Clear alcohol-free base for fragrance compositions

Abstract

A clear, alcohol-free base for fragrances is provided. Also provided are fragrance compositions and consumer products that include the clear, alcohol-free base.

Description

[Technical Field]

[0001] The perfume industry has long sought aqueous, ethanol-free perfume oil compositions. While ethanol-containing solutions of perfume oils are certainly widely used, such compositions have various drawbacks and may not be accepted by consumers. Objections to the use of ethanol in perfume oil compositions are based, for example, on the risk of skin irritation caused by ethanol, religious reasons, or legal restrictions regarding the carcinogenic potential of ethanol and the avoidance of volatile organic substances (VOCs). This contrasts with the acceptance of aqueous formulations, which are non-flammable and generally considered harmless by consumers. Therefore, in the past, the perfume industry has already attempted to develop suitable ethanol-free perfume oil compositions. However, to date, it has not been possible to provide ethanol-free perfume oil compositions that are (unconditionally) accepted by consumers. [Background technology]

[0002] Ethanol-free perfume oil compositions known in the prior art generally contain, together with perfume oil, water and, optionally, preservatives and one or more surfactants used to solubilize the perfume oil. However, in consumer opinion, surfactants can cause skin irritation and generally make perfume compositions feel sticky.

[0003] US Patent Application Publication No. 2003 / 0186836A1 describes an alcohol-free aqueous perfume oil composition that contains isoprene glycol (3-methyl-1,3-butanediol) as the solvent (instead of ethanol).

[0004] WO 2005 / 123028 A1 describes ethanol-free, perfumed aqueous microemulsions containing vicinal diols as solvents. According to WO 2005 / 123028 A1, surfactants are only optionally contained in the microemulsions.

[0005] US Patent No. 8,343,521 B2 discloses an ethanol-free microemulsion composition comprising a fragrance material present in an amount greater than 5% and less than 50% by weight, a solvent which is 1,2-hexanediol or 1,2-heptanediol, and an aqueous medium, the composition being surfactant-free.

[0006] US Patent No. 8,513,180 B2 describes an ethanol-free perfume oil microemulsion composed of water, at least one vicinal diol, and one or two solvents to reduce stickiness, the solvents including isobutyric acid-1-hydroxy-2,2,4-trimethyl-3-pentyl ester or isobutyric acid-3-hydroxy-2,2,4-trimethyl-1-pentyl ester.

[0011] As used herein, "comprises," "including," "includes," "including," "has," "having," or any other variation thereof, is intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that includes a list of components is not necessarily limited to only those components and may include other components not expressly listed or inherent in such process, method, article, or apparatus. Furthermore, unless expressly stated otherwise, "or" means an inclusive or, not an exclusive or. For example, condition A or condition B is satisfied by any one of the following: A is true (or exists) and B is false (or does not exist), A is false (or does not exist) and B is true (or exists), and A and B are both true (or exist).

[0012] Additionally, the use of "a" or "an" is used to describe components and ingredients described herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be interpreted to include one or at least one, and the singular also includes the plural unless it is clear that it has a different meaning.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In case of conflict, the present specification, including definitions, will control. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present invention, suitable methods and materials are described below. Furthermore, the materials, methods, and examples are illustrative only and not intended to be limiting.

[0014] The present disclosure illustratively described herein may suitably be practiced in the absence of any element or elements, limitation or limitations not specifically disclosed herein. Although compositions and methods are described herein in terms of "comprising" various components or steps, unless otherwise specified, the compositions and methods can also "consist essentially of" or "consist of" the various components or steps.

[0015] A novel combination of cosmetically approved ingredients has been identified that provides a non-sticky, fast-drying, alcohol-free fragrance base that does not leave a film. The fragrance base is transparent, allowing for the design of various fragrance compositions using non-limiting fragrance ingredient guidelines. Advantageously, the fragrance base can be loaded with 3 to 30% by weight of fragrance ingredients, e.g., 3 to 25% by weight, 5 to 30% by weight, or 5 to 25% by weight, or 5% to 20% by weight, which is particularly useful for preparing sprayable, alcohol-free compositions such as eau de toilette.

[0016] More specifically, the present invention relates to a clear alcohol-free base and its use for preparing a fragrance composition, the base comprising: (i) at least one solubilizer selected from the group consisting of polysorbate 20, sodium olivate, cocoate glycerides, and polyethylene glycol (16) macadamia glycerides; (ii) at least two emollients comprising isopentyldiol and 3-methoxy-3-methyl-1-butanol; (iii) at least two solvents including water and pentylene glycol; It consists of:

[0017] The base of the present invention is transparent in that it transmits light without significant scattering, allowing objects behind it to be clearly seen. In other words, the perfume base of the present invention is transparent and therefore not cloudy or opaque. Similarly, perfume compositions containing the perfume base are transparent.

