Description

COMPOSITION COSMETIQUE CAPILLAIRE PROCURANT DE BONNES PROPRIETES DE TENUE ET COMPRENANT DES POLYMERES FILMOGENES HAIR COSMETIC COMPOSITION PROVIDING GOOD HOLD PROPERTIES AND COMPRISING FILM-FORMING POLYMERS
L'invention a pour objet une composition cosmétique comprenant, dans un milieu cosmétiquement acceptable, au moins un polymère (A) aux caractéristiques particulières. Elle vise également un procédé de mise en forme ou de maintien des cheveux à l'aide de cette composition, ainsi que son utilisation pour la formulation de produits de coiffage tels que les laques, les sprays ou les mousses, en vue d'obtenir le maintien ou la mise en forme de la coiffure.The subject of the invention is a cosmetic composition comprising, in a cosmetically acceptable medium, at least one polymer (A) with particular characteristics. It also relates to a method of shaping or maintaining hair using this composition, as well as its use for the formulation of styling products such as hairsprays, sprays or mousses, with a view to obtaining the maintaining or shaping the hairstyle.
Parmi les produits capillaires pour la fixation des cheveux les plus répandus sur le marché de la cosmétique, on peut citer les compositions à pulvériser en aérosol ou en flacon pompe tels que les laques, les sprays ou les mousses, essentiellement constituées d'une solution le plus souvent alcoolique ou hydroalcooliquë" et d'un polymère filmogène soluble dans l'eau ou dans l'alcool, en mélange avec divers adjuvants cosmétiques.Among the hair products for fixing hair that are most widespread on the cosmetic market, there may be mentioned compositions for spraying in an aerosol or in a pump bottle, such as lacquers, sprays or foams, essentially consisting of a more often alcoholic or hydroalcoholic " and of a film-forming polymer soluble in water or in alcohol, in mixture with various cosmetic adjuvants.
Toutefois, ces formulations capillaires telles que les mousses, gels et surtout les sprays et les laques aérosols destinées à maintenir la forme de la coiffure ne permettent encore pas à la coiffure de résister de manière satisfaisante aux différents mouvements naturels de la vie comme la marche, les mouvements de tête ou les coups de vent.However, these hair formulations such as mousses, gels and especially sprays and aerosol lacquers intended to maintain the shape of the hairstyle do not yet allow the hairstyle to resist satisfactorily the various natural movements of life such as walking, head movements or gusts of wind.
Les polymères utilisés pour la formulation de ces produits capillaires sont des polymères filmogènes anioniques, amphotères ou non ioniques, qui conduisent à la formation de films possédant un caractère plus ou moins dur et cassant.The polymers used for the formulation of these hair products are anionic, amphoteric or nonionic film-forming polymers, which lead to the formation of films having a more or less hard and brittle nature.
Lorsque le polymère est trop cassant, le pourcentage d'allongement à la rupture mesuré sur le film est faible, c'est-à-dire en général inférieur à 2 % et la tenue de la coiffure n'est pas assurée dans le temps. Pour remédier à ce problème, on a déjà mélangé ces polymères avec des plastifiants et obtenu des revêtements plus souples et non friables. Toutefois, ces films sont déformables et plastiques, c'est-à-dire qu'après déformation, ils ne récupèrent que très peu de leur forme initiale. Si la tenue de la coiffure est améliorée, elle n'est pas encore satisfaisante puisque la forme de la coiffure évolue dans le temps.When the polymer is too brittle, the percentage of elongation at break measured on the film is low, that is to say generally less than 2% and the holding of the hairstyle is not ensured over time. To remedy this problem, these polymers have already been mixed with plasticizers and obtained more flexible and non-friable coatings. However, these films are deformable and plastic, that is to say that after deformation, they recover very little of their initial shape. If the holding of the hairstyle is improved, it is not yet satisfactory since the shape of the hairstyle changes over time.
