The present invention is a water-in-oil emulsion having a high content of water and relatively high amounts of skin-moisturizing agents and a cosmetic or dermatological stick including the water-in-oil emulsion. The present invention also includes methods of moisturizing the skin using the water-in-oil emulsion. The water-in-oil emulsion is solid at room temperature and comprises a fatty phase with at least one oil component and at least one wax component, an aqueous phase with a skin-moisturizing agent in addition to water, a water-in-oil emulsifier having the general structure A-B-A', where A&#x2032; and A&#x2032; represent the same or different hydrophobic inorganic groups and B is a hydrophilic group.

Cosmetic or dermatological stick

The invention is a light-protective cosmetic or dermatological preparation, comprising (a) at least hydroxybenzophenone and (b) at least one benzoxazole derivative. The invention is also a cosmetic or dermatological preparation comprising at least one hydroxybenzophenone of a specified chemical structure and at least one benzoxazole derivative. The invention is also a method of treating or preventing cosmetic or dermatological changes in the skin, a method of tanning or accelerating tanning of the skin, and a method of protecting the skin against light-induced aging, each comprising applying the preparation to the skin. The invention also includes a wipe impregnated with the preparation.

Cosmetic or dermatological light-protective formulation comprising a hydroxybenzophenone and a benzoxazole derivative

The cosmetic or dermatological formulations of the invention include: in which Rand R, independently of one another, are chosen from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms, and

Stabilization of oxidation-sensitive or UV-sensitive active ingredients

Cosmetic and dermatological formulations comprising at least one hydrophilic active ingredient and at least one dialkyl naphthalate which is characterized by the structural formula in which Rand R, independently of one another, are selected from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms, have been found to be stable and effective, particularly in moisturizing the skin or protection the skin from skin aging.

Stablization of oxidation-sensitive or UV-sensitive active ingredients

The invention relates to light-protective cosmetic or dermatological preparations that contain (a) at least one hydroxy-benzophenone, and (b) at last one dialkyl naphthalate of the structural formula (I), wherein Rand Rare independently selected form the group of the branched and unbranched alkyl groups that have 6 to 24 carbon atoms. The invention further relates to the use of said formulations 

Cosmetic and dermatological light protection formulations with a content of hydroxybenzophenones and alkylnaphthalates

Cosmetic or dermatological formulations comprising at least one particulate UV filter substance and at least one dialkyl naphthalate having the structural formula wherein Rand Rare selected independently of one another from the group consisting of branched and unbranched alkyl groups having 6 to 24 carbon atoms, are useful for protecting skin from harmful effects of solar radiation, particularly from UV-A and UV-B radiation.

Cosmetic and dermatological light-protective formulations with a content of particulate UV-filter substances and alkylnaphthalates

The invention is a cosmetic or dermatological formulation, comprising: in which Rand R, independently of one another, are chosen from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms; and

Cosmetic and dermatological formulations containing at least one UV-sensitive active ingredient have increased UV protection and have the active ingredient stabilized against decomposition through addition of at least one dialkyl naphthalate of the structural formula wherein Rand Rare selected independently of one another from the group consisting of branched and unbranched alkyl groups having between 6 and 24 carbon atoms, and at least one emulsifier, selected from the group consisting of phosphate and sulphate emulsifiers.

Stabilization of UV-sensitive active ingredients

The invention is a light-protective cosmetic or dermatological preparation comprising (a) at least one water-soluble UV-filter substance and (b) at least one benzoxazole derivative. The invention is also a cosmetic or dermatological preparation comprising at least one water-soluble UV-filter substance and at least one benzoxazole derivative of a specified chemical structure. The invention is also a method of treating or preventing cosmetic or dermatological changes in the skin, a method of tanning or accelerating tanning of the skin, and a method of protecting the skin against light-induced aging, each comprising applying the cosmetic or dermatological preparation to the skin. The invention also includes a wipe impregnated with the preparation.

Cosmetic or dermatological light-protective formulation comprising a water-soluble UV filter substance and a benzoxazole derivative

The invention is a light-protective cosmetic or dermatological preparation, comprising (a) at least benzotriazole and (b) at least one benzoxazole derivative. The invention is also a cosmetic or dermatological preparation comprising at least one benzotriazole from a select group and at least one benzoxazole derivative of a specified chemical structure. The invention is also a method of treating or preventing cosmetic or dermatological changes in the skin, a method of tanning or accelerating tanning of the skin, and a method of protecting the skin against light-induced aging, each comprising applying the preparation to the skin. The invention also includes a wipe impregnated with the preparation.