[0018] As indicated, the base is "alcohol-free" and in the context of the present invention preferably contains substantially no alcohol (in particular no ethanol) or contains at least less than 0.01% by weight, preferably less than 0.001% by weight, of alcohol relative to the total weight of the base or perfume composition of the present invention.

[0019] In certain embodiments, the substrate is formulated as a microemulsion. The term "microemulsion" in the context of the present invention denotes a macroscopically homogeneous, optically clear, and thermodynamically stable mixture.

[0020] The base of the present invention includes at least one solubilizer. "Solubilizer" refers to an agent that increases the solubility of another substance. In some embodiments, the solubilizer is polysorbate 20 (CAS No. 9005-64-5), sodium olivate (CAS No. 61789-88-6), glyceryl cocoate (CAS No. 68201-46-7), polyethylene glycol (16) macadamia glycerides (CAS No. 220459-99-4), or a combination thereof. In some embodiments, the solubilizer is polysorbate 20.

[0021] The base of the present invention further comprises at least two emollients. "Emollient" refers specifically to a substance that helps soothe, soften, and increase the moisture level of the skin. In a specific embodiment, the at least two emollients in the fragrance base are isopentyldiol (also known as isoprene glycol, CAS No. 2568-33-4) and 3-methoxy-3-methyl-1-butanol (CAS No. 56539-66-3).

[0022] The base of the present invention also includes at least two solvents. A "solvent" refers to a substance that dissolves a solute to form a solution. In certain embodiments, the solvents in the fragrance base are water, butylene glycol (CAS No. 6290-03-5), and pentylene glycol (1,2-pentanediol, CAS No. 5343-92-0).

[0023] For purposes of the present invention, a perfume base does not include one or more of glycerol, hexylene glycol, isobutyric acid-1-hydroxy-2,2,4-trimethyl-3-pentyl ester or isobutyric acid-3-hydroxy-2,2,4-trimethyl-1-pentyl ester).

[0024] In some embodiments, the clear, alcohol-free base comprises, consists of, or consists essentially of about 15% to 25% by weight of a solubilizing component based on the total weight of the base, 5% to 10% by weight of isopentyldiol based on the total weight of the base, 3% to 8% by weight of 3-methoxy-3-methyl-1-butanol based on the total weight of the base, 35% to 45% by weight of water based on the total weight of the base, and 20% to 30% by weight of pentylene glycol based on the total weight of the base. In some embodiments, the base further comprises about 1% to 10% by weight of dipropylene glycol (DPG).

[0025] In another embodiment, the clear, alcohol-free base is composed of about 15% to 25% by weight of polysorbate 20, sodium olivate, cocoyl glycerol, polyethylene glycol (16) macadamia glycerides, or a combination thereof, 5% to 10% by weight of isopentyl diol, 3% to 8% by weight of 3-methoxy-3-methyl-1-butanol, 35% to 45% by weight of water, and 20% to 30% by weight of pentylene glycol, based on the total weight of the base. In some embodiments, the base further comprises about 1% to 10% by weight of dipropylene glycol (DPG).

[0026] In a further aspect, the present invention provides a fragrance composition comprised of 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 comprised of one or more fragrance ingredients to impart a pleasant odor or to mask a malodor.

[0027] In some embodiments, the present invention provides a fragrance composition comprising at least one fragrance, at least one solubilizer, at least two emollients, and at least two solvents. In certain embodiments, the present invention provides a fragrance composition comprising, consisting essentially of, or consisting of at least one fragrance, at least one solubilizer selected from the group consisting of polysorbate 20, sodium olivate, glycereth cocoate, and polyethylene glycol (16) macadamia glycerides, at least two emollients selected from the group consisting of isopentyldiol and 3-methoxy-3-methyl-1-butanol, and at least two solvents selected from the group consisting of water and pentylene glycol.

