Is Epoxy Resin Safe For Food Contact?
Whether a resin project can come into direct contact with food or not depends on the chemical composition of the products used to make it.
There are many different epoxy resin brands on the market, but not all of them are non-toxic and food safe. In fact, many formulas require warning labels to alert consumers that the product is poisonous, carcinogenic or hazardous to the environment. To ensure that the epoxy resin you’re using is food safe, look for a resin that has been evaluated by an independent lab and whose test results comply with worldwide food safe regulations.
Note : The EU, Australia, Canada, Great Britain and the USA have their own governing bodies that outline food safe regulations. You can check for compliance with food safe standards on the epoxy resin manufacturers’ websites.
Use a food safe epoxy resin to safely prepare or serve food on the following surfaces:
Charcuterie boards
Serving trays
Fruit bowls
Epoxy resin tables
Drink ware, like mugs and tumblers
Countertops
Coasters
Candy dishes
Plates or tableware
Please note that a resin is only considered safe for food contact once it has fully cured. Keep food or beverages well away from resin and hardener in its pre-cured, liquid form. Epoxy resin is not edible or potable in either liquid or cured form.
What Exactly Does "Food Safe Epoxy" Mean?
A “food safe epoxy resin” means that when the product is used as directed and fully cured, it is inert and will not leach any chemicals into food that comes into contact with it.
Epoxy resin is a material created from the chemical reaction between resin and hardener. Some epoxy resin formulas contain solvents and diluents to stretch the materials - these non-reactive fillers can leach out of the product and pose serious health risks if breathed in or ingested.
Ensure that the epoxy resin you’re using is a food grade epoxy by consulting the manufacturer’s safety certifications on their website, the Safety Data Sheet, and by accurately following the recommended mixing instructions.
Some of the most established food safety certifications for epoxy resin are:
US: FDA 21 CFR 175.300 Resinous and Polymeric Coatings
EU: Food Contact Plastics Regulations EU 10/2011
GB: GB 4806.7-2016 National Standards For Food Safety
AUS: AS 2070-1999 Plastic Materials For Food Contact Use
CA: Canada Consumer Product Safety Act SOR 2018/83
FDA Compliant Epoxy Resin
What does “FDA compliant epoxy” mean in the first place?
“FDA compliant” means that the product has been evaluated and found to meet the health and safety standards set out by the United States Food and Drug Administration. FDA-compliant epoxy resin” means that, if prepared according to the label instructions and allowed to fully cure, the product is safe for direct contact with food. In other words, FDA compliant epoxy resin has been found not to leach harmful components into food that it has been in contact with.
ArtResin® Epoxy Resin is one of the few epoxy resins to have been tested for leaching in 13 different food safety tests and passed each one. ArtResin not only gives your creations a beautiful, shiny finish, but it is 100% food safe once cured.

Are Epoxy Resin Colorants Food Safe?
Even if your epoxy resin is non-toxic and non-flammable, adding certain resin dye or colorants can compromise the product’s safety designation. For example, alcohol ink is a flammable solvent and once it has been added to an epoxy resin creation, the resin is no longer considered non-toxic. Alcohol ink can be used in resin to create stunning pieces of petri art. Just remember not to use alcohol ink for crafting resin pieces intended for food.
For those looking for a safe colorant to add to your epoxy resin work, take a look at ResinTint liquid colorants. They are non-toxic, mineral oil-based, contain no solvents, and were designed specifically to work with epoxy resin.
💡Tip: If you’re not sure that the colorant you’re using is non-toxic, simply add an extra layer of clear, non-tinted, food-safe ArtResin® as a final topcoat on your epoxy creations to ensure it is safe for use in direct contact with food.
What Is BPA?
BPA stands for Bisphenol A; a chemical compound used to manufacture clear and durable epoxy resins and other polycarbonate plastics that come in direct contact with food products. Some studies have shown that BPA might be connected to specific health problems, however, the United States Food and Drug Administration (FDA) has declared that BPA is safe at very low levels.
How To Protect Yourself Against BPA In Epoxy Resin?
