What makes Quinoline Yellow different from Tartrazine for yellow tablet coatings?
Quinoline Yellow (E104) produces a distinctly greenish-yellow shade, whereas Tartrazine (E102) gives a purer lemon-yellow. Quinoline Yellow is preferred when a yellow-green or chartreuse tone is specifically required. It also has a slightly different regulatory profile — it is not approved in the USA as an FD&C colour, so formulations for the US market cannot use it.
Is Quinoline Yellow approved for use in India?
Quinoline Yellow is listed in the IP and permitted as a pharmaceutical colourant in India. In the EU it is approved as E104 for food and pharmaceuticals. It is not approved for food or pharmaceutical use in the USA. Always verify regulatory status for the target market before using in export formulations.
What are the specifications for pharma grade Quinoline Yellow?
Pharma grade Quinoline Yellow dye should have a dye content of NLT 70% (as it is a mixture of monosulphonate and disulphonate). Lake Quinoline Yellow contains 15–40% dye on an aluminium hydroxide substrate. Heavy metal limits and microbiological specs must meet IP/BP/EP requirements.
Can Quinoline Yellow be used in oral liquid pharmaceutical formulations?
Yes. Quinoline Yellow dye is water-soluble and used in oral syrups, elixirs, and liquid preparations at 0.005–0.015% w/v concentration. It provides good colour intensity at low concentrations and is compatible with most pharmaceutical excipients used in oral liquids including sucrose, glycerin, and sorbitol.
