How is Brilliant Blue used to make green tablet coatings?
Brilliant Blue FCF is the blue component in the standard green colour blend for tablet coatings. Mixed with Tartrazine (yellow) at varying ratios, it produces the full range of green shades — lime green (more Tartrazine), mid green (equal blend), and dark green (more Brilliant Blue). This is the most reliable way to produce stable green coatings.
Is Brilliant Blue FCF approved for pharmaceutical use in India?
Yes. Brilliant Blue FCF is approved for pharmaceutical use in India as listed in the IP, and it is approved as FD&C Blue No. 1 in the USA and E133 in the EU. It is one of only two blue synthetic dyes approved for widespread pharmaceutical use globally.
Is Brilliant Blue stable in acidic conditions used in tablet coatings?
Brilliant Blue FCF is generally stable at pH 4–8. At pH below 3, some colour shift may occur. In standard pharmaceutical aqueous coating systems (pH 5–7), it is highly stable. The lake form is more stable than the dye across a wider pH range and is preferred for tablet coating.
What is the typical use level of Brilliant Blue Lake in tablet film coatings?
Lake Brilliant Blue is used at 0.1–1.0% w/w in tablet coating formulations. Due to its high tinctorial strength, small amounts produce intense blue colour. For green shades (blended with Tartrazine Lake), even lower amounts of Brilliant Blue are typically used relative to the yellow component.
