  • Patent number: 6843995
    Abstract: The invention relates to a cosmetic preparation containing an active complex comprised of extracts. The active complex contains at least one starting substance, which is extracted as an aqueous extract from real truffles (Tuberaceae) and which is provided in a cosmetically acceptable gel while being stabilized. A preferred active complex is one that additionally contains a champagne product. Cosmetic preparations containing this active complex lead to an improved stimulation of the immune system, an improved regenerative effect and thus to an improved balance in the ecosystem of the skin.

  • Patent number: 6820014
    Abstract: The invention relates to a new method for determination of realistic UV protection factors or bread spectrum indices of a sunscreen preparation. Realistic UV protection factors are calculable by determination of the theoretical and the experimental UV absorbances of known UV filters in wavelength steps of about 5 nm in the range of 290-400 nm from a definite basic formulation (emulsion, gel etc.) and on a transparent substrate and introducing of the values in a mathematical model. These factors are in conformity with values measured in vivo. The number of the experiments for developing new formulations are significant reduced because only basic formulation, kind and concentration of the filters have to enter.

  • Publication number: 20030087796
    Abstract: The invention relates to novel aromatic compositions consisting of HLA molecules, which two different potential perfume carriers are assigned. The invention aims at developing novel aromatic compositions consisting of HLA molecules based on the selection of alleles of genes which are relevant from an olfactory viewpoint and subsequent processing thereof. According to the invention, the aromatic compositions are produced by selecting one allele amongst known class I HLA alleles, which differs in at least one characteristic from other alleles of HLA class I molecules and which is present in less than 5% of individuals of the world population; the protein that is coded for by the selected allele undergoes assembly in the presence of &bgr;2-microglobulin (&bgr;2m); the formed HLA class I molecules are purified with the bonded peptides and fragmented with the protease, and the odor-active substances resulting from fragmentation are added as individual components or as a mixture to a cosmetic preparation.
