| abstract |
The present application relates to a composition which includes water-soluble 1,3-diketone sunscreens, more particularly, water-soluble dibenzoylmethane sunscreens, where the sunscreens exhibit relatively low photodegradation; and a method for reducing the photodegradation of the water-soluble 1,3-diketone sunscreens. It is an object of the present application to provide a composition, which includes a water-soluble 1,3-diketone sunscreen, where the photodegradation of 1,3-diketone sunscreen is relatively low. The present inventors have found that water-soluble dibenzoylmethanes too suffer from the problem of photodegradation. It has been found that use of conventional stabilizers do not provide adequate stability. It has also been found that the stability of water-soluble 1,3-diketones is affected in the presence of conventional emulsifiers/surfactants, which are often included in cosmetic compositions. |
