Definitions

  • the present invention relates to a photoprotective composition based on the association of at least one organic UV filter, spherical composite particles, boron nitride particles and spherical porous silica particles. More particularly, the present invention relates to a cosmetic composition which achieves both high SPF PPD values and good usability.
  • UV-B radiation It is known that light radiation with wavelengths of between 280 nm and 400 nm permits tanning of the human epidermis and that light rays with wavelengths more particularly between 280 and 320 nm, known as UV-B rays, cause skin burns and erythema which can harm the development of a natural tan. For these reasons, and also for aesthetic reasons, there is constant demand for means for controlling this natural tanning in order thus to control the colour of the skin; this UV-B radiation should thus be screened out.
  • UV-A rays with wavelengths between 320 and 400 nm, which cause tanning of the skin, are liable to induce adverse changes therein, in particular in the case of sensitive skin or skin that is continually exposed to solar radiation.
  • UV-A rays cause in particular a loss of elasticity of the skin and the appearance of wrinkles leading to premature ageing of the skin.
  • anti-UV compositions containing organic UV filters that are active both in the UV-A range and in the UV-B range are generally used.
  • cosmetic products containing one or more inorganic and/or organic UV screening agents there are many cosmetic products containing one or more inorganic and/or organic UV screening agents.

  • JP 2004-323473A discloses to a cosmetic composition containing a white inorganic pigment with the mean particle diameter of from 0.12 to 1.0 ⁇ and a spherical complex polymer particle whose mean particle diameter is less than 5 ⁇ . It allegedly provides natural and transparent finish. But it does not teach UV protecting effect.

  • the above component was prepared with normal procedure for o/w emulsion containing powder.
  • the oily phase Al and the aqueous phase B were respectively prepared by mixing the raw materials, with mechanical stirring, at 80 degrees Centigrade. The obtained mixtures were macroscopically homogeneous.
  • the powder phase A2 was added into the oily phase Al .
  • the oily phase mixture (A1+A2) was slowly introduced into the aqueous phase B using a homogenizer at a stirring speed of 5000 rpm for 10 minutes at 65 degrees Centigrade.
  • To the obtained emulsion (A1+A2+B) was added the phase C using a homogenizer at a stirring speed of 5000 rpm for 10 minutes.
  • the obtained emulsion (A1+A2+B+C) was cooled to room temperature with stirring.
  • To the emulsion was added the phase D with stirring.
  • the obtained emulsion (A1+A2+B+C+D) was cooled to room temperature with gentle stirring, and thereto was added the phase E, to give the composition.
  • the composition according to Example 1 was an o/w cream-type emulsion.
  • the averaged score was graded on a four-point scale, according to the following criteria: Excellent: 5.0-4.0, Fair: 3.9-3.0, Not fair or poor: 2.9-2.0 and Poor: 1.9-1.0.
  • the sun protection factor (SPF) is expressed mathematically as the ratio of the irradiation time necessary to reach the erythema-forming threshold with the UV-screening agent (UV filter) to the time necessary to reach the erythema-forming threshold without UV-screening agent. It is evaluated in vivo especially according to the international method published by Colipa / CTFA SA / JCIA (May 2006). To characterize the protection with respect to UV-A, the PPD (persistent pigment darkening) method, which measures the skin color observed 2 to 4 hours after exposure of the skin to UV-A, is particularly recommended and used.

Abstract

La présente invention concerne une composition contenant dans un milieu cosmétiquement acceptable (A) au moins un filtre UV organique, (B) des particules composites sphériques ayant une taille moyenne de 1 à 20 µm, comprenant une matrice et un filtre UV inorganique, (C) des particules de nitrure de bore et (D) des particules sphériques de silice poreuse. La composition selon la présente invention présente un effet protecteur contre les UV important (tel que FPS et PPD élevés) et une plus grande aptitude à l'emploi telle qu'un aspect moins blanchâtre sur la peau et une consistance moins grasse. La présente invention concerne en outre un procédé cosmétique de soin et/ou maquillage des matériaux kératiniques qui consiste à appliquer sur la surface au moins un processus de composition pour le soin et/ou maquillage des matériaux kératiniques qui consiste à appliquer sur la surface au moins une composition telle que définie ci-dessus.
