Abstract: Disclosed herein are oil-in-water dispersions and sunscreen compositions that contain them, which exhibit high in vivo sun protection factor (SPF) efficiency due to the ability of the dispersions to both absorb and scatter ultraviolet (UV) light. These high efficiency sunscreen compositions include discrete oil particles that are enclosed within a solid coating and dispersed in an aqueous phase, wherein each oil particle contains an organic ultraviolet A (UVA) and/or an organic ultraviolet B (UVB) absorbing compound, and optionally a photostabilizer.

Abstract: Comparative effectiveness of various oral care products such as dentifrices on preventing dental erosion may be demonstrated using simulated enamel A substrate is prepared. A mineral layer to simulate dental enamel is nucleated by solution growth on the substrate surface. Alternatively, the mineral layer may be nucleated on a template comprising a self-assembled monolayer formed on a gold layer deposited on the substrate surface. The mineral layer may comprise a homogeneous layer of hydroxyapatite or a thin veneer of hydroxyapatite on a layer of amorphous calcium phosphate. The simulated enamel is then optionally treated with an oral care product and subjected to an acid challenge. The amount of mineral layer remaining after the acid challenge illustrates the effectiveness or non-effectiveness of the oral care product at preventing dental erosion.

Abstract: Disclosed are oral care compositions comprising selected surface-active organophosphate compounds and methods of use to provide protection of teeth from erosion caused by the action of chemicals, such as harsh abrasives and acids. The surface-active organophosphate compounds are substantive to teeth, the phosphate groups binding the calcium in teeth and thus preventing loss of calcium from dissolution when contacted with acids. The organophosphate compound may also deposit a protective surface coating that prevents contact of teeth with erosive challenges.
