Description

Title of the invention: Cosmetic composition comprising a combination of alkyl polyglucosides Technical field

[0001] The present invention aims to propose a new composition, preferably cosmetic, in particular perfumed, for the field of care and / or hygiene of keratin materials, in particular of the skin of the face and / or body or hair.

[0002] It aims more particularly to propose a cleaning product for keratin materials, preferably a shower gel or a facial cleansing product, natural and capable of solubilizing one or more perfumed substances while retaining a clear appearance and organoleptic properties, in particular an odor, acceptable to users. Prior art

[0003] 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.

[0004] In this respect, consumers and formulators of cosmetic compositions are keen to free themselves as much as possible from so-called "chemical" products in favour of so-called "natural" products which are advantageously non-persistent in the environment, to limit the number of ingredients in these compositions, but also to favour the processes for preparing these compositions which require the least energy.

[0005] As cosmetic products, cleaning products for keratinous materials, such as skin and hair, are very important for removing oily residues, such as excess sebum or remains of cosmetic products used daily, which accumulate in the skin folds and are responsible in particular for the obstruction of the pores of the skin.

[0006] Thus, the use of detergent cosmetic compositions, for example of the shampoo or shower gel type, based essentially on surfactants, is common. These compositions are generally applied to keratin materials, preferably wet, and the foam generated by massage or friction with the hands or a washcloth allows, after rinsing with water, the elimination of various dirt initially present on the hair or skin.

[0007] In particular, it is common to introduce into cosmetic compositions cleaning of keratin materials with anionic surfactants, particularly of the sulfate type, which are very good detergent surfactants.

[0008] Nevertheless, sulfates can be unfriendly to the keratin materials to be washed, in particular by having a drying effect on said materials, or even by negatively impacting the conditioning of the hair or skin, especially in certain sensitive consumers. The alteration of the cosmetic properties of the hair or skin thus leads to combining sulfates with conditioning agents such as cationic polymers, silicones or non-silicone oils.

[0009] It is also well known that cosmetic cleansing compositions may contain a certain level of non-ionic surfactant(s), for example, non-biodegradable surfactants based on polyethylene glycol (PEG). Furthermore, depending on the method of preparation, PEG may be contaminated with measurable amounts of 1,4-dioxane which may persist in the environment for a long time, due to its difficult decomposition. Furthermore, 1,4-dioxane is a regulated chemical substance due to its suspected toxicity.

[0010] Cleaning compositions comprising at least one polyalkyl-glucoside surfactant have already been proposed, in particular because these surfactants are derived from renewable raw materials and are biodegradable, for example in document EP 2 217 203.

[0011] Furthermore, it has been envisaged to propose cosmetic compositions having a novel visual appearance, namely compositions that are particularly clear, or even transparent. Indeed, a clear and transparent cleansing cosmetic composition is generally associated by consumers with freshness, softness, purity, cooling, cleanliness, etc. Transparent products are therefore used for a variety of personal care applications. Furthermore, a transparent product, when packaged in transparent packaging, allows consumers to see the entire product.

[0012] An example of a transparent cleaning composition is described in document FR 3 106 753, and comprises a combination of anionic and amphoteric surfactants and from 0.5% to 2.5% by weight of at least one diol with a C3-C6 hydrocarbon chain.

[0013] However, the introduction of perfuming substances, in particular in contents greater than or equal to 1% by weight, has a negative impact on the clarity of the cosmetic compositions containing them, in particular in the presence of very hydrophilic surfactants. Statement of the invention

[0014] Thus, there remains a need to have clear cosmetic compositions, intended for cleaning and / or caring for keratin materials, not comprising of controversial ingredients and which may contain one or more perfume substances, in particular in contents greater than or equal to 1% by weight.

[0015] In particular, there is a need to have such compositions whose clear appearance and organoleptic properties, in particular in terms of odor, are preserved over time.

[0016] Furthermore, there is a need to have compositions for cleaning keratin materials, in particular of the shower gel type, which are natural and clear, having improved sensory properties, in particular in terms of softness.

