Can Tartrazine be used to produce green tablet coatings?
Yes — Tartrazine (yellow) blended with Brilliant Blue FCF (blue) produces green shades. The exact shade of green depends on the ratio: more Tartrazine gives a yellow-green (lime); more Brilliant Blue gives a teal or forest green. This combination is the standard way to achieve green in aqueous film coating systems.
Is Tartrazine approved for pharmaceutical use in India?
Yes. Tartrazine is listed in the Indian Pharmacopoeia (IP) and is an approved pharmaceutical colourant in India. It is also approved as FD&C Yellow No. 5 (USA) and E102 (EU). Products containing Tartrazine must declare it on labels in most markets due to allergen disclosure requirements.
What is the difference between Tartrazine and Sunset Yellow?
Tartrazine (E102) produces a lemon-yellow colour and is the more yellow of the two. Sunset Yellow (E110) produces an orange-yellow shade. Tartrazine is preferred when a clean, bright lemon yellow is needed. Both are azo dyes and behave similarly in terms of pH stability and compatibility with coating systems.
What concentration of Lake Tartrazine is used in HPMC film coatings?
Lake Tartrazine is typically used at 0.5–4.0% w/w of the total coating formulation weight. In standard HPMC-based colour coating systems with TiO₂ as the opacifier, Tartrazine Lake at 1–2% gives a vivid yellow tablet with good colour uniformity and batch-to-batch consistency.
