Abstract: The invention relates to a high SPF sunscreen composition. There is a problem of achieving high SPF while keeping the total amount of sunscreens in the compositions relatively low. It is desirable, that the enhanced SPF benefit could be achieved through synergistic interaction of commonly used ingredients, thereby the present applicants have been working on solving this problem and have surprisingly found that cosmetic compositions comprising dibenzoylmethane or its derivative in combination with an oil soluble UV-B sunscreen when incorporated in a sunscreen composition along with a non-ionic surfactant of a select class meeting certain HLB requirements, provide the enhanced SPF benefits when applied on the substrate of interest.

Abstract: The invention relates to a high SPF/UVAPF sunscreen composition. It is an object of the present invention to provide a high SPF (equal to or greater than 15) or high UVAPF (equal to or higher than 4) photo-protective sunscreen composition without compromising on the desired skin sensorial properties while using relatively low amounts of sunscreen agents thereby keeping costs low.

Abstract: The present invention relates to photostable sunscreen compositions comprising sunscreens, more particularly to a liquid composition in emulsion or microemulsion format comprising dibenzoylmethane sunscreens. An object of the present invention is to provide photostable compositions comprising dibenzoylmethane sunscreens, wherein the stabilization is brought about by using readily available and inexpensive ingredients. The present inventors have surprisingly found that cosmetic compositions comprising dibenzoylmethane or its derivative can be stabilized in a specific liquid emulsion or microemulsion formulation having specified ingredients in selective amounts.
