  • Patent number: 5208360
    Abstract: Compositions and a method of delivering a humectant to a surface such as skin by forming a reaction product of the humectant with an organosilicon compound. The reaction product is applied to the skin surface and contacted with moisture which causes the reaction product to undergo hydrolysis on the skin surface. This releases free humectant onto the skin surface and the silanol functional organosilicon compound formed as a result of the hydrolysis can be utilized on the skin surface as a durable water repellent and softening ingredient for the skin.

  • Patent number: 5189067
    Abstract: A method of treating human skin to enhance the ability of skin in the absorption and retention of moisture in order to retard skin moisture loss. There is applied to skin an organosilicon compound exhibiting humectant-like characteristics which is an anionic siliconate. An alternate method treats human skin to reduce the transepidermal water loss of skin in order to increase moisturization and to enhance skin softness. There is applied to skin an occlusive film forming organisilicon compound which is also a siliconate.

  • Patent number: 5169904
    Abstract: A method for altering a macroporous cross-linked hydrophobic copolymeric lattice produced by precipitation polymerization in a solvent of at least one monounsaturated ester monomer and at least one polyunsaturated ester monomer soluble therein, in order to render the hydrophobic copolymeric lattice hydrophilic. The method involves saponifying the hydrophobic copolymeric lattice by reacting the surface of the hydrophobic copolymeric lattice with an aqueous alkali. The surface can also be rendered hydrophilic by polymerizing an acrylate monomer onto the lattice in order to form a surface containing carboxylic acid sites. The carboxylic acid sites formed on the surface of the lattice are converted to carboxylate anions.
