Description

[0001] "A mixture comprising beta ionone, alpha ionone, cedrol, hexanal, and C10 aldehyde, and its use in masking unpleasant odors."

[0002] TECHNICAL FIELD

[0003] The present invention relates to a mixture of compounds and its use to mask bad odors.

[0004] The present invention will find its application in the field of masking bad odors, whether they be body odors, environmental odors or odors from an enclosed space.

[0005] STATE OF THE ART

[0006] In humans, the olfactory system consists of a set of receptors. An odor is perceptible once it reaches a certain olfactory perception threshold. This threshold corresponds to a concentration of odorant molecules per liter of air. It is also referred to as the threshold of discernment, reached when an individual is able to differentiate, discriminate, judge, and appreciate an odor. Thus, in a sample, the concentration of odorant molecules plays a significant role in odor perception.

[0007] During olfaction, odor molecules travel up the nasal cavity to reach the olfactory epithelium, where olfactory nerve cells are located. These odor molecules are captured by the olfactory nerve cells, triggering a cascade of reactions that ultimately generate a nerve impulse. In the central nervous system, the olfactory bulb receives these nerve impulses and transmits them to the olfactory cortex, where they are identified and associated with olfactory values.

[0008] Olfactory perception allows us to characterize odors by their intensity, quality, and perceived value. The intensity of an odor is defined by the quantity of odorant molecules. The quality of odors is linked to the identity of the odorant molecule. The perceived value of an odor refers to the pleasant or unpleasant nature of an olfactory sensation.

[0009] Fragrance mixtures, both natural and synthetic, can be used in cosmetics, perfumery, and household or air freshener products. These mixtures provide a pleasant olfactory experience for the user. However, in some applications, this pleasant olfactory component can be disrupted by other unpleasant olfactory components, such as the active ingredients of the product containing the fragrance mixture, or by an external factor (tobacco odor, body odor, etc.).

[0010] The so-called pleasant olfactory component must therefore be intense enough to compensate for the so-called unpleasant olfactory component. Finding the balance between pleasant and unpleasant olfactory components is thus a major problem in the perfume industry.

[0011] Furthermore, for any subsequent use, the fragrance mixtures must be stable, meaning they must not degrade over time and must not react with other components of the product in which they are contained.

[0012] In perfumery, obtaining a versatile fragrance blend that is stable, pleasant and able to mask bad odors is the subject of ongoing research.

[0013] Regulations concerning chemical compounds are constantly evolving, and users are increasingly seeking natural products that comply with COSMOS-type standards. The present invention aims to provide an odor-masking solution that meets these various requirements.

[0014] The other objects, features, and advantages of the present invention will become apparent from an examination of the following description and accompanying drawings. It is understood that other advantages may be incorporated.

[0015] SUMMARY

[0016] To achieve this objective, according to one aspect, the invention relates to a mixture, advantageously intended to mask bad odors, comprising 35% beta ionone, 30% alpha ionone, 30% cedrol, 4% hexanal, 1% C10 aldehyde, the percentages being by weight of the total weight of the mixture.

[0017] The selection of the compounds in the mixture according to the invention has made it possible to obtain very good masking efficiency without olfactory impact on the composition in which it can be integrated.

[0018] The olfactory profile of the composition that can receive the mixture according to the invention is not or only slightly modified.

[0019] The object of the present invention is to obtain an odorous mixture with improved intensity and longevity, capable of masking bad odors, said mixture being able to be integrated into any type of perfume, i.e. into any olfactory family.

[0020] In another aspect, the invention relates to a perfumed composition comprising from 0.1% to 5% of the mixture as described above by weight of the total weight of the perfumed composition. BRIEF DESCRIPTION OF FIGURES

[0028] DETAILED DESCRIPTION

[0029] Before proceeding with a detailed review of embodiments of the invention, the following are optional features that may be used in combination or alternatively:

[0030] According to one example, the mixture masking bad odors consists of 35% beta ionone, 30% alpha ionone, 30% cedrol, 4% hexanal, 1% C10 aldehyde, the percentages being by weight of the total weight of the mixture.

