What shades does Ponceau 4R produce in tablet coatings?
Ponceau 4R produces a bright strawberry to scarlet red in tablet film coatings. It is an azo dye with good pH stability (stable at pH 2–9), making it suitable for coatings applied over a wide range of tablet formulations. Combined with Yellow Iron Oxide or Sunset Yellow, warm orange-red shades are achieved.
Is Ponceau 4R approved for pharmaceutical use in India?
Yes. Ponceau 4R is listed in the Indian Pharmacopoeia and approved for use in pharmaceutical oral dosage forms in India. It is also approved as food colourant E124 in the EU. Note that it is not approved for use in the USA (not an FD&C colour), which matters for export formulations.
What is the dye content specification for pharma grade Ponceau 4R?
Pharma grade Ponceau 4R (dye form) should have a dye content of NLT 85% on an anhydrous basis. Lake Ponceau 4R typically contains 15–40% dye on an aluminium hydroxide substrate. COA from the manufacturer specifies exact dye content and heavy metal limits.
Why is Lake form preferred over dye form for tablet film coatings?
Lake pigments are water-insoluble and do not migrate through the coating film or bleed into adjacent layers during processing. Dye forms can migrate when coating systems contain water, causing uneven colour or shade variation. Lakes also provide better light stability and are preferred for all solid dosage form colouring.