[0017] Finally, there also remains a need to have compositions compatible with current consumer requirements, particularly from an environmental point of view.

[0018] The present invention aims precisely to meet these needs. Summary of the invention

[0019] Thus, according to a first of its aspects, the present invention relates to a composition, preferably cosmetic, in particular perfumed, comprising at least: a) at least one C9-C[4]alkyl polyglucoside; b) at least one C6-C8 alkyl polyglucoside; and c) at least one C2-C6 alkylene glycol, the weight ratio a) C9-C[4] alkyl polyglucoside to b) C6-C8 alkyl polyglucoside being strictly greater than 1.

[0020] In the remainder of the text, the term “alkylpolyglucosides according to the invention” will be used more simply to designate the combination of at least one C9-C[4] alkyl polyglucoside and at least one C6-C8 alkyl polyglucoside whose weight ratio is strictly greater than 1.

[0021] The inventors have found, surprisingly, that the combination of alkylpolyglucosides according to the invention and at least one C2-C6 alkylene glycol makes it possible to obtain a clear and homogeneous cosmetic cleaning composition, even in the presence of a content of perfume substances greater than 1% by weight, which retains its visual appearance and its organoleptic properties over time, in particular whose clear appearance and odor, in particular the perfumed notes, do not deteriorate over time, in particular for a period of up to several months.

[0022] Decylglucoside, caprylyl glucoside and propylene glycol have already been proposed in combination in skin cleansing compositions. However, these compositions do not have a clear visual appearance, which is precisely what is sought in the present application.

[0023] Thus, the invention also relates, according to another of its aspects, to the use a) of at least one C9-C[4] alkyl polyglucoside; b) of at least one C6-C8 alkyl polyglucoside; and c) of at least one C2-C6 alkylene glycol; the weight ratio of a) C9-C[4] alkyl polyglucoside to b) C6-C8 alkyl polyglucoside being strictly greater than 1, as solubilizing agents for at least one perfuming substance in a composition, preferably in a cosmetic composition, said perfuming substance being in particular present in a content greater than or equal to 1.0% by weight relative to the total weight of said composition.

[0024] For the purposes of the present invention, a “solubilizer” is intended to designate a compound making it possible to formulate a composition retaining its visual and organoleptic properties, in particular remaining clear or even transparent and retaining a pleasant odor for the consumer, in the presence of one or more perfuming substances, in particular present in the composition in a content greater than or equal to 1%, in particular in a content ranging from 1% to 4% by weight, relative to the total weight of the composition.

[0025] A composition according to the invention is suitable for topical administration, that is to say for application to the surface of keratin materials.

[0026] Thus, the invention also relates to a cosmetic process for the care and / or hygiene, in particular cleaning, of keratin materials comprising at least one step of applying a composition according to the invention to said keratin materials.

[0027] In particular, a composition according to the invention is suitable for cleaning and / or removing make-up from keratin materials, and as such can be in the form of a shower gel, a liquid or solid soap, etc.

[0028] Thus, the invention also relates to a cosmetic process for cleaning keratin materials, in particular the skin and / or hair, comprising at least one step of applying a composition according to the invention to said keratin materials, optionally in the presence of water, and optionally followed by a step of rinsing said composition, in particular with water.

[0029] It is understood that the cosmetic treatment methods referred to in the present application are non-therapeutic.

[0030] In the context of the present invention, and unless otherwise indicated, the definitions below apply.

[0031] By "keratin materials" is meant, according to the invention, the skin of the body, face and / or eye contour, lips, nails, mucous membranes, eyelashes, eyebrows, body hair, beard, scalp and / or hair, or any other skin area of ​​the body. More particularly, the keratin materials according to the invention are the scalp, hair and / or skin.

[0032] By "the skin" is meant the entire skin of the body, and preferably, the skin of the face, décolleté, neck, arms and forearms, or even more preferably, the skin of the face, in particular the forehead, nose, cheeks, chin, and eye contour.

[0033] The compositions according to the present invention are preferably cosmetic compositions. By "cosmetic" in the sense of the present invention, is meant a composition compatible with the skin, mucous membranes and appendages.

