This page describes products and general use; it is not medical advice.
Who this is for: clinic staff, buyers and students who need to tell apart three things that are often blurred together: gloves made of natural rubber latex, gloves sold as latex-free, and gloves sold as accelerator-free. After reading, you should be able to say which glove materials FDA names as alternatives to natural rubber latex, what FDA labeling rules do and do not cover, and why “latex-free” and “accelerator-free” are different claims.
What are latex allergy gloves?
“Latex allergy gloves” is a search phrase, not a product category. It usually means medical gloves made from a material other than natural rubber latex. FDA regulates medical gloves as Class I reserved medical devices that require a 510(k) premarket notification, and notes that some people are allergic to the natural rubber latex used in some medical gloves. FDA names polyvinyl chloride (PVC), nitrile and polyurethane among the alternative synthetic materials. Typical users are clinicians, dental and laboratory staff, and procurement teams who stock examination gloves.
Two different glove allergen sources
A rubber glove can contain two separate things that people discuss under “allergy”. They are not the same, and a glove can be free of one and not the other.
Natural rubber latex
This is the material itself. FDA’s rule at 21 CFR 801.437 covers devices that are composed of or contain natural rubber and that contact humans, including synthetic latex or synthetic rubber that contains natural rubber in its formulation. Such labeling must carry the statement “Caution: This Product Contains Natural Rubber Latex Which May Cause Allergic Reactions.” in bold on the principal display panel and on the outside and immediate packages. The same section says this labeling shall not contain the term “hypoallergenic”.
Rubber accelerators
Accelerators are chemicals used as vulcanizers in making rubber items, and a 2025 systematic review and meta-analysis in Contact Dermatitis (106 studies, 826,543 people patch tested between 1984 and 2023) describes them as chemicals that may cause contact allergy. Pooled contact-allergy prevalence among the patch-tested patients was 2.55% for thiuram mix, 0.86% for mercapto mix, 0.83% for mercaptobenzothiazole and 3.96% for carba mix, with a decline after 2000 for all three baseline accelerator groups. These are figures for people referred for patch testing, not for the general population, and they are not a statement about any specific glove. The authors called for improved labelling and reduced use of high-risk accelerators.
The two sources are separate in the literature too. An Australian occupational dermatology clinic review of 685 healthcare workers (1993 to 2014) reported natural rubber latex allergy in 13.0% and listed rubber glove chemicals (thiuram mix and tetraethylthiuram disulfide) among the major causes of allergic contact dermatitis.
Types and materials
FDA product classification groups examination gloves under 21 CFR 880.6250; every code below is Class I (openFDA classification database, checked 2026-10-30).
| Glove material | FDA product code and name | Key difference |
|---|---|---|
| Natural rubber latex | LYY, Latex Patient Examination Glove | Falls under the 21 CFR 801.437 caution statement and the ban on “hypoallergenic” in that labeling |
| Polyvinyl chloride (vinyl) | LYZ, Vinyl Patient Examination Glove | PVC is one of the alternatives to natural rubber latex that FDA names |
| Other polymers, including nitrile and polyurethane | LZA, Polymer Patient Examination Glove | FDA names nitrile and polyurethane as alternatives to natural rubber latex |
| Polychloroprene | OPC, Powder-Free Polychloroprene Patient Examination Glove | Has its own product code, listed as powder-free |
For material-by-material detail, see nitrile gloves, vinyl gloves, chloroprene gloves, polyisoprene, and the side-by-side nitrile vs latex vs vinyl comparison.
What does “accelerator-free” mean?
Accelerator-free is a manufacturer claim. Neither FDA’s medical gloves page nor 21 CFR 801.437 defines the term or sets a rule for accelerator content. The regulation’s mandatory caution and the “hypoallergenic” restriction concern natural rubber latex. FDA does require manufacturers to identify the materials used to make medical gloves on the package labeling, so the material is the part of the label you can anchor on; any statement about accelerators needs the manufacturer’s own specification or instructions for use.
It follows from the scope of 21 CFR 801.437 that a glove made from natural rubber latex is a natural rubber latex glove whether or not it is marketed as accelerator-free, so the two claims should be read independently.
What FDA labeling does and does not tell you
- FDA requires the materials used to make the gloves to be identified on the package labeling.
- Natural rubber devices carry the 21 CFR 801.437 caution statement.
- That section has no “latex free” provision, and the wording question is covered in not made with natural rubber latex.
- FDA issued a final rule banning powdered gloves on December 19, 2016.
- Nothing in the FDA glove page or the regulation covers accelerator content.
Safe use and handling basics
General points only. The manufacturer’s instructions for use and the carton labeling state the glove material and any stated limits, and the material named on the package is the item to compare against a facility’s own glove specification. For the natural rubber side, see what a latex glove is.
Common mistakes
- Treating “latex-free” and “accelerator-free” as the same claim. They address different things.
- Reading “hypoallergenic” as a regulatory category. In natural rubber latex labeling, 21 CFR 801.437 prohibits the term.
- Assuming a prevalence figure from patch-tested patients describes the general population or a specific glove.
- Relying on the box front instead of the material statement required on the package labeling.
FAQ
What are accelerator-free gloves?
Gloves marketed by the manufacturer as made without rubber-processing accelerator chemicals. The term is not defined in FDA’s gloves page or in 21 CFR 801.437, so the manufacturer’s specification is the source for what it means.
Are latex-free gloves the same as accelerator-free gloves?
No. Latex-free refers to the absence of natural rubber latex; accelerators are a separate group of chemicals used as vulcanizers in making rubber items.
Which materials does FDA name as alternatives to natural rubber latex?
Polyvinyl chloride (PVC), nitrile and polyurethane, among other synthetic materials.
