Abstract
The invention relates to cosmetic agents which contain, besides the usual basic cosmetic substances, natural yeast cell contents. The yeast cell contents are obtained by mechanically breaking open the yeast cell walls and by separating off the cell walls and any cell membranes, employing protective conditions. The invention relates also to extracts of yeast cell contents which contain an enriched fraction of yeast cell nuclei and which, when used in cosmetic agents, have an especially good skin-care effect. The native yeast cell contents comprise the cell contents without the cell walls, or the cell contents without cell walls and without nuclear membranes.
Claims6
A cosmetic agent suitable for application to the skin comprising the usual basic cosmetic substances, and natural extract of yeast cell contents obtained by destroying yeast cell walls and breaking open yeast cells, the resulting natural extract of yeast cell contents being free of yeast cell walls in an amount in the range of 2 to 20 wt. % for the extract of yeast cells based upon the total weight of the cosmetic agent.
A method for manufacturing a cosmetic agent containing yeast in addition to usual basic cosmetic substances, comprising the steps of simultaneous cooling yeast cells, smashing the yeast cells by mechanical means at a temperature of about 0.degree. C. to about 5.degree. C., separating off by means of at least one of centrifuging and filtering at a temperature of 0.degree. C. to about 5.degree. C., the non-destroyed yeast cells, the yeast cell walls and any yeast cell nuclear membranes and combining the resulting natural extract of yeast cell contents together with the usual basic cosmetic substances to form a cosmetic agent.
