ABSTRACT:
Skin barrier paste compositions free from organic solvents comprised of at least a rubber component and a filler component wherein the rubber component includes a liquid rubber having an average molecular weight of about 1,000 to about 80,000 and a viscosity of about 200 poise to about 6,000 poise at 40.degree. C., the rubber component being present in the paste composition in the range of about thirty percent to about seventy percent by weight. The present inventive paste compositions can be freely formed with the fingertips or a spatula; they are less irritating to the skin, mucosa and/or the injured area; and they are less susceptible to a viscosity change when exposed to the atmosphere, thus assuring an ease of application and a stable paste formulation when stored in a container.
