  • Publication number: 20060251741
    Abstract: Disclosed are stable, homogeneous dispersions, comprising (a) from about 20 to 90% by weight of a first composition comprising (i) about 60-95% by weight of a first polar solvent, (ii) about 0-40% by weight of one or more second polar solvents, and (iii) water soluble components of a first natural product; and (b) from about 10 to 60% by weight of a second composition comprising: (i) one or more apolar solvents, and (ii) oil soluble organic components of a second natural product; and (c) from about 0.01 to 8% by weight of a non-surface active lipid phosphate or a surface active agent. Also disclosed are methods of forming the stable, homogeneous dispersions of the invention, comprising forming a first composition comprising water soluble components of a first natural product; forming a second composition comprising oil soluble organic components of a second natural product; mixing the compositions and subjecting the mixture to high pressure high shear processing to form a stable, homogeneous dispersion.

  • Publication number: 20050186160
    Abstract: The present invention relates to a sunscreen formulation which exhibits superior ultraviolet protection and water resistance than prior art sunscreen compositions. The sunscreen formulation comprises (a) a dispersion comprising a sunscreen active agent and (b) a base composition comprising a rheological modifying agent and water. The sunscreen formulation is substantially free of surfactants. According to a preferred embodiment, the sunscreen active agent is ethylhexylmethoxycinnamate, butylmethoxydibenzoylmethane, or a combination thereof. The sunscreen formulation preferably comprises a phosphorylated starch derivative as a Theological modifying agent. Another embodiment of the present invention is a method of protecting skin or hair from ultraviolet radiation by applying an effective amount of the sunscreen formulation of the present invention to the skin or hair.

  • Publication number: 20050021174
    Abstract: A method and system for selecting and producing a customized cosmetic or pharmaceutical formulation is disclosed below. The system can be implemented in an Internet based system or a stand-alone version, such as a Kiosk. An improved method of custom formulation is presented which utilizes the user's preferences and profile, as well as external factors. The customized formulation can be directed to a manufacturing facility for on-demand production. Alternatively, a printout of the formulation can be provided for subsequent use at point-of-sale locations, such as a cosmetics store or a pharmacy. The custom formulation software can also be provided in conjunction with a cosmetics manufacturing kit for use in home or business application.
