主权项

1. A cosmetic or dermatological preparation, wherein the preparation is free from emulsifiers, exhibits graininess and is obtainable by a process which comprises:
(a) dispersing one or more polyacrylic acid polymers in water to form a dispersion, (b) melting one or more fatty alcohols and
(b1) at least one wax and/or(b2) a mixture of liquid and solid hydrocarbons, where at least the hydrocarbon mixture has a melting range of from 5° C. to 75° C. according to DSC to form a mixture, (c) thoroughly mixing the dispersion and mixture obtained in (a) and (b) without effecting complete homogenization, incomplete homogenization causing the graininess of the preparation, and (d) optionally, adding one or more substances selected from neutralizing agents, skin moisturizers, preservatives, oils, thickeners and perfumes; and wherein the preparation comprises at least one crystallite which comprises at least the one or more fatty alcohols and the at least one wax (b1) and/or the mixture of liquid and solid hydrocarbons (b2).
