So, I was wondering about a quick checkup on the causes of latex allergy. Indeed, this is not caused due to the primary latex chemical itself, but is caused due to an antigenic proteins found in natural rubber latex, intended by the trees as a means to keep the bugs away. Indeed, it does keep bugs away, but it also causes humans to tend to develop allergic reactions from long-term exposure to natural rubber latex. Luckily, natural rubber latex can be processed to remove this, and synthetic latex similar to the natural formulation need not contain any of this at all.

Another interesting material sometimes touted as an alternative, and general material to consider for chemical safety evaluation: Spandex. Spandex is made from polyether-polyurea copolymer. It looks like Spandex might not contain any chemicals with 5-member or 6-member carbon rings, so it could be that Spandex cannot easily transform into endocrine disruptors.
