Description

Title of the invention: Perfumed aqueous composition comprising at least two surfactants, at least one perfuming substance and at least one diol Technical field

[0001] The present invention aims to propose a new perfumed cosmetic composition, for the field of perfuming keratin materials and / or clothing, but also for the care or cosmetic treatment of keratin materials. Prior art

[0002] Generally speaking, the formulation of environmentally friendly cosmetic products is becoming an important issue in order to satisfy new consumer expectations, in particular those of natural and / or eco-designed products, i.e. products whose design and development take environmental impacts into account.

[0003] It is thus common to seek to replace synthetic compounds present in cosmetic compositions with natural and / or naturally derived ingredients.

[0004] These environmental issues concern all cosmetic products, particularly perfumed compositions.

[0005] It is known that a perfume is the combination of different odorous substances which evaporate at different times. Each perfume has what is called a "top note" which is the odor diffused first when the perfume is applied or when the container containing it is opened, a "heart or body note" which corresponds to the complete perfume (emission for a few hours after the "top note") and a "base note" which is the most persistent odor (emission for several hours after the "heart note"). The persistence of the base note corresponds to the remanence of the perfume.

[0006] Human beings have always sought to perfume themselves and the objects around them or the places in which they find themselves, both to mask strong and / or unpleasant odors and to give a good smell.

[0007] It is common to incorporate perfume into a number of products or compositions, in particular cosmetic and dermatological products such as fresh waters, toilet waters, perfume waters, aftershave lotions, treatment waters or even colognes.

[0008] A perfume or a perfume composition must be stable and have a pleasant smell. They must resist different aggressions such as light and dif- temperature differences.

[0009] Furthermore, transparency or translucency is a particularly sought-after and appreciated effect which corresponds to a current trend, also applicable to perfume compositions.

[0010] Thus, consumers are looking for completely transparent perfume compositions.

[0011] The difficulty to be resolved in order to meet this need is to produce a composition with a high concentration of perfume or aroma, and this without affecting the transparency of the composition, the incorporation of a perfume in a fairly large quantity generally resulting in an opaque product.

[0012] Furthermore, a problem specific to the field of perfume compositions is that of the typical presence of alcohol.

[0013] Indeed, in the preparation of perfume compositions such as perfumes or eaux de toilette, the use of ethanol as a solvent is very widespread. Ethanol allows the perfume ingredients used by the perfumer to be well solubilized. It is a very good solvent which evaporates quickly, thus providing a sensation of freshness. Ethanol also has the advantage of being inexpensive and allowing the formulation of transparent compositions.

[0014] For such reasons, the majority of perfume compositions on the market contain ethanol, generally present in high levels.

[0015] However, there is currently a trend on the international market towards ethanol-free perfumes, with a consumer preference for ethanol-free products aimed at sensitive skin and allowing safe use.

[0016] Indeed, the presence of ethanol makes perfume compositions irritating to the skin and tends to dry it out.

[0017] Furthermore, ethanol has a significant volatility, and it is thus desirable to obtain perfuming compositions whose ethanol content is very low, or even zero. Description of the invention

[0018] There therefore remains a need for new transparent perfumed formulations, in particular aqueous ones, without ethanol, containing essentially natural products and / or of natural origin, and which remain stable and homogeneous over time and under the effects of light and temperature.

[0019] In particular, there remains a need to have such perfumed cosmetic compositions, the evolution of the organoleptic properties of which, namely the odor and / or the color, is controlled over time.

[0020] There also remains a need to increase the persistence of such perfuming compositions on keratin materials without the perfume degrading, in particular in contact with the other constituents of the composition. In addition, it is interesting to provide consumers with perfume formulas that foam very little, or even do not foam at all, despite the use of surfactant, and which are visually pleasing.

[0021] There also remains a need for such compositions which provide softness and hydration when applied to keratin materials, particularly the skin.

[0022] Finally, there also remains a need to have perfume compositions compatible with current consumer requirements, particularly from an environmental point of view.

[0023] The present invention aims precisely to meet these needs. Summary of the invention

[0024] Thus, according to a first of its aspects, the present invention relates to an aqueous perfumed composition, in particular a cosmetic composition, comprising: - a) at least one non-ionic surfactant chosen from C6-C10 alkyl polyglucosides; - b) at least one additional surfactant, distinct from the non-ionic surfactant a), preferably chosen from non-ionic and / or anionic surfactants; - c) at least one perfume substance; and - d) at least one diol; it being understood that: the weight ratio of surfactant(s) a) / perfuming substance(s) c) is between 0.1 and 2; and the composition comprises an ethanol content of less than or equal to 2% by weight, relative to the total weight of the composition.

[0025] Preferably, in a composition according to the invention, the weight ratio of surfactant(s) a) / perfuming substance(s) c) is between 0.2 and 1.5, and preferably between 0.3 and 1.

