Is Le Creuset nail polish toxic or safe in 2023? (2023)

Many seasoned and experienced chefs rightly say: cooking is a science! With any kind of science, you should be aware of the possibility of toxins. This is especially true of the utensils you use to prepare your food, hence the question: is Le Creuset enamel toxic?

Although some used cookware materials can introduce small amounts of toxins into your diet over time, Le Creuset enamel actually acts as a barrier. Enamel withstands high cooking temperatures, protects your food from toxic spills, and protects your cast iron cookware from rusting.

In this article, we'll go over whether or not Le Creuset enamel is toxic, what makes it safe to cook with, and how it's unique among other coating options. Finally, we'll go through some frequently asked questions on the subject to help home cooks understand everything they need to know about Le Creuset enamel toxicity.

Is Le Creuset Enamel Toxic?

While Le Creuset enamel, used as the enamel coating on many non-stick pans, is an incredibly popular product, the question remains: is it safe? No wonder this question has been raised in the media about chemical leaching into our food.

Some pans, like those made from carbon steel, are considered safe because they are uncoated and made from only non-toxic materials. But does that mean that we have to completely do without non-stick coatings such as enamel?

The truth is that Le Creuset enamel does not pose a major toxicity hazard to humans. To be really sure about this, it's important to understand toxicity in relation to the cookware we use, as well as what Le Creuset enamel really is. We'll take a closer look at these topics below!

What is Le Creuset?

If we want to be absolutely sure that products containing Le Creuset enamel are not harmful to us, it can help to know what Le Creuset really is and what it is made of.

Le Creuset is a France-based company that has been in business since 1925. A hardware store owner named Armand Desaegher and his friend Octave Aubecq founded the brand. They still work out of the foundryMelville, France.

Le Creuset offers non-stick metal bakeware, signature cookware in stainless steel, stoneware and yes, enameled cast iron! Not only are these popular for their non-stick coating, but for their gorgeous design with over 20 vibrant colors to choose from.

Not only are they high quality when it comes to non-stick cookware and bakeware, but they can be placed on any counter and actually add to the overall decor of most kitchens.

What are Le Creuset products made of?

One of their celebrity claims is that their products are made from natural materials extracted from the earth and are largely free of toxins (although it is normal to discover very small elements of toxins in any product made from metal, such as e.g. iron ). .)

The enamel itself is actually a layer of powder that has been fused onto the metal of the cookware, which adheres to the actual pan in a seamless layer. Three coats of enamel are applied to the regular cast iron core, meaning all of the metal oxide particles that make up the pot or pan are encased in a glass matrix.

Not even acidic foods can penetrate this coating! This makes this enameled cast iron cookware one of the safest ways to cook.

During this entire process, no chemicals are used in the manufacture of the product. This essentially means that heating the pot or pan in an oven or on a stovetop will not release any toxic chemicals or noxious fumes during your cooking adventures.

Le Creuset enamels its cast-iron frying pans because this makes them durable, even after long periods of use. In addition, the thin glass layer of Le Creuset enamel can also prevent small amounts of iron from getting into the food prepared with the cookware!

Finally, one of the best things about Le Creuset enamel is that it protects your cast iron cookware from rust damage. This thick coating has three layers of protection between the metal and the remaining water molecules.

Taken together, Le Creuset enamel is a non-toxic coating that does more to keep your cast-iron cookware from harming you than it is toxic itself.

A Le Creuset enamel product is safe to use on a glass hob or in an oven and can even be washed in the dishwasher without increasing the risk of toxicity.

How can kitchen utensils be toxic?

As mentioned above, even if Le Creuset enamel is safe, it's not crazy to worry about the toxicity of your cookware. The main problem is that with some protective layers of materials, such as e.g. B. Non-stick coatings, the high temperatures used in cooking can cause this protection to wear off over time.

Once that happens, there is very little to prevent toxins from the heavy metals that make up cookware from leaking out and getting into your food. This, in turn, causes you to absorb these toxins, which can lead to health problems.

