Red 40 (Allura Red AC): FDA Phase-Out, State Bans & Reformulation Guide

What Is Red 40?

FD&C Red No. 40, known chemically as Allura Red AC (CAS 25956-17-6, UNII: WZB9127XOA), is a synthetic azo dye derived from petroleum that produces an orange-red color in food, drugs, and cosmetics. It is the most widely used certified color additive in the United States, appearing in thousands of products across food, beverage, pharmaceutical, and personal care categories.

Red 40 is authorized under 21 CFR 74.340 for general use in food (including dietary supplements) "in amounts consistent with good manufacturing practice." Batches must be certified by the FDA under 21 CFR Part 80 before commercial use. The dye must meet strict purity specifications: total color content of at least 85%, lead below 10 ppm, arsenic below 3 ppm, and water-insoluble matter below 0.2%.

Red 40 is chemically distinct from FD&C Red No. 3 (erythrosine), which is a fluorone dye already banned by the FDA. Red No. 3's ban was triggered by the Delaney Clause based on animal carcinogenicity data -- a mechanism that does not apply to Red 40, which has not demonstrated carcinogenicity. The regulatory path for Red 40's removal is therefore different: it depends on a voluntary industry phase-out and potential future rulemaking rather than a mandatory Delaney Clause revocation.

FDA Regulatory Status

Red 40 is currently authorized but targeted for elimination by end of 2026. As of this writing, the color additive listing at 21 CFR 74.340 remains in effect. No proposed rule to revoke Red 40's authorization has been published in the Federal Register.

However, on April 22, 2025, the FDA and HHS issued a joint press announcement declaring their intent to eliminate six petroleum-based synthetic food dyes -- including Red 40 -- from the U.S. food supply by the end of 2026. The announcement was part of the administration's Make America Healthy Again (MAHA) initiative.

The April 22 announcement outlined a multi-pronged approach:

1. Voluntary industry phase-out: The FDA called on food manufacturers to substitute petroleum-based dyes with natural alternatives, establishing a national transition timeline with a target of end of 2026.
2. Guidance and regulatory flexibilities: The FDA committed to issuing guidance to facilitate industry reformulation and to streamline the review of natural color additive petitions.
3. Fast-tracked natural alternatives: Four natural color additives were announced for expedited authorization -- calcium phosphate, Galdieria extract blue, gardenia blue, and butterfly pea flower extract. Three of these (Galdieria extract blue, butterfly pea flower extract, and calcium phosphate) were formally approved on May 9, 2025.
4. Formal revocation of two rarely used dyes: The FDA initiated revocation proceedings for Citrus Red No. 2 (21 CFR 74.302) and Orange B (21 CFR 74.250), both of which have minimal commercial use. The Orange B removal was proposed in the Federal Register on September 17, 2025 (FR 2025-18023).
5. NIH research partnership: Collaboration with the NIH Nutrition Regulatory Science and Research Program to study food additives' impact on children's health.

HHS Secretary Kennedy stated: "These poisonous compounds offer no nutritional benefit and pose real, measurable dangers to our children's health and development." FDA Commissioner Makary said the FDA is "asking food companies to substitute petrochemical dyes with natural ingredients for American children as they already do in Europe and Canada."

What "Phase-Out" Means -- and What It Does Not

It is critical to distinguish between the Red 40 situation and the Red No. 3 ban:

• Red No. 3: Formal revocation via final order under the Delaney Clause. Products containing Red No. 3 will be legally adulterated after January 15, 2027 (food) and January 18, 2028 (drugs). This is a hard legal prohibition.
• Red 40: A voluntary phase-out request backed by political pressure and the MAHA initiative, but no proposed or final rule to revoke 21 CFR 74.340 has been published. As of March 2026, Red 40 remains a lawfully authorized color additive. The FDA has signaled that regulatory action will follow if voluntary compliance is insufficient, but no specific rulemaking timeline has been announced.

Companies should plan for removal but understand that the current federal action is guidance-based, not a legal mandate with a fixed compliance date.

State-Level Bans

While federal action remains voluntary, several states have enacted mandatory bans that include Red 40. These laws create a patchwork of hard compliance deadlines that effectively force reformulation for companies with national distribution.

