| titleOfInvention | Method for topical protection against atmospheric pollutant molecules and/or free radicals produced by exposure to ultraviolet radiation |
| abstract | A method of providing topical protection against atmospheric pollutant molecules and against ultraviolet (UV) radiation, said method comprising the steps of:n a) forming a polymer matrix that is both repellent and antiadhesive to atmospheric pollutant molecules, by means of a first biocompatible polymer (BP1); b) under the effect of UV radiation, photocatalytically degrading the pollutant molecules that have penetrated into the polymer matrix by means of first semiconductor colloids (Col-1) grafted covalently with a second biocompatible polymer (BP2), thereby leading to formation of free radicals; c) neutralizing said free radicals by means of at least 2 antioxidants, namely:n a first antioxidant in the form of second semiconductor colloids (Col-2) grafted covalently with said first antioxidant (AntiOx-1); the second grafted colloids (Col-2) self-regenerating under the action of the UV radiation; and a second antioxidant (AntiOx-2) that is not in the form of colloids grafted with an antioxidant; and n d) stabilizing the polymer matrix by means of the second antioxidant (AntiOx-2). |
