You made the switch from latex. You heard about latex allergies, so you moved to nitrile. But your hands are still red, dry, cracked, and uncomfortable after a long day. Sound familiar?
You’re not alone. Many dental professionals assume they’re allergic to nitrile itself. But in reality, the irritation often comes from the chemical accelerators used to manufacture the glove, not the nitrile base. We'll explain the difference, show you what “accelerator-free” really means, and give you a clear plan to try gloves that finally let your hands breathe easy.
It’s Not the Nitrile. It’s the Accelerators.
Let's clear up two immune reactions that often get confused.
- Type I (immediate latex allergy): A true allergic reaction to latex proteins. Symptoms can include hives, itching, swelling, or even anaphylaxis within minutes of exposure. If you had a true latex allergy, switching to nitrile or neoprene typically eliminates exposure to latex proteins.
- Type IV (delayed hypersensitivity / contact dermatitis): This is a reaction to chemical additives, most often accelerators like thiurams, dithiocarbamates, and mercaptobenzothiazoles. Symptoms take hours or even a day or two to appear: red, scaly, itchy, cracked skin on the back of your hands and wrists. It looks and feels like eczema.
If you switched from latex and your symptoms continued (or even appeared for the first time), you may be dealing with Type IV allergic contact dermatitis related to chemical accelerators. No guesswork needed. You can move to gloves that skip the problem chemicals entirely.
What Does “Accelerator-Free” Actually Mean?
During nitrile glove manufacturing, chemical accelerators are added to speed up the vulcanization process, the step that turns liquid nitrile into the strong, elastic film you stretch over your hand. Without accelerators, typical nitrile would take too long to cure and wouldn’t perform well.
But advanced formulations now exist that eliminate traditional accelerators. Instead, they use a cross-linking technology that bonds the nitrile polymer without the harsh chemicals linked to skin sensitization.
The result is a glove that feels and performs like a premium nitrile exam glove, without the chemical residue that triggers dermatitis.
Remember, “accelerator-free” doesn’t mean “chemical-free.” It means the formulation avoids the specific accelerators known to cause Type IV reactions. A true accelerator-free glove should come with documentation you can review.
Who Makes Accelerator-Free Gloves Worth Trying?
Several manufacturers have stepped up to solve this exact problem. Here are the names you’ll see most often, and what to know about each.
- Ansell: Their MICROFLEX® Freeform® SE and LifeStar™ AF line are well-known accelerator-free offerings with strong tactile sensitivity. A solid starting point if you want a mainstream option.
- Tronex: Their S600 accelerator-free glove is a popular choice in dental, praised for its soft feel and good donning characteristics.
- HandPRO (Hourglass Industries): HandPRO offers accelerator-free grades used in sterile and cleanroom environments; their dental-focused lines are gaining traction.
- Clinical Supply Company (Posi-Shield® Advanced & Posi-Prene®): Our Posi-Shield Advanced line is proudly accelerator-free, with an optional aloe vera inner coating that soothes and moisturizes skin throughout the day. If dryness and cracking are your main complaints, the aloe version can make a world of difference. Our Posi-Prene family also includes non-latex glove options built for dental professionals who want unmatched comfort and protection from a family-owned company that lives in this industry.
We’ll be the first to tell you: don’t just take our word for it. Test them yourself.
Your Practical, No-Stress Evaluation Plan
Switching gloves across your operatories doesn’t have to be a leap of faith. Follow this simple roadmap to find what works for your team.
- Request Samples First. Every reputable supplier will send free boxes or pairs for evaluation. Ask for at least one box in the sizes most of your team wears. Wear them for a full clinical day, don’t just slip one on and pull it off. Pay attention to:
- Fit (is it snug but not restrictive?)
- Donning (does it require more effort, especially when hands are slightly damp?)
- Tactile sensitivity (can you feel calculus?)
- Dryness level at the end of the day
- If you’re trying Clinical Supply Company’s Posi-Shield Advanced, request both the standard and the aloe-coated versions. The aloe coating changes the feel inside the glove dramatically, and many providers say it’s the first time their skin stays comfortable through back-to-back patients.
- Ask for the Chemistry Documentation. A legitimate accelerator-free manufacturer will provide:
- A product data sheet or technical bulletin listing the chemical composition and confirming that no thiurams, dithiocarbamates, or MBT are present.
- Any relevant product documentation or third-party testing for skin sensitization.
- A statement of compliance with ASTM D3578 and ISO 11193 standards.
- If a company hesitates or gives you vague marketing language, treat that as a red flag. You deserve transparency.
- Run a Small Team Trial. Pick two or three staff members with the most sensitive skin. Have them use the new glove exclusively for two weeks. No switching back and forth. Document any redness, itching, or cracking. Just as important, note improvements in comfort. Many teams find that after one trial period, the whole office adopts the glove because the difference is so clear.
- Compare Cost Per Use, Not Just Box Price. Accelerator-free gloves can cost a bit more per box. But factor in:
- Reduced use of barrier creams and hand lotions.
- Fewer sick days or accommodations for damaged skin.
- Higher staff satisfaction and retention.
When you calculate the total cost of skin misery, the “premium” glove often saves money.
Why We Care More Than Most
At Clinical Supply Company, we’re a family-owned business with decades in the dental world. We’ve seen too many hygienists and dentists suffer needlessly because no one explained that accelerators, not nitrile, were the true culprit. That’s why we invested in glove technologies designed to improve comfort and performance for dental professionals, and why we’ll always shoot you straight about what our gloves can and cannot do.
We don’t want you to guess. We want you to feel the difference, review the proof, and join a community of providers who finally have happy hands again.
Ready to Try Accelerator-Free Gloves Without the Guesswork?
Request samples of our Posi-Shield Advanced (with or without the aloe coating) directly from Clinical Supply Company. Our team will walk you through the documentation, answer your technical questions, and ship out trial gloves so you can test them in your own practice, on your own terms.
Your hands do too much good to be in pain at the end of each day. Let’s fix that, together.
