Latex gloves are disposable hand coverings made from natural rubber, a milky fluid harvested from the Hevea brasiliensis rubber tree native to the Amazon basin. They’ve been the standard in medicine, dentistry, and laboratory work for decades because they offer an exceptionally close fit and superior touch sensitivity compared to synthetic alternatives. While newer materials like nitrile have gained ground, latex gloves remain widely used wherever precise hand movements matter.
What They’re Made Of
Natural rubber latex starts as a liquid tapped from the bark of rubber trees, similar to how maple syrup is collected. That raw liquid is then processed into a stretchy, durable film through a chemical treatment called vulcanization, which uses crosslinking agents to strengthen the rubber at a molecular level. During manufacturing, the liquid latex is shaped over hand-shaped molds, dried, and cured.
Some gloves undergo additional treatments after forming. Chlorination, for example, hardens the surface slightly and reduces stickiness, making gloves easier to put on and take off. Historically, manufacturers dusted gloves with cornstarch powder to prevent them from sticking together in the box, but powdered medical gloves were banned in the United States effective January 2017. The FDA determined that the powder could become airborne, carrying latex proteins into the lungs and triggering severe airway inflammation, allergic reactions, asthma, and tissue adhesions during surgery.
Medical Grade vs. Industrial Grade
Not all latex gloves meet the same quality standards. The key difference comes down to a metric called the Acceptable Quality Level, or AQL, which measures how many defects (mainly pinholes) are allowed per batch of 100 gloves. Medical examination gloves must have an AQL of 2.5 or lower, meaning fewer than 2.5 defective gloves per 100. Many medical gloves are actually manufactured to an AQL of 1.5 or better. Industrial-grade gloves, by contrast, are allowed an AQL of up to 4.0.
That difference matters. A glove rated for industrial use only should never be used around bodily fluids, hazardous drugs, or any situation where barrier integrity is critical. If you’re buying gloves for home medical care, wound cleaning, or food handling, look for the medical-grade designation on the box.
Sterile vs. Non-Sterile Gloves
Within the medical category, latex gloves come in sterile and non-sterile versions. Sterile gloves are individually packaged and treated to eliminate all microorganisms. They’re standard for surgical procedures where preventing wound infections is essential. Non-sterile examination gloves come packed in bulk boxes and are used for routine tasks like physical exams, blood draws, and basic patient care.
For minor procedures like stitching up lacerations, skin excisions, or wound repairs in emergency and outpatient settings, the distinction may be less important than you’d expect. A systematic review published in JAMA Surgery found no statistically significant difference in infection rates between sterile and non-sterile gloves for these types of minor wound repairs. Sterile gloves remain the standard for operating rooms and any procedure involving deep or internal tissues.
Why Latex Feels Different From Other Gloves
Latex’s defining advantage is its natural elasticity. The material conforms tightly to the shape of your hand, creating what users often describe as a second-skin fit. This gives latex gloves excellent tactile sensitivity, the ability to feel fine details through the glove. Surgeons, dentists, and lab technicians have long preferred latex for this reason: you can distinguish textures, detect small objects, and perform delicate manipulations more easily than with thicker or stiffer alternatives.
The tradeoff is durability. Latex gloves have moderate puncture resistance, meaning they’re more prone to tearing or developing small holes during rough tasks compared to nitrile gloves, which rate higher for puncture and abrasion resistance. For work involving sharp objects, heavy friction, or extended wear under physical stress, nitrile is generally the stronger choice.
Chemical Protection and Limitations
Latex gloves provide excellent protection against a wide range of water-based chemicals and common workplace substances. They hold up well against acids like hydrochloric acid and sulfuric acid (at typical concentrations), bases like sodium hydroxide, disinfectants like formaldehyde and glutaraldehyde, and common solutions like ethylene glycol. For routine cleaning, healthcare disinfection, and handling aqueous chemical solutions, latex provides a reliable barrier.
Where latex fails, it fails quickly. Petroleum-based chemicals and organic solvents break down the rubber rapidly, sometimes in minutes. Acetone, benzene, toluene, xylene, chloroform, and diethyl ether all rate “poor” for latex resistance, meaning short exposure can cause moderate degradation or complete destruction of the glove. The same goes for many common lab solvents like methylene chloride, ethyl acetate, and trichloroethylene. If your work involves any of these chemicals, nitrile or other specialty gloves are necessary.
Latex Allergies
Natural rubber latex contains 15 known allergenic proteins, designated Hev b1 through Hev b15. In sensitive individuals, contact with these proteins triggers an immune response that ranges from mild skin irritation to life-threatening anaphylaxis. The worldwide prevalence of latex allergy sits at roughly 4.3% in the general population, but climbs to 7.2% among patients with frequent medical exposure and 9.7% among healthcare workers who handle gloves daily.
There are two distinct types of reactions. The more common one is a delayed contact dermatitis, typically caused not by the latex itself but by chemical additives used during manufacturing. It produces itchy, red, cracked skin on the hands, usually appearing hours after glove use. The more dangerous type is an immediate hypersensitivity reaction to the latex proteins themselves, which can cause hives, swelling, difficulty breathing, and in rare cases anaphylaxis within minutes of contact.
The now-banned powdered gloves were a major driver of latex sensitization in healthcare settings because the cornstarch powder absorbed latex proteins and dispersed them into the air, exposing not just the person wearing the gloves but everyone nearby. Since the powder ban, rates of new latex sensitization have declined, though the allergy remains common enough that most hospitals now stock nitrile as the default examination glove.
Latex vs. Nitrile vs. Vinyl
The three most common disposable glove materials each fill a different niche:
- Latex offers the best fit and tactile sensitivity, good chemical resistance to acids and bases, but moderate puncture resistance and the risk of allergic reactions. Best for precision medical and dental work where the user has no latex sensitivity.
- Nitrile is a synthetic rubber that provides higher puncture resistance, superior chemical resistance (especially to solvents and petroleum products), and poses no latex allergy risk. Tactile sensitivity is good but slightly below latex. It has become the most widely used medical glove material.
- Vinyl is the least expensive option, made from PVC plastic. It offers adequate protection for low-risk tasks like food service or light cleaning, but provides poor elasticity, a looser fit, and lower resistance to both punctures and chemicals. It’s not suitable for medical procedures or chemical handling.
Common Uses Beyond Healthcare
While medical and dental settings are the most visible use case, latex gloves appear across many industries. Food service workers use them for hygiene during preparation. Janitorial and housekeeping staff wear them for protection against cleaning chemicals (provided those chemicals are water-based, not solvent-based). Tattoo artists and body piercers rely on them for infection control. Home users reach for them when dyeing hair, handling raw meat, or doing messy household projects.
In all of these settings, the same principles apply: latex works well for tasks requiring dexterity and protection from water-based substances, but it should be replaced immediately if it tears, and it should never be used around organic solvents or by anyone with a known latex sensitivity.
