Is Allura Red approved in both India and the USA for pharmaceutical products?
Yes. Allura Red is one of the most globally permitted synthetic red dyes. It is approved as FD&C Red No. 40 in the USA, E129 in the EU, and is listed in the IP for pharmaceutical use in India. This makes it the preferred red dye for formulations destined for multiple markets.
What is the difference between Allura Red and Ponceau 4R for tablet coatings?
Both produce red shades, but Allura Red is permitted in more markets (including USA) while Ponceau 4R is not approved in the USA. Allura Red produces a slightly more orange-red than the brighter scarlet of Ponceau 4R. For export formulations targeting the US market, Allura Red is the required choice.
What concentration of Allura Red Lake is used in tablet film coatings?
Lake Allura Red is used at 0.5–3.0% w/w in tablet coating formulations. Combined with TiO₂ (for opacity) and a coating polymer (HPMC or Opadry), it produces uniform, vivid red tablets. The exact concentration depends on the depth of shade required and the tablet surface area.
Is Allura Red stable in HPMC aqueous coating systems?
Yes. Allura Red is stable at pH 3–9, thermally stable up to 120°C, and resistant to light fading under normal packaging conditions. It is fully compatible with standard aqueous HPMC coating systems including Opadry, Sepifilm, and similar commercial coating systems.
