Allura Red AC

Allura Red AC (CAS 64553-31-7), also known as E129 and FD&C Red 40, is a synthetic azo dye used to impart red-to-orange coloration across food, pharmaceutical, and cosmetic products.

It is one of the most commercially prevalent certified colorants in global supply chains, approved across major regulatory frameworks including the EU, US, and beyond for various industrial uses.

In food and beverage manufacturing, it colors confectionery, soft drinks, desserts, and snack products where a stable, bright red hue is required at low use levels during the production process.

Pharmaceutical formulators incorporate it into oral solid dosage forms, such as tablets, capsules, and syrups, where consistent color coding supports product identification and patient compliance.

In personal care, it is used in rinse-off and leave-on formulations including shampoos, soaps, and certain cosmetic products requiring a red tone for aesthetic appeal and consumer recognition.

Processed food producers also rely on it for sauces, condiments, and flavored dairy products where heat and pH stability during processing are critical sourcing considerations for quality control.

Allura Red AC is supplied as a fine red powder or granules, with granulated forms preferred where dust control in production environments is a priority for safety and efficiency.

It is available in food-grade certified forms meeting FCC and EU specifications, as well as pharmaceutical-grade material compliant with relevant pharmacopoeial standards for global distribution.
