Description

Background Art

[0001] In the perfume industry, there has long been a need for aqueous, ethanol-free perfume oil compositions. While ethanolic solutions of perfume oils are widely used, such compositions suffer from various drawbacks that are sometimes unacceptable to consumers. Opposition to the use of ethanol in perfume oil compositions is based on, for example, the risk of skin irritation caused by ethanol, religious reasons, or the carcinogenicity of ethanol, as well as legal regulations regarding the avoidance of volatile organic compounds (VOCs). This contrasts with the acceptability of aqueous formulations, which are non-flammable and generally considered harmless by consumers. Accordingly, the perfume industry has attempted to develop suitable ethanol-free perfume oil compositions in the past. However, to date, it has been unable to provide an ethanol-free perfume oil composition that is (unconditionally) accepted by consumers.

[0002] Ethanol-free perfume oil compositions known in the prior art typically contain, in addition to one or more perfume oils, water and optionally one or more preservatives, as well as one or more surfactants for dissolving the one or more perfume oils. However, surfactants can cause skin irritation and often result in a perfume composition that feels tacky to consumers.

[0003] US 2003 / 0186836 A1 describes alcohol-free aqueous perfume oil compositions which contain isopentyl glycol (3-methyl-1,3-butanediol) as solvent (instead of ethanol).

[0004] WO 2005 / 123028 A1 describes ethanol-free, perfumed aqueous microemulsions which contain vicinal diols as solvents. According to WO 2005 / 123028 A1, surfactants can only be optionally included in the microemulsion.

[0005] US 8,343,521 B2 discloses an ethanol-free microemulsion composition consisting of: a fragrance material, wherein the fragrance material is present in an amount greater than 5 wt % and less than 50 wt %; a solvent, wherein the solvent is 1,2-hexanediol or 1,2-heptanediol; and an aqueous medium, wherein the composition does not contain a surfactant.

[0006] US Pat. No. 8,513,180 B2 describes ethanol-free perfume oil microemulsions composed of water, at least one vicinal diol, and one or two solvents for reducing greasiness, wherein the solvent comprises 1-hydroxy-2,2,4-trimethyl-3-pentyl isobutyrate or 3-hydroxy-2,2,4-trimethyl-1-pentyl isobutyrate.

[0007] There remains interest in providing ethanol-free fragrance compositions that are transparent and can be used in various applications in the perfume industry. The present invention addresses this need in the art. Summary of the Invention

[0015] A novel combination of cosmetically approved ingredients has been identified that provides a non-sticky, fast-drying, alcohol-free fragrance base with no film residue. The fragrance base is transparent, allowing for the design of a variety of fragrance compositions using non-restrictive fragrance ingredient guidelines. Advantageously, the fragrance base can be dosed with between 3 wt.% and 30 wt.%, such as between 3 wt.% and 25 wt.%, between 5 wt.% and 30 wt.%, or between 5 wt.% and 25 wt.%, or between 5 wt.% and 20 wt.% of fragrance ingredients and is particularly useful in preparing sprayable, alcohol-free compositions such as eau de toilette.

[0016] More particularly, the present invention relates to a transparent alcohol-free matrix and its use in preparing a fragrance composition, wherein the matrix consists of:

[0017] (i) at least one solubilizing agent selected from the group consisting of polysorbate 20, sodium olivate, glyceryl polyether cocoate, and polyethylene glycol (16) macadamia glyceride;

[0018] (ii) at least two emollients, said emollients comprising isopentyl glycol and 3-methoxy-3-methyl-1-butanol; and

[0019] (iii) at least two solvents, the solvents comprising water and pentanediol.

[0020] The matrix of the present invention is transparent because it transmits light without significant scattering, allowing objects located outside it to be clearly seen. Alternatively, the fragrance matrix of the present invention is transparent and therefore not turbid or opaque. Likewise, the fragrance composition comprising the fragrance matrix is ​​transparent.

[0021] As indicated, the base is "alcohol-free" and, in the context of the present invention, is preferably essentially free of alcohol, in particular free of ethanol, or comprises at least less than 0.01 wt.% of alcohol, preferably less than 0.001 wt.% of alcohol relative to the total weight of the base or fragrance composition of the present invention.

[0022] In certain aspects, the matrix is ​​formulated as a microemulsion.In the context of the present invention, the term "microemulsion" refers to a macroscopically homogeneous, optically transparent and thermodynamically stable mixture.

