Latex gloves are disposable gloves made from natural rubber latex, a milky fluid harvested from rubber trees. They’ve been a staple in healthcare, laboratories, and food handling for decades because of their excellent stretch, close fit, and reliable barrier protection against pathogens. About 40% of global rubber products come from natural rubber, and surgical and examination gloves remain one of its primary uses.
What Latex Gloves Are Made Of
Natural rubber latex starts as a liquid tapped from the bark of rubber trees, primarily grown in Southeast Asia. The raw latex contains a mix of rubber particles, water, and naturally occurring proteins. Those proteins are important to know about because they’re responsible for allergic reactions in some people.
To turn liquid latex into a usable glove, manufacturers use a process called vulcanization. Ceramic or metal hand-shaped molds are dipped into the latex compound, which also contains sulfur (a crosslinking agent), accelerators, and activators. The sulfur creates chemical bridges between rubber molecules, transforming the soft, sticky latex into an elastic, durable film. The coated molds are then heated at around 80°C for roughly two hours to finish the curing process. After vulcanization, the gloves are washed to reduce residual proteins and chemicals on the surface.
Why They Fit and Feel Different
Latex gloves are noticeably softer and stretchier than their synthetic counterparts. Mechanical testing shows that latex gloves have an elastic modulus of roughly 0.8 to 1.1 MPa, compared to 1.8 to 2.4 MPa for nitrile gloves. In practical terms, that means latex conforms more closely to the hand and provides better tactile sensitivity, which is why surgeons historically preferred them for delicate procedures.
Latex also holds up better with repeated use. When gloves were subjected to ten cycles of soap-and-water washing in lab testing, nitrile gloves lost 34% to 43% of their elasticity. Latex gloves, by contrast, showed no significant change or even a slight increase in stiffness. This durability under real-world stress is one reason latex remains popular in settings that require extended wear.
How Well They Protect
As a barrier against bloodborne pathogens and biological hazards, latex gloves perform very well. In a study simulating patient care conditions, latex gloves had failure rates of just 0% to 4% after manipulation meant to mimic real use. Nitrile gloves performed comparably at 1% to 3%. Vinyl gloves, however, failed at dramatically higher rates of 12% to 61% under the same conditions, making them a poor choice when infection control matters.
Straight out of the box with no handling, all three glove types performed similarly. The difference only became clear once the gloves were stretched, flexed, and stressed the way they would be during actual tasks. This is an important distinction: a glove that tests well sitting still may not protect you once you start working with it.
Chemical Resistance
Latex offers excellent protection against many water-based chemicals and some industrial compounds. According to EPA permeation testing, latex gloves resist ammonia, formaldehyde, chlorine, sodium hydroxide, and nitric acid for over eight hours with no detectable breakthrough.
Organic solvents are a completely different story. Acetone breaks through latex in about five minutes. Chloroform and dichloromethane penetrate in under four minutes. Toluene, benzene, xylene, and trichloroethylene all compromise the glove within minutes. Tetrahydrofuran breaks through almost instantly. If you’re working with any of these solvents, latex gloves provide essentially no protection, and nitrile or other specialty gloves are the appropriate choice.
Latex Allergy: A Real Concern
Roughly 4.3% of the general population has some form of latex allergy, and the rate climbs to about 9.7% among healthcare workers who handle gloves daily. There are two distinct types of reactions.
The more serious is a Type I hypersensitivity, an immediate immune response to the natural proteins in the rubber. Symptoms can range from hives and nasal congestion to, in rare cases, anaphylaxis. The second type, Type IV allergic contact dermatitis, is actually a reaction not to the latex itself but to the chemical accelerators used during manufacturing, particularly compounds called thiurams, carbamates, and mercaptobenzothiazoles. This delayed reaction typically shows up as itchy, red, cracked skin on the hands 24 to 48 hours after wearing the gloves.
Latex allergy is the main reason many workplaces have shifted to nitrile gloves as their default. People with known latex sensitivity should avoid latex gloves entirely, as repeated exposure tends to worsen the reaction over time.
The Powdered Glove Ban
Latex gloves were traditionally dusted with cornstarch powder to make them easier to slide on and off. In December 2016, the FDA banned all powdered medical gloves in the United States. The powder posed a direct risk: when it contacted internal body tissue during surgery, it triggered severe airway inflammation, granulomas (small masses of immune tissue forming around powder particles), and adhesions (scar tissue) that led to surgical complications. The powder also acted as a carrier for latex proteins, launching them into the air where they could be inhaled and trigger allergic reactions in sensitized individuals. All medical latex gloves sold today are powder-free.
Latex vs. Nitrile vs. Vinyl
Choosing between glove materials depends on what you’re using them for.
- Latex offers the best fit, stretch, and touch sensitivity. It provides strong barrier protection against biological hazards and many chemicals but fails against organic solvents. Not suitable for anyone with a latex allergy.
- Nitrile is the most common alternative. It matches latex in barrier protection, resists a broader range of chemicals (including many solvents), and carries no allergy risk from natural rubber proteins. It’s stiffer and less form-fitting, though modern nitrile gloves have narrowed that gap significantly.
- Vinyl is the cheapest option but also the least protective. Its high failure rates under real-use conditions make it suitable only for low-risk tasks like food preparation where there’s no contact with blood or hazardous materials.
Common Uses
Despite the rise of nitrile, latex gloves are still widely used in surgical settings where tactile precision matters most. They’re also common in dental offices, veterinary clinics, and some laboratory environments. Outside of healthcare, you’ll find them in food service, janitorial work, painting, and general household cleaning.
For any task involving organic solvents, petroleum products, or prolonged chemical exposure, latex is the wrong choice regardless of comfort. And in any shared workplace, it’s worth confirming that no one nearby has a latex allergy, since proteins can become airborne when gloves are snapped on and off.
