Description

FRAGRANCE FIXATIVESFIELD OF INVENTION

[0001] The present invention relates in general to the fields of personal care products, cosmetics and fragrances and to compositions of matter used in consumer products.

[0002] More specifically, the invention relates to the use of a perfume fixative and to a method of fixing fragrance in perfume compositions and personal care products containing such perfume compositions.BACKGROUND OF THE INVENTION

[0003] Perfume compositions consist in general of a number of fragrance components having different volatility. During storage and application more volatile fragrances evaporate faster, altering the quality of the composition. To maintain the fragrant quality of such compositions over a longer period of time, measures have to be taken to prevent early evaporation of the more volatile components.

[0004] Generally, so called "fixateurs" or "perfume fixatives" are added to the compositions. The perfume fixatives form loose complexes with the more volatile components of the perfume composition, thus reducing volatility of the fragrances contained therein. The perfume fixatives may either be odorless or have an odor which contributes to the scent of the fragrance composition. For the perfumer it is easier to use odorless perfume fixatives, as these do not impart an additional odor and therefore allow a dosage over a wide range without altering much the fragrance quality. Further odorless perfume fixatives can be used in a wide range of different perfume compositions.

[0005] In view of all the above, there remains a continuous and further need for improved perfume fixatives that are cost efficient, environmentally friendly, and odorless, while maintaining fragrance longevity of perfume compositions, in particular said perfume compositions having a maintained prolonged fragrance release over an extended period of time.

[0006] Thus, the underlying objective of the present invention was to provide a compound or a mixture of compounds, which can be used to reduce volatility of the fragrances within aperfume composition, which is moreover environmentally friendly, preferably odorless or having less odor, and can be easily manufactured.SUMMARY OF THE INVENTION

[0007] This is solved by the use of isopropyl myristate (IPM) or cetearyl ethylhexanoate (CEH) or a mixture of IPM and CEH in a perfume composition as a perfume fixative and / or enhancer. The use of the mixture of IPM and CEH as a perfume fixative and / or enhancer is a preferred embodiment.

[0008] The inventors have surprisingly found that the compound CEH or the compound IPM or preferably a mixture comprising or consisting of isopropyl myristate and cetearyl ethylhexanoate has the ability to enhance the perceived intensity of a perfume composition and / or maintain the fragrance release of a perfume composition over an extended period of time. In other words, the mixture according to the invention is able to enhance or improve the fragrance profile, preferably the intensity or character, of the fragrances within the perfume composition.

[0009] Additionally, the inventors have discovered that the perfume fixative and / or enhancer according to the invention can extend the fragrance character, preferably the portion of the fragrance profile attributable to the volatile fragrances within the perfume composition. By "extend" it is meant that the fragrance profile of the perfume composition, preferably the components contributed by the volatile fragrance materials, can be perceived by the consumer at later time points such as for example, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours, and possibly all the way up to 24 hours after application as compared to controls, i.e., compositions containing no substantially non-odorous fragrance fixatives.

[0010] The inventors have also discovered that the perfume fixative and / or enhancer according to the invention is able to enhance a perfume composition. In other words, already existing note of the perfume composition are perceived by the user in a stronger way than the notes in a control perfume composition without the mixture according to the invention.

[0011] As used herein, articles such as "a" and "an" when used in a claim, are understood to mean one or more of what is claimed or described.

[0012] As used herein, the terms "include", "includes" and "including" are meant to be nonlimiting.

[0013] As used herein, "perfume composition" shall mean any composition that contains one or more fragrance. Perfume compositions release fragrance(s) upon delivery to a desired location under desired conditions, in amounts sufficient to produce a desired aroma. In some embodiments, perfume compositions contain several fragrances or fragrance compounds or several combinations of fragrances having different release profiles after application. In some embodiments, the perfume compositions contain different "notes," typically referred to as: "top note," denoting the aroma that is most noticeable immediately after delivery or application of a perfume composition and caused or influenced by the fragrances that are most volatile or otherwise release the most quickly from the composition; "middle note," an intermediate aroma that bridges from top note to the base or bottom note and due to fragrances having an intermediate release profile; and the "base note" or "bottom note," which are those materials which have an aroma that is detectable the longest after application. In some embodiments, a formulation containing top, middle and base notes is prepared to give a desired balance between these three groups.

