  PRODUIT DE PROTECTION CONTRE LA LUMIERE. 



   Depuis que l'on sait que l'on peut obtenir une coloration ou pig- mentation également sans produire des rougeurs de la peau, on s'est efforcé d'utiliser des produits de protection contre la lumière qui satisfont à cette condition et qui ne laissent donc pas passer principalement que la gam- me à ondes courtes de la lumière ultra-violette du soleil de nature à affec- ter la peau, mais qui peuvent être aussi perméables que possible à la gamme d'ondes plus.longues de ce rayonnement, dans laquelle on obtient encore un bon brunissement. 



   La présente invention a pour objet un produit de protection con- tre la lumière, qui est constitué par un mélange contenant les sulfonamides ou leurs sels solubles, ce mélange arrêtant la gamme à ondes très courtes de la lumière ultra-violette par absorption, diffraction et réflexion. 



   Or, cette action n'est pas basée seulement sur des essais opti- ques, mais également sur des essais biologiques, par lesquels on a pu prou- ver que l'on peut obtenir avec le produit conforme à l'invention un arrêt du rayonnement allant   jusqu'à:   dix doses d'érythème, alors qu'avec les pro- duits connus jusqu'à présent, on ne pouvait obtenir environ que trois doses. 



   Pour le nouveau produit de protection contre la lumière, on prend en considération comme sulfonamides en particulier des corps de la formule générale NH2-C6H4-SO2< R, dans laquelle R indique un reste organique. Pour cela, il y a encore lieu de citer en particulier comme exemples les matières sodium-sulfamide-thiasol et sodium-sulfamide-pyridine, ainsi que leurs sels solubles. 



   L'utilisation de ce nouveau produit peut se faire de diverses ma- ni.ères. Comme produit de protection de la peau, il peut être utilisé, par 

 <Desc/Clms Page number 2> 

   exemple,  avec avantage solution claire, particulier solution aqueu- se, desorte qu'il produit, lorsqu'il est appliqué sur la peau une mince en- veloppe cristalline invisible, qui arrête le rayonnement indésirable par ab- sorption, diffraction ou réflexion et élimine en tout cas son action nuisi- ble. Mais, on peut aussi utiliser en outre une solution alcoolique ou autre solution appropriée du produit. Enfin, le sulfonamide peut être contenu dis- sous dans une substance de forme consistante pouvant être étendue, le produit pouvant, par exemple, être appliqué à la manière d'une crème ou d'un beaume. 



  On peut aussi utiliser comme véhicule ou produit de support des substances de nature grasse ayant un bon pouvoir adhésif. 



   L'invention est applicable pour les usages les plus divers. Elle a une importance toute particulière pour la protection de la peau. Mais elle peut en outre être utilisée également comme collyre, dont des gouttes sont mises dans les yeux avant d'assister à la projection de films ou de procéder à des travaux de soudure. Le nouveau produit de protection peut être établi de telle manière qu'il sèche sous une couche pelliculaire continue tout-à- fait invisible, qui n'est aucunement sentie par la personne qui la porte. 



  En choisissant des sulfonamides convenables, non seulement cette couche peut être absolument non irritante, mais elle peut également être bactéricide dans une grande mesure, car on sait que certaines sulfonamides ont cette propriété. Mélangé avec un colorant convenable, le produit peut être utili- sé comme rouge à lèvre adhérent fermement qui protège en même temps contre les gerçures des lèvres. 



   D'autres applications, du produit de l'invention sont, par exem- ple, le traitement d'étoffes ou d'autres matières sensibles à la lumière pour les rendre solides à la lumière, l'obtention dune protection de vitrines   (ce   qui' évite l'emploi de filtres jaunes) et de nombreuses autres applications.

  LIGHT PROTECTION PRODUCT.



   Since it has been known that coloring or pigmentation can also be obtained without producing redness of the skin, attempts have been made to use light protection products which satisfy this condition and which do not. therefore not mainly only allow the short-wave range of ultraviolet light from the sun to pass through, which may affect the skin, but which may be as permeable as possible to the longer-wave range of this radiation. , in which a good browning is still obtained.



   The present invention relates to a product for protection against light, which consists of a mixture containing sulfonamides or their soluble salts, this mixture stopping the very short-wave range of ultraviolet light by absorption, diffraction and reflection.



   However, this action is not based only on optical tests, but also on biological tests, by which it has been possible to prove that it is possible to obtain with the product in accordance with the invention a stop of the radiation. up to ten doses of erythema, whereas with the products known heretofore only about three doses could be obtained.



   For the new light shielding product, particular sulfonamides are suitable substances of the general formula NH2-C6H4-SO2 <R, in which R denotes an organic residue. For this, it is also necessary to mention in particular as examples sodium-sulfonylurea-thiasol and sodium-sulfonamide-pyridine, as well as their soluble salts.



   The use of this new product can be done in various ways. As a skin protection product, it can be used, for

 <Desc / Clms Page number 2>

   example, with advantage clear solution, especially aqueous solution, so that it produces, when applied to the skin a thin invisible crystalline envelope, which stops unwanted radiation by absorption, diffraction or reflection and eliminates in any case its harmful action. However, it is also possible to additionally use an alcoholic solution or other suitable solution of the product. Finally, the sulfonamide may be contained dissolved in a substance of consistent expandable form, the product may, for example, be applied in the manner of a cream or a balm.



  Substances of a fatty nature having good adhesive power can also be used as vehicle or support product.



   The invention is applicable for the most diverse uses. It is of particular importance for the protection of the skin. But it can also be used also as eye drops, drops of which are put in the eyes before attending the projection of films or carrying out welding work. The new protective product can be made in such a way that it dries under a continuous, completely invisible film layer, which is not felt by the wearer.



  By choosing suitable sulfonamides, not only can this layer be absolutely non-irritating, but it can also be bactericidal to a great extent, since some sulfonamides are known to have this property. Mixed with a suitable colourant, the product can be used as a tightly adherent lipstick which at the same time protects against chapped lips.



   Other applications of the product of the invention are, for example, the treatment of fabrics or other light-sensitive materials to make them lightfast, obtaining protection of shop windows (which 'avoids the use of yellow filters) and many other applications.
