  • LIGHT PROTECTING COMPOSITION WITH REDUCED TOTAL AMOUNT OF UV FILTER CONTAINING A POLYSILOXANE-BASED UV FILTER
    Publication number: 20150174045
    Abstract: Light protecting compositions contain at least one polysiloxane-based UV filter. The composition has an increased ratio of the sunprotecting factor to the total UV filter amount. This is achieved by the combination with at least one UV filter which chromophore contains appropriate bulky (sterically demanding) substituents as steric protection groups.
