| Résumé : |
The increasing demand for reliable broad-pectrum UVB and UVA protection has led to the development of various new sunscreen actives. The traditional classification divides sunscreen actives into organic (soluble) filters, such as a) EHMC, b) OCR, c) BMDBM, d) BEMT, etc, which only absorb UV radiation, and inorganic (insoluble) UV filters, such as TiO2 and ZnO which scatter, reflect and absorb the UV radiation. Now, a new class of organic (insoluble) UV absorbers is emerging: Microfine organic particles dispersed in water. Two candidates of this new class of UV absorbers will be discussed: e) MBBT, which is a broadband UVA1 absorber and a new triazine based compound, which is a research sample having UVB/UVA2 absorption. Both particule UV absorbers show pigment properties, which are close to TiO2 or ZnO, but also the typical high UV absorbance of organic UV filters. |
