  • Publication number: 20120076876
    Abstract: Ethanolic chia (Salvia hispanica) seed extracts are provided in a system including one or more polyols and at least one hydrophobic compound that solubilize hydrophobic and slightly hydrophilic fractions of the extracts. The polyol can be pentylene glycol. The at least one hydrophobic compound can be a light oil or an ester including, but not limited to, glyceryl caprylate, glyceryl trioctanoate, isodecyl neopentanoate, isononyl isononanoate, isopropyl myristate, phenethyl benzoate, propylene glycol dicaprylate/dicaprate, propylene glycol dioctanoate and combinations thereof. The system or solution can form a cosmetic composition which is highly stable. A method for preparing the composition also is provided.

  • Publication number: 20100214421
    Abstract: A process for measuring skin color parameters from a digital photograph using novel color correction algorithms is described. The process includes measuring color values of a digital color photo, correcting the color deviation of each picture to that of a standard color, and converting the corrected RGB values and generating an output that is useful to L*a*b* values to describe changes in the color properties of the photographed skin.

  • Patent number: 7556605
    Abstract: The invention relates to methods of measuring the overall elasticity of skin and determining the portion of the overall elasticity that is due to elastic properties and the portion of overall elasticity that is due to viscoelastic properties of the skin and correlating the results of the measurement to an individual's chronological age. The invention also relates to methods of measuring improvements in a person's skin health by measuring elasticity before, during and after human clinical trials of topical and/or oral treatment compositions. The parameters for determining elasticity are based on areas that are defined on a deformation/relaxation curve and require that an inflection point be determined for each skin sample analyzed.

  • Patent number: 7094395
    Abstract: A method for producing a colored cosmetic composition having inorganic pigments resistant to agglomeration in an oil-in-water emulsion. The method includes the following: preparing an oil dispersion by adding inorganic pigments directly to an oil; preparing an aqueous base that includes water; combining the oil dispersion and aqueous base; and partitioning the inorganic pigments between the oil and the aqueous phase under controlled conditions, for example, hydrophile-lipophile balance, agitation time and speed, and cooling rate. The present invention provides a process to easily disperse iron-oxide pigments, even black iron-oxide pigments, in oil-in-water emulsions. The present invention provides colored cosmetic compositions that have excellent properties, such as smoothness, adhesion to skin, uniform color, ease of removal, smudge resistance and non-oiliness.

  • Patent number: 6221664
    Abstract: This invention is a vaccine prepared from antigen-antibody-recombinant plasmid DNA complex. This invention is a complex vaccine composed of at least one microbial source antigen and its (their) specific antibody or specific immunoglobulin complexed with one or more recombinant DNA(s) from the gene or genes of microbes. Immunization with this complex vaccine induces enhanced specific humoral and cellular immune responses in infected individuals with immune tolerance or immune defects against specific microbial infections. The advantages of this complex vaccine are: antigen presentation via various modes; more rapid induction of immune responses; less amount of components required to induce immune responses; increased stability of the vaccine; and can be applied by injection, intranasal or other routes of topical immunization.