Des résultats plus satisfaisants en terme de tenue ont été obtenus avec des compositions comprenant une association de polymères filmogènes, tels que par exemple un polymère polyvinylcaprolactame et un polymère acrylique. Toutefois, ces compositions ne donnent encore pas entièrement satisfaction, dans la mesure où les cheveux perdent certaines de leurs propriétés cosmétiques naturelles. En outre, il serait souhaitable d'augmenter encore le pouvoir fixant.More satisfactory results in terms of resistance have been obtained with compositions comprising a combination of film-forming polymers, such as for example a polyvinylcaprolactam polymer and an acrylic polymer. However, these compositions are not yet entirely satisfactory, insofar as the hair loses some of its natural cosmetic properties. In addition, it would be desirable to further increase the fixing power.
On recherche donc des compositions cosmétiques pour le maintien et/ou la fixation de la coiffure qui procurent à la chevelure, outre une fixation durable, de bonnes propriétés cosmétiques, notamment un bon démêlage, de la douceur et un aspect agréable.We are therefore looking for cosmetic compositions for maintaining and / or fixing the hairstyle which provide the hair, in addition to lasting fixation, with good cosmetic properties, in particular good disentangling, softness and a pleasant appearance.
De manière surprenante et inattendue, la Demanderesse a découvert qu'il était possible de remédier aux problèmes techniques évoqués ci-dessus, en utilisant des polymères particuliers.Surprisingly and unexpectedly, the Applicant has discovered that it is possible to remedy the technical problems mentioned above, by using specific polymers.
L'invention a pour objet une composition cosmétique comprenant, dans un milieu cosmétiquement acceptable, au moins un polymère filmogène (A) choisi de telle sorte que le matériau obtenu par séchage de ce polymère en milieu aqueux ou alcoolique, à température ambiante et à un taux d'humidité relative de 50 %, présente un profil mécanique défini par au moins:The subject of the invention is a cosmetic composition comprising, in a cosmetically acceptable medium, at least one film-forming polymer (A) chosen such that the material obtained by drying this polymer in an aqueous or alcoholic medium, at room temperature and at a relative humidity of 50%, has a mechanical profile defined by at least:
(a) un taux d'allongement à la rupture (εr) supérieur ou égal à 160 %;(a) a rate of elongation at break (ε r ) greater than or equal to 160%;
(b) une recouvrance instantanée (R;) comprise entre 10 et 68 %, (c) une recouvrance (R300) à 300 secondes comprise entre 30 et 100 %,(b) an instant recovery (R;) of between 10 and 68%, (c) a recovery (R300) at 300 seconds of between 30 and 100%,
(d) lorsque la recouvrance (R300) à 300 secondes est comprise entre 45 et 60 %, alors l'allongement à la rupture (εr) est inférieur à 1300 %, (e) un module d'Young supérieur à 10 M Pa, mesuré à une épaisseur de 0,5 mm et à une traction de 20 mm/min.(d) when the recovery (R300) at 300 seconds is between 45 and 60%, then the elongation at break (ε r ) is less than 1300%, (e) a Young's modulus greater than 10 M Pa, measured at a thickness of 0.5 mm and at a tension of 20 mm / min.
Un autre objet de la présente invention concerne un procédé de mise en forme ou de maintien de la coiffure comprenant la mise en œuvre de cette composition.Another object of the present invention relates to a method of shaping or maintaining the hairstyle comprising the use of this composition.
Encore un autre objet de la présente invention concerne l'utilisation de cette composition pour la fabrication de compositions cosmétiques capillaires, en vue d'obtenir un maintien ou une mise en forme de la coiffure.Yet another object of the present invention relates to the use of this composition for the manufacture of hair cosmetic compositions, with a view to obtaining maintenance or shaping of the hairstyle.
Les polymères (A) particulièrement visés par la présente invention sont ceux distribués par AIR PRODUCT sous l'appellation YAY IEG 973 et par SANYO sous l'appellation PA Marin UA 310.The polymers (A) particularly targeted by the present invention are those distributed by AIR PRODUCT under the name YAY IEG 973 and by SANYO under the name PA Marin UA 310.
