  • Patent number: 6054525
    Abstract: A semi-synthetic rubber latex. The rubber employed in the latex is natural rubber obtained from plant life known to produce polyisoprene. Surprisingly, the semi-synthetic rubber latex is essentially devoid of those proteins that are known to give rise to natural rubber allergenicity or hypersensitivity, and are also essentially devoid of antigens that potentially will give rise to immune responses. Also provided is a method for obtaining the semi-synthetic rubber latex and dipped films thereof that are also substantially free of known natural rubber allergens.

  • Patent number: 5910567
    Abstract: A method for producing a formed product of deproteinized natural rubber latex capable of reducing a content of an allergen in a natural rubber latex material to a level sufficient to keep the latex from being harmful to the human body without decreasing yields of the product and deteriorating formability of the latex. In the method, cleaning removal of a non-rubber content is carried out after each of protein decomposition, prevulcanization and forming. An aqueous alkali solution, ammonia, water containing free chlorine in an amount of 0.005 to 0.02% by weight or alcohol-water mixed liquid containing alcohol in an amount of 5 to 80% by weight is used as cleaning liquid for the cleaning removal. The method is suitably applied to production of a natural rubber product such as a rubber glove, a condom, a catheter, a foam rubber material and the like.
