The present invention relates to a composition comprising a specific hyperbranched copolymer (HBC) of the monomers dodecenyl succinic acid anhydride, diisopropanol amine and bis-dimethylaminopropyl amine and the compound 1,3-propandiol and/or N-hydroxyoctanamide. It has been found that said hyperbranched copolymer synergistically enhances the antimicrobial action of a 1,3-propanediol and/or N-hydroxy-octanamide.

Compositions comprising specific hyperbranched copolymers together with 1,3-propandiol and N-hydroxyoctanamide

The present invention relates to cosmetic compositions which comprise a hyperbranched copolymer of the monomers dodecenyl succinic acid anhydride, diisopropanol amine and bis-dimethylaminopropyl amine having quaternary terminal groups and a liquid and/or solid organic UV-filter. The copolymer is used in a cosmetic composition comprising the UV-filter for reducing the material transfer to a contacted surface. Preferably the copolymer is polyquatemium-110.

Cosmetic composition comprising specific hyperbranched copolymers and organic UV filters

The present invention relates to topical compositions comprising at least one liquid UV-filter and a nano-sized 1,4-di(benzoxazol-2'-yl)benzene.

Topical composition

The present invention relates to a novel micronized 1,4-di(benzoxazol-2′-yl)benzene as well as to the use thereof in topical compositions.

Micronized 1,4-di(benzoxazol-2′-yl)benzene

The present invention relates to topical compositions comprising at least one polar oil and a micronized 1,4-di(benzoxazol-2′-yl)benzene having a mean particle size of at most 300 nm as well as to the use of such a micronized 1,4-di(benzoxazol-2′-yl)benzene to reduce the transfer of such oils to surfaces.

The present invention relates to topical compositions comprising D-panthenol, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) and hydroxyacetophenone (HAP) in specific weight ratios which show less staining.

The present invention relates to topical compositions comprising panthenol, hydroxyacetophenone and a micronized UV filter.

The present invention relates to topical compositions comprising erythrulose and hydroxyacetophenone as well as the use thereof for the prevention and/or treatment of ailments associated withyeast,as well as the protection against molds such as in particular

Topical compositions

The present invention relates to topical compositions comprising erythrulose and a caprylate, characterized in that the amount of the caprylate in the composition is 5 higher than the amount of erythrulose.

The present invention relates to propanediol monoacetate mononitrate as well as the use thereof as antimicrobial agent, in particular for cosmetic applications.

Propanediol monoacetate mononitrate

The present invention relates to the use of erythrulose as antimicrobial agent as well as to composition comprising said agent.

The present invention relates to topical compositions comprising phytantriol and erythrulose as well as the use thereof for preservation boosting.

Preservation booster

The present invention relates to topical compositions comprising 10-hydroxystearic acid or a salt thereof and at least one nonionic emulsifier. The present invention also relates to a method to retard or inhibit the re-crystallisation of 10-hydroxystearic acid or a salt thereof in a topical composition, said method comprising formulating 10-hydroxystearic acid or a salt thereof in the presence of at least one nonionic emulsifier.

10-hydroxystearic acid compositions

The invention relates to topical sunscreen emulsion comprising an oil phase and a water phase, wherein said emulsion comprises a phosphate ester emulsifier, phytantriol and an amount of at least 1 wt.-% based on the total weight of the topical sunscreen emulsion of at least one UV-filter substance. Furthermore, the invention relates to the use of phytantriol for improving the water resistance of such topical sunscreen emulsions.

Topical sunscreen emulsions

The present invention relates to topical compositions comprising 10-hydroxystearic acid or a salt thereof in combination with 12-hydroxystearic acid or a salt thereof. The present invention also relates to a method to retard or inhibit the recrystallization of 10-hydroxystearic acid or a salt thereof in a topical composition, said method comprising formulating 10-hydroxystearic acid or a salt thereof in the presence of 12-hydroxystearic acid or a salt thereof.
