Abstract
A method for lowering the extractable protein content in a natural rubber latex to below 30 parts per million (ppm) comprises the steps of treating by washing a rubber article, such as a rubber glove, with an aqueous solution containing a soluble silicate and, optionally, a protease. The methods claimed effectively reduce the allergenicity of the articles so treated.
