  • Patent number: 5362488
    Abstract: A buffered skin cream containing a linear polydimethylsiloxane polymer, a non-ionic emulsifier, aloe vera, mineral oil, sodium citrate, citric acid, a blend of propylene glycol, diazolidinyl urea, methyl paraben and propyl paraben, and water. The buffering capacity of the cream is provided through the incorporation of citric acid and sodium citrate in the composition. The buffering system results in the cream having a preferred pH in the range of about 4.5 to 6.0, and most preferably a pH of about 5.2 which neutralizes acidic and basic by-products of urine and fecal matter. The cream has a preferred viscosity in the range of 100,000-2,000,000 centipoise and a most preferred viscosity of about 250,000 to 1,000,000 centipoise. The cream is easily washed off with soap and water and is useful in the protection and treatment of diaper rash.

    Abstract: The improved cleansing cream has a wrinkle-reducing effect when periodically applied to and rubbed into the human skin in wrinkled skin areas. The cream is non-irritating to the skin and includes a plurality of water-soluble granules which are of sufficient size, quantity and hardness to abrade the keratinized outer epidermal layer of the skin. The granules may be one or more inorganic salt, but preferably include one or more water-soluble vitamins and/or water-soluble vitamin-yielding salts, The cream also includes a base in which the granules are substantially uniformly disposed. The base preferably is in a major proportion with respect to the granules and is an oil and a petrolatum jelly. The water-soluble granules do not clog the pores of the skin but are absorbed into and nourish the skin.

  • Patent number: RE34579
    Abstract: The monamine oxidase inhibitor drug L-deprenyl (phenylisopropyl methyl propynyl amine) is safely and conveniently used for the treatment of mental depression in a formulation applied to the skin of the patient. In this way the danger of side reaction due to the consumption of foods containing tyramine (the cheese effect) is minimized. Unlike other monamine oxidase drugs, such as Parnate, L-deprenyl does not cause skin irritation when used in this way.
