SULFATE ET SES UTILISATIONS SULPHATE AND ITS USES
[0001 ] Domaine technique [0001] Technical field
[0002] La présente invention se rapporte à une composition de surfactant [0002] The present invention relates to a surfactant composition
comprenant au moins un tensio-actif anionique et au moins un composé choisi parmi les tensio-actifs amphotères et les tensio-actifs non-ioniques, ainsi qu’à une composition cosmétique, dermatologique ou détergente comprenant une composition de surfactant de l’invention. comprising at least one anionic surfactant and at least one compound chosen from amphoteric surfactants and nonionic surfactants, as well as a cosmetic, dermatological or detergent composition comprising a surfactant composition of the invention.
[0003] La présente invention trouve des applications notamment dans le domaine de la cosmétique et du nettoyage en général. [0003] The present invention finds applications in particular in the field of cosmetics and cleaning in general.
[0004] Etat de la technique [0004] State of the art
[0005] Peu utilisé il y a une vingtaine d’années, le gel douche est progressivement devenu un produit d’hygiène corporel quotidien du fait de la sensation agréable qu’il procure sur la peau, des parfums variés proposés et de sa praticité d’utilisation. Little used twenty years ago, the shower gel has gradually become a daily personal hygiene product because of the pleasant sensation it provides on the skin, the various fragrances offered and its practicality of use. 'use.
[0006] Les gels douche sont généralement conditionnés dans des flacons, [0006] Shower gels are generally packaged in bottles,
éventuellement munis de pompe, ou dans des tubes souples. Ils sont possibly fitted with a pump, or in flexible tubes. They are
généralement formulés pour avoir une viscosité, se présentant sous forme de gel, ceci afin de permettre leur distribution soit par versement à partir d’un flacon, soit par pression d’un tube souple ou par pression exercée sur la pompe d’un flacon pompe. Le gel est généralement dilué avec de l’eau au moment de l’application sur la peau, ce qui permet également la formation d’une mousse lors du massage ou de la friction du produit avec la peau. generally formulated to have a viscosity, in the form of a gel, in order to allow their distribution either by pouring from a bottle, or by pressure from a flexible tube or by pressure exerted on the pump of a pump bottle . The gel is usually diluted with water at the time of application to the skin, which also allows foam to form when massaging or rubbing the product against the skin.
[0007] Toutefois, les préoccupations environnementales prennent une importance grandissante dans le domaine cosmétique. Un gel douche classique contenant au moins 85% d’eau, on cherche actuellement, pour des raisons écologiques, à réduire la quantité d’eau dans ce type de produits cosmétiques, afin d’une part de diminuer la quantité d’eau transportée, et d’autre part de diminuer les quantités d’emballage. [0008] Ainsi, un des moyens pour diminuer la quantité d’eau dans les produits cosmétiques est de les concentrer. [0007] However, environmental concerns are becoming increasingly important in the cosmetics field. A classic shower gel containing at least 85% water, we are currently seeking, for ecological reasons, to reduce the amount of water in this type of cosmetic products, in order on the one hand to reduce the amount of water transported, and on the other hand to reduce the quantities of packaging. [0008] Thus, one of the means for reducing the quantity of water in cosmetic products is to concentrate them.
[0009] Il existe des produits d’hygiène corporelle concentrés sur le marché, même s’ils sont beaucoup moins répandus que dans le domaine de la détergence (lessives, liquides vaisselle concentrés, etc.). [0009] There are concentrated personal hygiene products on the market, although they are much less common than in the field of detergents (washing powders, concentrated dishwashing liquids, etc.).
[0010] Dans les années 90, la marque Gühl proposa une gamme de shampooings concentrés transparents en flacon avec capsule service. In the 90s, the Gühl brand offered a range of transparent concentrated shampoos in a bottle with a service cap.
[0011] La limite de ces produits concerne leur application. En effet, il est difficile d’étaler une très petite quantité de produit sur une large surface et, ce, d’autant plus que la viscosité du produit est élevée. Cela retarde la dilution du produit avec l’eau et donc l’apparition de la mousse. [0011] The limit of these products concerns their application. This is because it is difficult to spread a very small amount of product over a large area, especially as the viscosity of the product is high. This delays the dilution of the product with water and therefore the appearance of foam.