[0026] Preferably, the ethanol content in the composition is less than or equal to 1% by weight, more particularly less than or equal to 0.5% by weight, relative to the total weight of the composition, preferably the composition is free of ethanol.

[0027] The inventors have found, surprisingly, that the combination of at least one specific non-ionic surfactant with perfuming substances in a particular ratio, and with at least one diol, makes it possible to obtain a homogeneous and stable transparent perfumed cosmetic composition, even in the presence of a high content of perfuming substances, which do not degrade over time.

[0028] The presence of an additional surfactant distinct from the specific surfactant mentioned above makes it possible to formulate such perfuming compositions whose properties organoleptic properties are further improved, in particular the color deteriorates less over time, the fragrance left after application is more intense and the foaming character is reduced.

[0029] The perfumed composition according to the invention also provides hydration and a feeling of softness, and does not require the presence of ethanol.

[0030] Preferably, a composition according to the invention comprises at least 90% by weight of natural or naturally occurring compounds, in particular at least 95% by weight, preferably at least 98% by weight, and more preferably at least 99% by weight, relative to the total weight of the composition.

[0031] Preferably, a composition according to the invention is transparent.

[0032] A composition according to the invention is intended in particular for the cosmetic treatment of keratin materials.

[0033] Thus, the invention relates, according to yet another of these aspects, to a method for the cosmetic treatment of keratin materials, in particular of the skin, comprising at least one step of applying to said keratin materials a composition according to the invention.

[0034] The invention also relates to a method for the cosmetic treatment of keratin materials, in particular the skin, or of a garment, comprising at least one step of applying to said keratin materials and / or said garment, a perfumed composition according to the invention.

[0035] It is understood that the cosmetic treatment methods referred to in the present application are non-therapeutic.

[0036] A composition according to the invention is intended in particular to be used in order to perfume keratin materials and / or clothing.

[0037] Thus, the invention also relates, according to another of its aspects, to a method for perfuming keratin materials, and in particular the skin, and / or a garment, preferably the skin, comprising the application to said keratin materials and / or said garment of the composition as defined above.

[0038] Preferably, the application of the composition can be done by spraying, in particular using a sprayer. Definitions

[0039] In the context of the present invention, and unless otherwise indicated, the following definitions apply:

[0040] By "natural" in the sense of the present invention, is meant a compound or extract obtained directly from the earth or soil, or from plants or animals, via, where appropriate, one or more physical processes, such as for example grinding, refining, distillation, purification or filtration, or even resulting from a biotechnological process, in particular from cell cultures or microbio logical, for example from fungi or bacteria. So-called "natural" compounds include compounds that are present in nature and can be reproduced by chemical (hemi)synthesis.

[0041] For the purposes of the present invention, the term “of natural origin” is intended to denote any compound obtained from a natural substance having undergone one or more additional chemical or industrial treatments, resulting in modifications that do not affect the essential qualities of this substance. As a non-limiting example of additional chemical or industrial treatments resulting in modifications that do not affect the essential qualities of a natural compound, mention may be made of those authorized by control organizations such as Ecocert (Reference for organic and ecological cosmetic products, January 2003) or defined in recognized manuals in the field, such as “Cosmetics and Toiletries Magazine”, 2005, vol. 120, 9:10.

[0042] According to the invention, a compound is considered to be natural or of natural origin when it is predominantly composed of natural constituents, that is to say when the weight ratio of the natural constituents to the non-natural constituents which compose it is greater than 1.

[0043] By "perfumed composition" or "perfuming composition" or even "perfume" within the meaning of the present invention, is meant any composition leaving a perfume after application to keratin materials.

[0044] For the purposes of the present invention, the term “perfuming substance” is understood to mean any perfume, any odorous raw material or aroma capable of releasing a pleasant odor, in particular as defined in the remainder of the text. “Perfuming”, “odorous” or “odoriferous” substances are synonymous for the purposes of the present invention.

[0045] For the purposes of the present invention, the term “keratin materials” is understood to mean in particular the skin, the lips, the hair, the scalp, the eyelashes and eyebrows or even the nails, in particular the skin and / or the lips, and preferably the skin.

[0046] By "clear" or "transparent" in the sense of the present invention, it is meant that the composition is transparent, that is to say that it lets light pass through and the objects behind it appear clearly.

