RSDL – Reactive Skin Decontamination Lotion Guide

This guide has been updated to include updated news on civilian purchases no longer available and the newly awarded 2023 DoD contract.

I got to use some cutting-edge gear while teaching military members how to avoid and deal with chemical, biological, and radiological contamination. We had laser and spectrometry-equipped tools that totaled millions of dollars to help us identify threats. We wore protective suits that cost thousands of dollars while exposed to actual chemical threats.

Then, one day in late 2009, they brought us RSDL. We had all of this high-tech gear and protection for training and we get ‘pouches of goo’ for decontamination. Well, it turns out that it worked pretty darn well and didn’t cost thousands of dollars when it came time to re-order. What is RSDL? We’ll get to that, how it works, and a few experiences I’ve had with it in this post.

What is RSDL?

RSDL is an acronym for Reactive Skin Decontamination Lotion which comes in pouch kits for decontaminating direct skin exposure to many types of chemical weapons. It is a relatively new decontamination kit for the military, and a brand new kit as far as general purchase.

When you tear open the pouch, you find a gel-filled sponge that absorbs and neutralizes chemicals. It is meant to be applied to bare skin but can be used on equipment and vehicles as well. The gel has the consistency of honey, so it gets between the fingers pretty good. RSDL replaced the M291 decontamination kit, which is a small activated charcoal pad meant to be worn on the fingers. The large activated charcoal mitt (M295) is still in service.

The lotion is considered an upgrade because it is easily washable, less toxic, and is an FDA-approved medical device. Users claim, and I can tell you, that it is easier to apply than charcoal kits.


How Does the RSDL Pad Work?

The RSDL pad is a sponge filled with lotion that neutralizes chemical warfare agents and weaponized toxins, and then allows for easy removal from skin. The active ingredient in the lotion is proven in lab tests to neutralize these chemical agents starting within two minutes:

  • Vx
  • Sarin
  • Mustard (HD)
  • Soman
  • Tabun
  • T2 Toxin

RSDL is very simple to use. First you identify contamination. If you do not know how to identify signs of chemical contamination, we’ve covered this topic before. Next, open the packet at one of the notches to remove the coated sponge. Next, wipe the contaminated spot by scrubbing with the RSDL sponge.  Finally, rinse the lotion off when you are in a non-contaminated area.  

Depending on where you get your RSDL kit, it may come with a training sponge in a blue pouch. If it does, I highly recommend that you use the training device so you know how to quickly open, apply, and flush the kit. It will help you know about how much coverage you can get out of one pouch and get used to the consistency of the lotion in the sponge.

Why Have RSDL?

RSDL, while a niche preparedness tool, is one of the few tools you can own that can neutralize a chemical warfare agent. There are many ways to deal with radiation hazards and biological attacks, but chemical weapons pose a unique threat. Many have talked about the importance of recognizing chemical threats:

  • “The threat of chemical terrorism must now be regarded as very real, and measures to address it must be assigned much higher priority” – Organization for the Prohibition of Chemical Weapons (OPCW) Director General
  • “What we saw was total death. Nothing was alive. All of the animals had come out of their holes to die. Dead rabbits, moles, rats, and mice were everywhere. […] the trenches were empty but in a half mile, the bodies of French soldiers were everywhere. […] You could see where men had clawed at their faces, and throats, trying to get a breath. Some had shot themselves. The horses, still in the stables, cows, chickens, everything; all were dead. Everything, even the insects were dead.” – Willi Siebert, German soldier that witnessed the first ever chlorine gas attack during World War I

We give chemical attacks a low-risk score in our TrueRisk index, but it is important to differentiate between low-risk and no-risk. The TrueRisk index is a tool to prioritize the risks; not to ignore them.

How to Buy RSDL

**2023 Update** RSDL is no longer for sale for civilian use, despite DoD awarding a $300M+ contract to Emergent BioSolutions.

While the main vendor for RSDL (Emergent BioSolutions lab) is no longer selling direct and is not listing any product on their Amazon store, you may be able to source RSDL through military surplus sources.

A Few Words of Caution

There are a few things you should be mindful of with RSDL:

  • Do not use prior to chemical exposure (it doesn’t work that way).
  • Avoid unnecessary exposure. Do not leave on skin for excessive periods. Use training RSDL for training and demonstration purposes.
  • Do not eat RSDL or use RSDL on your eyes.
  • Do not store or combine with oxidizing chemicals, such as bleach. A chemical reaction can occur causing a fire hazard.

Most of these warnings may seem like common sense- but people can make bad decisions when presented with threats that they do not encounter often. That is just another reason why training for all situations makes sense.


The Material Safety Data Sheet can break down even further what you need to know about the Reactive Skin Decontamination Lotion kit: RSDL MSDS 2006

The RSDL Company and Manufacturer

E-Z-EM, Inc was the first manufacturer awarded with the RSDL contract by the Department of Home Security (DHS) in 2007. Emergent BioSolutions acquired them in 2013 which added RSDL to their portfolio of products.

In late 2017, Emergent BioSolutions made RSDL available to the civilian population through industrial supply stores and online. When we checked in 2023, they were no longer listed on their site and removed from their Amazon storefront.

Also in 2023, Emergent BioSolutions was awarded a $379M supply agreement for the DoD.

The Final Word

RSDL made our life easier in the military, and it makes a great addition to any specialized decontamination kit. The lotion kit is easy to use, works well, and has a long shelf life. RSDL is a solid decontamination solution that you should consider adding to a specialized chemical kit for additional protection.

Like most specialized kits, the chance that you will use them is low but the equipment is simply irreplaceable in the event that you need it. Know the risks in your area, and get the proper equipment to protect yourself in case SHTF.  

Keep exploring, stay prepared, and be safe.

One thought on “RSDL – Reactive Skin Decontamination Lotion Guide

  • thank you for the facts and simple explanations between the types of personal decontamination materials i found that portion very refreshing for someone to drop the dime and list what each of the publicly available options were, however your opinions need to be listed separately from the facts as do the historical excerpts however relevant they may or may not be if you changed this single thing about the article id give it a 10 for usefulness to the new and uninitiated as this has proven useful to me and several other people in the circles i travel in… again im not trying to argue or denigrate just how the information was presented is my personal issue
