Compositions comprising UV blocking agents, a film forming polymer containing acid groups and a neutralizing agent; compositions and methods for increasing the SPF of a composition by neutralizing at least a portion of the acid groups of the film forming agent with the neutralizing agent.

Enhanced efficiency of sunscreen compositions

Antioxidant-containing compositions and methods for confirming antioxidant activity of a composition formulated for topical application to skin. Methods for testing a composition for ability to inhibit both ultraviolet radiation-induced lipid peroxidation on skin and ultraviolet radiation-induced reactive oxygen species formation in the stratum corneum. Compositions and methods for treating and preventing photodamage to skin.

Method of selecting antioxidants for use in topically applied compositions

Certain aspects of the invention relate to compositions comprising UV blocking agents, a film forming polymer containing acid groups and a neutralizing agent. Such compositions have an increased SPF due to neutralization of at least a portion of the acid groups of the film forming agent by the neutralizing agent. The invention also discloses methods for increasing SPF of a composition as well as methods for using the novel composition.

The invention provides antioxidant-containing compositions and methods for confirming antioxidant activity of a composition formulated for topical application to skin. The invention also provides methods for testing a composition for the ability to inhibit both ultraviolet radiation-induced lipid peroxidation on skin and ultraviolet radiation-induced reactive oxygen species formation in the stratum corneum as well as compositions and methods for treating and preventing photodamage to skin.

Methods and compositions useful in enhancing protection from UV radiation, the compositions containing octyl triazone and diethylthexyl syringylidene malonate in an amount effective to photostabilize octyl triazone.

Photostabilization of octyl triazone

Sunscreen compositions contain the active ingredients avobenzone, zinc oxide and phenylbenzimidazole sulfonic acid. The phenylbenzimidazole sulfonic acid protects avobenzone against photodegradation.

Stabilized photoprotective composition

A formulation for topical application, the formulation comprising a waterborne polyurethane polymer; a thickening agent; a humectant, at least one sunscreen active agent, and an emulsifying agent.

Sunscreen formulations containing waterborne polyurethane polymers

A colored sunscreen emulsion which enables the user to more effectively protect against skin damage, by facilitating more complete and uniform coverage of the sunscreen on the skin, comprises:
