The Microflex Supreno SE is a fully accelerator-free nitrile examination glove—no thiurams, no carbamates, no mercaptobenzothiazoles—engineered specifically for healthcare workers with confirmed Type IV contact dermatitis who cannot wear standard nitrile gloves without developing skin reactions.
Why This Glove Stands Out
Published · Last updated
Accelerator-free is categorically different from accelerator-reduced. The Ansell SU-690 (also in this collection) reduces accelerators—it does not eliminate them. The Supreno SE uses an accelerator-free vulcanization process that produces a finished nitrile glove with zero detectable accelerator content. For users with confirmed Type IV allergy, this is the difference between an acceptable solution and the correct solution.
Performance and Fit
At approximately 7 mil, the Supreno SE is the heaviest exam-rated glove in this collection. That gauge provides excellent puncture resistance—appropriate for clinical environments where sharps, glass, and metal instruments create puncture hazards—while the exam-grade AQL validates its barrier performance for medical use. The purple/violet color is shared with chemo-rated gloves in many facilities; verify your facility's color protocol to prevent confusion.
The accelerator-free formulation requires a different vulcanization chemistry than standard nitrile—resulting in a glove that may feel slightly different from standard nitrile in terms of elasticity and snap-back. Most users with Type IV sensitivity find any perceptible difference in glove feel is acceptable compared to the alternative of continuing to develop dermatitis from standard gloves. Powder-free construction eliminates the separate latex protein / talc sensitization pathway.
It is worth being precise about what accelerator-free does and does not solve. It addresses Type IV allergic contact dermatitis—a delayed, cell-mediated reaction to residual rubber accelerators—by removing the trigger from the glove itself. It does not address irritant contact dermatitis caused by frequent hand washing, occlusion, and sweat, nor a Type I latex protein allergy, which nitrile already avoids by containing no natural rubber latex. For a worker whose patch test confirms accelerator sensitivity, switching to a zero-accelerator glove is the targeted fix; for a worker whose rash is irritant-driven, glove chemistry is only part of a skin-care and glove-rotation program. Matching the glove to the actual diagnosis is the difference between solving the problem and spending a premium without resolving the reaction.
Durability and Chemical Protection
EN 374 and EN 455 dual-certification validates both chemical protection and medical exam barrier compliance. At 7 mil with EN 374 chemical ratings, the Supreno SE also provides more chemical resistance than standard thin exam gloves—making it appropriate for environments with both accelerator-sensitivity requirements and chemical handling tasks, without needing two separate glove products.
Total Cost and Procurement Fit
Per glove, the Supreno SE costs more than commodity nitrile, and at 25 pairs in a 50-count box the unit economics look expensive next to a 100- or 200-count value box. But the relevant comparison is not box price against box price; it is the cost of the right glove against the cost of an unmanaged dermatitis problem—lost productivity, accommodation requests, repeat clinic visits, and the churn of cycling a sensitized worker through gloves that keep failing them. Deployed correctly—issued to the specific workers with confirmed accelerator sensitivity rather than poured across an entire facility—the premium is contained and justified. Some buyers keep a commodity nitrile as the house glove and stock the Supreno SE as the named-allergy alternative, which keeps overall spend down while still giving occupational health a documented, accelerator-free option to point to. The published technical data sheet supports that documentation trail for procurement and regulatory files.
Pros and Cons
Pros
- Fully accelerator-free—zero thiurams, carbamates, or MBT—eliminating Type IV sensitization risk entirely
- ~7 mil heavier gauge adds puncture resistance beyond standard exam gloves
- EN 374 chemical protection plus EN 455 medical exam certification in one glove
- Powder-free eliminates the separate talc contamination pathway
Cons
- 50 per box at premium price—accelerator-free formulation commands a higher manufacturing cost
- Purple color may conflict with chemo-rated purple protocols in some facilities
Who Should Buy This Glove
Order for healthcare workers, dental professionals, and lab technicians with confirmed Type IV contact dermatitis from accelerators who cannot tolerate standard or reduced-accelerator nitrile. Also appropriate as a facility-wide premium option for environments with a history of glove-related dermatitis complaints.
Who Should Skip It
Skip if you have no confirmed accelerator sensitivity—the premium pricing is not justified for users who tolerate standard or reduced-accelerator nitrile. For general exam use at lower cost, MedPride, Curad, or Medline Restore are more economical.
