  • Patent number: 5525346
    Abstract: A diaper or diaper is impregnated with a skin lotion containing a linear polydimethylsilorane polymer, a non-ionic emulsifier consisting of polyoxyethylene sorbitan fatty acid esters, sorbitan fatty acid esters, polyoxyethylene alcohols, or polyoxyethylene fatty ethers, aloe vera, an alkoxylated ether/ester, sodium citrate, citric acid, a blend of propylene glycol, diazolidinyl urea, methyl paraben, and propyl paraben, and water. Most preferably, the buffering system results in the lotion having a pH of about 5.2 which neutralizes acidic and basic byproducts of urine and fecal matter.
    Type: Grant
    Filed: April 12, 1995

  • 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.
