The dangerous theater of common misconceptions
The myth of the double-layer barrier
Many laboratory technicians believe that layering two pairs of standard latex or nitrile gloves provides a bulletproof defense against chemical intrusion. Still, physics disagrees. If the material is susceptible to molecular degradation, doubling the thickness only buys you a few more seconds of false security. Because acetone is a small, polar molecule, it navigates through the interstitial spaces of lower-grade polymers with terrifying efficiency. You might think you are safe. You are actually creating a moist, warm environment that accelerates skin absorption once the barrier inevitably fails. Permeation rates do not simply add up; the chemical can become trapped between the layers, forcing it directly into your pores. And isn't it ironic that the very thing meant