How It Compares
The Ansell SU-690 (violet, 3.9 mil, reduced-accelerator) is the step below for users with sensitivity who are not confirmed allergic. The Kimtech Purple (purple, 5.9 mil, USP 800) handles the chemo-rated niche without accelerator-free formulation. The Kimtech Polaris (EN 374, 6 mil) handles lab chemical use without accelerator-free status.

Frequently Asked Questions
What does 'accelerator-free' mean for nitrile gloves?
Standard nitrile gloves use chemical accelerators (thiurams, carbamates, mercaptobenzothiazoles) in vulcanization. Accelerator-free gloves use alternative vulcanization chemistry that produces no residual accelerator content—eliminating the Type IV dermatitis trigger for sensitized users.
What is Type IV contact dermatitis?
A delayed hypersensitivity reaction to chemical accelerators in gloves. Symptoms (redness, itching, rash on glove-covered hands) appear 12–48 hours after contact. Unlike Type I latex allergy, it is not immediately life-threatening but causes significant occupational discomfort and can progress with continued exposure.
How is this different from the Ansell SU-690?
The SU-690 is reduced-accelerator—lower concentrations than standard nitrile, but not zero. The Supreno SE is zero-accelerator. For users with confirmed Type IV allergy, zero-accelerator is the clinically indicated choice.
How do I confirm I have Type IV contact dermatitis?
Consult an occupational medicine physician or dermatologist. Patch testing with a panel of rubber chemical accelerators is the standard diagnostic method. Self-diagnosis is not reliable—professional testing confirms which accelerators are causing the reaction.
Are these latex-free?
Yes. 100% nitrile—no natural rubber latex. Safe for Type I latex allergy as well.
Is the Supreno SE rated for chemo drug handling?
EN 374 chemical protection covers many chemical agents. For formal USP 800 compliance in pharmacy compounding specifically, verify against current USP 800 glove requirements—the Kimtech Purple is specifically marketed with USP 800 rating.
Why is the gauge approximately 7 mil for an exam glove?
The accelerator-free vulcanization process and EN 374 chemical protection requirements are more easily achieved at heavier gauge. The 7 mil spec also provides better puncture resistance for clinical environments with sharps and instrument hazards.
How many pairs per box?
25 pairs in a 50-count box.
What sizes are available?
XS through XL. Verify sizing before bulk ordering.
What is the shelf life?
Three to five years in cool, dry storage.
Can the Supreno SE be used in food production?
Yes—accelerator-free, powder-free, latex-free nitrile is appropriate for food contact. The purple color is unusual in food-service settings; verify color acceptance with your authority.
Does accelerator-free affect glove feel?
Slightly. Accelerator-free vulcanization produces a glove with somewhat different elasticity characteristics than standard nitrile. Most users with Type IV dermatitis find any perceptible difference acceptable compared to continued skin reactions from standard gloves.
Is the Supreno SE sterile?
Non-sterile examination gloves. Sterile versions require separate packaging and sterilization validation.
Can I use Supreno SE for dental procedures?
Yes. 7 mil is heavier than typical dental exam preferences, but appropriate for procedures where sharps protection is valued. For maximum tactile sensitivity, a thinner exam glove is preferred.
What documentation is available for procurement?
Ansell Microflex publishes technical data sheets for the Supreno SE confirming accelerator-free formulation, EN 374 test results, and EN 455 compliance—available for regulatory and procurement documentation purposes.
Does accelerator-free also help with irritant contact dermatitis?
Not directly. Accelerator-free formulation targets Type IV allergic contact dermatitis by removing the chemical trigger. Irritant contact dermatitis from frequent washing, sweat, and occlusion is a different mechanism and needs a skin-care and glove-rotation program rather than a chemistry change. Confirm which you have with patch testing before choosing.
Why is the Supreno SE purple, and does the color matter?
The purple/violet color is a manufacturer convention. It matters operationally because purple is also used in many facilities for chemo-rated gloves, so verify your facility's color protocol to avoid confusion at the point of use. The color has no bearing on the accelerator-free protection itself.
The Bottom Line
Microflex Supreno SE is the correct prescription for Type IV accelerator contact dermatitis—the only glove in this collection with zero accelerator content. It is priced as a specialty product and should be positioned as such: the right tool for a specific clinical and occupational health problem.
