An optimized sun protection product must deliver broad spectrum UV blocking to protect skin against erythema, premature aging and photocarcinogenesis. Such broad UV spectrum protection is afforded using a combination of organic and inorganic UV filters in accordance with the FDA sunscreen monograph or equivalent regulations within different countries.  The SPF rating is a measurement of protection against sunburn, that is, it conveys how well a product shields skin from UVB radiation. 

Use of silicones in sun protection products continues to grow as they offer superior esthetic and technical characteristics. They deliver refined sensory benefits such as lightness, softness, a luxurious texture, longer-lasting and protecting effects.  In addition, a host of functional silicones, including elastomers, resins, alkyl modified siloxanes and silicone emulsifiers offer unique formulating advantages.