[0031] According to one example, the perfumed composition comprises 0.1% to 1% of the masking mixture by weight of the total weight of the composition;

[0032] According to one example, the perfume composition includes a maximum of 10 allergenic substances, preferably listed in Commission Regulation (EU) 2023 / 1545 of 26 July 2023 amending Regulation (EC) No 1223 / 2009 of the European Parliament and of the Council, included in Table 1.

[0033] According to one example, the invention relates to a cosmetic base comprising the perfumed mixture or composition.

[0034] According to one example, the invention relates to a detergent base comprising the perfumed mixture or composition.

[0035] According to one example, the invention relates to an ambient fragrance comprising the perfumed mixture or composition.

[0036] In one example, the invention relates to the use of the fragrance mixture or composition, or the cosmetic base, detergent base, or air freshener to mask unpleasant odors. In another example, the invention relates to a method of using the fragrance mixture or composition, or the cosmetic base, detergent base, or air freshener, comprising applying the fragrance mixture or composition, or the cosmetic base, detergent base, or air freshener to mask unpleasant odors.

[0037] Advantageously, the perfumed mixture or composition, or cosmetic base, detergent base, or room fragrance is applied, or sprayed, or added to a support or into the air.

[0038] A parameter "approximately equal to / greater than / less than" or "of the order of" a given value means that this parameter is equal to / greater than / less than the given value, to within 10% or even 5% of that value.

[0039] For the purposes of this disclosure, "A and / or B" means (A), (B), or (A and B). For the purposes of this disclosure, "A, B, and / or C" means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B, and C).

[0040] According to the invention, "mixture", "masking mixture" or "odorant mixture" means a mixture comprising beta ionone, alpha ionone, cedrol, hexanal and C10 aldehyde. For the purposes of the present invention, "mixture", "masking mixture" and "odorant mixture" shall be used interchangeably.

[0041] Thus, by "composition" we mean a composition comprising the mixture according to the invention. Typically, this composition is a perfumed composition.

[0042] The term "perfume composition" refers to a composition comprising a mixture of perfume substances, said perfume substances being in an isolated state, in solution or in suspension, in their usual diluents, solvents or co-ingredients. Such a composition is intended to provide a pleasant olfactory component.

[0043] By "pleasant smell" we mean a smell that is detected by the human sense of smell and is perceived as pleasant.

[0044] By "bad odors," we mean odors that are detected by the human sense of smell and are perceived as offensive or unpleasant. For the purposes of this invention, the bad odors to be masked may result intrinsically from the cosmetic, detergent, or air freshener base itself, or they may originate from the external environment.

[0045] By "masking bad odors," we mean modifying the qualitative perception of the odor by adding a substance or mixture of substances capable of providing a new, distinct, and pleasant odor.

[0046] The present invention relates to a mixture comprising beta ionone, alpha ionone, cedrol, hexanal and C10 aldehyde.

[0047] Beta ionone is a compound with CAS No.: 14901-07-6, EINECS No.: 238-969-9 and IUPAC name: 4-(2,6,6-trimethylcyclohexen-1-yl)but-3-en-2-one.

[0048] Alpha ionone is a compound with CAS No. 127-41-3, EINECS No. 204-841-6, and IUPAC name 4-(2,6,6-trimethylcyclohex-2-ene-1-yl)-but-3-ene-2-one. Cedrol is a compound with CAS No. 77-53-2, EINECS No. 201-035-6, and IUPAC name [3R-(3a,3aB,6a,7B,8aa)]-octahydro-3,6,8,8-tetramet.

[0049] Hexanal is a compound with CAS No. 66-25-1, EINECS No. 200-624-5, and IUPAC name: hexanal. The C10 aldehyde is a compound with CAS No. 112-31-2, EINECS No. 203-957-4, and IUPAC name: decanal.

