Re: [DCHAS-L] Glove permeation chart - not company
I addition to everyone's fantastic advice, I'd like to point out that the ACS Rubber Division's Los Angeles Rubber Group developed a chemical resistance chart for rubber materials. This chart can be useful when the subject chemical is not
listed in the manufacturer's glove chart. At a bare minimum, it will give you an indication of potential issues with various glove types.
You can find the chart at their website
https://tlargi.org/media/2019/01/TLARGI_Chemical_Resistance_Chart.pdf
Also, the chart is also available as a searchable database hosted by Dupont at

Thank you,

Thank you to everyone who provided useful answers and resources on this thread. As always, it is interesting to see how seasoned professionals take on even the most basic of questions. Also, I always enjoy reading the historical perspectives
that several members here bring to discussions like these. As you well know, newbies benefit far more from mentorship than a Google search.

Monona,
The reason why I didn't include Kimberly-Clark and certain other manufacturers was based upon my chemistry experience from high school through research at 3M.
Although it dates me, during that period, from 1961 until 1976, the use of "disposable/single use" examination gloves was not only unthinkable but also forbidden. I was acquainted
only with and used the Ansell Solvex (nitrile), neoprene and natural latex rubber gloves with caliper thickness 15mil - 22mil for any and all work on the open lab bench, in a hood/cabinet or glove box.
I may be "old fashioned" but also I have at home a supply of those type of gloves for housework. I do have a box of 4mil nitrile examination gloves but use them only for
medical and personal hygiene reasons.

John, you can add to the wonderful list of manufacturers Kimberly Clark who makes the thin examining gloves that most chemistry students and their
teachers that I see actually use. And they do have a chart as I mentioned. But they also clearly say in their brochure that those gloves should be removed and replaced if a chemical even splashes on them. Monona

Jessica,
As per the replies to your request, the consensus is that you should work with the data as "manufacturer specific" and not "generic."
Here are two helpful information sheets from W. W. Grainger, Quick Tips #166 & #191 on chemical resistant gloves.
Also, you may want to speak to someone at the Technical Service Department of any one of the following manufacturers and Grainger for help.
- Ansell
- Grainger (distributor)
- Magid Glove & Safety (manufacturer/distributor)
- MAPA
- North by Honeywell
- SHOWA

you also have to take into account the glove thickness, which could vary by brand. Some nitrile gloves are 4 mm, others 8 mm...
I don't think I would want a generic chart, so much depends on the mfg. And they have quite a bit of incentive to get it right...$$$$$

Caution: If you are going to be citing the NIOSH Recommendations for Chemical Protective Clothing for glove guidance - check when it was published, it is severely dated.
Monona is right, look at the individual glove manufacturer for testing permeation and degradation information. If you do a Google search, you'll end up with generic information
that will be unreliable - depending upon which glove has been specified.
Suppliers and Google will provide generic "data" but nothing I would rely upon when you really need to confirm adequate protection.
It's late and I can't remember the name of the organic chemist who started the testing work at Ansell. He developed the first spreadsheet, which later turned into their database.
When I ran into a new molecule that was going to be tested for toxicity as an investigational new drug, if he could not refer to a very close analog to provide protection, I could send him a sample and he would test to provide a recommendation. It depends
upon what you are trying to protect against. Is a generic, possibly diluted level of protection adequate or are you trying to protect from a true hazard?