[0047] In particular, to evaluate the transparency of a composition according to the invention, a conventional commercial test tube is taken, made of transparent, untinted glass, borosilicate, soda-lime or neutral glass such as Pyrex® or Duran® glass material, 16 cm high and 1.6 cm in diameter, which is filled up to 14 cm of said tube (the bottom of the meniscus of the composition in the tube is 14 cm from the bottom of the tube), and a published international application page (in A4 format) is placed behind it at a distance of 1 cm; and by placing one's eyes at a distance (reading focal length relative to the test tube) of between 20 cm and 40 cm, such as 30 cm, and the perpendicular of the middle of the composition of said tube (approximately 7 cm from the bottom of said tube), we evaluate whether we can read distinctly through the composition in said tube, said page of the published international patent application, in particular the first page. It is understood that the tester sees correctly, or that he equips himself with glasses, lenses or any other optical devices that he normally uses to read. We can for example use the application WO 2018 / 104428 and evaluate the sharpness, i.e. manage to read the 31 lines of page 13 to carry out the test or better do the reading test on the first page.

[0048] A composition according to the invention is generally suitable for application to keratin materials, in particular topical application to the skin, and therefore generally comprises a physiologically acceptable medium, i.e. compatible with the skin.

[0049] It is preferably a cosmetically acceptable medium, that is to say which has a pleasant color, odor and feel and does not generate unacceptable discomfort, that is to say tingling, tightness, redness, likely to discourage the user from applying this composition.

[0050] By “(Cx-Cz)alkyl” group is meant a linear or branched hydrocarbon chain comprising from x to z carbon atoms. For example, a (Ci-C6)alkyl group represents a linear or branched hydrocarbon chain comprising from 1 to 6 carbon atoms.

[0051] The expression “at least one” is equivalent to “one or more”.

[0052] The expressions “between ... and ...”, “includes from ... to ...”, “formed from ... to ...”, and “ranging from ... to ...” must be understood inclusively, unless otherwise specified.

[0053] Other characteristics, variants and advantages of the compositions according to the invention will become more apparent on reading the description and examples which follow. Detailed description a) C6-C10 alkyl polyglucoside

[0107] As mentioned previously, a composition according to the invention comprises at least one perfuming substance.

[0108] Perfumes are compositions containing in particular the raw materials described in S. Arctander, Perfume and Flavor Chemicals (Montclair, NJ, 1969), in S. Arctander, Perfume and Flavor Materials of Natural Origin (Elizabeth, NJ, 1960) and in “Flavor and Fragrance Materials - 1991”, Allured Publishing Co. Wheaton, 111.

[0109] A perfumed composition according to the invention preferably comprises at least one perfuming substance chosen from essential oils, perfumes and aromas of synthetic or natural origin, and their mixtures.

[0110] These may be natural products, such as essential oils, absolutes, resinoids, resins, concretes, and / or synthetic products, such as terpene or sesquiterpene hydrocarbons, alcohols, phenols, aldehydes, ketones, ethers, acids, esters, nitriles, peroxides, saturated or unsaturated, aliphatic or cyclic.

[0111] According to the definition given in the international standard ISO 9235 and adopted by the European Pharmacopoeia Commission, an essential oil is an odorous product generally of complex composition, obtained from a botanically defined plant raw material, either by steam distillation, or by dry distillation, or by an appropriate mechanical process without heating (cold expression). The essential oil is most often separated from the aqueous phase by a physical process which does not cause a significant change in the composition.

[0112] The choice of method for obtaining essential oils depends mainly on the raw material: its original state and its characteristics, its nature itself. The “essential oil / plant raw material” yield can be extremely variable depending on the plants: 15 ppm to more than 20%. This choice determines the characteristics of the essential oil, in particular viscosity, color, solubility, volatility, enrichment or depletion in certain constituents.

[0113] Steam distillation corresponds to the vaporization in the presence of water vapor of a substance that is poorly miscible with water. The raw material is placed in the presence of boiling water or water vapor in a still. The water vapor entrains the essential oil vapor which is condensed in the condenser to be recovered in liquid phase in a Florentine vase (or essencier) where the essential oil is separated from the water by decantation. The aqueous distillate that remains after steam distillation, once the separation of the essential oil has been carried out, is called "aromatic water" or "hydrosol" or "floral distilled water".

[0114] Obtaining by dry distillation consists of obtaining the essential oil by distillation of wood, bark or roots, without adding water or water vapor in a closed enclosure designed so that the liquid is recovered in its lower part. Cade oil constitutes the best known example of this method of obtaining.

[0115] The method of obtaining by cold expression only applies to citrus fruits (Citrus spp) by mechanical processes at room temperature. The principle of the method is as follows: the zests are shredded and the contents of the secretory pockets which have been broken are recovered by a physical process. The classic process consists of exerting an abrasive action under a stream of water on the entire surface of the fruit. After elimination of solid waste, the essential oil is separated from the aqueous phase by centrifugation. Most industrial installations in fact allow the simultaneous or sequential recovery of fruit juices and essential oil.

[0116] Essential oils are generally volatile and liquid at room temperature, which differentiates them from so-called fixed oils. They are more or less colored and their density is generally lower than that of water. They have a high refractive index and most of them deflect polarized light. They are liposoluble and soluble in the usual organic solvents, entrainable with water vapor, very slightly soluble in water.