[0023] The matrix of the present invention comprises at least one solubilizing agent. "Solubilizing agent" refers to an agent that increases the solubility of another substance. In some aspects, the solubilizing agent is polysorbate 20 (CAS No. 9005-64-5), sodium olivetate (CAS No. 61789-88-6), glyceryl polyether cocoate (CAS No. 68201-46-7), polyethylene glycol (16) macadamia glyceride (CAS No. 220459-99-4), or a combination thereof. In some aspects, the solubilizing agent is polysorbate 20.

[0024] The base of the present invention further comprises at least two emollients. "Emollient" refers to a substance that helps soothe, soften, and increase moisture content, particularly in the skin. In certain aspects, the at least two emollients of the fragrance base of the present invention are isopentyldiol (also known as isoprene glycol; CAS No. 2568-33-4) and 3-methoxy-3-methyl-1-butanol (CAS No. 56539-66-3).

[0025] The base of the present invention also comprises at least two solvents. "Solvent" refers to a substance that dissolves a solute, thereby producing a solution. In certain aspects, the solvents of the fragrance base of the present invention are water, butanediol (CAS No. 6290-03-5), and pentanediol (1,2-pentanediol; CAS No. 5343-92-0).

[0026] For purposes of the present invention, the fragrance base does not contain one or more of glycerin, hexylene glycol, 1-hydroxy-2,2,4-trimethyl-3-pentyl isobutyrate, or 3-hydroxy-2,2,4-trimethyl-1-pentyl isobutyrate).

[0027] In some aspects, the transparent alcohol-free matrix comprises, consists of, or consists essentially of: a solubilizing agent component at between about 15 wt.% and 25 wt.% relative to the total weight of the matrix; isoprene glycol at between 5 wt.% and 10 wt.% relative to the total weight of the matrix; 3-methoxy-3-methyl-1-butanol at between 3 wt.% and 8 wt.% relative to the total weight of the matrix; water at between 35 wt.% and 45 wt.% relative to the total weight of the matrix; and pentanediol at between 20 wt.% and 30 wt.% relative to the total weight of the matrix. In some aspects, the matrix further comprises dipropylene glycol (DPG) at between about 1 wt.% and 10 wt.%.

[0028] In other aspects, the transparent alcohol-free matrix is ​​composed of: polysorbate 20, sodium olivate, glyceryl polyether cocoate, polyethylene glycol (16) macadamia glycerides, or a combination thereof, between about 15 wt.% and 25 wt.% relative to the total weight of the matrix; isoprene glycol, between 5 wt.% and 10 wt.% relative to the total weight of the matrix; 3-methoxy-3-methyl-1-butanol, between 35 wt.% and 45 wt.% relative to the total weight of the matrix; and pentylene glycol, between 20 wt.% and 30 wt.% relative to the total weight of the matrix. In some aspects, the matrix further comprises dipropylene glycol (DPG), between about 1 wt.% and 10 wt.%.

[0029] In another aspect, the present invention provides a fragrance composition comprising a fragrance base in combination with one or more fragrance ingredients. As used herein, the terms "fragrance composition," "fragrance formulation," "perfume composition," "fragrance accord," or "perfume accord" are compositions composed of one or more fragrance ingredients to impart a pleasant scent or cover a malodor.

[0030] In some aspects, the present invention provides a fragrance composition, which is composed of at least one fragrance, at least one solubilizing agent, at least two emollients and at least two solvents. In certain aspects, the present invention provides a fragrance composition, which comprises, consists of or consists essentially of: at least one fragrance; at least one solubilizing agent selected from the group consisting of polysorbate 20, sodium olivetate, glyceryl polyether cocoate and polyethylene glycol (16) macadamia glyceride; at least two emollients selected from the group consisting of isopentyl glycol and 3-methoxy-3-methyl-1-butanol; and at least two solvents selected from the group consisting of water and pentylene glycol.