[0034] By "clear" in the sense of the present invention, it is meant that the composition lets light pass through and objects behind it appear clearly. In particular, it is transparent.

[0035] The transparency of the composition can be characterized using a 250 mL beaker into which the composition is introduced. The beaker is placed in a light box, for example of the Basic Color Viewing Light type from Just Normlicht. The composition is illuminated by a light simulating daylight or the light usually encountered in a store, for example in a supermarket. An object, such as a pen, or the hand is placed behind it at a distance of 0 to 3 cm; and by placing the eyes at a distance of between 20 cm and 40 cm, such as 30 cm, and perpendicular to the middle of the composition of said beaker, it is evaluated whether the object or the hand can be clearly distinguished through the composition in said beaker. Alternatively, it is directly evaluated whether the light source can be distinguished through the composition in the beaker.

[0036] Preferably, the transparency of the composition can be characterized by measuring its turbidity, using a Hach 2100Q portable turbidimeter at 25°C. The lower the turbidity value, expressed in NTU units, the clearer the composition.

[0037] Preferably, the turbidity of the compositions according to the invention, measured at room temperature (25°C) and atmospheric pressure, is less than 400 NTU units, more preferably between 1 and 250 NTU units, even better between 3 and 200 NTU units.

[0038] For the purposes of the present invention, the term “natural” is understood to mean 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 derived from a biotechnological process, in particular from cell or microbiological cultures, for example, fungi or bacteria. So-called “natural” compounds include compounds that are present in nature and that can be reproduced by chemical (semi)synthesis.

[0039] For the purposes of the present invention, the term “of natural origin” means any compound obtained from a natural substance which has undergone one or more treatments. chemical or industrial ancillary processes, resulting in modifications that do not affect the essential qualities of this substance. As a non-limiting example of chemical or industrial ancillary processing resulting in modifications that do not affect the essential qualities of a natural compound, we can mention 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.

[0040] 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.

[0041] By "perfumed composition" or "perfuming composition" within the meaning of the present invention, is meant any composition which leaves a perfume after application to keratin materials.

[0042] A perfume is the result of a combination of different odorous substances, each providing a specific diffusing odor or “note” and evaporating respectively at different times. More precisely, 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.

[0043] 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.

[0044] 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.

[0045] A “(Cx-Cz)alkyl” or “Cx-Cz alkyl” group represents 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.

[0046] A “(Cx-Cz)alkylene” or “Cx-Cz alkylene” group is a divalent group derived from a (Cx-Cz)alkyl group.

[0047] The expression “at least one” is equivalent to “one or more”.

[0059] The expressions "between ... and ...", "includes from ... to ...", "formed from ... to ...", and "ranging from ... to ..." must be understood inclusively, unless otherwise specified. Other characteristics, variants and advantages of the compositions according to the invention will become more apparent upon reading the description and examples which follow. Detailed description A composition, preferably cosmetic, according to the invention comprises a combination of at least two specific polyalkylglucosides, namely at least one C9-C14 alkyl polyglucoside and at least one C6-C8 alkyl polyglucoside. Alkyl polyglucosides, or alkylpolyglucosides (APGs), are known as non-ionic surfactants. These are compounds whose chemical structure is generally represented as follows: [Chem.l] The hydrophilic group (glucoside) preferably comprises from 1 to 4 saccharide units and the hydrophobic group (alkyl) may comprise from 6 to 30 carbon atoms. The alkyl group may be linear as shown above or branched. C9-C14 alkyl polyglucoside As mentioned above, a composition according to the invention comprises at least one C9-C14 alkyl polyglucoside. Preferably, the C9-C14 alkyl polyglucoside comprises 1, 2 to 3 saccharide units. It can be a single C9-C14 alkyl polyglucoside or a mixture of several C9-C14 alkyl polyglucosides. Preferably, it is a mixture of several C9-CM alkyl polyglucosides, in particular comprising at least one C10 alkyl polyglucoside, at least one C12 alkyl polyglucoside and at least one C14 alkyl polyglucoside. The C9-C14 alkyl polyglucoside(s) are preferably present in the composition according to the invention in a content ranging from 0.1 to 12% by weight, preferably from 0.5% to 10% by weight, more preferably from 1.5% to 8% by weight, such as from 4.5% to 5.5% by weight, relative to the total weight of the composition. C6-C8 alkyl polyglucoside

[0060] As mentioned previously, a composition according to the invention comprises at least one C6-C8 alkyl polyglucoside.

