  • Patent number: 9072683
    Abstract: The present invention is directed to the use of xanthan gum, particularly heat treated xanthan gum, as a fixative in hair cosmetic compositions. Xanthan gum is advantageous in that it may be used with other hair fixatives and provides rheology modifying and other properties including excellent stiffness, gloss, dry comb, wet comb, non-flake, anti-static, feel and high humidity curl retention.

  • Patent number: 7816310
    Abstract: A personal care composition having at least one hydroxyalkylurea (HAU) optionally in combination with at least one other moisturizing agent. The at least one HAU, alone or together with the at least one moisturizing agent, provides not only the perception of moisturization, but also actual increased moisturization efficacy. When the two are used in combination in a personal care composition, they are provided in a synergistically moisturizing effective ratio to provide that perception of moisturization and increased moisturization efficacy. Such personal care compositions provide an enhanced smooth feel as well as enhanced flexibility, elasticity, suppleness and firmness without leaving a heavy or greasy feel.

  • Publication number: 20030031722
    Abstract: The present invention is directed to an aqueous personal care or cosmetic formulation containing a starch-encapsulated hydrophobic compound. These formulations are stable, and allow for formulations containing hydrophobic ingredients without the need for additional surfactants or emulsifiers. The starch-encapsulated hydrophobic compound is formed by jet cooking a mixture of the starch and the hydrophobic compound. Useful formulations include a wide variety of personal care and cosmetic formulations, including skin and hair care formulations.