California -- AB 2316 (California School Food Safety Act)

Signed into law on September 28, 2024, AB 2316 prohibits California schools from serving foods containing six synthetic dyes: Blue 1, Blue 2, Green 3, Red 40, Yellow 5, and Yellow 6. The ban takes effect December 31, 2027 and applies to school breakfasts, lunches, and competitive foods sold during school hours. Fundraising events are exempt.

AB 2316 is distinct from California's AB 418 (2023), which banned Red No. 3 and three other additives from all consumer food. Red 40 is not covered by AB 418 -- only by the school-specific AB 2316.

West Virginia -- HB 2354

Signed by the Governor on March 24, 2025, West Virginia's law is the broadest state-level food dye ban in the country. It targets seven synthetic dyes: Red 3, Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2, and Green 3 (plus BHA and propylparaben).

The law has a split timeline:

• August 1, 2025: School nutrition program restrictions take effect
• January 1, 2028: General food adulteration standards apply statewide -- making these dyes effectively prohibited in all food products sold in West Virginia

Sellers with under $5,000/month in sales of affected products face no criminal penalties, though civil enforcement remains available. A federal judge issued a preliminary injunction in December 2025 blocking enforcement of the retail provisions; the school meals ban remains in effect.

Utah -- HB 402

Signed by Governor Cox on March 27, 2025 (effective May 7, 2025), Utah's law bans Red 40 and eight other dyes/additives in school food. School compliance is required for the 2026-2027 school year.

Arizona -- HB 2164

Bans Red 40 and other synthetic dyes in school food, effective for the 2026-2027 school year.

Virginia -- S 1289/H 1910

Bans Red 40 and six other synthetic dyes in school food, effective July 1, 2027.

Pending Legislation

As of early 2026, additional food dye legislation has been introduced in Illinois, New York, Pennsylvania, and other states. More than 15 state-level food chemical bills have been enacted nationwide, with nearly 70 introduced across state legislatures -- a legislative wave amplified by the MAHA movement.

International Status

European Union -- E129

Red 40 is authorized in the EU as E129 under Regulation (EC) No 1333/2008, but subject to significant restrictions:

• Mandatory warning label: Since 2010, any food containing E129 must carry the notice: "may have an adverse effect on activity and attention in children" (Annex V of Regulation 1333/2008). This requirement was adopted following the 2007 Southampton study and applies to E129 alongside five other dyes (the "Southampton Six": E102 Tartrazine, E104 Quinoline Yellow, E110 Sunset Yellow, E122 Carmoisine, E124 Ponceau 4R, E129 Allura Red).
• Maximum permitted levels: E129 is subject to specific use levels per food category under Annex II. It is not permitted at quantum satis (unlimited GMP levels) as it is in the United States.
• ADI: EFSA established an ADI of 7 mg/kg body weight/day in its 2009 re-evaluation, retained in the 2015 review.

The warning label requirement has driven most major European food manufacturers to voluntarily reformulate away from E129 and other synthetic dyes, creating a de facto market-driven phase-out that preceded the U.S. federal action by over a decade.

United Kingdom

Post-Brexit, the UK retains the EU-era warning label requirement for E129 under the Food Standards Agency (FSA) framework. The "Southampton Six" labeling obligation remains in effect.

Canada

Red 40 is permitted as a food colorant in Canada under the Food and Drug Regulations. Health Canada has not imposed mandatory warning labels, though the agency has conducted its own safety reviews. FDA Commissioner Makary specifically cited Canada as a market where companies already use natural alternatives.

Other Jurisdictions

Red 40 is authorized in most countries worldwide. Several European countries -- including Denmark, Belgium, France, Switzerland, Sweden, Austria, and Norway -- have historically imposed additional restrictions or voluntary industry agreements limiting synthetic dyes in products marketed to children, though EU-wide harmonization under Regulation 1333/2008 now governs. Japan permits Red 40 (as Food Red No. 40) with specified use levels.

Affected Product Categories

Red 40 is the single most widely used certified color additive in the U.S. food supply. Companies should audit any product with red, orange, pink, or purple coloring.

