Abstract
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.
