Report of a case of erythema multiforme-like eruption due to the use of rubber gloves. After several complementary studies, including epicutaneous and skin prick tests, we concluded that the eruption was secondary to sensitization to carbamates and thiuram. The main differential diagnosis in this case was allergic contact dermatitis to latex in natural rubber gloves. This entity is less frequen...

The non-rubber components present in natural rubber latex can contribute to the dark color of dried films and may cause allergic reactions. This project aimed develop light-color with minimal protein contamination. Various additives were incorporated, a leaching procedure was implemented address this issue. evaluation focused on content, changes, swelling properties thin films. Texapon N70 prov...

This study aimed to develop an adhesive for silicone maxillofacial prostheses and compared the properties with Daro hydrobond (Factor II, Inc, Lakeside, AZ, USA). Two adhesives were developed from non-vulcanized natural rubber-based (Adhesive A) deproteinized rubber latex (DNRL) products B) stored at 4 °C. The Control group was commercial physical (appearance, viscosity, spreadability, color, p...

Natural rubber is synthesized in specialized articulated cells (laticifers) located in the inner liber of Hevea brasiliensis. Upon bark tapping, the laticifer cytoplasm (latex) is expelled due to liber tissue turgor pressure. In mature virgin (untapped) trees, short-term kinetic studies confirmed that ethylene, the rubber yield stimulant used worldwide, increased latex yield, with a concomitant...
