Abstract
A urea-containing component of a skin care agent or skin preparation, wherein the urea forms inclusion compounds with fatty acids and/or fatty acid compounds, so that fat is made available for skin care which is protected against oxidation. A method of manufacturing the urea-containing component of a skin care agent includes cooking an oil or a mixture of fatty acid ethyl esters manufactured from an oil with urea in a solvent in a non-oxidizing atmosphere until the urea has been dissolved, permitting the mixture to cool, and finally cooling the mixture to a final temperature of below 10.degree. C. and separating the resulting precipitate.
