In , the global market for nitrile gloves was around $8.76 billion. People are opting to protect their hands with these gloves. The demand increased during the COVID-19 pandemic.

Let's look closely at the nitrile glove chemical resistance. Which chemicals can you protect yourself against?

Are Nitrile Gloves Chemical Resistant?

Yes. Nitrile gloves are among the best chemical-resistant gloves in the glove market today. These nitrile gloves are resistant to some chemicals for shorter periods. Depending on the chemical, you may be able to use it for two hours before it reaches its breakthrough time.

If you're handling harsh chemicals, dispose of the gloves after brief contact of 15 minutes. Ensure proper glove removal and discard your gloves if they become soiled or when you notice a tear or puncture to prevent chemicals from penetrating inside.

One of the features that makes these gloves resistant to a variety of chemicals is the synthetic rubber material. The synthetic rubber is an artificial elastomer synthesized from petroleum byproducts. It has a variety of properties that make it useful for different purposes. For example, synthetic rubber is often used in tires because it is durable and highly resistant to heat.

Since nitrile gloves are made of synthetic rubber, they have become famous in many industries, including healthcare, automotive, and food service.

Nitrile gloves used to be blue. Now you can choose from a wide range of colors, such as pink, purple, black, white, orange, and green.

These gloves are available in various sizes and thicknesses. Of course, choosing one that matches your industry is the best. Mechanics prefer black nitrile gloves since they can hide grease, grime, and dirt.

Evaluation Criteria for Nitrile Gloves Chemical Resistance

You can grade nitrile glove chemical resistance based on these three criteria:

• Degradation: This is when the gloves start to deteriorate, changing their physical properties when they come into contact with chemicals. You can easily note that your glove has started to degrade when you see signs of cracking, swelling, shrinking, or softening.
• Breakthrough time: The total time it takes for chemicals exposed to the outside of the glove to permeate inside, offering no protection.
• Permeation rate: The rate at which chemicals flow into the glove once it reaches its breakthrough time.

It's good to note that temperatures, duration, and movement can affect the above factors in disposable nitrile gloves or any other glove on the market.

Besides nitrile gloves being chemical resistant, they also have the following outstanding features:

• Tears and punctures are easily evident
• Good choice for chemical and petroleum applications
• Offers great tear, abrasion, and puncture resistance
• Higher durability
• Powder-free for lower risk of allergies
• Textured fingertips for increased tactile sensitivity
• Ambidextrous design
• An alternative for those with a latex allergy

What Chemicals Are Nitrile Gloves Resistant To?

Nitrile gloves are generally safe for use with most chemicals. Some substances can cause them to degrade more easily and quickly. Exposing nitrile gloves to chemicals for an extended period causes them to degrade more rapidly, reducing their protection. Some chemicals you can use with nitrile gloves for excellent protection include the following:

• Weak acids
• Weak caustics
• Fuels
• Greases
• Vegetable oils
• Petroleum products
• Household detergents

Nitrile gloves offer poor protection to:

• Ketones
• Some alcohols
• Esters
• Strong acids

Avoid using nitrile gloves on the following chemicals:

• Acetone
• Sulfuric acid 95%
• Tetrahydrofuran (THF)
• Nitric acid 70%
• Benzaldehyde
• Ethyl acetate

The following table provides information on some chemicals you can use with nitrile gloves and the ones you can use alternatives. It's important to note that testing is done under perfect conditions. Consideration has not been done under real situations where temperature, chemical combinations, or duration come into play.

It's crucial to pick nitrile gloves depending on the chemicals you're exposed to. The gloves are designed for different purposes. If you're in the industrial sector working on automobiles, choose a glove that can withstand chemicals derived from petroleum, like grease and oil. Get exam-grade gloves if you work in the healthcare, cosmetology, or pharmaceutical sectors.

Ensure that the glove thickness is correct depending on the job you want to use them for. Nail technicians' gloves should allow for better dexterity and flexibility and maintain a sense of touch. Industrial jobs will need a glove thickness that can provide superior protection with a higher rate of puncture resistance.