[0050] Advantageously, it has been identified that the mixture comprising 35% beta ionone, 30% alpha ionone, 30% cedrol, 4% hexanal and 1% C10 aldehyde, the percentages being by weight of the total weight of the mixture, exhibits very good masking efficiency of bad odors while respecting the olfactory profile of a composition in which it is integrated.

[0051] Preferably, the mixture consists of 35% beta ionone, 30% alpha ionone, 30% cedrol, 4% hexanal and 1% C10 aldehyde, the percentages being by weight of the total weight of the mixture.

[0052] According to a preferred option, the mixture is used in a composition.

[0053] The invention relates to an advantageously perfumed composition comprising the mixture as described above.

[0054] The composition comprises from 0.1% to 5% of the mixture by weight of the total weight of the composition. Preferably, the composition comprises from 0.5% to 1% of the mixture by weight of the total weight of the composition.

[0055] As an example, the composition comprises 0.5% of the mixture by weight of the total weight of the composition, i.e. 0.175% of beta ionone, 0.150% of alpha ionone, 0.150% of cedrol, 0.02% of hexanal and 0.005% of C10 aldehyde, the percentages being by weight of the total weight of the composition.

[0056] The composition is advantageously a perfumed composition, that is to say a composition comprising one or a mixture of perfumed substances also generically referred to as perfume.

[0057] Advantageously, the mixture and composition are stable.

[0058] By "stable" we mean a composition that does not degrade over time and whose components do not react with each other. "Stable" also means that the homogeneity, color, olfactory intensity, olfactory quality, and / or viscosity of the composition are maintained. More specifically, the composition according to the present invention is stable under accelerated aging after 24 hours under UV light (Suntest) and after 2 months at 25°C and 45°C compared to a sample kept at 5°C, protected from light.

[0203] Cigarette butts and ashes are collected to create a bad tobacco smell.

[0204] Example 8: Analysis of the effectiveness of a composition comprising the mixture according to the invention against bad odors.

[0205] Perfume compositions No. 1 to 3 and control perfume compositions of examples 1 to 3 are tested in sensory analysis to prove their masking effectiveness against the bad odors of examples 4 to 7.

[0206] The methods used are based on international standards, applicable in the field of industries, which employ olfactory analysis, as is the case within the company Expressions Parfumées:

[0207] - ISO 5492 (Sensory analysis - vocabulary),

[0208] - ISO 6658:2005 (Sensory analysis - Methodology - General guidelines,

[0209] - NF V 09-006 (Sensory analysis - Methodology - Introduction and training in the detection and recognition of odors),

[0210] - ASTM E1958-12 (Standard Guide for Sensory claim substantiation), - ASTM E1593-13 (Standard Guide for Assessing the efficacy of Air Care products in reducing the perception in indoor malodor).

[0211] These sensory analyses make it possible to define masking properties, to draw up a sensory profile and to discriminate between perfumed compositions.

[0212] Test preparation:

[0213] Each test presents the Bad Odor alone as a control, then the Bad Odor mixture with the perfumed composition for comparison.

[0214] The Bad Odor is introduced into an odorless glass jar with a capacity of 3 L on a 4 cm piece of cellulose 2(80p I for bad cooking odors, 10 pl for bad toilet odors, 10 pl for bad perspiration odor) or in a jar (2g of cigarette butts and ashes). The scented compositions are tested as a concentrate at a level of 0.15 g on a 4 cm piece of cellulose. 2 which is placed next to the one for Bad Odor in a 3L jar.

[0215] The jars are coded, randomized, and anonymized according to ASTM E1958-12 to ensure a blinded test and thus minimize bias. Diffusion time in the jars before evaluation: 30 minutes.

[0216] - Assessment :

[0217] The evaluation is carried out by the Internal Expert Panel (Perfumers, Evaluators and Analysts), which comprises on average 30 people.

