  • Patent number: 6706811
    Abstract: The invention discloses an efficient and convenient method for the preparation of an aqueous emulsion of an organopolysiloxane having long-chain alkyl groups bonded to the silicon atoms. Instead of dispersing and emulsifying an organopolysiloxane modified in advance with long-chain alkyl groups in an aqueous medium, as is the case in the prior art method, an organohydrogenpolysiloxane having silicon-bonded hydrogen atoms and a long-chain &agr;-olefin compound are co-emulsified in an aqueous medium containing a surface active agent and this aqueous emulsion is heated under agitation with addition of a catalytic platinum compound so as to effect the in situ hydrosilation reaction between the silicon-bonded hydrogen atoms in the organohydrogenpolysiloxane and the ethylenically unsaturated bonds in the &agr;-olefin compound. The aqueous emulsion prepared by the inventive method exhibits excellent stability against long-term storage, dilution with water and mechanical shearing force.

  • Patent number: 6517941
    Abstract: An object of the present invention is to provide a coating composition with which it is possible to make coated paper that is excellent in various properties such as glossiness, water resistance, solvent resistance, heat resistance, thermal blocking resistance and ink penetration and that can readily be recycled. This object of the invention can be attained by a coating composition comprising a hydrosol emulsion and colloidal silica, wherein the hydrosol emulsion is obtained by neutralizing, with an alkali, a synthetic resin emulsion prepared by dispersing, in water, particles of a synthetic resin having carboxyl group and an alkoxysilyl group.

  • Publication number: 20020193513
    Abstract: The invention relates to a composition for cosmetic or topical application comprising particles of an at least partially crosslinked elastomeric solid polyorganosiloxane suspended in an aqueous phase, wherein the composition is substantially water-resistant. This composition is more especially a make-up composition or a care composition for the lips or a foundation composition for making up the human face or body. This composition is soft and feels fresh when applied, it spreads easily, it is non-sticky and it does not dry out the skin or the lips. It is entirely suitable for greasy skin, on account of its high matte-effect power.

  • Publication number: 20020183445
    Abstract: The invention discloses an efficient and convenient method for the preparation of an aqueous emulsion of an organopolysiloxane having long-chain alkyl groups bonded to the silicon atoms. Instead of dispersing and emulsifying an organopolysiloxane modified in advance with long-chain alkyl groups in an aqueous medium, as is the case in the prior art method, an organohydrogenpolysiloxane having silicon-bonded hydrogen atoms and a long-chain &agr;-olefin compound are co-emulsified in an aqueous medium containing a surface active agent and this aqueous emulsion is heated under agitation with addition of a catalytic platinum compound so as to effect the in situ hydrosilation reaction between the silicon-bonded hydrogen atoms in the organohydrogenpolysiloxane and the ethylenically unsaturated bonds in the &agr;-olefin compound. The aqueous emulsion prepared by the inventive method exhibits excellent stability against long-term storage, dilution with water and mechanical shearing force.
