Researchers from the Institute of Chemistry of the University of Brasília (UnB) have developed a method for the production of hypoallergenic latex, used in the manufacture of condoms, surgical gloves, catheters and catheters. Other items. In addition to not causing allergies, the products may be more resistant. The process has already been patented

O that the researchers developed was a way to inactivate allergenic proteins in the natural rubber latex. "The latex is a very rich biological medium, we have more than 200 different kinds of proteins.However, 13 of them are allergens and can be harmful to health.When it is d & # 39; use the catheter in the position of contact very close to the mucosa, if the person is allergic can have anaphylactic shock and reach death, "says Professor Floriano Pastore Júnior, who directs research at the Institute of Chemistry from the institution.
In previous experiments, the proteins were removed from the latex to avoid allergy. "Instead, we switched to a different approach because we saw that Protein removal removed resistance from films made with latex, so the way to avoid this effect was to not remove proteins and block their action, which was made using tannin, made from bark tea of black acacia, tannin is used in tanning of animal skin, to turn it into leather.
"We use the chemical reaction of tannin with the protein of leather to protect the proteins of the latex.These proteins remain with a cover of vegetable tannin and do not develop. ” title=”Reprodução/TV Brasil/Agência Brasil”/>
