Description

émulsion écran solaire comprenant un mélange d’émulsifiants de siliconesunscreen emulsion comprising a mixture of silicone emulsifiers

DOMAINE DE L’INVENTIONFIELD OF THE INVENTION

La présente invention concerne des compositions cosmétiques et en particulier des émulsions d’écran solaire incluant un mélange d’émulsifiants de silicone.
discussion du contexteThe present invention relates to cosmetic compositions and in particular to sunscreen emulsions comprising a mixture of silicone emulsifiers.
discussion of context

Des compositions cosmétiques contenant des pigments afin d’apporter un pouvoir couvrant et une couleur, telles que celles convenables pour le maquillage du visage sont connues. Des compositions cosmétiques incluant divers émulsifiants sont également connues. Cependant, les compositions contenant à la fois des pigments et des niveaux élevés de filtres UV organiques sont difficiles à formuler. Les inventeurs ont reconnu qu’un des problèmes de la formulation de telles compositions est que l’incorporation de niveaux relativement élevés de pigments et de niveaux élevés de filtres UV organiques implique que les niveaux de pigments et de filtres UV organiques nécessaires pour fournir divers bénéfices à l’utilisateur contribuent à l’instabilité de la composition.Cosmetic compositions containing pigments in order to provide covering power and color, such as those suitable for facial makeup are known. Cosmetic compositions including various emulsifiers are also known. However, compositions containing both pigments and high levels of organic UV filters are difficult to formulate. The inventors have recognized that one of the problems with formulating such compositions is that the incorporation of relatively high levels of pigments and high levels of organic UV filters means that the levels of pigments and organic UV filters necessary to provide various benefits to the user contribute to the instability of the composition.

En conséquence, certains aspects de la présente invention concernent des compositions qui sont stables et ont une esthétique agréable, peuvent fournir une protection solaire et peuvent également fournir une couleur (teinte), un pouvoir couvrant, et/ou d’autres bénéfices.Accordingly, certain aspects of the present invention relate to compositions which are stable and aesthetically pleasing, may provide sun protection, and may also provide color (tint), hiding power, and/or other benefits.

Selon un aspect de l’invention, la présente invention concerne des compositions d’émulsion écran solaire eau dans l’huile qui incluent une phase aqueuse émulsifiée dans une phase grasse externe. La phase grasse externe inclut au moins environ 10 % en poids de filtres UV organiques par rapport à la composition entière. La phase grasse externe inclut également au moins un matériau gras de silicone. La composition inclut en outre un élastomère de silicone émulsifiant et un tensioactif de silicone non élastomère. La composition inclut en outre une argile gonflante et un pigment.According to one aspect of the invention, the present invention relates to water-in-oil sunscreen emulsion compositions which include an emulsified aqueous phase in an external fatty phase. The outer fatty phase includes at least about 10% by weight of organic UV screening agents relative to the entire composition. The outer fatty phase also includes at least one silicone fatty material. The composition further includes an emulsifying silicone elastomer and a non-elastomeric silicone surfactant. The composition further includes a swelling clay and a pigment.

Selon un autre aspect de l’invention, la présente invention concerne des procédés de traitement de la peau. Le procédé inclut l’application sur ladite peau d’une composition d’émulsion écran solaire eau dans l’huile qui inclut une phase aqueuse émulsifiée dans une phase grasse externe. La phase grasse externe inclut au moins environ 10 % en poids de filtres UV organiques par rapport à la composition entière. La phase grasse externe inclut également au moins un matériau gras de silicone. La composition inclut en outre un élastomère de silicone émulsifiant et un tensioactif de silicone non élastomère. La composition inclut en outre une argile gonflante et un pigment.According to another aspect of the invention, the present invention relates to methods of treating the skin. The method includes applying to said skin a water-in-oil sunscreen emulsion composition that includes an aqueous phase emulsified in an outer oily phase. The outer fatty phase includes at least about 10% by weight of organic UV screening agents relative to the entire composition. The outer fatty phase also includes at least one silicone fatty material. The composition further includes an emulsifying silicone elastomer and a non-elastomeric silicone surfactant. The composition further includes a swelling clay and a pigment.

Dans certains modes de réalisation, il est souhaitable que les un ou plusieurs filtres UV organiques soient choisis dans le groupe comprenant, incluant ou consistant en : homosalate, salicylate d’éthylhexyle et octocrylène.In certain embodiments, it is desirable that the one or more organic UV filters be selected from the group comprising, including or consisting of: homosalate, ethylhexyl salicylate and octocrylene.

Dans d’autres modes de réalisation, la composition est sensiblement exempte d’un, de plusieurs ou de tous les éléments suivants : avobenzone, oxybenzone, octylméthyoxycinnamate, écrans solaires inorganiques et huiles de silicone volatiles.In other embodiments, the composition is substantially free of one, more or all of the following: avobenzone, oxybenzone, octylmethyloxycinnamate, inorganic sunscreens and volatile silicone oils.

Il est entendu que tant la description générale qui précède que la description détaillée qui suit ne sont qu’exemplaires et explicatives et ne sont pas restrictives de l’invention.It is understood that both the general description which precedes and the detailed description which follows are only exemplary and explanatory and are not restrictive of the invention.
