Abstract

The invention concerns cosmetic agents with condensates of plant and animal decomposition products, which can be used in cosmetic body care and cleansing preparations and which, in addition to the emulsifying effect, have essential skin-care properties. The object of the invention is to prepare cosmetic products from plant and animal starting materials, said products having substantial portions of original biological structures but being modified to such an extent that they are cosmetically acceptable owing to their neutral smell and pale color. According to the invention, the cosmetic agent is a product of a direct and mild (20 to 55.degree. C.; pH 7.5 to 8.5) decomposition of a biological starting material in an aqueous medium, subsequent condensation with a sub-stoechiometric amount of a C.sub.10 to C.sub.20 fatty acid halide or mixture and optionally subsequent etherification or esterification of the condensation product. The starting materials can be yeasts, yeast fractions, pulses, pulse fractions, pectins, pectin-containing masses, algae, algae fractions, animal milk, animal milk fractions and their mixtures, and contain helical natural substance components, enzyme structure…