[0061] Preferably, the C6-C8 alkyl polyglucoside comprises 1, 2 to 3 saccharide units.

[0062] The alkyl group, linear or branched, comprises between 6 and 8 carbon atoms, preferably 8 carbon atoms.

[0063] It may be a single C6-C8 alkyl polyglucoside or a mixture of several C6-C8 alkyl polyglucosides. In particular, the C6-C8 alkyl polyglucoside comprises at least one C8 alkyl polyglucoside.

[0064] The C6-C8 alkyl polyglucoside(s) are preferably present in the composition according to the invention in a content ranging from 0.1% to 12% by weight, preferably from 0.5% to 5% by weight, more preferably from 1% to 4%, such as from 3% to 3.8% by weight, relative to the total weight of the composition.

[0065] As C9-C14 and / or C6-C8 alkyl polyglucosides which are particularly suitable for the invention, the following may be mentioned: - caprylyl / capryl glucoside, such as the product marketed under the name PLANTACARE 810 UP® by BASF, or under the name ORAMIX CG 110® by Seppic; and - decylglucoside, such as the product marketed under the name MYDOL 10® by the company Kao Chemicals, under the name PLANTAREN 2000 UP® by the company BASF, or under the name ORAMIX NS 10® by the company Seppic.

[0066] As mentioned previously, the alkylpolyglucosides are present in a composition according to the invention in contents making it possible to obtain a weight ratio of a) C9-C14 alkyl polyglucoside to b) C6-C8 alkyl polyglucoside being strictly greater than 1, particularly greater than 1.2, more particularly greater than 1.3. It is understood that the weight ratios of the invention are calculated as active material.

[0067] Advantageously, the weight ratio of a) C9-C14 alkyl polyglucoside to b) C6-C8 alkyl polyglucoside is between 1.1 and 10, preferably between 1 and 5, more particularly between 1 and 2.

[0068] According to a particular embodiment, a composition according to the invention comprises, as alkylpolyglucosides, a mixture of decyl glucoside and caprylyl / capryl glucoside.

[0069] Thus, the present invention relates, according to one of its aspects, to a composition, preferably cosmetic, in particular perfumed, comprising at least: (i) decyl glucoside; ii) caprylyl / capryl glucoside; And iii) at least one C2-C6 alkylene glycol; the weight ratio i) decyl glucoside to ii) caprylyl / capryl glucoside being strictly greater than 1, particularly greater than 1.2. It is understood that the weight ratios of the invention are calculated as active material. More particularly the ratio i) / ii) is between 1.1 and 10, preferably between 1 and 5, more particularly between 1 and 2.

[0070] The present invention also relates, according to one of its aspects, to a composition, preferably cosmetic, in particular perfumed, comprising at least:

[0071] i) at least one C8 alkyl polyglucoside; ii) at least one C10 alkyl polyglucoside; and iii) at least one C2-C6 alkylene glycol; the weight ratio i) C8 alkyl polyglucoside / ii) C10 alkyl polyglucoside being strictly greater than 1, particularly greater than 1.1. C2-C6 alkylene glycol

[0072] As mentioned previously, a composition according to the invention comprises at least one C2-C6 alkylene glycol.

[0073] For the purposes of the present invention, the term “glycol” is intended to denote a diol in which the two hydroxyl groups are carried by different carbon atoms, preferably by vicinal carbon atoms.

[0074] Examples of alkylene glycols suitable for the invention that may be cited are ethylene glycol, propylene glycol, butylene glycol, pentylene glycol, isoprene glycol, hexylene glycol, and mixtures thereof.

