Abstract
A composition may include a base or matrix material, such as a resin, and a first optical brightener. The first optical brightener may include an alkaline earth metal compound and a fluorescence activator. The composition may include less than or equal to about 1.5 wt % of a second optical brightener relative to the weight of the composition, wherein the second optical brightener does not include the fluorescence activator. A composition may include an aqueous base and an optical brightener. The optical brightener may include an alkaline earth metal carbonate and a fluorescence activator, wherein the optical brightener is configured to emit fluorescent light. A composition may include a first optical brightener. The first optical brightener may include an alkaline earth compound, such as an alkaline earth metal salt, and a fluorescence activator, wherein, for a given brightness of a product including the composition, the composition including the first optical brightener may include less of a second optical brightener different from the first optical brightener.