Another crucial factor in choosing nitrile chemical resistant gloves is size. You'll want to choose a size that fits comfortably on your hands. Besides comfortability, the glove size can determine chemical resistance. Wearing a small size makes the glove overstretch and less protective.

Are Nitrile Gloves Acid Resistant?

Yes, but it depends on the type of acid. Nitrile gloves are synthetic rubber resistant to many chemicals, including some acids. Nitrile gloves offer limited chemical protection in some strong acids, such as hydrofluoric acid (HF) ≥30%,which breaks down the glove material upon contact.

In cases where you use chemicals with higher permeation, you can consider double gloving. It's good to note that nitrile gloves' acid resistance is the best when compared to standard nitrile gloves.

Can Nitrile Gloves Protect Against All Chemicals?

No. Nitrile gloves are not resistant to all chemicals. It's good to note that no glove can protect you against all substances. Most nitrile gloves are protective against a wide range of chemicals, but there are some exceptions.

Some fluids can be chemical hazards, like acetone, which can penetrate nitrile gloves. Choosing suitable gloves for the job is essential. Some gloves are also more resistant to tearing and punctures than others. It's important to choose a glove that will be durable enough for the task at hand.

How Thick Should Nitrile Chemical Resistant Gloves Be?

The thickness you choose for your nitrile gloves depends on the application. If you're using gloves for light chemical resistance, you might want a thinner glove. If you're using them for heavy chemical resistance, you might want a thicker glove.

Most disposable nitrile gloves' thickness ranges from 4 mils to 10 mils. The most common glove thickness is between 6 mils and 8 mils. Anything above 8 mils is considered heavy duty.

Where Can I Use Nitrile Gloves?

Nitrile gloves are common in healthcare facilities as they are stronger at providing a barrier against blood-borne pathogens. Disposable gloves can also help prevent cross-contamination. Besides using nitrile gloves in healthcare facilities, you can use them in other industries such as food service, cleaning, cosmetology, painting, and mechanical.

Protect Your Hands With the Right Disposable Nitrile Gloves

Our hands are the most important tools for performing many tasks in our homes and workplaces. You can use nitrile chemical resistant gloves to provide maximum protection to your hands if you deal with hazardous chemicals. Some chemicals can permeate nitrile gloves. So ensure you understand substances that cannot permeate nitrile gloves.

Given that food and medical care are two universal needs, it is also important to uphold safety and hygiene standards.

One of the various safety measures observed, that of medical nitrile gloves, needs no introduction; they have become a critical enabler towards enhancing healthcare delivery as well as ensuring food hygiene. They not only act as a shield from infectious organisms but also adhere to the prescribed safety standards. 

This article describes the functions, special qualities, strengths, and applications of food-safe nitrile gloves. 

What Are Medical Nitrile Gloves?

Medical nitrile gloves are medical-grade disposable gloves made from a synthetic rubber material called nitrile. The design of this material aims to offer a more robust protective layer compared to standard latex and vinyl gloves.

Advantages Over Latex and Vinyl

There are concerns regarding the composition of the primary ingredient in nitrile latex gloves. While they do contain formaldehyde, they outperform latex in terms of strength and protection, and more importantly, they possess anti-bacterial properties. 

A research study indicates that nitrile gloves can withstand up to 3 times more puncture abuse as compared to vinyl gloves. Nitrile, additionally, is resistant to a wide range of chemicals, which is important for applications that involve medical and food handling.

Common Uses in Medical and Food Industries

The medical industry commonly uses nitrile gloves during surgical procedures, examinations, and patient care provision. Food service professionals use nitrile gloves during food preparation, serving, and handling to improve hygiene and minimize the risk of food product contamination. 

