Abstract
A method of increasing the absorbance of ultraviolet light by sunscreen active compounds which are applied to a surface to protect the surface from excessive exposure to sunlight. A mixture is formed which includes at least one sunscreen active compound and an effective amount of a phenyl functional siloxane. The mixture is applied to the surface to be protected from excessive exposure to sunlight, and the surface including the mixture of the sunscreen active compound and the phenyl functional siloxane is exposed to light in the ultraviolet spectrum. A composition having increased absorbance of ultraviolet light for applying to a surface to protect the surface from excessive exposure to sunlight is also disclosed.
