Gloves do not protect you from exposure to all chemical reagents.
How your last line of defense is evaluated.
Breakthrough Time and Permeation Rate are reported by glove manufacturers for chemical resistance.
Breakthrough Time – Measures the time it takes for a chemical (how long) to permeate through the glove material in sufficient quantities to be detected (measured in minutes), and
Permeation Rate – Measures the quantity of chemical (how much) has permeated an area of the glove material after steady-state permeation has been achieved (measured in mg/m2/min)
Gloves have specific resistance to chemical reagents.

EHS TODAY online has 2002 information about “N-DEX® Free” the only disposable rubber glove that can be labeled “non-allergenic”. http://ehstoday.com/mag/ehs_imp_35853.
Workers that are allergic to latex and accelerators have had their livelihoods threatened. Remember, sensitivity to these allergens can build up over time, so that reactions may occur many years into a person’s career. For those workers, latex-free, accelerator-free gloves could be the answer they’ve been waiting for. By using this glove, sensitized workers can remain in their chosen occupation without suffering from painful and debilitating skin allergies. (Groce)