Key Features of Medical Nitrile Gloves

Check out the key features of medical nitrile gloves below: 

• Durability and Protection

The key factor that nitrile gloves offer users is the inherent durability of the medical nitrile gloves. The high puncture and chemical resistivity, respectively, of the gloves, in turn, protects healthcare professionals and food handlers from any exposure to hazardous substances. 

Several studies have determined that nitrile gloves do have the ability to resist many different chemicals, including oils, solvents, and some acids, which would render the gloves useful for different purposes. 

• Allergy-Friendly

Another significant drawback of latex gloves is that many users may experience allergic reactions to them, which is concerning for the medical field as it exposes many individuals to cross-contamination risks. 

Research indicates that between 1 and 7.6% of healthcare workers suffer from latex allergy, which could potentially cause disruptions for users and jeopardize the workplace's well-being. 

Nitrile gloves have shown to be the best option as they do not contain any latex, enabling professionals to work without the worry of suffering from allergic reactions. 

• Powder Free vs. Powdered Gloves

Despite the widespread acceptance of powdered gloves in various professions, the medical and culinary fields now widely use powder-free nitrile gloves. However, professionals in the organ, eye, and tissue industries assert that the powder in these gloves could potentially cause contamination and irritation in hypersensitive individuals. 

The FDA has also documented that the application of powdered gloves has been associated with toxicity, which has driven many institutions to adopt powder-free gloves.

Powder-free nitrile gloves have been a hot focus in the market due to their various advantages. People who tend to be allergic to powders commonly used in other glove types can wear these gloves, designed to reduce skin irritation and increase user comfort. 

• Reduced Skin Irritation

People who wear gloves may, at some point, experience irritation from powdered gloves made of latex or nitrile material. Despite the powder's intended solution, it often exacerbates multiple issues, such as irritation and dryness. 

Statistics show that a greater percentage of the population, around 10 percent, are allergic to latex. These allergies have, in some instances, elevated the demand for powder-free gloves.

· Compatibility with Sterile Environments

Clean environments are critical within medical and laboratory environments. The chances of such a glove bearing any contaminated powdered substance by using powder-free nitrile gloves are nonexistent.

 Furthermore, the risk of powder particles interfering with clean procedures is also associated with these gloves, thus providing reassurance to users. 

Risks Associated with Powdered Gloves

Powdered gloves may seem useful, but in the real world of application, they present several major risks. The powder is an allergen irritant and can cause a range of different reactions, from skin rashes to breathing problems. 

This type of protection also increases the contamination risk, for example, in surgery or other situations that are considered sterile or aseptic or where even a small disturbance can cause disaster. 

Food Safe Nitrile Gloves

Food safety, cleanliness, and safety are of utmost importance and are never subject to debate. Strict guidelines govern the production and testing of food-grade contact medical nitrile gloves, ensuring their suitability for food handling. 

Certifications and Standards

A strong indicator that the gloves are suitable for use in the restaurant or food industry is the FDA (Food and Drug Administration) approval assigned for food gauge Nitrile gloves. This certification ensures that the gloves maintain a high degree of safety after undergoing specific tests.

Based on the document provided by them, PPE usage by employees of food service establishments is a must, which, as stated in the article, takes such stringent measures into account and is important to comply with.

Differences Between Food Safe and Medical Grade Nitrile Gloves

Although both have similar applications in terms of protection, the most important aspect in which these two differ is the purpose: medical use or food handling. 

Medical grade applies to the use of medical nitrile gloves in healthcare settings, ensuring sterility. Such gloves are manufactured of food contact-grade material and are put on with the main aim of providing protection rather than during food contact to avoid contaminations. 

Common Applications in Food Handling and Processing

Food-grade nitrile gloves serve multiple purposes in various scenarios: 

• Food Preparation: Used by chefs and other kitchen staff to prevent loss of hygiene when making the food.
• Food Processing: Nitrile gloves are worn by workers in processing factories to avoid cross-contamination.
• Handling Ready-to-Eat Foods: With these gloves, food can be put in direct contact with the clients, and therefore, safety and cleanliness are guaranteed.