[0014] A perfume composition may contain any desired combination of fragrances and resulting notes, formulated to achieve desired fragrance character. The perfume composition can, for example, include ingredients providing various notes of the fragrance families (for example, green notes, fruity notes, aldehydic notes, chypre notes, oriental notes, tobacco notes, leather notes and fougere notes), and sub-classifications thereof (such as fresh and balsamic green notes; fresh and sweet floral notes; floral and flora I -woody-powdery aldehydic notes; and fresh-mossy-aldehydic, floral-mossy-animalic and mossy-fruity chypre notes). Any acceptable fragrances or combinations thereof can be utilized.

[0015] As used herein, the terms „fixative", „fixateur", and „erfume fixative and / or enhancer" are used interchangeably to designate an agent having the capacity to affect the fragrance profile, such as for example, by impacting the fragrance materials' evaporation rate. The fixative may mediate its effect by lowering the vapor pressure of the fragrances within a perfume composition and increasing their adherence to the substrate (skin and / or hair) thus ensuring a longer-lasting impression of the perfume composition.

[0016] As used herein, the term "substantially non-odorous" means an agent that does not impart an odour of its own when added into a composition of the present invention. For example, a "substantially non-odorous perfume fixative" does not impart a new odour that alters the character of the fragrance profile of the perfume composition to which it is added. The term "substantially non- odorous" also encompasses an agent that may impart a minimalor slight odour of its own when added into a composition of the present invention. However, the odour imparted by the "substantially non-odorous perfume fixative" is generally undetectable or tends to not substantively alter the character of the fragrance profile of the composition to which it is added initially or preferably over time.

[0017] As used herein, the term "vapor pressure" means the partial pressure in air at a defined temperature (e.g., 25 °C) and standard atmospheric pressure (e.g., 760 mmHg or 101.325 kPa) for a given chemical species. It defines a chemical species' desire to be in the gas phase rather than the liquid or solid state. The higher the vapor pressure the greater the proportion of the material that will, at equilibrium, be found in a closed headspace. It is also related to the rate of evaporation of a fragrance material which is defined in an open environment where material is leaving the system. The vapor pressure is determined according to the reference program Advanced Chemistry Development (ACD / Labs) Software Version 14.02, or preferably the latest version update.

[0018] The components of the perfume fixative and / or enhancer and the mixtures comprising or consisting of isopropyl myristate (IPM) and cetearyl ethylhexanoate (CEH), for example PCL-Liquid 100 (pure CEH) or PCL-Liquid (CEH 90 / IPM 10) are known to be a unique emollient providing outstanding skin suppleness. They show high spreading capacity and good skin wetting properties which makes the skin soft, smooth and supple and shows water repellent properties. It also produces a thin hydrophobic film on the skin which protects from drying out while it maintains natural water vapor permeability of the skin and counteracts occlusion. PCL-Liquid 100 or PCL-Liquid has high resistance to oxidation. Therefore it it very surprising that these components or preferably their mixture are also suitable for the use as a perfume fixative and / or enhancer.

[0019] In a preferred embodiment according to the invention, the perfume composition comprises the perfume fixative and / or enhancer from 2 to 30% by weight, calculated on the total amount of the perfume composition. More preferably, the perfume composition comprises the perfume fixative and / or enhancer from 1 to 15% by weight, calculated on the total amount of the perfume composition. Most preferably the perfume fixative and / or enhancer is the mixture of CEH and IPM.

[0020] Preferably, the weight ratio of isopropyl myristate and cetearyl ethylhexanoate is in the range of about 85:15 to 15:85, preferably 80:20 to about 20:80, more preferably in therange of about 70:30 to about 30:70. In another very preferred embodiment of the invention the weight ratio of IPM to CEH is between 85:15 to 55:45.