Should BPA worry you? For peace of mind and to reduce exposure to BPA while crafting resin artwork, your best line of defense is to choose a BPA-free epoxy resin, like ArtResin®!
How is ArtResin A BPA-Free Epoxy Resin?
ArtResin is BPA-free, non-toxic and does not release harmful chemicals. Here are the facts:
BPA is one of the precursors to epoxy, but it is fully reacted during Artresin’s manufacturing process, leaving behind only trace amounts. These trace amounts are so low that ArtResin epoxy resin is certified as BPA-free.
ArtResin is a complete system, meaning that Parts A and B of the ArtResin formula - the resin and the hardener - fully react when combined, leaving nothing behind that can become airborne. There is no chance of exposure to even those miniscule amounts of BPA. It also means there are no volatile organic compounds (VOCs) or other harmful solvents released into the air.
-
Once cured, ArtResin is compliant with
FDA CFR 175.300
and “may be safely used as the food-contact surface of articles intended for use in holding food” and “intended for repeat food-contact use”.
ArtResin® has undergone numerous in-depth safety evaluations and environmental tests to ensure that it is safe to use. Learn more about them in the video below.

How Do I Know If My Epoxy Resin Is Food Safe?
Check on your resin’s label for hazardous symbols, precautionary statements and for information about food safety grade and toxicity. For more detailed information, consult the Safety Data Sheet (SDS) on the manufacturer’s website. There you’ll be able to see the chemical properties and classifications of the resin components as well as personal protective measures to ensure your safety. If you still have concerns and questions, contact the manufacturer through their customer hotline or their website contact form.

ArtResin® Epoxy Resin is safe to use because it contains no solvents, no BPA and does not release toxic substances like VOCs that can put your health at risk. Be aware, however, that not all epoxy resin brands are non-toxic: many are considered hazardous materials and should not be used without following safety precautions. If in doubt, look for the safety standard “ Conforms to ASTM D-4236” and “ Safe For Use At Home” on the label, like you'll find on ArtResin's label.
To protect your health, make sure you follow these best practices:
- Wear disposable, nitrile gloves while in contact with epoxy resin
- Choose long-sleeved clothing.
- Work in a well-ventilated space.
- Avoid eating or drinking while crafting with epoxy resin.
- When sanding cured epoxy resin, wear a safety mask to avoid inhaling sanding dust.
Clean up spills and drips on work surfaces immediately.
Do not use alcohol, acetone, vinegar or other solvents to wipe epoxy resin from your skin. Instead, use an exfoliant cleanser.
Remove all traces of epoxy resin with alcohol before washing tools in hot soapy water.
Do not pour liquid epoxy resin or hardener down the drain.
- Do not use non-food safe epoxy resin to craft surfaces and objects that come in direct contact with food.
- Check the epoxy resin manufacturer’s safety data sheet to get informed about potential hazardous compounds that may be present in the resin and hardener you use.
Treat Skin Irritation Promptly
When working with resin, always wear disposable nitrile gloves to minimize skin exposure and possible irritation. If you experience a reaction such as skin irritation or swelling after working with epoxy resin, discontinue use and seek prompt medical advice.
Approximately 2% of users will experience an allergy to the basic components of epoxy resin. Skin reactions may present as itching, irritation redness, swelling or blisters and typically subside once exposure is discontinued. Allergic reactions are unpredictable, however: you may experience a reaction right away or an allergy could develop over time with repeated exposure. An allergic reaction to epoxy resin is not specific to a certain brand - if you experience an allergic reaction one epoxy resin, you will react to them all and the advice would be to discontinue use indefinitely.
ArtResin's Non-Toxic and Food Safe Status Can Change With The Addition Of Foreign Products
ArtResin is non-toxic on its own but be aware that adding products that contain toxins and solvents will alter its safety status. For example, adding alcohol ink to resin creates a cool, colorful effect, but alcohol is a solvent which means the final product can no longer be classified as non-toxic.
Similarly, ArtResin is non-flammable in its liquid form when used as directed, and we recommend using an Artist’s Torch to pop bubbles. Running a flame quickly and systematically over the entire resin surface will eliminate any trapped bubbles and not cause a flammability risk. However, if flammable products, like alcohol ink, have been added to the mixture, it will compromise the non-flammability of liquid ArtResin.