[0012] En parallèle, il existe une autre attente forte des consommateurs concernant les produits de type gel douche : en effet, ils exigent de plus en plus de naturalité dans les produits qu’ils utilisent, notamment lorsque ceux-ci sont utilisés quotidiennement et directement sur la peau. A ce titre, les sulfates font actuellement l’objet de controverses. En effet, présents dans la plupart des produits moussants comme les gels douche, les produits capillaires et les détergents, les sulfates sont des tensio-actifs qui moussent beaucoup et qui ont un fort pouvoir nettoyant. Ainsi, utilisés quotidiennement, certains tensio-actifs sulfatés stimuleraient la production de sébum, favoriseraient les points noirs, seraient irritants pour la peau et le cuir chevelu et accéléreraient la dégradation des colorations capillaires. Les consommateurs sont ainsi en attente de produits d’hygiène corporels plus naturels, donc plus respectueux de l’environnement, et présentant une meilleure tolérance pour un plus large public. [0012] At the same time, there is another strong expectation from consumers concerning products of the shower gel type: in fact, they demand more and more naturalness in the products they use, in particular when they are used daily and directly on the skin. As such, sulphates are currently the subject of controversy. Indeed, present in most foaming products such as shower gels, hair products and detergents, sulphates are surfactants which foam a lot and which have a strong cleaning power. Thus, used daily, certain sulphated surfactants stimulate the production of sebum, promote blackheads, irritate the skin and scalp and accelerate the degradation of hair color. Consumers are therefore waiting for more natural body hygiene products, therefore more respectful of the environment, and having better tolerance for a wider public.
[0013] Il existe donc un réel besoin de produits d’hygiène corporel palliant ces [0013] There is therefore a real need for personal hygiene products that overcome these
défauts, inconvénients et obstacles de l’art antérieur, de façon à améliorer leur impact sur l’environnement et la santé humaine. defects, drawbacks and obstacles of the prior art, so as to improve their impact on the environment and human health.
[0014] Description de l’invention [0014] Description of the invention
[0015] Aux termes d’importantes recherches, la Demanderesse est parvenue à [0015] According to extensive research, the Applicant has succeeded in
mettre au point un produit d’hygiène corporel, notamment de la peau et des cheveux, répondant précisément à ces besoins en fournissant une composition rhéofluidifiante sans sulfate concentrée en tensio-actifs. develop a personal hygiene product, especially for the skin and hair, meeting these needs precisely by providing a shear-thinning composition without sulfate concentrated in surfactants.
[0016] Cette composition a la propriété de se fluidifier à l’étalement. Les propriétés rhéologiques de la composition selon l’invention permettent non seulement un étalement aisé sur la peau et/ou les cheveux, mais également de dispenser la composition par un dispositif générateur de spray, si cela est souhaité par l’utilisateur. [0016] This composition has the property of becoming fluid on spreading. The rheological properties of the composition according to the invention not only allow easy spreading on the skin and / or the hair, but also to dispense the composition by a spray-generating device, if this is desired by the user.
[0017] Avantageusement, la diffusion en spray améliore encore la répartition de la composition sur le corps et la vitesse de dilution avec l’eau, pour permettre un moussage rapide. D’autre part, la faible viscosité de la formule permet une utilisation complète du produit concentré : il reste peu de produit dans le flacon plastique en fin d’utilisation : le taux de restitution est optimal. [0017] Advantageously, the spray diffusion further improves the distribution of the composition on the body and the rate of dilution with water, to allow rapid foaming. On the other hand, the low viscosity of the formula allows full use of the concentrated product: there is little product left in the plastic bottle at the end of use: the return rate is optimal.
[0018] Avantageusement, la composition selon l’invention est concentrée environ 4 fois en tensio-actifs, c'est-à-dire en matière active moussante, par rapport à un gel douche classique. Plus largement entre 3 et 5 et encore plus largement de 2 à 6. Advantageously, the composition according to the invention is concentrated about 4 times in surfactants, that is to say in foaming active material, compared to a conventional shower gel. More broadly between 3 and 5 and even more broadly from 2 to 6.
[0019] La composition de l’invention présente donc l’avantage d’être plus écologique que les produits d’hygiène corporel de type gels existants, puisque pouvant se présenter dans un format plus réduit. [0019] The composition of the invention therefore has the advantage of being more environmentally friendly than existing gel-type body hygiene products, since they can be presented in a smaller format.
