ABSTRACT:
A method for reducing allergenicity of natural latex rubber. The natural latex rubber, prior to its vulcanization, is admixed with mineral oil and extracted to reduce protein levels therein. Ideally, the mineral oil is characterized as having a density of approximately 0.818 to 0.880 and a viscosity of approximately 33.5 cf at 40° C.
