Composition d’écran solaire cosmétique, utilisation d’une composition d’écran solaire cosmétique, et processus de fabrication d’une composition d’écran solaire cosmétiqueCosmetic sunscreen composition, use of cosmetic sunscreen composition, and process for making cosmetic sunscreen composition

DOMAINE DE L’INVENTIONFIELD OF THE INVENTION

La présente invention concerne une nouvelle composition d’écran solaire cosmétique comprenant (a) un silylate de silice ; (b) un agent suspenseur choisi parmi l’acide polyhydroxystéarique, ou un mélange d’acide polyhydroxystéarique et de diéthylhexanoate de néopentylglycol, et (c) au moins un filtre UV. La présente invention concerne également l’utilisation d’une composition d’écran solaire cosmétique, et un processus de fabrication d’une composition d’écran solaire cosmétique.The present invention relates to a novel cosmetic sunscreen composition comprising (a) a silica silylate; (b) a suspending agent chosen from polyhydroxystearic acid, or a mixture of polyhydroxystearic acid and neopentylglycol diethylhexanoate, and (c) at least one UV filter. The present invention also relates to the use of a cosmetic sunscreen composition, and a process for manufacturing a cosmetic sunscreen composition.

contexte de l’inventionbackground of the invention

La photoprotection des matières kératineuses, incluant à la fois la peau et les cheveux, est considérée comme très importante afin de les protéger contre les dommages causés par le soleil, les coups de soleil, le photovieillissement, ainsi que pour diminuer les risques de développement de cancers de la peau causés par l’exposition aux rayons ultraviolets (« UV »). Il existe typiquement deux types de compositions d’écran solaire cosmétiques UVA/UVB utilisées pour assurer une photoprotection, à savoir les filtres UV inorganiques et les filtres UV organiques.The photoprotection of keratinous materials, including both skin and hair, is considered very important in order to protect them against damage caused by the sun, sunburn, photoaging, as well as to reduce the risk of development of skin cancers caused by exposure to ultraviolet (“UV”) rays. There are typically two types of UVA/UVB cosmetic sunscreen compositions used to provide photoprotection, namely inorganic UV filters and organic UV filters.

Le degré de protection UV offert par une composition d’écran solaire cosmétique est directement lié à la quantité et au type de filtres UV qu’elle contient. En particulier, les compositions d’écran solaire cosmétiques doivent fournir une bonne protection contre les rayons du soleil, dont une mesure est la valeur de l’indice de protection (IP), un équilibre souhaitable entre la protection UVA et UVB, en particulier un indice de protection UVA minimum, tout en ayant une perception sensorielle satisfaisante, telle qu’une sensation lisse mais non grasse à l’application.The degree of UV protection offered by a cosmetic sunscreen composition is directly related to the amount and type of UV filters it contains. In particular, cosmetic sunscreen compositions should provide good protection against the sun's rays, one measure of which is the protection factor (SPI) value, a desirable balance between UVA and UVB protection, in particular a minimum UVA protection index, while having a satisfactory sensory perception, such as a smooth but non-greasy feeling on application.

Cependant, cette combinaison de propriétés est difficile à obtenir, notamment parce que de nombreux composés actifs solaires ont eux-mêmes une sensation huileuse ou grasse, et que l’augmentation de leur teneur tend à provoquer le même effet chez le produit final.However, this combination of properties is difficult to achieve, not least because many sunscreen active compounds have an oily or greasy feel themselves, and increasing their content tends to cause the same effect in the final product.

En outre, la plupart des filtres solaires organiques sont des matériaux huileux et/ou solubles dans l’huile. Des niveaux élevés de filtres solaires dans les produits solaires rendent les produits moins attrayants en raison de leur sensation de peau grasse, de leur caractère collant et de leur long temps de séchage.Also, most organic sunscreens are oily and/or oil-soluble materials. High levels of sun filters in sunscreen products make the products less appealing due to their oily skin feel, stickiness and long drying time.

Dans ce sens, un ingrédient cosmétique utilisé pour aider à contrôler le caractère gras de la matière kératineuse après l’application de la composition d’écran solaire cosmétique, et pour fournir un effet mat, est le silylate de silice.In this sense, a cosmetic ingredient used to help control the oiliness of the keratinous material after the application of the cosmetic sunscreen composition, and to provide a matte effect, is silica silylate.

Néanmoins, un problème supplémentaire des compositions d’écran solaire cosmétiques avec cet ingrédient est que de fortes concentrations de silylate de silice ont tendance à se repousser et à s’agglomérer dans les émulsions, en particulier dans les émulsions huile dans l’eau en raison de la présence d’eau sur la phase externe, ce qui entraîne une composition d’écran solaire cosmétique instable.However, an additional problem with cosmetic sunscreen compositions with this ingredient is that high concentrations of silica silylate tend to repel and clump together in emulsions, especially in oil-in-water emulsions due to the presence of water on the external phase, which leads to an unstable cosmetic sunscreen composition.

Par conséquent, il existe un besoin pour de nouvelles compositions d’écran solaire cosmétiques avec un IP élevé et une quantité plus élevée de silylate de silice, qui ne sont pas lourdes sur la peau et qui sont capables de contrôler la teneur en huile de la peau après leur application, laissant la peau avec une finition mate, qui est stable.Therefore, there is a need for new cosmetic sunscreen compositions with a high SPF and a higher amount of silica silylate, which are not heavy on the skin and which are able to control the oil content of the skin. skin after their application, leaving the skin with a matte finish, which is stable.

Cela dit, l’objectif de la présente invention est de fournir une composition d’écran solaire cosmétique stable avec des quantités plus élevées de silylate de silice dans une émulsion, en particulier une émulsion huile-dans-eau.That said, the object of the present invention is to provide a stable cosmetic sunscreen composition with higher amounts of silica silylate in an emulsion, particularly an oil-in-water emulsion.

Les inventeurs de la présente demande ont réussi de manière étonnante à développer une telle nouvelle composition d’écran solaire cosmétique en utilisant un agent suspenseur choisi parmi l’acide polyhydroxystéarique, ou un mélange d’acide polyhydroxystéarique et de diéthylhexanoate de néopentylglycol.The inventors of the present application have surprisingly succeeded in developing such a new cosmetic sunscreen composition using a suspending agent chosen from polyhydroxystearic acid, or a mixture of polyhydroxystearic acid and neopentylglycol diethylhexanoate.

La présente invention concerne de nouvelles compositions d’écran solaire cosmétiques comprenant (a) un silylate de silice ; (b) un agent suspenseur choisi parmi l’acide polyhydroxystéarique, ou un mélange d’acide polyhydroxystéarique et de diéthylhexanoate de néopentylglycol ; et (c) au moins un filtre UV. La présente invention concerne également l’utilisation d’une composition d’écran solaire cosmétique, et un processus de fabrication d’une composition d’écran solaire cosmétique.The present invention relates to novel cosmetic sunscreen compositions comprising (a) a silica silylate; (b) a suspending agent selected from polyhydroxystearic acid, or a mixture of polyhydroxystearic acid and neopentylglycol diethylhexanoate; and (c) at least one UV filter. The present invention also relates to the use of a cosmetic sunscreen composition, and a process for manufacturing a cosmetic sunscreen composition.