Food Products

• Candy and confections -- Skittles, M&M's, Starburst, Swedish Fish, gummy candies, fruit snacks, licorice
• Beverages -- Sports drinks (Gatorade Fruit Punch), sodas (Mountain Dew Code Red), juice drinks (Hawaiian Punch, Kool-Aid), energy drinks, flavored waters
• Cereals and snack foods -- Froot Loops, Fruity Pebbles, Lucky Charms, Flamin' Hot Cheetos, Doritos, flavored chips
• Baked goods -- Strawberry Pop-Tarts, cake mixes, frostings, snack cakes, cookie decorations
• Dairy products -- Strawberry yogurt, flavored milk, ice cream, pudding cups
• Condiments and sauces -- BBQ sauces, hot sauces, salad dressings, flavored syrups
• Frozen foods -- Frozen desserts, flavored ice pops, frozen pizzas with pepperoni coloring

Dietary Supplements

• Gummy vitamins (red/orange/pink varieties)
• Chewable tablets
• Liquid supplements (berry/cherry-flavored)
• Protein powders (strawberry/fruit punch flavors)

Drugs and Cosmetics

• OTC medications (children's cold/flu syrups, chewable analgesics)
• Prescription drug coatings
• Lipsticks, blushes, and other cosmetics (authorized under 21 CFR 74.1340 and 74.2340)

What Companies Should Do

Immediate Actions (Now Through End of 2026)

1. Conduct a full SKU audit. Identify every product containing FD&C Red No. 40, Red 40 Lake, or any color blend that includes Allura Red AC. Include contract-manufactured, private-label, and food service products.

2. Map your state regulatory exposure. If you sell into school food channels, West Virginia's ban is already effective (August 2025). Utah and Arizona follow in the 2026-2027 school year. Companies with national distribution across school foodservice must reformulate now.

3. Prioritize school foodservice and children's products. The strongest regulatory and reputational pressure targets products consumed by children. Reformulate these lines first.

4. Engage reformulation programs. Natural red alternatives include:

   • Beet juice concentrate -- Stable at low pH, good for beverages and confections
   • Red cabbage extract (anthocyanins) -- pH-dependent color range (red to blue)
   • Carmine/cochineal extract -- Excellent stability but requires allergen disclosure per 21 CFR 73.100
   • Paprika oleoresin -- Orange-red, good for savory applications
   • Lycopene -- Tomato-derived, limited shade range
   • Black carrot extract -- Deep red, works well in acidic beverages

   Each alternative has distinct stability, pH sensitivity, cost, shade-matching, and allergen profiles. Reformulation lead times typically run 6-12 months including stability testing and packaging updates.

5. Monitor the Federal Register. No proposed rule to revoke 21 CFR 74.340 has been published yet. When it appears, it will establish a formal comment period and compliance timeline. Companies should be prepared to submit comments and plan for a hard deadline.

6. Track industry commitments. Major manufacturers have announced reformulation timelines:

   • General Mills: Synthetic dyes out of cereals and school food by summer 2026; full U.S. portfolio by end of 2027
   • Conagra Brands: School foodservice products dye-free by 2026-2027 academic year; full U.S. retail by end of 2027
   • JM Smucker (Hostess): Began reformulating snack cakes in January 2025; full brand portfolio by end of 2027

   Companies that delay reformulation risk being left behind as retail and foodservice buyers adopt dye-free procurement standards.

Supply Chain Considerations

• Natural colorant supply pressure: As the industry shifts simultaneously, demand for natural red colorants will surge. Secure supply agreements with colorant suppliers early.
• Cost impact: Color reformulation typically costs $50,000-$200,000 per SKU including stability testing, process adjustments, packaging updates, and label reprinting. Companies with large portfolios face multi-million-dollar programs.
• Dual formulation strategy: Some companies maintain separate formulations for U.S. and international markets. However, given the global trend toward natural colors, a single natural-colorant specification may be more cost-effective long term.

For Pharmaceutical and Supplement Companies

Drug reformulation carries additional regulatory requirements:

• Color changes to approved drugs may require supplemental NDA/ANDA filings
• Stability testing under ICH guidelines (6-12 months accelerated, 24 months real-time)
• The voluntary nature of the current phase-out means no hard FDA deadline exists for drug products, but companies should plan proactively given the political environment
• Dietary supplements follow food timelines and state law applicability
