The present disclosure relates to specific (poly-)glycerol partial esters with at least one carboxylic acid and one polyfunctional carboxylic acid, and to the use thereof as emulsifier and to formulations comprising partial esters of the present disclosure.

Partial esters of a polyglycerol with at least one carboxylic acid and one polyfunctional carboxylic acid, their preparation and use

The invention relates to a process for the preparation of a plant extract fromplants, characterized by the process steps process step A) liquid extraction ofrhizomes, process step B) optionally, separation of a curcuminoid-containing solid obtained by precipitation from the extraction mixture obtained in process step A), process step C) removal of solvents present from the extraction mixture obtained in process step A) or B) to obtain a concentrate and process step D) distillation of the concentrate at a pressure of less than 1 bar to give the extract as distillate.

Bioactive composition for cosmetic applications

Compounds of the general formula and to the use thereof for controlling microorganisms are provided.

Antimicrobial compositions

The application relates to a method for the synthesis of finely particulate organic tin (oxy) fluorides by reacting mono-organic or diorganic tin oxides or hydroxides with fluoric acid, the reaction being carried out in the presence of surface active compounds.