[0021] In a preferred embodiment according to the invention the perfume composition comprises at least one fragrance. Preferably, the perfume composition comprises at least two, at least three, at least four, at least five, at least six, at least seven, at least eight, at least nine, at least ten fragrances. As stated above, the perfume composition may contain any desired combination of fragrances and resulting notes, formulated to achieve the desired fragrance character.

[0022] Preferably, the weight ration of all fragrances in the perfume composition to the perfume fixative and / or enhancer is in the range of about 1 :99 to 99:1, more preferably in the range ob about 10:90 to 90:10, more preferably in the range ob about 20:80 to 80:20, more preferably in the range ob about 30:70 to 70:30, more preferably in the range ob about 40:60 to 60:40.

[0023] In a preferred embodiment of the invention the perfume fixative and / or enhancer, preferably the mixture comprising or consisting of isopropyl myristate and cetearyl ethylhexanoate, is substantially free of odour, more preferably completely free of odour.

[0046] In the following, the invention is further characterized on the basis of the examples.EXAMPLESExample 1Evaluation of fragrances

[0047] 166 fragrance raw materials have been evaluated with 4% PCL Liquid 100 (pure CEH).

[0048] The tested fragrance raw materials have been evaluated as follows: The fragrances raw materials have been mixed with 4% PCL-Liquid 100 (pure CEH) and sprayed on glass slides. An expert panel consisting of 10 trained individuals has performed the evaluation. Top, heart and base notes have been evaluated; the top notes after 30 minutes, the heart notes after 3 hours and the base notes after 6 hours. The evaluation ratings take into account the intensity and the odor profile of the scent compared to the fresh sample in alcohol without the fixative. The expert panel has used the following scale for its evaluation of longlasting freshness, which is not an intensity scale but a qualitative evaluation that shows if the olfactive strength and faithful character pf a fresh sample can be kept in a conventional alcoholic application:Table 1 : Evaluation criteriaThe results can be seen in the following table:Table 2: Results of Expert evaluationSY 1047 woExample 2

[0049] Tests of olfactory profile with the ingredient Citral (1% solution in ethanol as a solvent plus fixative mixture) Three samples were tested. One was a pure alcoholic sample, one contained pure IPM and one contained a fixative combination of 4% CEH and 18% IPM based on the weight of the mixture.The intensity of the mixture with the inventive ingredients was perceived by an expert panel as higher after 30 min (=5.4) compared to a pure alcoholic micture (=3.7). Also the IPM sample (=4.9) was higher than the alcoholic control, but not as good as the mixture of CEH and IPM.The sample with the combination was also ranked by 93% of the panel as being most true to the original composition in terms of olfactory profile.

[0050] The same test was performed after 3h and while the absolute intensity was perceived lower in values than after 30 minutes, the relative difference again showed that the composition with the fixative mixture was the best with a value of (3.8) compared to the alcoholic sample (1.7). Again the pure IPM sample (3.1) performed better than the ethanolSY 1047 wo sample, but not as good as the mixture of fixatives. Also here 93 % of the panelists found the composition with the inventive fixative mixture as most true to the original olfactory profile.Example 3

[0051] Tests of olfactory profile of a fragrance mixture (10% solution in ethanol as a solvent plus fixative or fixative mixture)

[0052] Again three samples were tested. The pure fragrance mixture in ethanol, the fragrance mixture in ethanol plus pure IPM and the fragrance mixture in ethanol with 4% CEH and 9% IPM based on the weight of the composition The frangrance composition contained the following ingredients:SY 1047 wo

[0053] The panelist ranked the intensity of the 3 samples after 3h. The sample with the fixative combination of CEH ands IPM according to the invention was ranked best (average 2.2) with alcoholic sample second best (average 2.0) and the pure IPM the least intense (average 1.8).