[0031] As used herein, the terms "perfume," "fragrance," "fragrance material," and "fragrance ingredient" are used interchangeably to refer to a component in a fragrance composition that is capable of imparting or modifying the odor of a substrate (e.g., skin). "Fragrance ingredient" can encompass any suitable fragrance raw material for fragrance use, including materials such as alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpenes, nitrogen- or sulfur-containing heterocyclic compounds, and essential oils. Non-limiting examples of fragrance materials can also include pro-fragrances, such as acetal pro-fragrances, ketal pro-fragrances, ester pro-fragrances, hydrolyzable inorganic-organic pro-fragrances, and mixtures thereof. Fragrance materials can be released from pro-fragrances in a variety of ways. For example, fragrances can be released due to simple hydrolysis, or by displacement of an equilibrium reaction, or by pH changes, or by enzymatic release. LogP and water solubility determine the stability of the whole fragrance in the matrix. High-dose ingredients with lower logP values ​​and high water solubility produce the best results in the matrix described herein. Individual fragrance ingredients are readily available from commercial sources such as International Flavor & Fragrances (New York, NY), Givaudan Fragrances Corp. (East Hanover, NJ), Symrise (Branchburg, NJ), and Firmenich (Princeton, NJ).

[0032] The fragrance composition can comprise at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more fragrance ingredients. In some aspects, the fragrance composition comprises at least 10, at least 15, at least 20, at least 25, at least 30, at least 35, at least 40, at least 45, and / or at least 50 additional fragrance ingredients. The more fragrance raw materials that make up a fragrance composition, the more complex the fragrance composition is considered to be.

[0073] Example 1: Base formulation with added fragrance

[0074] An alcohol-free base of the present invention was formulated with dipropylene glycol (DPG) and 11% fragrance (Table 1).

[0075] Table 1

[0076] Element Function Wt% purified water Thinner / Solvent 38 DPG Thinner / Solvent 3 Isopentyldiol Emollients 8 MMB Emollients 5 Polysorbate 20 solubilizer 15 Pentylene glycol Solubilizer / preservative 20 spices spices 11

[0077] MMB, 3-methoxy-3-methyl-1-butanol.

[0078] Example 2: Sensory performance of a base formulation without alcohol

[0079] The fragrances of Table 1 in an alcohol-free base (11 wt%) (Samples 1 and 2) were compared to similar fragrances in a hydroalcoholic base (16 wt%) (Comparative: 80 wt% Specially Denatured Ethanol 40B and 4 wt% Water). The fragrances of Samples 1 and 2 are similar to each other, with Sample 1 being the original fragrance and Sample 2 having less high logP musk.

[0080] The fragrance formulation was applied to the substrate and allowed to dry for 4 hours. A trained panel of subjects (N=12) performed a blinded and randomized sensory analysis of the fresh and dried samples. The panel evaluated the intensity, i.e., the impact and substantivity, of the fragrance at 0 and 4 hours after application using an 11-point scale. In addition, the panel evaluated the ability of the fragrance in each sample to maintain its characteristic properties. The analysis was based on a 7-point scale (very different --> the same), with paired comparisons (percentage of lasting intensity after 4 hours: calculated slope between T0h and T4h).

[0081] This analysis showed that when comparing the two fragrances in a non-alcoholic base to similar fragrances in a hydroalcoholic base, while there were no statistically significant differences in impact or fixation, the non-alcoholic base exhibited statistically better longevity (Table 2).

[0082] Table 2

[0083]

[0084] Samples not connected by the same letter are significantly different. Significance level = 10%.

[0085] Example 3: Environmentally friendly alcohol-free matrix formulation

[0086] In addition to the above examples, a number of "green" or environmentally friendly formulations that would achieve an alcohol-free matrix were tested (Table 3).

[0087] Table 3

[0088]

[0089] MMB (3-methoxy-3-methyl-1-butanol)

[0090] DPG (dipropylene glycol)

[0091] Specifically, the solubilizers sodium olivate and glyceryl cocoate can replace polysorbate 20, and the diluent / solvent butylene glycol can replace DPG.

[0092] The environmentally friendly formulations of Table 3 passed the stability test, maintaining clarity, olfactory intensity, and characteristic properties. Test conditions included freeze-thaw cycles, as well as accelerated testing at 5°C, 25°C, and 45°C (data not shown).

[0093] Of particular interest is that high levels of fragrance (>15%) can be used and the formulation retains its properties.

[0094] The ranges of recited values ​​disclosed in this specification include values ​​that one of ordinary skill in the art would consider equivalent to the recited value (eg, having the same function or result), for example, + / - 5%-10% of the recited value.

[0095] The claims are not limited to the preferred embodiments and examples, but are intended to cover numerous modifications and equivalents consistent with the entire written description.