[0020] De plus, la composition de l’invention permet de se passer de conservateur, pour un bénéfice d’innocuité pour le consommateur, et pour réduire l’impact sur l’environnement. [0020] In addition, the composition of the invention eliminates the need for a preservative, for the benefit of safety for the consumer, and to reduce the impact on the environment.
[0021] Du fait de sa concentration plus élevée que celle des produits d’hygiène [0021] Due to its higher concentration than that of hygiene products
corporelle de type gels existants, les volumes de produits transportés sont divisés par 4, ce qui abaisse d’autant les émissions de CO2 pendant le transport. body gel, the volumes of products transported are divided by 4, which further reduces CO2 emissions during transport.
[0022] La réduction des volumes fabriqués permet également de réduire les [0022] The reduction in the volumes produced also makes it possible to reduce
capacités de stockage des produits d’un facteur 4. product storage capacities by a factor of 4.
[0023] Les emballages étant réduits par rapport à un produit classique, la The packaging being reduced compared to a conventional product, the
Demanderesse estime que la consommation de plastique dans ce cadre est diminuée de 50% par rapport à un produit de type gel classique. [0024] Du fait de son format réduit, le produit d’hygiène corporel résultant de l’invention est plus pratique d’utilisation, car moins lourd et plus transportable. Il peut dans ce cadre être plus facilement utilisé dans le cadre d’un voyage, ou d’une utilisation en dehors de la maison du type activités sportives. Applicant estimates that the consumption of plastic in this context is reduced by 50% compared to a product of conventional gel type. Due to its small size, the body hygiene product resulting from the invention is more practical to use, because it is less heavy and more transportable. In this context, it can be more easily used as part of a trip, or for use outside the home for sports activities.
[0025] Par ailleurs, il présente les mêmes avantages qu’un gel douche [0025] Furthermore, it has the same advantages as a shower gel
classique. Il présente notamment une viscosité comparable aux produits d’hygiène moussante classiques et une bonne stabilité dans le temps. Par ailleurs, l’application du produit d’hygiène sur la peau ou les cheveux mouillés produit une mousse agréable, comme celle formée par un gel de douche classique. classic. In particular, it has a viscosity comparable to conventional foaming hygiene products and good stability over time. Furthermore, the application of the hygiene product to wet skin or hair produces a pleasant foam, like that formed by a conventional shower gel.
[0026] La Demanderesse a mis en évidence que les propriétés rhéo-fluidifiantes de la composition de l’invention sont liées à sa structure physico-chimique. Sans vouloir être liée par un mécanisme d’action particulier, la Demanderesse a mis en évidence que la composition de l'invention est un milieu tensioactif "structuré". En d'autres termes, les tensioactifs contenus dans la composition sont organisés dans une phase lyotrope de type cristal-liquide, encore appelée mésophase. La phase est anisotrope optiquement et apparaît biréfringente lorsqu'elle est observée en lumière polarisée avec un microscope optique. Plus précisément, il s'agit d'une phase lamellaire, où les tensioactifs sont organisés en bicouches encore appelées lamelles. Les bicouches forment un empilement périodique en étant séparées les unes des autres par des couches d'eau intermédiaires. Les mélanges tensio-actifs présentant des phases lamellaires sont généralement des liquides non newtoniens pouvant être pompés, qui ont une apparence trouble. The Applicant has demonstrated that the rheo-thinning properties of the composition of the invention are linked to its physicochemical structure. Without wishing to be bound by a particular mechanism of action, the Applicant has demonstrated that the composition of the invention is a "structured" surfactant medium. In other words, the surfactants contained in the composition are organized in a lyotropic phase of the liquid crystal type, also called the mesophase. The phase is optically anisotropic and appears birefringent when viewed in polarized light with an optical microscope. More precisely, it is a lamellar phase, where the surfactants are organized in bilayers also called lamellae. The bilayers form a periodic stack being separated from each other by intermediate water layers. Surfactant mixtures with lamellar phases are generally non-Newtonian pumpable liquids which have a cloudy appearance.
