Skittles Ingredients: What’s Inside the Rainbow (2026)

Last reviewed: October 2026. Reflects the current U.S. Skittles Original label; the bag photographed for this post is the 2.17 oz size. Titanium dioxide, which was on the label for years, has been removed from U.S. Skittles as of 2025; the dyes remain in the store bag. A version without synthetic dyes has been sold online since August 2026.

Skittles is the product that made “food dyes” a dinner-table topic. In 2022 a lawsuit over titanium dioxide produced the headline that Skittles were “unfit for human consumption”; in 2023 a California bill was misreported as a “Skittles ban”; in 2025 Mars quietly removed the titanium dioxide and kept everything else; and in 2026 it began selling a dye-free version online while the store bag stayed the same. Everything else is five synthetic dyes, two kinds of sugar, a hydrogenated oil, and a wax. Here’s all the Skittles ingredients, what each one does, what actually happened with the bans, and what the research says about the dyes.

Quick answer: what’s in Skittles?

The full Skittles ingredients list

Three things to notice. The first three ingredients — two sugars and a hardened oil — are essentially the whole bag; everything after “less than 2%” is flavor, color, and shine. The dyes appear nine times because each one is listed in two forms: the water-soluble dye for the chewy center, and the “lake” (the dye bonded to aluminum) for the candy shell. And there’s no fruit anywhere on the label: the flavor is “natural and artificial flavors,” and the rainbow is five petroleum-derived colors.

Skittles ingredients explained

Sugar Flagged

Sucrose, the first ingredient by weight. Together with the corn syrup below it makes up 45 g per bag — all of it added sugar, 90% of the FDA’s daily value in one small bag and more than a 12 oz Coke. Candy sugar is absorbed slightly slower than liquid sugar because you chew it, but at this dose the distinction is thin. Daily intake at this level is linked to weight gain, type 2 diabetes, and tooth decay across the research. Our sugar and corn syrup breakdown covers the science.

Corn syrup Flagged

Regular corn syrup (mostly glucose), not high fructose corn syrup. In candy its job is texture: it prevents the sugar from crystallizing, which is what makes Skittles chewy rather than crunchy. Nutritionally it’s sugar; the two are counted together above.

Hydrogenated palm kernel oil Low concern, worth knowing

The fat that gives the shell its snap and keeps the center from going sticky. “Fully hydrogenated” oil is solid and contains essentially no trans fat (the partially hydrogenated kind, which did, was banned by the FDA in 2018). What it does contain is saturated fat: 2.5 g per bag, about 12% of the daily value. Minor for a treat; it’s the reason the bag has fat in it at all. Starburst, Skittles’ sister candy, uses the same oil.

Citric acid Fine

The sour note, and a mild preservative. Same molecule as in citrus fruit. It’s also part of why Skittles are hard on teeth: sugar plus acid, chewed, sticks to enamel longer than a drink does.

Tapioca dextrin and modified corn starch Fine

Starches that form the shell and bind the glaze. “Modified” means processed for a specific texture, not genetically modified. No concern.

Natural and artificial flavors Undisclosed

The fruit flavors — strawberry, orange, lemon, green apple (lime until 2013, back as a separate product since 2021), grape. All from flavor compounds, none from fruit. “Artificial” means some are synthesized; chemically that’s not a safety distinction. The reason every Skittle tastes like its color is the color; blindfolded tests consistently find people can’t tell the flavors apart.

Sodium citrate Fine

An acidity regulator balancing the citric acid. Trace amount.

Carnauba wax Fine

Palm-leaf wax from Brazil, the same thing in car polish and lipstick, used in a tiny amount to make the shell shiny. Indigestible, inert, and plant-based. It’s the one ingredient that sounds alarming and isn’t at all.

The five dyes

Red 40, Yellow 5, Yellow 6, Blue 1, and Blue 2 — five of the six synthetic dyes on the FDA’s 2025 phase-out list, in one bag. M&M’s carry the same five. Three of them (Red 40, Yellow 5, Yellow 6) were in the 2007 Southampton trial, the randomized study that found dye mixtures increased hyperactivity in children from the general population, and all three carry a child-behavior warning label in the EU. That warning is why Skittles sold in Europe are colored with paprika, spirulina, and black carrot extract instead — same brand, same shape, different label, because the company would rather reformulate than print the warning. The two blues weren’t in the Southampton study and have less evidence against them; they’re on the phase-out list by association.

