Red 40 is a common food dye that gives many foods and drinks their bright red color.
You may have seen it listed on ingredient labels, but what exactly is it made of?
Red 40 is made from petroleum byproducts through chemical reactions between specific types of acids. It’s not a natural ingredient, but rather a synthetic color additive created in labs.
The main components are sodium salts that create the vivid red hue.
This artificial dye is widely used in the United States and approved by the FDA.
In Europe, it’s known as Allura Red AC and is also allowed in foods.
While generally considered safe, some people worry about potential health effects of Red 40.
It’s good to know what’s in our food so we can make informed choices about what we eat.
What Is Red 40?
Red 40 is a widely used synthetic food coloring.
It gives many foods and drinks their red hue.
This dye comes from petroleum and goes through careful processing before use.
Chemical Composition
Red 40 is an azo dye.
This means it has a special chemical structure with nitrogen atoms.
Its full name is Allura Red AC.
The dye’s main part is made of carbon, hydrogen, oxygen, nitrogen, and sulfur atoms.
Red 40 is water-soluble.
This lets it mix well in foods and drinks.
It’s a dark red powder when dry.
In liquid form, it has a bright red color.
Manufacturing Process
Making Red 40 starts with naphthalene.
This comes from crude oil or coal tar.
The process involves several chemical steps:
- Sulfonation: Adding sulfur groups to make it water-soluble
- Nitration: Adding nitrogen groups
- Reduction: Changing some chemical bonds
- Diazotization: Creating a reactive form
- Coupling: Joining with other molecules
Each step needs careful control.
The result is pure Red 40 dye.
Common Names and Identifiers
Red 40 goes by several names:
- Allura Red AC
- FD&C Red No. 40

It has a unique “E number” for food additives: E129.
This helps identify it on labels.

But they keep checking new studies.
They want to make sure it stays safe for everyone.
Some studies on animals raised concerns.
These tests used very high doses of Red 40.
People don’t usually eat that much.
More research is needed.
Scientists want to know if small amounts over a long time could cause problems.
For now, people can choose if they want to eat Red 40 or not.
Reading labels helps them make this choice.
Regulatory Perspective
Red 40 faces different rules in the USA and Europe.
These rules aim to keep food safe while allowing some use of this color.
FDA Regulations
The U.S. Food and Drug Administration (FDA) allows Red 40 in foods and drinks.
They see it as safe when used correctly.
The FDA sets limits on how much can be used.
Companies must follow strict rules when using Red 40.
They need to get FDA approval for each batch.
This is called batch certification.
The FDA also sets an Acceptable Daily Intake (ADI) for Red 40.
This helps people know how much is okay to eat each day.
European Standards
Europe has stricter rules for Red 40.
The European Food Safety Authority (EFSA) reviews food colors carefully.
In some European countries, foods with Red 40 need a warning label.
This label tells people the color might affect kids’ behavior.
The European Union allows Red 40 but watches its use closely.
They have their own ADI, which might be different from the FDA’s.
Europe also requires more testing of food colors.
They want to make sure these colors don’t cause health problems over time.
Daily Intake and Exposure
Red 40 is found in many foods and drinks.
The amount people eat varies based on diet and age.
Experts have set safe limits for daily intake.
Calculating ADI
The acceptable daily intake (ADI) for Red 40 is 7 milligrams per kilogram of body weight.
This means a 150-pound adult could safely consume 477 mg per day.
For kids, the amount is lower based on their size.
To figure out your ADI:
- Find your weight in kilograms
- Multiply by 7
It’s hard to know exactly how much Red 40 is in foods.
Labels don’t list amounts.
But staying under the ADI is easy for most people who eat a varied diet.
Common Sources of Red 40
Red 40 is in many processed foods.
It gives color to candy, drinks, cereals, and snacks.
Some surprising places it shows up:
- Medications
- Cosmetics
- Dairy products like yogurt
- Baked goods
Kids often eat more Red 40 than adults.
They like brightly colored foods and drinks.
Reading labels can help spot Red 40.
It may be listed as:
- FD&C Red No. 40
- Allura Red AC
- Red 40 Lake
Cutting back on processed foods lowers Red 40 intake.
Choosing natural food colors is another option.
Natural vs. Synthetic Dyes
Food dyes come in two main types: natural and synthetic.
Natural dyes use plant or animal sources, while synthetic dyes are made in labs.
Each type has its own pros and cons for food coloring.
Benefits of Natural Dyes
Natural dyes offer some perks over synthetic ones.
They come from plants like berries or other natural sources.
This makes them appealing to people who want to avoid artificial additives.
Natural dyes are often gentler on the body.
Some folks have fewer allergic reactions to them.
They can be a good choice for those with sensitivities.
Another plus is that natural dyes may have health benefits.
For example, some contain antioxidants.
These can help protect cells from damage.
Natural colors can give food a more authentic look.
They often create softer, more muted shades.
This can make food seem less processed.
Comparison with Synthetic Dyes
Synthetic dyes like Red Dye 40 have some advantages over natural ones.
They tend to be brighter and more stable.
This means they keep their color better over time.
Synthetic dyes are usually cheaper to make.
They’re also easier to produce in large amounts.
This makes them popular with food companies.
But synthetic dyes can have downsides.
Some studies link them to health issues.
For example, they might cause allergic reactions in some people.
Natural dyes can be less consistent.
Their color can change based on factors like pH or heat.
Synthetic dyes are more reliable in different conditions.
Synthetic dyes often last longer in food.
This can be good for shelf life but may raise concerns about artificial ingredients.
Understanding Food Labels
Food labels help shoppers know what’s in their food.
They list ingredients and show if Red 40 is used.
Different countries have their own rules for food labels.
Identifying Red 40
Red 40 goes by many names on food labels.
In the United States, it’s often listed as “Red 40,” “FD&C Red No. 40,” or “Allura Red AC.” The FDA requires it to be clearly shown on ingredient lists.
Look for these names when checking labels:
- Red 40
- FD&C Red No. 40
- Allura Red AC
Red 40 is common in many processed foods.
It’s used in candy, drinks, and even some medicines.
Always check labels if you want to avoid this dye.
Global Labeling Differences
Different countries have different rules for food dyes.
In Europe, Red 40 is known as E129.
European labels must warn that E129 “may have an adverse effect on activity and attention in children.”
The United States doesn’t require this warning.
But the FDA does make companies list Red 40 on labels.
Some U.S. food makers are switching to natural colors due to consumer concerns.
When traveling, be aware that familiar foods might have different ingredients.
Always check labels, even on products you know from home.