[0027] De plus, au terme de ses recherches, la Demanderesse a réussi à obtenir ces caractéristiques de rhéo-fluidification avec des tensio-actifs sans sulfate, et qui ne présentent pas les inconvénients en terme d’irritation de la peau et du cuir chevelu des tensio-actifs sulfatés. In addition, at the end of its research, the Applicant has succeeded in obtaining these rheo-thinning characteristics with sulphate-free surfactants, and which do not have the drawbacks in terms of irritation of the skin and of the leather. hairy sulfated surfactants.
[0028] Ainsi, un premier objet de l’invention se rapporte à une composition de [0028] Thus, a first object of the invention relates to a composition of
surfactant comprenant : surfactant comprising:
a) au moins un tensio-actif anionique, et b) au moins un composé choisi parmi les tensio-actifs amphotères et les tensio-actif non-ioniques, a) at least one anionic surfactant, and b) at least one compound chosen from amphoteric surfactants and nonionic surfactants,
dans laquelle la matière active totale des dits tensio-actifs est comprise de 25 à 70% en poids par rapport au poids total de la dite composition, in which the total active material of said surfactants is from 25 to 70% by weight relative to the total weight of said composition,
dans laquelle le ratio de tensio-actif anionique est compris de 0,2 à 0,9, le ratio de tensio-actif amphotère est compris de 0,0 à 0,8 et le ratio de tensio-actif non-ionique est compris de 0,0 à 0,8, ledit ratio étant le rapport entre le pourcentage en poids de matière active dudit tensio-actif dans ladite composition et le pourcentage en poids de matière active totale desdits tensio-actifs dans ladite composition, wherein the ratio of anionic surfactant is from 0.2 to 0.9, the ratio of amphoteric surfactant is from 0.0 to 0.8 and the ratio of nonionic surfactant is from 0.0 to 0.8, said ratio being the ratio between the percentage by weight of active material of said surfactant in said composition and the percentage by weight of total active material of said surfactants in said composition,
le pH de la composition étant compris entre 4 et 9, the pH of the composition being between 4 and 9,
dans laquelle ledit au moins un tensio-actif anionique est choisi dans le groupe comprenant un alkyl sulfoacétate, un iséthionate et un sarcosinate. wherein said at least one anionic surfactant is selected from the group comprising an alkyl sulfoacetate, an isethionate and a sarcosinate.
[0029] Avantageusement, la composition de surfactant de l’invention est dépourvue de tensio-actif sulfaté. On entend par « dépourvue de tensio-actif sulfaté » ou « composition sans sulfate », au sens de la présente invention, que la [0029] Advantageously, the surfactant composition of the invention is devoid of sulphated surfactant. The term “free of sulfated surfactant” or “sulfate-free composition” is understood to mean, within the meaning of the present invention, that the
composition de surfactant de l'invention est exempte, c'est-à-dire ne contient aucun tensioactif sulfaté. Les tensio-actifs ainsi visés sont notamment les tensio- actifs anioniques dérivés d'un sulfate, comme le lauryl sulfate de sodium (SLS), le laureth sulfate de sodium (SLES), le lauryl sulfate d'ammonium (ALS) ou le laureth sulfate d'ammonium (ALES), et plus généralement les tensio-actifs comprenant au moins un groupe sulfaté ou un groupe pouvant être ionisé en un groupe sulfaté, notamment choisi parmi les fonctions sulfate (-OSO3H ou - OSO3-). surfactant composition of the invention is free, i.e., contains no sulfated surfactant. The surfactants thus targeted are in particular anionic surfactants derived from a sulfate, such as sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES), ammonium lauryl sulfate (ALS) or laureth ammonium sulphate (ALES), and more generally surfactants comprising at least one sulphated group or a group which can be ionized to a sulphated group, in particular chosen from sulphate functions (-OSO3H or - OSO3-).
[0030] On entend par « matière active », au sens de la présente invention, le tensio- actif présent dans la matière première commerciale contenant le tensio-actif. La matière active est ainsi à l’origine des propriétés tensio-actives de la matière première contenant le tensio-actif. La matière première, généralement distribuée par un fournisseur, contient, en plus de la matière active ayant les propriétés tensio-actives, d’autres composants, comme par exemple de l’eau ou des solvants, des résidus réactionnels et des produits annexes. Le pourcentage de matière active dans une matière première s’obtient en soustrayant le pourcentage d’eau ou solvant, les résidus réactionnels et les produits annexes contenus dans la matière première pour ne compter que le pourcentage du tensio-actif. [0030] For the purposes of the present invention, the term “active material” means the surfactant present in the commercial raw material containing the surfactant. The active material is thus at the origin of the surfactant properties of the raw material containing the surfactant. The raw material, generally distributed by a supplier, contains, in addition to the active material having surface-active properties, other components, such as for example water or solvents, reaction residues and related products. The percentage of active ingredient in a raw material is obtained by subtracting the percentage of water or solvent, reaction residues and related products contained in the raw material to count only the percentage of the surfactant.