Mars, which makes Skittles, has a long history with this. It pledged in 2016 to remove artificial colors from its products, walked that back in 2021, and through mid-2025 was the most prominent holdout as other big food companies signed on to the FDA’s phase-out. In July 2025 it changed course partway: it announced dye-free “options” for Skittles Original, M&M’s, Starburst Original, and Extra Spearmint, sold online in addition to — not instead of — the regular products. Those launched in August 2026. For M&M’s, Mars has said it aims to have every color natural by 2028; for Skittles it hasn’t announced a date to change the store bag, and the one photographed for this post, best by November 2027, still lists all five dyes. The state bans will force the issue regardless: California’s school-food ban takes effect December 31, 2027, and West Virginia’s statewide ban on January 1, 2028. Our Red 40 breakdown covers the behavioral research and the full timeline; the synthetic food dyes hub covers the other four.

The “Skittles ban” and titanium dioxide

Three things got tangled together in the headlines, and none of them was a ban on Skittles.

• The 2022 lawsuit. A California class action argued Skittles were “unfit for human consumption” because they contained titanium dioxide, a whitening pigment the EU banned in food in 2022 over unresolved questions about whether nanoparticles accumulate in the body. The suit was voluntarily dropped a few months later. Titanium dioxide remains FDA-approved.
• The 2023 “Skittles ban.” California’s AB 418, reported everywhere as the Skittles ban, originally included titanium dioxide — and then removed it before passage. The final law bans Red 3, brominated vegetable oil, potassium bromate, and propylparaben from 2027. Skittles contain none of them. Skittles were never banned in California or anywhere else in the U.S.
• The 2025 reformulation. Mars removed titanium dioxide from U.S. Skittles anyway, confirming it in May 2025. If your bag still lists it, it’s old stock. The five dyes are unchanged in the store bag.

The honest summary: the ingredient the lawsuit was about is gone, the ingredient the law was about was never in them, and the ingredients with the best evidence of harm — the sugar and the dyes — were never the subject of either.

Skittles nutrition facts

Starburst figures are scaled from its 6-piece (29 g) label to the 2.07 oz single pack. Gram for gram, Skittles are the most sugar of the three — about 73% sugar by weight — because there’s no chocolate or extra fat displacing it.

Are Skittles bad for you?

The concerns, ranked by evidence:

1. Sugar. 45 g per bag, 90% of the daily value, nearly double a child’s daily limit.
2. Teeth. Sugar plus citric acid, chewed and stuck to enamel. Sticky candy is the dentist’s worst case.
3. The dyes in children. Randomized-trial evidence of a modest hyperactivity effect in some kids; five dyes at once; being phased out by law in several states.
4. Saturated fat. 2.5 g from the palm kernel oil; minor.
5. Everything else. Dextrin, starch, wax, citrate: no meaningful evidence of harm.

Skittles for kids, vegans, and allergies

Kids: the product most of the dye research is effectively about. If a child seems to react to brightly colored foods, this is the first thing to cut, and there’s no nutritional cost to doing it.

Vegans: U.S. Skittles Original are vegan by ingredient since Mars dropped gelatin in 2010 and carmine earlier; the sugar may be processed with bone char, which some vegans count. Carnauba wax is plant-based. Starburst, by contrast, still contains gelatin in the U.S.

Allergies: no milk, egg, nuts, soy, wheat, or gelatin in Original; the bag is labeled gluten-free and gelatin-free, and “contains bioengineered food ingredients” (the corn syrup and starch). Yellow 5 is the one dye with documented sensitivity reactions (hives, asthma) in a small number of people, which is why it’s required to be named on labels.

Cleaner alternatives

For Skittles without the dyes: Mars’s own dye-free Skittles, sold online since August 2026, or the European version, which shows up in import shops. For fruit chews without synthetic dyes from other brands: YumEarth and Black Forest organic fruit snacks use fruit and vegetable colors; SmartSweets cuts the sugar as well (stevia and allulose, 3 g per bag). Welch’s Fruit Snacks have no dyes either, though most of their sugar is still added. Otherwise: a small bag, not a share size, and not every day.
