Abstract

A hand sanitizing composition and a method of manufacture, wherein the composition includes a solvent from about 78% to about 96% by weight sufficient to operate as a carrier and solvent. The composition includes tetrasodium EDTA and/or Sodium Citrate from about 0.01% to about 1% by weight to operate as a buffer, stabilizer and chelating agent. The composition includes a humectant selected from the group of humectants consisting of: Cetyl Alcohol, Ceteryl Alcohol, and Steryl Alchohol from about 1.5% to about 5.5% by weight to emulsify, thicken and lubricate. The composition includes an emollient from about 0.1% to about 3.2% by weight and an antioxidant vitamin from about 0.01% to about 1% by weight. The composition includes a soothing agent in a therapeutically significant amount and a conditioner.