[0031] On entend par « matière active totale », au sens de la présente invention, la somme des matières actives présentes dans chaque matière première contenant chaque tensio-actif, et comprises dans la composition de surfactant de For the purposes of the present invention, the term “total active material” means the sum of the active materials present in each raw material containing each surfactant, and included in the surfactant composition of
l’invention. the invention.
[0032] Selon l’invention, la matière active totale des tensio-actifs peut être comprise de 25 à 70% en poids par rapport au poids total de la composition, par exemple de 25 à 35%, ou de 30 à 55%, ou de 35 à 45%, ou de 30 à 35%, ou de 35 à 40%, ou de 30 à 40% ou de 35 à 60%. According to the invention, the total active material of the surfactants can be from 25 to 70% by weight relative to the total weight of the composition, for example from 25 to 35%, or from 30 to 55%, or 35-45%, or 30-35%, or 35-40%, or 30-40% or 35-60%.
[0033] La composition de l’invention a un pH compris de 4,0 à 9,0, les bornes étant incluses. Le pH peut être par exemple compris de 4,5 à 8,5, ou entre 5,0 et 8,0, ou entre 5,5 et 8,5, ou entre 6,0 et 8,0, les bornes étant incluses. [0033] The composition of the invention has a pH of 4.0 to 9.0, the limits being included. The pH can be for example between 4.5 and 8.5, or between 5.0 and 8.0, or between 5.5 and 8.5, or between 6.0 and 8.0, the limits being included .
Avantageusement, le pH peut être un pH physiologique compris entre 5,0 et 6,0, les bornes étant incluses. Advantageously, the pH can be a physiological pH of between 5.0 and 6.0, the limits being included.
[0034] Avantageusement, la composition de surfactant de l’invention présente un bon écoulement : la composition est fluide et s’écoule par simple inclinaison du flacon : cela se traduit par une mesure au viscosimètre rotatif Brookfield de type LV, d’une viscosité avantageusement < 20000 cps, voire inférieure à 5000 cps, ou inférieure à 3000 cps, ou même inférieure à 2500 cps, mesurée à la vitesse 6 avec les mobiles 2 3 ou 4 à l’issue d’un temps de mesure de 1 mn. Ce bon écoulement se traduit généralement par une bonne rhéofluidification, ce qui peut être observé pendant le temps de la mesure : la viscosité diminue pendant l’intervalle de 1 mn du temps de mesure. Advantageously, the surfactant composition of the invention exhibits good flow: the composition is fluid and flows by simply tilting the bottle: this results in a measurement with a Brookfield rotary viscometer of the LV type, of a viscosity advantageously <20,000 cps, or even less than 5,000 cps, or less than 3,000 cps, or even less than 2,500 cps, measured at speed 6 with the moving parts 2 3 or 4 after a measurement time of 1 min.

