Is Epoxy Resin Toxic?

When the epoxy resin cures completely, it’s considered safe for various applications. Some brands are even ideal for use on food preparation surfaces and tabletop making.

Despite this, specialists advise users to take safety precautions when handling epoxy. You should wear a respirator mask and a pair of gloves. For this reason, one may wonder; is epoxy resin toxic? Well, let’s find out!

Is Epoxy Toxic to Human and Animal?

In general, pure epoxy is non-toxic, both to humans and animals. Besides, the risk associated with its ingestion is deemed to be very small. Nonetheless, most chemical products in the market today have some level of toxicity. And epoxy is not an exception!

For instance, some epoxy resins may contain epichlorohydrin. This is a certain contaminant that can cause skin cancer in lab animals. Epichlorohydrin can cause cancer in people as well.

So, when you’re looking for epoxy resin, make sure it’s safe and free from such contaminants. On top of that, look for an epoxy that does produce harmful fumes or volatile organic compounds.

One of my favourite brands and I find the safest so far is ArtResin. It is Non-toxic when used as directed. Artresin has No VOCs. No BPA. No fumes. Non-flammable and is Certified food safe.

Are All Epoxy Resins Toxic?

Chemical composition determines if any epoxy product is toxic or not. This is because epoxies contain different compounds that bond and harden on curing. Fortunately, some products contain natural ingredients, while others have harmful chemicals.

Non-toxic epoxies have safe compounds like BPF (Bisphenol F) and BPA (Bisphenol A). Researchers are still studying the long-term health impacts of these compounds. However, up to date, BPA is deemed safe for consumption.

On the contrary, toxic resins contain harmful ingredients such as VOCs. Unlike BPA, these compounds are harmful and can cause long-term health concerns.

Unfortunately, different manufacturers make their products differently. On top of that, most companies don’t include the ingredients used in their resins.

This makes it hard to determine if their products contain harmful substances or not. In short, unless you determine the composition of a certain epoxy, it’s hard to know if it’s toxic or non-toxic.

When Is Epoxy Resin Toxic?

This special type of resin exists in 3 forms; uncured, cured, and dust. To determine if the resin is toxic or not, you need to understand these stages.

The cured state is the final stage where it has completely hardened. Hence the material is said to be not toxic anymore. That’s why you’ll see with epoxy resin, people are crafting tumblers as a hobby or profession. So, you can safely touch it and even put items on it.

However, that’s not the case with its dust and uncured/ liquid state though!

Epoxies come with 2 separate components: resin and hardener. You must mix these components to experience their adhesion properties. However, mixing them triggers an exothermic reaction and produces harmful vapors.

Inhaling or breathing these vapors can cause respiratory problems. So, you need to wear a breathing mask when working with epoxy.

Moreover, you’ll experience immediate symptoms if liquid epoxy contacts your hands or skin.

This is because it reacts with your skin, causing skin rashes and irritation.

Always Wear A Respirator

What Is Required to Work With Toxic Epoxy Resin?

To protect yourself from epoxy, there are some safety measures you need to observe. This will enable you to complete your project smoothly and healthily. Here are safety precautions you need to adhere to;

1. Use PPE (Personal Protection Equipment)

Before you start working, wear proper protective gear. This includes pants and a long-sleeved shirt to cover your entire skin. Moreover, you’ll need nitrile gloves, a respirator/ breathing mask, and safety goggles.

2. Increase Ventilation

Another need to do is to ensure you’re working in a well-ventilated space. This protects you from inhaling the fumes produced after mixing resin and hardeners. To increase ventilation, keep any windows, doors, and hatchways open. You can also add some fans in the room to increase air movement.

3. Observe Personal Hygiene

After finishing your epoxy project, the best most effective way to remove it is

Recipe For Getting Resin Off Of Your Hands And Skin:

  • Pour about 1 tbsp. baking soda right into your hand.
  • Don’t add any water!
  • Pour about 1 tbsp. of dish soap onto the baking soda.
  • Scrub your hands together over a sink.
  • Rinse your hands. Repeat if necessary.

Also, avoid rubbing your hands or eating any food with hands that contain resin residues.


On curing, the resin is usually considered safe, both for pets and children. However, it’s always good to take the necessary safety precautions while working with it.

Remember, uncured epoxy can cause health problems like allergies and irritation. Apart from that, it’s a wonderful product for creating beautiful art and crafts.
