Abstract: Production of peat-extracts for use in cosmetics from water-containing peat comprises drying and milling.  Also included are Independent claims for the following production of cosmetics: (A) a skin cleanser comprising natural brine (below 30%), peat-extract (below 10%), EtOH (below 5%), mild surfactant combination (below 2%), supplementary care components (below 2%) and deionized water, perfume, preservatives etc (balance) by dissolving the surfactant combination in deionized water and then stirring the other components sequentially at room temperature with the concentrations (especially of the natural brine) such that the cleanser is stable for 24 hours at 5 deg C as a clear or opaque solution;  (B) a removable damp mask comprising natural brine (below 30%), dry powdered peat (below 1%), propylene glycol (below 20%), EtOH (below 15%), electrolyte-stable, film-forming hydrogel-former (below 5%), spreadable lipids (below 5%), supplementary care components (below 5%) and deionized water, perfume, preservatives etc (balance) by heating the hydrogel-former in a water/natural brine mixture to give a smooth gel and then adding the other components while cooling the gel;  (C) a wash-off moist mask comprising natural brine (below 30%), dry powdered peat (below 1%), glycerin (below 35%), EtOH (below 15%), electrolyte-stable hydrogel-former (below 5%), cyclomethicone (below 5%), supplementary care components (below 5%) and deionized water, perfume, preservatives etc (balance) by a method as per (B);  (D) a peeling mask comprising natural brine (below 35%), dry powdered peat (below 5%), glycerin (below 15%), EtOH (below 10%), bentonite (below 10%), spreadable lipids (below 5%), natural abrasives (below 5%) and deionized water, perfume, preservatives etc (balance) by heating the bentonite with the water/natural brine mixture to form a highly viscous gel and then intensively mixing with the other components; (E) a night cream comprising natural brine (below 40%), peat-extract (below 5%), W/O adsorption base (below 15%), liquid paraffin (below 20%), spreadability improver (below 5%), supplementary care components (below 5%) and deionized water, perfume, preservatives etc. (balance) by adding the water/natural brine mixture at 80 deg C into a homogeneous fat phase containing the peat-extract and adding the temperature-sensitive components at room temperature; and  (F) a day cream comprising natural brine (below 40%), peat-extract (below 5%), fat with spreadability improver and consistency-imparting agent (below 20%), nonionic, electrolyte-stable O/W emulsifier (below 10%), glycerin (below 5%), supplementary care components (below 5%) and deionized water, perfume, preservatives etc (balance) by working the water/natural brine mixture at 75 deg C into the homogeneous fat phase by a conventional O/W process and then adding the peat-extract and temperature-sensitive components at room temperature.