[0065] Quelle que soit la composition de l’invention telle que définie ci-avant, celle-ci peut en outre comprendre au moins un parfum. On entend par « parfum », au sens de la présente invention, une matière première parfumante ou un mélange de matières premières parfumantes, également nommé « concentré parfum », d’origine naturelle et/ou synthétique, solubilisées ou non dans un solvant pour matières premières de parfumerie. En d’autres termes, il peut s’agir de toute composition odorante ou de tout mélange de matières premières odorant, présentant des caractéristiques olfactives compatibles avec une utilisation en cosmétique, généralement fortement concentrée, généralement proposée conditionnée par un parfumeur. Le solvant peut être tout solvant adapté connu de l’homme du métier, comme par exemple l’éthanol, le Dipropylene glycol, le triéthylcitrate, le myristate d’isopropyl, la triacétine, cette liste n’étant pas limitative. Les matières premières d’origine naturelle peuvent être toute matière première adaptée connue de l’homme du métier, par exemple les huiles essentielles, les concrètes, les absolus ou les extraits végétaux. Les proportions entre solvant et matières premières odorantes peuvent être très variables selon la puissance olfactive des matières premières odorantes et leur solubilité, selon ce qui est classiquement réalisé dans le domaine des parfums, connu de l’homme du métier. Selon l’invention, la composition peut ainsi comprendre en outre du parfum dont le pourcentage en poids dans la composition peut aller de 0,0 à 10% en poids par rapport au poids total de ladite composition, les bornes étant incluses, par exemple de 0,05 à 10 %, ou de 0,1 à 10%, ou de 0,5 à 10%, ou de 0,5 à 5,0%, ou de 1 ,0 à 5,0%, ou de 1 à 10%, ou de 2 à 10%, ou de 3 à 10%, ou de 5 à 10%. Le parfum peut être toute composition parfumante commerciale, par exemple Parfum citron Basilic (Givaudan) ou Parfum Baie acidulée (Robertet). Avantageusement, le parfum peut conduire à baisser la viscosité du mélange de tensio-actif pour obtenir un produit plus fluide, et/ou d’abaisser le seuil d’écoulement de la composition, ce qui améliore la [0065] Whatever the composition of the invention as defined above, the latter can also comprise at least one perfume. For the purposes of the present invention, the term “perfume” means a perfuming raw material or a mixture of perfuming raw materials, also called a “perfume concentrate”, of natural and / or synthetic origin, whether or not dissolved in a solvent for materials. perfumery firsts. In other words, it can be any fragrant composition or any mixture of fragrant raw materials, exhibiting olfactory characteristics compatible with use in cosmetics, generally highly concentrated, generally offered packaged by a perfumer. The solvent can be any suitable solvent known to those skilled in the art, such as, for example, ethanol, dipropylene glycol, triethyl citrate, isopropyl myristate, triacetin, this list not being limiting. The raw materials of natural origin can be any suitable raw material known to those skilled in the art, for example essential oils, concretes, absolutes or plant extracts. The proportions between solvent and odorous raw materials can be very variable depending on the olfactory power of the fragrant raw materials and their solubility, according to what is conventionally achieved in the field of perfumes, known to those skilled in the art. According to the invention, the composition may thus further comprise perfume, the percentage by weight of which in the composition may range from 0.0 to 10% by weight relative to the total weight of said composition, the limits being included, for example of 0.05 to 10%, or 0.1 to 10%, or 0.5 to 10%, or 0.5 to 5.0%, or 1.0 to 5.0%, or 1 at 10%, or from 2 to 10%, or from 3 to 10%, or from 5 to 10%. The perfume can be any commercial perfume composition, for example Lemon Basil Perfume (Givaudan) or Acid Berry Perfume (Robertet). Advantageously, the perfume can lead to lowering the viscosity of the surfactant mixture to obtain a more fluid product, and / or lowering the flow threshold of the composition, which improves the
sprayabilité. [0066] Dans un mode de réalisation, quels que soient les tensio-actifs choisis, la composition de surfactant peut être dépourvue de chlorure de sodium autre que celui pouvant être apporté par les tensio-actifs. Dans ce cas, il n’est pas ajouté de chlorure de sodium en tant que tel lors de la préparation de la composition de surfactant de l’invention. Toutefois, les compositions de tensio-actifs faisant parties de la composition peuvent en contenir, ce qui implique qu’une faible quantité de chlorure de sodium puisse éventuellement être détectée, notamment à l’état de trace, dans la composition de surfactant de l’invention. Il peut s’agir par exemple d’environ 0,0 à environ 6,0%-en poids de chlorure de sodium venant des compositions de tensio-actifs, par rapport au poids total de ladite sprayability. In one embodiment, whatever the surfactants chosen, the surfactant composition may be devoid of sodium chloride other than that which may be provided by the surfactants. In this case, sodium chloride as such is not added during the preparation of the surfactant composition of the invention. However, the surfactant compositions forming part of the composition may contain them, which implies that a small amount of sodium chloride can optionally be detected, in particular in a trace state, in the surfactant composition of the invention. It may be, for example, from about 0.0 to about 6.0% by weight of sodium chloride coming from the surfactant compositions, relative to the total weight of said
composition, par exemple entre 0,001 et 6,0%, ou 0,005 et 1 ,0%, ou 0,01 et 1 ,0%, ou 0,05 et 1 ,0%, ou 0,05 et 0,1 %. L’absence d’ajout de chlorure de sodium confère de manière avantageuse une meilleure innocuité de la composition par rapport aux produits classiques, dans lesquels du chlorure de sodium est ajouté. composition, for example between 0.001 and 6.0%, or 0.005 and 1.0%, or 0.01 and 1.0%, or 0.05 and 1.0%, or 0.05 and 0.1%. The absence of addition of sodium chloride advantageously confers better safety of the composition compared with conventional products, in which sodium chloride is added.