Let's go through some of the harmful chemicals that can leak into food from cookware so you can determine just how much Le Creuset enamel is in...if any!

perfluorooctanoic acid

PFOA is one of the key chemicals used to create that non-stick surface on ceramic cookware we all love, and has actually been found to be a harmful toxin when enough of it is added to our chemical makeup by getting into our food is leached. PFOA can cause diabetes, increased risk of cancer, allergies and other problems.


Cadmium is a particular concern when it comes to coating Le Creuset products. Cadmium can lead to faster vision loss due to aging, diabetes, and inflammation, among other things. However, Le Creuset does not use enough cadmium in its enamel coating to cause these harmful symptoms.


All people can handle a small amount of aluminum, but an excessive amount from an aluminum pot or other cookware can put you at increased risk of microcytic anemia, allergic reactions, and osteomalacia. Luckily, Le Creuset's cast iron products, which include their enamel coating, do not contain aluminum!


This chemical is commonly found in non-stick pans and saucepans. It is typically released in the form of toxic fumes when cookware covered with it is exposed to a cooking temperature in excess of 370 degrees. It can lead to polymer fumes, but luckily Le Creuset doesn't contain any traces of this chemical in its enamel coating!

To lead

This point is particularly important to discuss since lead is used in some enameled cookware. It's great for increasing the durability of this type of cookware, but unfortunately, lead can cause kidney failure, colic, muscle pain, and even peripheral neuropathy.

Finally, small amounts of these toxins can get into food when exposed to high temperatures without proper protective coatings in place as a result of toxic fumes. When there are toxins in our food, it doesn't take long for them to enter our bodies.

Fortunately, however, Le Creuset enamel has been tested and is free of lead and cadmiumCalifornia Proposition 65-Standards, which we will see below. In addition, Le Creuset assures its customers that their enamel coatings contain no PFAs or polytetrafluoroethylene chemicals.

When we hear or read the words ceramic nonstick, aluminum cookware, aluminum core, health issues, and birth defects, we really want to address the health risks. With that in mind, check out my article for the types of cookware that are the safest options.What is the safest kitchen utensil?

What is California's Proposition 65 standard?

California's Proposition 65 standard is a type of test used to measure toxicity found in everything from a cast-iron skillet to a Dutch oven. It is sometimes referred to as "Proposition 65" for short. It doesn't technically apply to states outside of California, but it's a great standard for any type of cookware!

California's Proposition 65 standard tests whether a product contains lead or cadmium and, if so, measures the amount of each component that is part of the product. For example, Prop 65 allows less than 0.1 micrograms per milliliter to leach out in a 4% acetic acid solution.

On the other hand, only 0.0049 micrograms may be leached in one milliliter of cadmium in 4% acetic acid solution. If that amount is exceeded in either case, California Proposition 65 issues a warning label that by law must be placed on product packaging.

The fact that Le Creuset cookware has a California Proposition 65 standard means it doesn't contain any of the toxins harmful to humans, as mentioned above, and won't infect your food with harmful chemicals!

Is there something dangerous in Le Creuset enamel?

Therefore, we have firmly established that between the California Proposition 65 standard they achieve and the benefits of enamel coating heavy metals in cookware, there is little to no risk of toxins entering your food when using a Le Creuset enamel product .

However, that begs the question: even though toxins can't get into your food, is there anything unsafe about Le Creuset Enamel?

The only potential hazard you face when cooking with Le Creuset enamel cookware isn't from toxins, it's from flaking enamel. Enamel chips only occur when a Le Creuset product has been damaged. If you drop, scrape or scrape your Le Creuset pot or pan, the enamel coating may crack in certain areas.

When this happens, the structural integrity of the enamel is compromised and more liquid glass sealant that was once fully in your food can begin to flake off. This may result in you ingesting the polish yourself.

As long as you don't notice chips or scratches as a result of a damaged Le Creuset cookware, you probably don't have to worry about accidentally eating that helpful enamel coating! There are also a few ways to reduce the risk of chipping and chipping:

clean properly

A cast iron cookware should be cleaned with a soft sponge or even a cloth rather than rough tools that can damage the enamel finish and cause chipping.

