A recently granted patent (Publication Number: US11883516B2) discloses a personal cleansing composition designed to enhance the deposition of sunscreens on the body's surface. The composition includes specific percentages of water-soluble UVA and UVB sunscreens, surfactants, and a cosmetically acceptable carrier. The UVA sunscreen options include di sodium phenyl dibenzimidazole tetra sulfonate and terephthalylidene dicamphor sulfonic acid, while the UVB sunscreen options consist of phenyl benzimidazole sulphonic acid, benzylidene camphor sulfonic acid, and benzophenone-4. Importantly, both sunscreens must have a solubility in water higher than 10 g/L at 25°C for optimal effectiveness.
Furthermore, the patent claims detail additional features such as the inclusion of a neutralizing agent in the composition, the percentage range of surfactants, and the method of using the composition to provide an improved sun protection factor on the body's surface. The method involves washing the surface with the personal cleansing composition and then rinsing it with water to achieve a sun protection factor of at least 8. The composition can be diluted with water for application and is specifically designed as a rinse-off product, emphasizing its practical and user-friendly nature for daily use.
