The present invention relates to the use of self-tanning substances for application to the human skin, with application taking place at elevated temperature, to corresponding methods of application to the human skin and to a cosmetic formulation which is suitable for said purpose.

Method of tanning human body by mysting or immersion at elevated temperature

The invention relates to cosmetic formulations containing dihydroxy-acetone and a topical support in addition to one or several compounds selected from the compounds of formulae (Ia) and (Ib), the physiologically acceptable salts of compounds of formulae (Ia) and (Ib), and the stereoisomeric forms of formulae (Ia) and (Ib), wherein R, R, R, Rand n have the meanings cited in Claim. The cosmetic formulations are characterized in that the UV-A protective effect of dihydroxyacetone is increased. 

Cosmetic formulation comprising dihydroxyacetone

The invention relates to sun-protection formulations in solid or liquid form, containing organic and/or inorganic sunscreen filters having a prophylactic action against herpetic diseases of the skin, and to the use of said sun-screen formulations.

Sun-protection formulations active against herpes simplex viruses

The invention relates e.g. to the use of aldehydes and/or ketones for improving the stability of cosmetic formulations containing butylmethoxydibenzoylmethane as organic light protection filters in conjunction with inorganic light protection filters.

Stable cosmetic formulation containing butylmethoxydibenzoylmethane

A cosmetic preparation having butylmethoxydibenzoyhmethane as a protection filter and insoluble inorganic particles which are titanium dioxide particles doped with cerium or iron ions which absorb in the UVA region and are added to improve the photostability of the cosmetic preparation.

Light-stable cosmetic formulation containing butylmethoxydibenzoylmethane

The invention related to powder mixtures containing formaldehyde- and/or formic acid-releasing compounds which have skin-tanning properties, which powder mixtures contain an agent which forms sulphite ions and, if appropriate, a stabilizer, and to the preparation and use of these powder mixtures for manufacturing cosmetic or pharmaceutical preparations.

Skin-coloring powder mixture

The present invention relates to stable aqueous formulations of the insect repellent ethyl 3-(N-butyl-acetamino)propionate.

Stable aqueous formulation of 3-(N-butylacetamino)-propionic acid ethyl ester

The invention relates to novel light protection filters for the VIS and IR region for the preparation of sunscreens and also to the use thereof in cosmetics. The invention further relates to sunscreens which have broad-band or ultraspectral protection.

Sunscreens having ultraspectral protection

The present invention relates to a dispersion of inorganic UV filters in liquid UV filters and their use in sunscreens.

Dispersion of inorganic UV filters

The invention relates to powder mixtures containing formaldehyde- and/or formic acid-releasing compounds which have skin-tanning properties, which powder mixtures contain an agent which forms sulphite ions and, if appropriate, a stabilizer, and to the preparation and use of these powder mixtures for manufacturing cosmetic or pharmaceutical preparations.
