Is tung oil food safe?

Though pure tung oil is food-safe, most oils sold as tung oil include only a small amount of tung oil, and the remainder comes from boiling linseed oil, metallic driers, and solvents. Consider it food safe if it can dry completely for at least 30 days. 

Pure Tung oil is generally safe to eat once it cures. It’s a standard oil used on cutting boards, butcher blocks, hardwood counters, and wooden toys, among other things. However, some Tung oil brands include chemical additives that you should avoid. To be safe, give it up to 30 days to heal.

What type of oil is tung oil

Tung oil is a natural drying oil derived from the tung-tree nut that leaves a translucent, moist gloss on fine wood furnishings. It enriches the color of your wood while also providing exceptional protection and being environmentally friendly. Tung oil is known as a natural oil that has been used in woodworking for hundreds of years and is still one of the most popular finishes due to the various benefits it provides. 

Tung oil is one of the most well-known oil treatments for wood furniture. It’s a natural, eco-friendly wood finishing product derived from the crushed seeds of the tung tree. It’s different from other finishing oils in that it’s an excellent protective finish that shields your woodwork from the elements. It’s ideal for protecting bare and unpainted wood from staining and marking over time.


Tung Oil is an excellent choice for kitchen worktops, cooking equipment, children’s furniture, toys, and even outside wood-like decking.

Is it safe to ingest            

Tung oil comes from the poisonous seeds of the tung oil tree. Tung oil can induce severe gastrointestinal problems, such as stomach pain, diarrhea, and vomiting when consumed or cooked with it. People who become ill after swallowing tung oil require medical attention to relieve gastrointestinal symptoms and restore fluid and electrolyte balance.

What are the toxins in tung oil?

Aldehydes and hydrocarbons originate during tung and linseed oils (curing). During oxidation, peroxides, alcohols, ketones, and acids may also offgas. The majority of people, as well as healthy people, are unaffected by these substances. Aldehydes, in particular, can be toxic or induce symptoms in individuals who are already vulnerable. And this might be dangerous if you’re chemically sensitive or have a damaged immune system. It does, without a doubt, cause you to experience symptoms.

Is it safe for pregnant women?

Even though tung oil is non-toxic and food-safe, it’s usually advisable not to varnish wood while pregnant, just in case. During pregnancy, chemical solvent exposure may increase your chances of having a baby with congenital disabilities. 

According to one study, women who were often exposed to solvents when repairing cars, painting, or stripping furniture had a slightly greater risk of having a kid with gastroschisis. If you’re pregnant, the easiest and safest choice is to have someone else handle the varnishing or postpone it until after your kid is born.

Lead dust or fumes can cause brain damage and other health problems, particularly in children and pregnant women. Controlling lead or additional hazardous substance exposure necessitates using protective equipment such as a properly fitted respirator and effective containment and cleanup.

Is Formby’s tung oil food safe

Formby’s tung oil is not food safe because it is not 100 percent pure tung oil. It’s best to avoid food-related projects and utensils. Formby’s Tung Oil Finish is a varnish impregnated with Tung Oil rather than a refined oil finish. It’s a mixture of tung oil and other refined penetrating oils that looks like a wiping varnish with a smidgeon of oil and many thinners.

You apply it with a rag and buff it into the wood, repeating the process three times to get a nice close-to-the-wood finish with a good shine. Between coats, let it dry overnight or for at least 12 hours. And this means that the drying time, as well as the time between coats, is significantly reduced.

Is tung oil safe for cutting boards?

Because pure tung oil is entirely natural and food-safe, you can use it to finish a cutting board (or any other food-related project). Apart from being food-safe, tung oil has several other advantages, including being very simple to apply, safeguarding the wood from scratches, and waterproofing the wood. 

Nuts are the source to obtain tung oil. It’s known for its water resistance, but it often necessitates multiple coats. It leaves a natural finish on the wood that darkens it while highlighting the grain. It is safe to eat once it has adequately cured.

When buying tung oil on your cutting board, the most important thing to remember is to make sure it’s pure. Unfortunately, most tung oil-labeled goods on the market contain only trace amounts of pure tung oil, with additives making up the rest of the product. As you might expect, such items are far from natural or food-safe and are not ideal for use as a cutting board.

To verify that the tung oil you buy is pure, buy it from a reputable company and check the package to see whether it says it’s 100% hygienic and food-safe. Avoid using anything that doesn’t say it’s pure or food-safe on your cutting board.
