiple and gradual intermediate notes that are felt over time and 15 multiple and gradual basic notes that follow the intermediate notes.

The perfume embodiments described herein allow the creation of new and so far impossible fragrance combinations, for example, floral, oriental, woody, leathers, Cyprus, Fougère, bright green floral, aquatic, citrus, 20 gastronomic fruit trees, and others in which the perfume formulation is presented to the user with an aesthetic and pleasant appearance and in a container.

The combination of the alcohol-based fragrance and the essence-containing particles can also be used to combine aromatherapy essences in an orchestrated system, as disclosed. The aromatherapy system disclosed in this document can be used to create an ever-changing and long-lasting experience that allows the consumer to relax or avoid food cravings, to mention two examples.

Perfume formulation embodiments in which the sensory experience is tactile

A tactile experience occurs when a user touches the perfume formulation when it is in a container. The perfume formulation embodiments disclosed herein are milder than the perfume embodiments that do not include

a stabilizing agent, without being tacky to the touch.

The tactile sensation also occurs when the perfume formulation is dispensed from the container on the skin of a consumer. In some embodiments, the perfume formulation includes conditioning particles within the stable suspension 5 that confer a softness or elasticity to the skin to which the fragrance is applied. These conditioning particles include one or more components to hydrate, prevent wrinkles and stimulate the growth of new cells. Moisturizers include aloe vera, altea, avocado oil, lemon balm, burdock, shea butter, camphor, chamomile, isodecyl oleate and other conditioning agents. 10

Perfume formulation embodiments in which the perfume formulation confers other characteristics

One type of embodiment in which the perfume formulation has other characteristics is one in which a type of encapsulation confers a particular appearance to a perfume and when applied to the skin and adds emollients or moisturizers or other materials beneficial to the skin, when the encapsulation is broken. In these embodiments, the particles within the suspension include one or more chelating agents, skin conditioners, emollients, preservatives, buffering agents, antioxidants, chelating agents, opacifying agents, acetic acid bleaching; acetyl hexapeptide to control wrinkles, horse chestnut seed extract to promote circulation; amino guanidine to prevent damage to collagen; Arctium majus extract to treat acne, psoriasis, eczema, ascorbic acid, beta-carotene, bisabolol, bromelain, ceramides, Cucumis sativa to firm the skin, jojoba oil, 25 tocopherol, vitamin A and similar kinds of optional ingredients known to those skilled in the art.

The particles disclosed herein constitute a dispersion which, in some embodiments, constitutes a network in combination with the suspending agent and the alcohol-water fragrance solution. In some embodiments, the particle suspension and the suspending agent form a sun, which has a predetermined viscosity that is suitable for an application. The perfume is applied to the skin of a consumer by atomizing the fragrance with a spray nozzle. The particles are stabilized by the stabilizing agent of the suspension. 35

In one or more embodiments, the particles are treated with a coating that makes the particles more dispersible in a water and alcohol fragrance formulation. In other embodiments, the particles are not coated. In some embodiments, the suspending agent and particles create the viscosity of a fragrance product.

In some embodiments, the particles include encapsulation systems.

The scented formulation embodiments disclosed herein may remain stable in a container such as a bottle for a long period of time when exposed to a wide temperature range and over a wide pH range. In some embodiments of the invention, the perfume formulation also includes a transparent container to house the formulation and a dispenser to dispense the formulation.
