Title (EN) SUNSCREEN COMPOSITION
(FR) PRODUIT ANTISOLAIRE
Abstract:
(EN) The invention provides a sunscreen formulation including conventional UVB sunscreening agents and zinc oxide having an average particle size in the order of 150 to 800 nm. Preferably the zinc oxide used is pigment grade. Most preferably, zinc oxide prepared by the French process is used, although that produced by the American process is also suitable. The average particle size of the zinc oxide is most preferably in the order of 200-400 nm. Throughout this specification, the term 'pigment grade' is used to define zinc oxide that has been produced by the French or American process. A further embodiment of the invention is a method of reducing or preventing the harmful effects of solar radiation on skin by applying the inventive sunscreen formulation. A further embodiment of the invention relates to a sunscreen composition having a sun protection factor greater than 30 including zinc oxide having an average particle size of 150 to 800 nm. A still further embodiment of the invention relates to a sunscreen composition which is susbstantially transparent upon application to the skin including zinc oxide having an average particle size of 150 to 800 nm.
(FR) L'invention concerne une formulation antisolaire comprenant les agents antisolaires anti UVB et de l'oxyde de zinc ayant une dimension granulométrique moyenne de l'ordre de 150 à 800 nm. L'oxyde de zinc utilisé appartient, de préférence, à la classe des pigments. Idéalement, l'oxyde de zinc préparé selon le procédé français est utilisé, bien que celui produit par le procédé américain convienne également. La dimension granulométrique moyenne de l'oxyde de zinc est idéalement de l'ordre de 200 à 400 nm. Dans le contexte de l'invention, le terme 'classe des pigments' est utilisé pour définir de l'oxyde de zinc ayant été produit selon les procédés américain et français. Dans un autre mode de réalisation, l'invention se rapporte à un procédé de réduction des effets nocifs du rayonnement solaire sur la peau par l'application de la formulation antisolaire de l'invention. Dans un autre mode de réalisation, l'invention porte sur un produit antisolaire présentant un facteur de protection solaire supérieur à 30 et comprenant de l'oxyde de zinc ayant une dimension granulométrique moyenne de 150 à 800 nm. Dans encore un autre mode de réalisation, l'invention concerne un produit antisolaire qui est sensiblement transparent lorsqu'il est appliqué sur la peau, et qui contient de l'oxyde de zinc ayant une dimension granulométrique moyenne de 150 à 800 nm.
