Abstract

La présente invention concerne un procédé permettant de réduire l'allergénicité de produits en latex de caoutchouc naturel provoquée par des allergènes en abaissant les teneurs en protéines extractibles de ces produits. Ce procédé consiste à soumettre ces produits à un lavage dans une solution fortement alcaline de façon à détériorer les allergènes. L'invention concerne également un système permettant de réduire l'allergénicité de produits en latex de caoutchouc naturel en abaissant les teneurs en protéines extractibles de ces produits. L'invention concerne enfin un produit, tel qu'un gant ou un préservatif, fabriqué en latex de caoutchouc naturel.
