Description

Title of the invention: Long-lasting mixture, perfumed composition comprising the mixture, and perfumed alcoholic solution. Technical field

[0001] The present invention relates to a fragrance longevity optimization mixture, a perfumed composition comprising the mixture, and a perfumed alcoholic solution comprising said composition. The invention finds particular application in the fields of perfumery, cosmetics, detergents, and home fragrance to improve longevity on any surface, such as skin, hair, or textiles. STATE OF THE ART

[0002] Improving the potency and longevity of perfumes is a constant challenge in the perfume industry. Consumers expect a product that delivers not only functional performance over time, but also emotional performance through fragrance.

[0003] Perfumes are commonly formulated in compositions containing alcohol as a solvent or diluent. Alcohol has the advantage and disadvantage of carrying aromatic molecules with it when it evaporates. The aromatic molecules are thus quickly absorbed by the user. However, the strength of the perfume diminishes rapidly and the fragrance does not last long.

[0004] Conversely, mixtures known in the state of the art for providing lasting power to perfumes, such as polycitronellol or sucrose acetate isobutyrate, tend to sequester the top notes, meaning that the intensity of the perfume is diminished a few seconds after application. Furthermore, existing solutions can cause changes in the olfactory profile of the perfume.

[0005] Moreover, at present, regulations relating to chemical compounds are constantly evolving and users are increasingly looking for natural products that comply with COSMOS type standards.

[0006] The present invention aims to provide a solution that optimizes the longevity of perfumes and meets these new requirements.

[0007] 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. SUMMARY

[0008] To achieve this objective, according to one embodiment, a residual mixture is provided comprising 30% of disopropyl sebacate, and 70% of triheptanoin, the percentages being by weight of the total weight of the mixture.

[0009] The selection of the compounds of the mixture according to the invention made it possible to obtain a very good residual fragrance efficiency of a perfumed composition or of a perfumed alcoholic solution in which it can be integrated.

[0010] According to another aspect, the invention relates to a perfumed composition comprising the residual mixture.

[0011] According to another aspect, the invention relates to a perfumed alcoholic solution comprising alcohol as a diluent and 3% to 30% perfume composition, by weight of the total weight of the perfumed alcoholic solution. BRIEF DESCRIPTION OF FIGURES

[0069] According to one aspect, the invention relates to an alcoholic solution comprising from 3 to 30% of the composition and at least one diluent, preferably, the alcoholic solution comprises 15% of the perfumed composition.

[0070] By way of example, the alcoholic solution comprises 10% of the composition by weight of the total weight of the solution, i.e. 0.3% of diisopropyl sebacate and 0.7% of triheptanoin, the percentages being by weight of the total weight of the composition.

[0071] Preferably, the diluent, or at least one diluent, is an alcohol. The alcohol used as a diluent is chosen to suit the final application; by way of preferred example, the alcohol is chosen from ethanol, isopropanol, methoxymethylbutanol, and other diluents such as glycol ethers, for example, dipropylene glycol methyl ether. Alternatively, the diluent, or at least one diluent, may be a mixture of alcohol and water.

[0090] The present invention will be described in more detail with the help of the following examples, which are purely illustrative.

[0095] Example 3: Triangular tests of sensory analysis

[0096] The compositions of Examples 1 and 2 are used at 15% in hydroalcoholic solution compared to 15% hydroalcoholic solutions of the control compositions in which the residual mixture is replaced by DPG (Dipropylene glycol) to compare the olfactory performance at t=0 (in a triangular test) and the potency over time (in a skin persistence test at t=2h, 4h, and 8h). The alcoholic solution comprises 15% of the perfumed composition, 6% water, and 79% ethanol; more precisely, the alcoholic solution in this example is a hydroalcoholic solution.

[0097] Method

[0098] The 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 of differentiation thresholds found in ISO 4120:2021.

[0099] In our case, we have 21 participants. The differentiation threshold is therefore 12 correct answers for a confidence level of 0.95.

[0100] Results

[0101] At t=0, no significant difference was identified between the solutions without the residual mixture and with the residual mixture, nor in the alcoholic solution. including the citrus perfume composition nor on the alcoholic solution including the floral perfume composition.

[0102] The formulated residual mixture therefore does not cause any change in the olfactory profile of the compositions in alcoholic solution at t=0. [Fig.1].

[0103] We therefore do not observe a sequestering effect of the top notes.

[0104] Example 4: Skin persistence test on alcoholic solutions of compositions with and without mixture

[0105] Method

[0106] The compositions of Examples 1 and 2, as well as the control compositions in which the residual mixture is replaced by DPG (Dipropylene glycol), are used at 15% in alcoholic solution and then applied to the arms of a volunteer. One arm is treated with the alcoholic solution comprising 15% of the perfumed composition containing 10% of the residual mixture, and the other arm with the alcoholic solution comprising 15% of the control perfumed composition containing 10% DPG. The alcoholic solution is composed identically to Example 3.

[0107] The panel assesses the intensity of the fragrance by comparing the two arms, then completes a questionnaire in sequential monadic format. The strengths are rated on a linear scale from 1 (Very weak) to 10 (very strong).

[0108] The panel evaluates the different intensities on scales generated by the FIZZ Biosystemes software. The responses are then automatically recorded by this software at the end of the questionnaire.

[0109] The data are processed and analyzed using statistical tests and FIZZ Treatments specifically adapted for sensory analysis. Standard processing will be performed, namely an analysis of variance (or ANOVA), which is the statistical model used to compare sample means.

[0110] Results

[0111] For the alcoholic solution containing the floral fragrance composition, we therefore observed +30% intensity thanks to the residual mixture at 2h, +22% at 4h and +29% at 8h compared to the alcoholic solution containing the composition without the residual mixture. Figures 2 to 4.

[0112] For the alcoholic solution containing the citrus fragrance composition, we obtained +12% intensity thanks to the residual mixture at 2h, +21% at 4h and +17% at 8h compared to the alcoholic solution containing the composition without the residual mixture. Figures 5 to 7.

[0113] Some perfumers have found that by 2 a.m. the heart notes were already expressing themselves for the alcoholic solution containing the unblended composition, while the alcoholic solution containing the blended composition was still in the top notes. The addition The mixture therefore prolongs the duration of each olfactory experience in the perfume's olfactory pyramid.