[0218] The panel evaluates the fragrance composition and then completes a sequential monadic questionnaire: the intensity of the unpleasant odor and the intensity of the fragrance in each jar are compared to the control jar containing only the unpleasant odor and to the other available fragrance compositions alone. The strengths are rated on a linear scale from 1 (Very weak) to 10 (Very strong).

[0219] - Statistical analysis of the data:

[0220] The statistical processing of the data is carried out with an analysis of variance (95% confidence interval) using the FIZZ by BIOSYSTEMES software.

[0221] Results :

[0222] The results of the different compositions are given in Figure 1 for bad sweat odor.

[0223] Fragrance compositions No. 1 through 3 containing the masking blend are more effective at masking body odor than fragrances without the masking blend. The masking blend adds 6% more effectiveness against body odor for the Aloe fragrance composition, 7% more effectiveness for the Healthy Tea fragrance composition, and 18% more effectiveness for the Apricot fragrance composition.

[0224] The 3 perfumed compositions with the masking blend thus allow a reduction in the perception of bad odors and, as illustrated for the bad odor of perspiration, of 46 to 49% compared to the control.

[0225] Example 9: Fragrance composition No. 4 containing 0.5% masking mixture or ethyl citrate to form the control. The masking mixture and the other components of the fragrance composition described in Table 8 are mixed to obtain fragrance composition No. 4.

[0226] [Table 8]

[0227] Example 10: Perfume composition No. 5 containing 0.5% masking mixture or ethyl citrate to form the control.

[0228] The masking mixture and the other components of the fragrance composition described in Table 9 are mixed to obtain fragrance composition No. 5.

[0229] [Table 9]

[0230] Example 11: Perfume composition No. 6 containing 0.5% masking mixture or ethyl citrate to form the control.

[0231] The masking mixture and the other components of the fragrance composition described in Table 10 are mixed to obtain fragrance composition No. 6.

[0232] [Table 10]

[0233] Example 12: Testing the effectiveness of the mixture masking bad odors.

[0234] Objective and experimental approach to testing against bad odors.

[0235] The test protocol was developed following the methods of ISO 6658:2017 & ASTM E1593 - 13 standards to demonstrate the reduction in the perception of bad odors from cooking, toilets and perspiration.

[0236] The evaluations of the tested references are carried out by the internal panel made up of olfactory experts and trained panelists in individual booths.

[0237] All the tested references are prepared in accordance with the principles of sensory analysis: anonymous, coded and randomized, in order to minimize bias.

[0238] All the data obtained are statistically analyzed. This data provides quantifiable information on the tested perfumes, with the aim of addressing our research question.

[0239] We use a formula that reproduces a bad odor, in particular the bad odor of perspiration, and which is presented alone as a control and then in the presence of the masking mixture.

[0240] A scale from 0 (very weak) to 10 (very strong) is used to assess the olfactory intensity of the residual bad odor.

[0241] Result of the test against bad odors for the perfumed composition including the masking blend.

[0242] The perfumed composition comprising the masking blend of the invention, corresponding in this example to perfumed composition No. 6, demonstrated a significant reduction in the perception of all unpleasant odors. This reduction in the perception of unpleasant odors was always at least 50%, and particularly at least 53.5% for the unpleasant odor of perspiration.

[0243] Example 13: Triangular tests. The objective is to verify that there is no significant difference between fragrance compositions containing the masking agent and fragrance compositions without the masking agent (replaced by a solvent). To do this, we performed triangular tests:

[0244] Perfume composition No. 4 with masking blend versus Perfume composition No. 4 without masking blend.

[0245] Fragrance composition No. 5 with masking blend versus fragrance composition No. 5 without masking blend.

[0246] Perfume composition No. 6 with masking blend versus Perfume composition No. 6 without masking blend.

[0247] The evaluation of the perfume compositions was carried out by our trained panel in individual booths.

[0248] All the tested references are prepared in accordance with the principles of sensory analysis: anonymous, coded and randomized, in order to minimize bias.

[0249] All the data obtained are statistically analyzed. This data provides quantifiable information on the tested perfumes, with the aim of addressing our research question.

