The present invention relates to a powder formulation comprising at least one insect repellent and magnesium hydroxide carbonate, and to a process for the preparation of the formulation and to the use of the formulation for repelling insects.

Powder formulation containing insect repellent

The present invention relates to a process for treating sol-gel capsules comprising a cosmetic or pharmaceutical active material with an inorganic material, as well as sol-gel capsules produced by a process according to the present invention and formulations comprising such sol-gel capsules.

Process for treating sol-gel capsules

The invention relates to metal oxide particles and/or metal hydroxide particles, aftertreated with an organic phosphorus compound, process for the preparation thereof, and compositions comprising same.

Metal oxide particles aftertreated with organic phosphorus compounds

The present invention relates to nanoparticulate UV protectants which are obtainable by hydrothermal treatment of a nanoparticulate metal oxide and subsequent application of a silicon dioxide coating, and to the preparation and use thereof. The present invention furthermore relates to novel compositions, in particular for topical application, which are intended, in particular, for light protection of the skin and/or of the hair against UV radiation, and to the use thereof in the above-mentioned cosmetic application.

Nanoparticulate UV protectant with silicon dioxide coating

The present invention relates to particulate UV protection agents which are obtainable by hydrothermal treatment of a particulate metal oxide and subsequent application of a manganese oxide coating, and to the preparation and use thereof. The present invention furthermore relates to novel compositions, in particular for topical application, which are intended, in particular, for light protection of the skin and/or hair against UV radiation and free-radical-induced stress, and to the use thereof in the above-mentioned cosmetic application.

Particulate UV protection agent

The invention relates to compounds of the formula (I) or (II), to compositions which comprise such compounds, to corresponding processes for the preparation of the compounds or the compositions comprising same, and to the use thereof as light-protection filters. 

UV filters

The invention relates to compounds of the formula I where R, R, R, Rand Rhave the meanings given in claim 1. The compound is suitable in particular for use in skin care compositions. They protect, firstly, against harmful oxidation reactions and, secondly, also act as UV filters.

Galenical formulation

The invention relates to the use of quinoxaline derivatives of formula I, represented by formulas 1and 1, as photostable UV filters, in particular in cosmetic and pharmaceutical preparations for protecting the human epidermis or human hair against UV radiation, above all in the 280&#x2013;400 nm range. 

Tricyclic quinoxaline and quinoline derivatives as a UV filter