Au sens de la présente invention, on entend par film obtenu par séchage à température ambiante (22 ± 2°C) et à un taux d'humidité relative de 50 % ± 5%, le film obtenu dans ces conditions à partir d'un mélange à 6 % de matière active (m. a.) de polymère A avec de l'éthanol ou de l'eau, la quantité de mélange étant adaptée pour obtenir dans une matrice en téflon, un film d'épaisseur de 500 ± 50 μm. Le séchage est poursuivi jusqu'à ce que le poids du film n'évolue plus, ce qui représente environ 12 jours. Les polymères A solubles ou partiellement solubles dans l'éthanol sont testés dans l'éthanol. Les autres polymères sont testés dans l'eau sous forme soluble ou dispersée.For the purposes of the present invention, the term film obtained by drying at room temperature (22 ± 2 ° C) and at a relative humidity level of 50% ± 5% means the film obtained under these conditions from a mixture with 6% of active material (ai) of polymer A with ethanol or water, the quantity of mixture being adapted to obtain, in a teflon matrix, a film with a thickness of 500 ± 50 μm. Drying is continued until the weight of the film no longer changes, which represents approximately 12 days. Polymers A soluble or partially soluble in ethanol are tested in ethanol. The other polymers are tested in water in soluble or dispersed form.
Au sens de la présente invention, le taux d'élongation à la rupture et le taux de recouvrance sont évalués aux moyens des essais décrits ci-après.Within the meaning of the present invention, the rate of elongation at break and the recovery rate are evaluated by means of the tests described below.
Pour effectuer les essais de traction, le film est découpé en éprouvettes de forme rectangulaire, de longueur 80 mm et de largeur 15 mm.To carry out the tensile tests, the film is cut into test pieces of rectangular shape, length 80 mm and width 15 mm.
Les essais sont réalisés sur un appareil commercialisé sous l'appellation Lloyd ou commercialisé sous l'appellation Zwick dans les mêmes conditions de températures et d'humidité que pour le séchage, c'est-à-dire une température de 22 ± 2 °C et un taux d'humidité relative de 50 ± 5 %.The tests are carried out on a device marketed under the name Lloyd or marketed under the name Zwick under the same temperature conditions and humidity only for drying, i.e. a temperature of 22 ± 2 ° C and a relative humidity of 50 ± 5%.
Les éprouvettes sont étirées à la vitesse de 20mm/mn et la distance entre les mors est de 50 ± 1 mm.The test pieces are drawn at a speed of 20mm / min and the distance between the jaws is 50 ± 1 mm.
Pour déterminer la recouvrance instantanée (R;), on procède comme suit:To determine the instant recovery (R;), proceed as follows:
- on étire l'éprouvette de 150 % (εmax) c'est-à-dire 1,5 fois sa longueur initiale (I0) - on relâche la contrainte en imposant une vitesse de retour égale à la vitesse de traction, soit 20mm/mn et on mesure l'allongement de l'éprouvette en pourcentage , après retour à charge nulle (ε;).- the specimen is stretched by 150% (ε max ), that is to say 1.5 times its initial length (I 0 ) - the stress is relaxed by imposing a return speed equal to the traction speed, ie 20mm / min and the elongation of the test piece is measured as a percentage, after return to zero load (ε;).
La recouvrance instantanée en % (R;) est donnée par la formule ci-après:The instant recovery in% (R ; ) is given by the formula below:
Ri = ((εmax - ε;)/ εmax) x 100Ri = ((εmax - ε ; ) / ε max ) x 100
Pour déterminer la recouvrance à 300 secondes, on maintient à contrainte nulle pendant 300 secondes supplémentaires, l'éprouvette ayant subi les opérations précédentes, et on mesure son taux d'allongement en pourcentage (ε30o).To determine the recovery at 300 seconds, the specimen having undergone the preceding operations is maintained at zero stress for an additional 300 seconds, and its percentage elongation rate is measured (ε 30 o).
La recouvrance à 300 secondes en % (R3oo) est donnée par la formule ci-après:The recovery at 300 seconds in% (R 3 oo) is given by the formula below:
R300 = ((εma - ε3oo)/ εmax) x 100R300 = ((εma - ε 3 oo) / ε max ) x 100
Pour mesurer le module d'Young ou élasticité, on utilise une éprouvette ayant les dimensions précédentes. De préférence, le module d'Young est supérieur à 15 MPa.To measure the Young's modulus or elasticity, a test tube having the preceding dimensions is used. Preferably, the Young's modulus is greater than 15 MPa.