[0250] The Triangular Test: Panelists are given two identical samples and one different sample. They are asked to identify the different product. If enough panelists give the correct answer, the products are considered different. If enough panelists give the incorrect answer, the products are considered identical. The differentiation threshold is set according to the number of panelists for a confidence level of 0.95 and according to the table defined by the triangular testing methodology of ISO 4120:2021.

[0251] In our case, according to this standard, we have 39 and 36 participants depending on the test. The differentiation threshold is therefore 16 correct answers with a confidence level of 0.95.

[0252] Results of the triangular tests are illustrated in figures 2 to 4.

[0253] Regarding fragrance composition No. 4, Figure 2, 10 judges perceived an olfactory difference between the two tested versions, one with and one without the masking mixture, which is below the differentiation threshold. It can be concluded that fragrance compositions No. 4 with and without the masking mixture are perceived as olfactorily identical.

[0254] Regarding fragrance composition No. 5, Figure 3, 15 judges perceived an olfactory difference between the two tested versions, one with and one without the masking mixture, which is below the differentiation threshold. It can be concluded that fragrance compositions No. 5 with and without the masking mixture are perceived as olfactorily identical.

[0255] Regarding fragrance composition No. 6, Figure 4, 9 judges perceived an olfactory difference between the two tested versions, with and without the masking mixture, which is below the differentiation threshold. It can be concluded that fragrance compositions No. 6 with and without the masking mixture are perceived as olfactorily identical.

[0256] Example 14: Efficacy test of fragrance compositions with the odor-masking blend. The test protocol was developed following the methods of ISO 6658:2017 & ASTM E1593-13 standards to demonstrate the reduction in the perception of unpleasant odors from cooking, toilets, and perspiration.

[0257] The evaluations of the tested references are carried out by the internal panel made up of 5 olfactory experts and trained panelists in individual booths.

[0258] All the tested references are prepared in accordance with the principles of sensory analysis: anonymous, coded and randomized, in order to minimize bias.

[0259] All the data obtained is statistically processed. This data provides quantifiable information on the tested perfumes, with the aim of addressing our 10th problem.

[0260] We use a formula that replicates an unpleasant odor, specifically the odor of perspiration, and which is presented first alone as a control and then alongside fragrance compositions that include or do not include the masking agent. The three fragrance compositions tested are those described above, with and without the masking agent.

[0261] 15. A scale from 0 (very weak) to 10 (very strong) is used to assess the olfactory intensity of the residual bad odor. A scale from 0 (very weak) to 10 (very strong) is used to assess the intensity of the fragrance composition.

[0262] Results of tests on the effectiveness of perfumed compositions against bad odors.

[0263] All fragrance compositions containing the masking blend showed a 20% reduction in the perception of unpleasant odors compared to fragrance compositions without the masking blend. This reduction in perception is generally at least 40%, particularly 45% for the unpleasant odor of perspiration with fragrance composition No. 4, Figure 5.

[0264] The results demonstrate the effectiveness of scented compositions containing the masking blend 25 on the perception of bad odors.

[0265] Results of the intensity of perfume compositions in the presence of bad odors.

[0266] Regarding the evaluation of the intensity of the perfumes, it was judged to be significantly better on all perfume compositions that contain the masking mixture compared to perfume compositions that do not contain the masking mixture.

[0267] 30 The results demonstrate the intensity of the perfumed composition No. 4 containing the masking mixture even in the presence of bad odors, figure 6.

[0268] Example 15:

[0269] Comparative tests were carried out for different mixtures.

[0270] The masking mixture corresponding to the invention is compared to 7 other compositions on the effect

[0271] 35 on masking the bad smell of perspiration carried out according to example 6.

[0272] It is observed that the reduction of bad perspiration odor is effective only for the masking mixture according to the invention and that none of the 7 other mixtures allows to reach this level of masking demonstrating a surprising synergy of the components of masking mixture 5.
