A METHOD FOR PREPARING A NATURAL RUBBER LATEX FREE FROM PROTEINS

摘要

A natural rubber latex containing substantially no proteins which is specified by 14, 31 and 4 5 kDa bands in SDS-PAGE measurement, and a process producing this latex by saponification of natural rubber latex with alkaline hydroxide in the presence of a surfactant. The natural rubber latex of the present invention can be suitably applied to the production of rubber products such as catheter, rubber glove, condom, and foam rubber, because it contains substantially no proteins which cause Type I allergy.
