Some artists love creating handmade items like cutting boards and eating utensils using epoxy resin, while others are interested in making beautiful food trays with epoxy, but they are concerned about the safety of using this material for food-related items. So, is epoxy food safe?” The answer is yes, but it depends on different types of epoxies. In this article, we'll help you learn how to choose food-safe epoxy resin, share key safety guidelines for working with it, and suggest some great options for food-safe epoxy resin products. Let's get crafting safely and confidently!
According to the food conformity requirements of the Food and Drug Administration (FDA), "Epoxy Food Safe" means that when fully cured and used as directed, epoxy is inert and will not leach any chemicals or release any taste or smell into food that it comes into contact with. Epoxy food safety also guarantees that people’s health is not endangered when food is exposed to epoxy. Moreover, it also indicates that this type of material releases no or very few free components into the food.
However, while a substance may be labeled as food-safe, it doesn't automatically mean it's suitable for all food-related purposes. While it's okay for the epoxy to come into contact with food and be touched before eating, it's not recommended for use as a food storage container or plate.
*Note: It's important to note that when we mention epoxy being safe for handling food and consumption, we are talking about cured epoxy specifically. Before curing, liquid epoxy resin is toxic and should never be used with food or drinks. So, always make sure to handle epoxy safely and appropriately for your food-related needs.
If you are figuring out “is epoxy resin food safe?”, here you are! We've got you covered with 4 simple ways to check for yourself!
Check The Product Label And Documentation
To determine epoxy resin safety, inspect the label for hazard symbols like flame icons or skull and crossbones, which indicate potential risks. Or you should consider precautionary statements such as "do not ingest" are also red flags that the resin may not be food safe.
Additionally, we have to always prioritize safety and double-check information about food safety grade and toxicity. Here are some tips you should keep in mind when buying epoxy products to ensure they are safe for food:
Label on products that states “FDA compliant”: Being "FDA compliant" ensures that a product has met the health and safety standards established by the United States Food and Drug Administration. With "FDA-compliant epoxy resin," following the instructions on the label and allowing it to fully cure guarantees that it is safe for direct contact with food.
Low or no levels of BPA on the ingredient list of epoxy: BPA, short for Bisphenol A, is a chemical compound utilized in producing sturdy epoxy resins and polycarbonate plastics that have direct contact with food. Although certain research suggests potential health risks associated with BPA, the FDA in the United Statesmaintains that BPA will be safe at very low levels.
Material Safety Data Sheet (MSDS)
This sheet provides valuable information about the chemical properties and classifications of the resin components, giving you insight into whether it is safe for food contact. Additionally, the MSDS includes important details about personal protective measures that should be taken to ensure your safety when working with the resin.
Contact The Manufacturer
Reaching out to the manufacturer directly is also the best way if you are unsure whether your epoxy resin is food-safe. They will be able to provide you with accurate information regarding the safety of their product for food contact. It's always better to be safe than sorry when it comes to using materials around food.
Certifications And Standards
There are certifications and standards you can look for to ensure whether your epoxy resin is safe for food contact. Here are some of the most reputable food safety certifications for epoxy resin according to different countries:
By checking for these certifications, you can have peace of mind knowing that your epoxy resin is safe for food-related uses.
Independent Laboratory Testing
One reliable way to ensure that your epoxy resin is safe for food contact is through independent laboratory testing. This involves thorough migration and leaching tests conducted by a reputable third-party lab.
For example, if you send resin samples to reputable laboratories such as Foodtest Laboratories Ltd, which provides ISO 17025-certified testing services, and then receive the results of these tests showing that the epoxy resin meets government food safety regulations, it will give you peace of mind when using it for food-related applications.
Safety Rules for Food Safe with Epoxy Resin
Safety first! Here's everything you need to know about using epoxy resin in your kitchen to keep your food safe and your art projects stunning.
Following instructions and the suggested ratio: This ensures that the epoxy cures properly and is safe for food contact.
Avoid excessive heat: It is vital to refrain from heating cured epoxy resin beyond 165°F, as excessive heat can release harmful chemicals from the resin.
Microwave caution: Don’t place the epoxy resin project into a microwave because microwaves can cause the resin to melt and potentially release toxic fumes.
Full curing required: Don’t use epoxy resin if it is not fully cured because if we use resin uncured, it contains a lot of harmful chemicals such as bisphenol A (BPA) and epichlorohydrin. These chemicals can potentially leach into food and be ingested, posing health risks to consumers.
Alcohol interaction: Not allowing epoxy resin coating to come into contact with alcohol because alcohol can break down the chemical bonds in the resin, causing it to weaken, crack, or even peel off over time. As a result, it potentially leeches harmful substances into food.
Safety Data Sheet (SDS) inspection: Refer to the safety data sheet provided by the epoxy resin manufacturer to understand the potentially hazardous compounds that could be present in the resin.
Factors Affecting Food Safe Epoxy
As we mentioned above, epoxy food is safe when the product is used as directed and fully cured. So, how long does resin take to cure? Our article has analyzed the average curing times for popular resins to help you do your resin projects properly. Besides, let's take a closer look at other factors that can influence the safety of food-grade epoxy in food:
Colorants: If you use a non-toxic and non-flammable epoxy resin, be careful when adding colorants as some may affect its safety. For a safe option, try ResinTint liquid colorants. They are non-toxic, mineral oil-based, solvent-free, and made to work perfectly with epoxy resin.
Coating: There are some popular options for a clear finish coating for your food-related project without using epoxy resin. For example, Shellac is a great choice for a food-safe finish that's water-resistant. You could also try polyurethane, which is durable and commonly used by woodworkers. For tumblers, consider using CrystaLac, a water-based polyurethane that's gaining popularity as a safe alternative to epoxy resin. Woodworkers can also opt for spar urethane for their projects.
Incorrect mixing ratio: Incorrect mixing ratios of epoxy can lead to incomplete curing, resulting in a sticky or soft finish that can contaminate food.
Insufficient mixing: This can result in patches of the surface not being properly sealed, allowing for potential contamination of the food.
Temperature of the food: Extreme temperatures can cause the epoxy to warp, crack, or degrade, which may not only compromise food safety but also the structural integrity of the surface. So, avoid placing food or liquids above 165°F on the epoxy resin surface.
Acidity or alkalinity of the food: Epoxy coatings are generally resistant to a wide range of pH levels, but extreme acidity or alkalinity can potentially deteriorate the epoxy over time, compromising its food-safe properties.
Concentration of the alcohol: Higher concentrations of alcohol may speed up the curing process, while lower concentrations may slow it down. This can impact the final strength and durability of the epoxy once it has hardened.
Pigment types and load levels: Certain pigments such as Titanium Dioxide, Copper phthalocyanine, and Chromium Oxide Green may contain harmful chemicals that could leach into food if the epoxy is used in food contact surfaces. Various pigments are safe for food when used with epoxy, including titanium white pigment, pearl powders,...
Exposure of the hardener to carbon dioxide: If the hardener is exposed to excessive amounts of carbon dioxide, it may not cure properly or may develop bubbles and imperfections in the final finish. This could compromise the food safety of the epoxy by creating uneven or unstable surfaces that could harbor bacteria or contaminants.
