Résumé : |
Recently, there has been growing interest in sunscreen performance. This interest includes not only making more efficient formulations but also more effective formulations. There are many factors that need to be considered when determining the efficiency of sunscreen formulations, including : desired SPF, UVA/UVB coverage, wavelength shift, and photostability, just to name a few.
The quest for complete protection from the sun has led to numerous research efforts that are aimed not only effective sunscreens, but also products that efficiently use sunscreens, minimising the concentration of filters. A product that protects over a wide variety of ultraviolet (UV) spectrum and is effective has become a priority. This quest has led to a new series of amphiphilic polymers that have been developed to help improve the efficiency of sunscreens. These amphiphilic polymers have a polar core surrounded by a fatty oil soluble group. This series of polymers can provide not only a shift in wavelength, but also boost the SPF of the sunscreen formulation. These new polymers have been coinde 'Spider esters'. |