For this reason, we have developed ResinTint , our non-toxic, non-flammable premium colorant for ArtResin. If you're looking for a colorant for your ArtResin and want to preserve the non-toxic, non-flammable nature of the formula, then ResinTint is the perfect option!

Is Epoxy Food Safe?
By Roderick Kabel
We are asked the question more than once a week and there seems to be quite a bit of confusion out on the internet. In this article we will help to clarify a few things around this topic - even though we are not chemists or experts – a few guidelines to follow will help us all out.
We understand people’s worries about food contact with epoxy and their need to know for practical purposes. When considering our market, deep pour and table top epoxy, epoxy contact with food is a normal, everyday occurrence. The bottom line here is this; epoxy is two liquid components that are each made from chemicals; and then mixed together to create a completely new solid substance which is absent most of the initial liquid formula compounds - after a full cure. Though, the takeaway word here is “chemicals.”
Here is an excerpt taken from Wikipedia: “Epoxy is either any of the basic components or the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group.[1] Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups.
Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing.”
Would anyone knowingly ingest any of these chemicals in liquid or cured form either directly or indirectly? No, they wouldn’t.
But that’s not the question, is it? The question when asked, is communicated as food touching a cured and hardened epoxy surface, right? However there are too many variables and for-instances where any food could come in contact with hard cured epoxy.
For instance, would you eat scrambled eggs off an epoxy surface? Yuk. How about making a peanut butter and jelly sandwich where the bread touches the epoxy? Maybe. Would you cut raw meat on epoxy? Nope!
What’s more frightening is the other form of this question. “Is epoxy ‘Food Grade’?” And herein lays the real problem. These two seemingly innocent food and epoxy questions are frequently interchanged and they are two very different things. Just ask the FDA.
Keep in mind “Food Grade” epoxy is formulated as such that its raw material chemical make-up is not harmful as well as the cured epoxy not being harmful. Furthermore, manufacturers must go through expensive and extensive testing with the FDA to be certified as a “Food Grade” epoxy.
The FDA’s Title 21, Volume 3 report shows that food safe epoxy does indeed exist. Even though epoxy is generally not connected with a specific setting in the kitchen, several brands claim their epoxy is formulated with FDA approved raw materials. This means that certain epoxies are safe for both direct and indirect contact with food, as regulated by the FDA. These epoxies "comply" with CFR 175.300 and are ideal for bonding and sealing food contact equipment, utensils and appliances.
Nevertheless, the problem here is a distortion of information, kind of like the telephone game we all played in grade school where the message told, got all jumbled by the time it reached the last person.
All over the World Wide Web and from peer to peer, epoxy newbies, experts and even manufacturers are blurring the lines. Newbies always ask if epoxy is Food Safe; experts say yes, because they tend to rely on their epoxy brand’s “food safe” literature. Then, there are the epoxy manufacturers whom have created a loop hole by leaning on and referencing the FDA and their Code of Federal Regulations Title 21.
https://www.accessdata.fda.gov/
So what’s the answer? The simple answer here is, yes, epoxy is generally safe around food because it is an inert plastic when properly mixed and cured. However that’s not necessarily a reassuring answer because again, the answer depends completely on what the epoxy will be used in, or on a finished project surface, and how will any said foods actually come in contact with the epoxy.
The prospects for using epoxy for contact with food, has increased immensely. Many individuals are using epoxy for table tops, bar tops, counters, cutting boards, charcuterie, serving trays, drink tumblers, and many others.
Our view is this: WiseBond® Epoxies are 100% solids and VOC-Free. Once epoxy is mixed properly according to the instructions and fully cured for 30 days, it is an inert plastic. It is not antimicrobial. Epoxy is not safe to ingest (liquid or cured). Do not cut on or prepare raw food on epoxy surfaces.