[0075] Preferably, the C2-C6 alkylene glycol is chosen from ethylene glycol, propylene glycol, butylene glycol, and mixtures thereof, more preferably is propylene glycol.

[0076] As a propylene glycol particularly suitable for the invention, mention may be made of the product marketed under the name 1,2-PROPYLENEGLYCOL CARE by the company BASF.

[0077] The alkylene glycol(s) may be present in a composition according to the invention in a content ranging from 5% to 40% by weight, preferably from 6% to 35% by weight, more preferably from 15% to 30% by weight, relative to the total weight of the composition. Perfume substance

[0078] As mentioned previously, a composition according to the invention is more particularly a perfumed composition.

[0079] A composition according to the invention therefore preferably comprises at least one perfuming substance.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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 result in a significant change in the composition.

[0085] 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.

[0086] 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".

[0087] 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.

[0088] 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.

[0089] 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 common organic solvents, entrainable by water vapor, very slightly soluble in water.

[0090] Among the essential oils that can be used according to the invention, mention may be made of those obtained from plants belonging to the following botanical families: Abietaceae or Pinaceae, for example conifers; Amaryllidaceae; Anacardiaceae; Anonaceae, for example ylang; Apiaceae, for example umbellifers, in particular dill, angenic, coriander, fennel, carrot or parsley; Araceae; Aristolochiaceae; Asteraceae for example yarrow, mugwort, chamomile, and helichrysum; Betulaceae; Brassicaceae; Burseraceae, for example frankincense; Caryophyllaceae; Canellaceae; Caesalpiniaceae for example copaifera (copahu); Chenopodaceae; Cistaceae for example cistus; Cyperaceae; Dipterocarpaceae; Ericaceae e.g. wintergreen; Euphorbiaceae; Fabaceae; Geraniaceae e.g. geranium; Guttiferae; Hamamelidaceae; Hernandiaceae; Hypericaceae e.g. St. John's wort; Iridaceae; Juglandaceae;Lamiaceae, e.g. thyme, oregano, bee balm, savory, basil, marjorams, mints, patchouli, lavenders, sages, catnip, rosemary, hyssop, lemon balm, rosemary; Lauraceae, e.g. ravensara, bay, rosewood, cinnamon, litsea; Liliaceae, e.g. garlic; Magnoliaceae, e.g. magnolia; Malvaceae; Meliaceae; Monimiaceae; Moraceae, for example hemp, or hops; Myricaceae; Mysristicaceae, for example nutmeg; Myrtaceae, for example eucalyptus, tea tree, niaouli, cajeput, backousia, clove, myrtle; Oleaceae; Piperaceae, for example pepper; Pittosporaceae; Poaceae, for example e.g. lemongrass, lemongrass, vetiver; Polygonaceae; Ranunculaceae; Rosaceae, e.g. roses; Rubiaceae; Rutaceae, e.g. all citrus; Salicaceae; Santalaceae, e.g. sandalwood; Saxifragaceae; Schisandraceae; Styracaceae, e.g. benzoin; Thymelaceae, e.g. agarwood; Tilliaceae; Valerianaceae, e.g. valerian, spikenard; Verbenaceae, e.g. lantana, verbena; Violaceae; Zingiberaceae, e.g. galangal, turmeric, cardamom, ginger; Zygophyllaceae.

[0093] A perfumed composition according to the invention preferably comprises a perfuming substance chosen from essential oils, perfumes and aromas of synthetic or natural origin, and mixtures thereof.

[0094] According to a preferred embodiment of the invention, a mixture of different perfuming substances is used which together generate a pleasant note for the user.

[0095] Thus, a composition according to the invention may advantageously comprise a mixture of perfuming substances, in particular of at least two distinct perfuming substances.

[0096] The perfuming substances will preferably be chosen so that they produce notes (head, heart and base) in the following families: citrus, aromatic, floral notes, particularly pink flowers and white flowers, spicy, woody, gourmand, chypre, fern, leather, oriental and musk.
