Super glue is an increasingly popular glue in woodworking and is used to bond different materials together. But before you get started with this powerful glue, it’s good to think about the question, is super glue food safe?
You may want to make cutting boards or another kitchen item that will come into contact with food, so you want to be sure you use a non toxic glue.
Super glue is not food safe due to the toxicity of cyanoacrylate, the chemical term for super glue. It can’t be used on cutting boards or other wooden items that come into contact with food, either directly or indirectly. Continue reading to learn why and to explore some simple alternatives.
This blog post discusses the food safety of superglue and how it is determined. That is why you will receive a more detailed answer to the question, “is super glue food safe?” and also what alternatives there are.
What is super glue?
Super glue (also known as cyanoacrylate adhesive in the industry) is a form of fast-bonding, high-strength, and immediate adhesive that can bond practically any material.
Harry Coover Jr. discovered this kind of adhesive in 1942. It was first commercially produced by Loctite in 1958. It soon gained popularity, and other well-known brands such as Starbond, Gorilla, Elmer’s, Infinity Bond, and many others now produce it.
what is super glue used for in woodworking?
Super glue is a powerful, quick-bonding adhesive that can stick to nearly any surface or substance. They’re frequently used to make rapid repairs around the house, including repairing cracks and replacing damaged things.
In woodworking workshops, super glues are often used to glue wood, metal, plastic, paper, or stone together because of their temperature and moisture resilience.
It takes only a few seconds to set and only a few drops to form an incredibly solid connection.
After applying super glue, and when the glue comes into contact with hydroxyl ions in moisture, the acrylic monomer cyanoacrylate cures to a plastic state. When fully dried, super glue makes a very strong, long-lasting connection.
As a result, super glue only needs water molecules to bond. As long as moisture is present, it can stick to almost any surface. Super glue can be used on almost any surface as there is always moisture in the air.
The main characteristic of superglue materials is their fast bonding time.
The bonding process is generally faster in situations with higher humidity, because super glue bonds with moisture. Because it is a one-component glue, you can use super glue right away, without having to mix it with another component.

In this article, you will also get informed on how to use it, what the accelerator does, and how to securely store and extend the shelf life of superglue.
is super glue food safe?
The major component in super glues, cyanoacrylate, is a chemical and dangerous substance that should not come in contact with products that will be consumed. As a result, super glue products are not recognized by the FDA for direct or indirect food contact and are not considered food safe.
So, in short, the answer to the question “is super glue food safe?” is NO!
So, if you wish to build wooden items for your kitchen like cutting boards or anything else that comes into direct or indirect touch with food, you should never use super glue. Even if you have little objects to fix that come into touch with food, you should never use super glue, no matter how minor the repair.
For this, you’ll need a non toxic glue that doesn’t include cyanoacrylate to keep yourself and others safe. There are a variety of non toxic glue options available that may be used in place of super glue.
Is super glue food safe after it dries?
The answer to the question “is super glue food safe after it has dried?” is the same as the question “is super glue food safe?”.
The toxicity of superglue does not vary, even after it has been cured. So, dried super glue is not food safe.
When this dried glue comes into touch with food, the moisture in the food releases the poisonous components, allowing them to enter the food.
What you also need to know is that super glue can cause skin irritation. On contact with the skin, cyanoacrylates have been observed to trigger an allergic response in some situations.
However, this is unusual and occurs more commonly when using superglue to make glue ups while it is still in liquid form. So if you’ll ever use super glue, you better protect yourself.
What criteria does the FDA use to determine which adhesives are food safe?
The usage of adhesives is regulated differently in various countries and by different legislative agencies. The Food and Drug Administration (FDA) is the most significant of them. In general, adhesive manufacturers must adhere to the formulation guidelines established by FDA regulations.
The most significant rule is that FDA-compliant adhesives must be made from raw ingredients that have been pre-approved. This implies the FDA has a long list of basic elements that have been shown to form non-toxic bonds.
When it comes to plastics or chemicals that come into touch with food or the food processing process, all materials must comply with stringent food safety regulations. Safety tests must be passed regardless of whether the materials are utilized in packaging or in an industrial setting.
Which adhesives are considered food safe ??
Animal components, such as bones and skins, are used to make some types of wood glues. Animal hide glues are what they’re called. Because the glues contain animal-derived components, they can form a non-toxic bond and are thus food-safe.
Aside from animal hide glue, two-component epoxy glue is another form of glue that is certified food safe. This sort of glue provides the best results for its consumers by forming high-strength bindings.
The two-component epoxy adhesive also has a quick adhesive cure rate, which can be as little as a few minutes in some cases. The fact that two-part epoxy glue is made using components that are certified food safe by the FDA is its most notable feature.
Epoxy and resorcinol, a crystalline phenol that may be manufactured or generated from organic components, are used to make two-component adhesives. The glue is one element of these sorts of adhesive products, and the catalyst is the other.
What non toxic glue can be used? Super glue alternatives.
It would be weird to give you a negative answer to the question, “is super glue food safe?” and close this article.
That is why I have provided two alternatives for gluing objects that come into touch with food that you may use without guilt.
So, whether you need to repair a cracked coffee cup or want to construct a cutting board out of scrap wood, these two types of non toxic glue are a good choice.
Titebond III Ultimate wood glue
The first non toxic glue is the Titebond III wood glue, and so far, the only wood glue I know of that is made according to the formulation guidelines set by FDA regulations.
That is why this powerful wood glue is the perfect glue for cutting boards.
Moreover, you should not be afraid that the glue would come loose due to contact with water, because this wood glue is suitable for outdoor use.
This wood glue binds within 30 minutes and is fully cured in 24 hours.

Elmer’s China and Glass Cement
A second non toxic glue that is food safe is the Elmer’s China and Glass Cement
This adhesive may be used on everything that comes into touch with food, including glass, ceramics, and pottery.
This self-adhesive solution is meant to be applied quickly and simply to any surface. The items may be cleaned in the dishwasher after using this adhesive because the glue is dishwasher safe.
This glue starts working in less than a minute and takes two or three days to attain maximum strength.
Elmer’s E1012 glue is created from components that are entirely FDA-approved. This implies the glue is safe to eat and can form non-toxic connections with other materials.