SAFETY: Products "WiseBond® Deep Pour 2” Epoxy: Part A and B, and WiseBond® Bar & Table Top Epoxy: Part A and B", are resinous polymeric coatings. These resinous polymeric coatings have been tested by an independent Testing, Inspection and Certification laboratory for conformity to Food and Drug Administration (FDA) standards as required by USFDA 21 CFR 175.300 Condition E from Table 2. Tested epoxy passed the CFR extraction testing under the conditions of use that were requested. The products were found to be in compliance with the US Food and Drug Administration regulation, 21 CFR 175.300, Condition E, for surfaces in contact with food at room temperature. Other conditions of use or variations in application of the resin for the specific application would potentially require follow up testing.
NOTE: The above statement refers to “clear” epoxy only. Adding any type of colorant to either epoxy, alters the epoxy formula and it will no longer conform to the USFDA 21 CFR 175.300 tested results.

Okay, you say… that’s all fine and dandy but you still want to put food on your epoxy countertop. Well, let’s look a little deeper into the make-up of epoxy.
A key compound of epoxy is the ingredient Bisphenol A (BPA) or Bisphenol F (BPF). Over 60 percent of all epoxies contain or have large amounts of Bisphenol A. Bisphenol A is an industrial chemical and has been around since the 1960’s to create polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles and beverage can linings.
In 1997, adverse effects of low-dose BPA exposure in laboratory animals were first discovered. Studies began finding possible connections to health issues caused by exposure to BPA during reproduction, pregnancy and during embryo development.
In 2003, U.S. consumption of BPA was 856,000 tons, 72% of which used to make polycarbonate plastic and 21% going into epoxy resins. In the U.S., less than 5% of the BPA produced is used in food contact applications, but remains in the canned food industry and printing applications such as sales receipts.
As of 2014, research and debates are ongoing as to whether BPA should be banned or not. The CDC reported that BPA detectable levels were found in 93% of 2517 urine samples from people six years and older.
In 2015, OEHHA (California Office of Environmental Health Hazard Assessment) listed Bisphenol A as a carcinogen to their Proposition 65 list because it can harm the female reproductive system, including effects on ovaries and eggs.
On April 1, 2016, the California Code of Regulations, operated by the OEHHA, filed an Emergency Action to amend section 25603.3 Title 27 warnings for exposures to Bisphenol A from canned and bottled foods and beverages.
https://oehha.ca.gov/proposition-65/
OEHHA determined that it could not develop a safe harbor level for oral exposures to BPA and realized that businesses would take inconsistent approaches to compliance. Inconsistent warnings in general, would confuse citizens on a topic of vital importance to them — food safety. Consumers needed to have clear choices between food and beverage products in BPA-containing and BPA-free packaging.
There was evidence that between 66% and 90% of canned foods contain varying levels of BPA. Given the long shelf life of these types of products, some of them were likely manufactured prior to the listing of BPA in 2015. The only viable way to provide warnings for these products, absent the emergency regulation, is with shelf signs and point-of-purchase signs. Once these older products are no longer in the stream of commerce, OEHHA expects many newer products requiring warnings will have them on the product label as required by the FDA. The effects of BPA are still under review by the FDA however.
On the other hand, these specific levels of BPA are extremely low when used in canned beverages and bottled foods in comparison to the large volumes of epoxy used for art crafts and epoxy table making.
Studies on BPA have found it to be harmful to health, but there is no way to get around the fact that many epoxies on the market are formulated from it. Until a viable new solution is developed and marketed, we all need to be as informed as possible.
The difference between epoxy brands lies primarily in what the epoxy is intended for. Some individuals use epoxy for coating oil paintings, aircraft adhesives, or to coat the inside of one’s boat. Therefore, the epoxy used in these situations does not have to be food safe/grade. Conversely, individuals using epoxy in applications where food can be, and will be in contact with epoxy must understand the risks of not using an FDA certified food safe or food grade epoxy.
Carefully following instructions during the curing process dramatically decreases the adverse effects of incorrect proportioning and will ensure that the epoxy used is at its highest quality.
Epoxy, when cured, is generally “food safe” for incidental, short-term contact with food, and epoxy is also not always “food grade.” Two very different distinctions. It is solely up to you, the epoxy user, to evaluate the practicality of your epoxy usage and application when in contact with food.
