  • Publication number: 20100158825
    Abstract: The invention provides for cosmetic and personal care compositions comprising a synthetic magnesium aluminosilicate clay. The synthetic magnesium aluminosilicate clay is formed at ambient pressure by a series of reaction steps and a pH change from acidic pH to basic pH. The characteristics of the magnesium aluminosilicate clay, including platelet size, degree of stacking, and porosity can be tuned depending on the cosmetic or personal care product desired. In addition, these cosmetic and personal care compositions optionally include one or more of the following components: odor controlling agents, skin protectants, diluents, lipophilic skin health benefit agents, sunscreens, humectants, emollients, slip compounds, and moisturizers.

  • Publication number: 20100087313
    Abstract: This invention is directed to a synthesis process for preparing magnesium aluminosilicate clays and to the products of said process. Briefly, a silicon component, an aluminum component, and a magnesium component are combined, under aqueous conditions and at an acidic pH, to form a first reaction mixture and subsequently the pH of the first reaction mixture is adjusted to greater than 7.5 to form a second reaction mixture. The second reaction mixture is allowed to react under conditions sufficient to form the magnesium aluminosilicate clay of the present invention. The invention is also directed to catalyst compositions comprising the magnesium aluminosilicate clays synthesized according to the process of the invention. The resulting magnesium aluminosilicate clay can be used as a catalyst or as a component in catalyst compositions.

  • Publication number: 20100084311
    Abstract: This invention is directed to hydrodemetallization catalysts and hydrodemetallization processes employing a magnesium aluminosilicate clay. The magnesium aluminosilicate clay has a characteristic 29Si NMR spectrum. The magnesium aluminosilicate clay is the product of a series of specific reaction steps. Briefly, the magnesium aluminosilicate clay employed in the catalyst and process of the invention is made by combining a silicon component, an aluminum component, and a magnesium component, under aqueous conditions and at an acidic pH, to form a first reaction mixture and subsequently the pH of the first reaction mixture is adjusted to greater than about 7.5 to form a second reaction mixture. The second reaction mixture is allowed to react under conditions sufficient to form the magnesium aluminosilicate clay. The resulting magnesium aluminosilicate clay combines high surface area and activity for use in hydrodemetallization catalysts and processes.