Do not store food in it

After a filling meal, it's tempting to just stick the same pot you used to cook the meal in the potfridge overnight. However, this is not recommended, since the moisture in the refrigerator, as well as the moisture that accumulates when food is cooled, can shorten the life of the enamel coating.

Avoid high temperatures

This might sound like it defeats the purpose of using Le Creuset products, but remember that cookware can still be used to bake or simmer products.

frequently asked questions

If you're still wondering about Le Creuset enamel, toxicity, and options, don't worry! Below we have answered some of the most frequently asked questions on these topics.

What is Le Creuset enamel made of?

Le Creuset's colorful cast iron cookware is coated with a proprietary blend of enamels. The enamel itself is also referred to as "porcelain enamel". Not only does it add a beautiful shine to any cookware, it also helps the product to withstand impact if dropped or bumped and also acts as a protective layer against rust or the penetration of metal toxins.

Le Creuset's enamel coating is made of glass that is sputtered to an incredibly fine grain. This powder is fired at a temperature of up to 850 degrees Celsius! Once this is done, the powder melts into a kind of liquid.

This liquid form allows you to seal something like a pot or pan smoothly, evenly, and most importantly, throughout! Made from a non-toxic thin glass liquid, Le Creuset glaze is extremely beneficial in preventing oxidation of your product and toxins from the food you prepare!

Is Le Creuset really non-toxic?

It might be hard to believe, especially when you notice the Le Creuset company's trademark colorful pots and pans, but Le Creuset products are actually non-toxic! This is evidenced by the fact that they comply with the California Proposition 65 standard.

As mentioned above, achieving this standard means manufacturers don't use harmful chemicals that can find their way into food, particularly lead and cadmium. In addition, Le Creuset has assured customers on its website that its products do not contain other compounds commonly used in non-stick cookware, such as polytetrafluoroethylene or perfluorooctanoic acid.

Do Le Creuset frying pans contain LEDs?

In addition to lead-free cast iron cookware and lead-free stainless steel products, the pans created by Le Creuset are also completely lead-free. This can be tested by the California Proposition 65 standard mentioned above, which is designed specifically to test for harmful levels of lead. Every Le Creuset frying pan meets this standard, meaning it is lead-free.

Does Le Creuset contain heavy metals?

Like all iron cookware, Le Creuset contains very small traces of heavy metals. These heavy metals include nickel, lead, cadmium and chromium. However, as mentioned in our article, this does not mean that Le Creuset pots and pans are poisonous.

In fact, the amount of these metals detected in Le Creuset products is so small that they do not pose any risk to the health of human owners, even with prolonged use. Also, products coated with a layer of Le Creuset enamel can reduce the risk of iron and other heavy metals leaching into food.

Is Scratched Enamel Cookware Safe?

Enamel is very fine glass that liquefies and spreads as a uniform seal on heavy metal products. Therefore, it is possibly the least toxic and safest way to buy cast iron cookware like Le Creuset products. However, as mentioned above, Le Creuset has a weakness and it will chip or peel!

They can chip and flake off when enameled cookware is damaged. This damage can occur when tooth enamel is weakened by exposure to high temperatures, little cold, or too much condensation and steam from improperly stored hot foods. Something like this weakens the enamel layer to the point where it's easily scratched.

The glaze may also begin to chip after being scratched during the firing process. As soon as a scratch occurs, the seal of the enamel coating is broken and it can begin to flake off, leaving particles in the food. This is not safe and may pose health risks. See the care tips above for the best way to avoid this!

Conclusion: Is Le Creuset Enamel Toxic?

In summary, Le Creuset enamel is not itself toxic. In fact, it acts as a sealant that prevents iron and other harmful materials like lead from penetrating food.

Le Creuset enamel is free from harmful chemicals due to the way it is made and meets California's Proposition 65 standard.

Together, Le Creuset enamel is a great way to protect the integrity of your food and your cast iron skillets and stainless steel pots!