[0028] As used herein, the terms "perfume," "fragrance," "fragrance material," and "fragrance ingredient" are used interchangeably to designate ingredients in a fragrance composition that can impart or modify the odor of a substrate, such as skin. "Fragrance ingredient" may include any suitable perfume raw material for perfumery, including materials such as alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpene hydrocarbons, nitrogen or sulfite heterocyclic compounds, and essential oils. Non-limiting examples of fragrance materials may also include pro-fragrances, such as acetal pro-fragrances, ketal pro-fragrances, ester pro-fragrances, hydrolyzable inorganic-organic pro-fragrances, and mixtures thereof. The fragrance material can be released from the pro-fragrance in many ways. For example, the fragrance can be released as a result of simple hydrolysis or by a shift in equilibrium reaction, or a pH change, or by enzymatic release. LogP and water solubility determine the stability of a full fragrance in a base. High dosages of ingredients with low logP values ​​and high water solubility provide the best results in the bases 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).

[0029] A perfume composition may comprise at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more perfume ingredients. In some embodiments, the perfume 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 perfume ingredients. The greater the number of perfume raw materials comprising a perfume composition, the more complex the perfume composition will be.

[0038] Unless otherwise indicated, all parts, percentages and ratios referred to in this specification and claims are by weight.

[0039] The values ​​and dimensions disclosed herein should not be understood to be strictly limited to the exact numerical values ​​recited. Instead, unless otherwise specified, each such value is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a value disclosed as "50%" is intended to mean "about 50%," including, for example, 50±5%.

[0040] When an amount, concentration, or other value or parameter is given as a range, a preferred range, or a list of upper and / or lower preferred values, this is understood to specifically disclose any range formed by any pairing of any upper or preferred value of the range with any lower or preferred value of the range, regardless of whether the ranges are separately disclosed. When a range of numerical values ​​is recited herein, unless otherwise specified, the range is intended to include the endpoints, and all integers and fractions within the range. For example, if a range of "1 to 10" is recited, this recited range should be interpreted to encompass ranges such as "1 to 8," "3 to 10," "2 to 7," "1.5 to 6," "3.4 to 7.8," "1 to 2 and 7 to 10," "2 to 4 and 6 to 9," "1 to 3.6 and 7.2 to 8.9," "1 to 5 and 10," "2 and 8 to 10," "1.5 to 4 and 8," etc.

[0042] Without further elaboration, it is believed that one skilled in the art can, based on the description herein, utilize the present invention to its fullest extent. All publications cited herein are hereby incorporated by reference in their entirety. [Example]

[0043] Example 1: Flavored Base Formulation The alcohol-free base of the present invention was blended with dipropylene glycol (DPG) and 11% fragrance (Table 1). [Table 1]

[0044] Example 2: Sensory performance of alcohol-free base formulations The fragrance (11 wt%) in the alcohol-free bases (Samples 1 and 2) in Table 1 was compared to the similar fragrance (16 wt%) in a hydroalcoholic base (comparison example: 80 wt% Special Denatured Alcohol 40B and 4 wt% water). The fragrances in Samples 1 and 2 are similar to each other, with Sample 1 being the original fragrance and Sample 2 having less of the high log P musk.

[0045] The fragrance formulations were applied to the substrate and allowed to dry for 4 hours. A panel of trained subjects (N=12) performed a blinded, randomized sensory analysis of the fresh, dried samples. The panel rated the intensity, i.e., perfume potency and persistence, on an 11-point scale at 0 and 4 hours after application. In addition, the panel evaluated the ability of the fragrance in each sample to maintain its properties. The analysis was based on a 7-point scale (very different -> identical) with pairwise comparisons (percentage of persistence intensity after 4 hours: slope calculated between T0h and T4h).

[0046] This analysis showed that there was no statistically significant difference in potency or longevity when comparing the two fragrances in an alcohol-free base with the similar fragrances in a hydroalcoholic base, but the alcohol-free base showed statistically better longevity (Table 2). [Table 2]

[0047] Example 3: Environmentally friendly alcohol-free base formulation In addition to the examples above, several "green" or environmentally friendly formulations were tested that allow for an alcohol-free base (Table 3). [Table 3]

[0048] Specifically, the solubilizers sodium olivate and glyceryl cocoate can replace polysorbate 20, and the diluent / solvent butylene glycol can replace DPG.

[0049] The eco-friendly formulations in Table 3 passed stability testing, retaining clarity and olfactory strength and characteristics. Test conditions included freeze-thaw cycles and accelerated testing at 5°C, 25°C, and 45°C (data not shown).

[0050] The ability to use high levels of fragrance (>15%) with formulations that retain their properties is particularly interesting.

[0051] The recited numerical ranges disclosed herein include values ​​that one of ordinary skill in the art would consider equivalent to the recited value, e.g., having the same function or result, e.g., ±5 to 10% of the recited value.

[0052] The claims are not limited to the preferred embodiments and examples, but encompass many modifications and equivalents consistent with the description given as a whole.