Par exemple, la composition de l’invention peut comprendre d’environ 0,001 à 8,0%, ou d’environ 0,1 à 4,0%, ou d’environ 0,5 à 4,0%, ou d’environ 1 ,0 à 3,0, ou d’environ 1 ,0 à 4,0%, ou d’environ 1 ,0 à 6,5%, ou d’environ 2,0 à 6,0%. Par exemple, la composition de l’invention peut In another embodiment, regardless of the surfactants chosen, the composition of the invention may further comprise from 0.0 to 8.0% of sodium chloride other than that which may be provided by the surfactants, the value of 0.0% being excluded. For example, the composition of the invention may comprise from about 0.001 to 8.0%, or from about 0.1 to 4.0%, or from about 0.5 to 4.0%, or from about 1.0 to 3.0, or about 1.0 to 4.0%, or about 1.0 to 6.5%, or about 2.0 to 6.0%. For example, the composition of the invention may
comprendre 4,0%, ou 5,0%, ou 6,0%, ou 7,0%, ou 8,0% de chlorure de sodium autre que celui pouvant être apporté par les tensio-actifs. comprise 4.0%, or 5.0%, or 6.0%, or 7.0%, or 8.0% of sodium chloride other than that which may be provided by the surfactants.

[Tableau 9] [Table 9]
[0126] La composition telle que décrite dans le tableau 9 présente l’avantage de montrer une viscosité régulée, qui reste inférieure à 2500 cps, quel que soit le parfum testé (mangue, coco, vanille et grenade). [0127] A titre d’exemple, un comparatif entre la viscosité mesurée pour la composition du tableau 9, et la viscosité mesurée pour la même composition dans laquelle le décylglucoside est remplacé par de la glycérine en même proportion dans la composition (nommée « Comparatif 5% glycérine »), est donné au tableau 10. The composition as described in Table 9 has the advantage of showing a regulated viscosity, which remains less than 2500 cps, whatever the flavor tested (mango, coconut, vanilla and pomegranate). [0127] By way of example, a comparison between the viscosity measured for the composition in Table 9, and the viscosity measured for the same composition in which the decylglucoside is replaced by glycerin in the same proportion in the composition (called "Comparative 5% glycerin ”), is given in Table 10.
[0128] Les viscosités sont mesurées au viscosimètre rotatif Brookfield de type LVT vitesse 6, mobile 2, 3 ou 4 selon la gamme de viscosité : 2000cps (mobile2) 6000cps (mobile 3) 18000cps (mobile 4). [0128] The viscosities are measured with a Brookfield rotary viscometer of LVT speed 6 type, mobile 2, 3 or 4 depending on the viscosity range: 2000cps (mobile2) 6000cps (mobile 3) 18000cps (mobile 4).
[0129] [Tableau 10] [0129] [Table 10]
[0130] La viscosité mesurée pour la composition « Comparatif 5% glycérine » varie fortement, de 1560 cps pour le parfum vanille, à 14600 cps pour le parfum mangue, alors que la viscosité de la composition selon l’invention reste conforme à la viscosité recherchée, avec une viscosité inférieure à 2500 cps quel que soit le parfum utilisé. La composition telle que décrite dans le tableau 9 présente ainsi une capacité d’écoulement et une rhéofluidification conformes à l’effet technique recherché selon l’invention. The viscosity measured for the composition "Comparative 5% glycerin" varies greatly, from 1560 cps for the vanilla perfume, to 14600 cps for the mango perfume, while the viscosity of the composition according to the invention remains in conformity with the viscosity desired, with a viscosity of less than 2500 cps whatever the perfume used. The composition as described in Table 9 thus exhibits a flow capacity and shear thinning in accordance with the technical effect sought according to the invention.
