Abstract: Foamable cosmetic creams for application onto the skin, comprising a selected creamy oil-in-water emulsion and a selected propellant, which may be and advantageously is a single propellant gas, are disclosed. Improvement of the froth properties is effected by predetermined control of the ingredients of the composition and their proportions, comprising specific percentage ranges of nonionic emulsifier, oil portion, consistency-providing agent, and water, a viscosity of the starting cream emulsion formed therefrom between about 200 and 500 mPas, and the propellant employed, which consists essentially of nitrous oxide or carbon dioxide, preferably nitrous oxide.

Abstract: The invention concerns a collagen sponge which has a denaturation temperature of at least 37.degree. C., is not cross-linked and in one of its two embodiments forms an optically clear solution in aqueous medium. As compared with the collagen sponges previously known, it is particularly suitable as support material for pharmaceutical and cosmetic active substances since it has a higher denaturation temperature than the latter and dissolves again in contact with body fluid. The collagen sponge of the invention is prepared from an optically clear collagen solution by precipitation with neutral salts, dissolving and reprecipitation and then subjecting the collagen to freeze-drying without removal of the precipitation salt. Acid-swollen collagens and/or cellulose or cellulose derivatives can also be added to the solution, whereby the physical properties of the collagen sponge can be affected.

Abstract: N-oxides of pyridyl carboxylic acid esters of the following formula are described: ##STR1## wherein R is ##STR2## wherein X is a hydrogen atom, straight or branched C.sub.1 -C.sub.5 -alkyl, C.sub.5 -C.sub.12 -cycloalkyl, 1-adamantyl, or cyclohexylacetyl, andwherein Y is a hydrogen atom, straight or branched C.sub.1 -C.sub.5 -alkyl, 2-ethylbenzofuranoyl-3, C.sub.5 -C.sub.12 -cycloalkyl, or 2-[(4-chlorophenoxy)-2-methylpropanoyloxy]ethyl;a process for the manufacture thereof, pharmaceutical compositions containing these compounds, and method of using the same. These compounds are suited for use in the treatment of hyperlipidemas.
