The invention relates to a photostable sunscreen composition that not only provides enhanced sun protection by way of high SPF, but does that over sustained period of time after applying the composition on the skin. The present inventors have found that when a compound of the triazine group is used without additional UVA or UVB sunscreen, and a non-ionic surfactant is included in a cosmetic base comprising fatty acids, it is possible to achieve high SPF.

Photostable sunscreen composition

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.
