Indigo Carmine Supplier in Malaysia
- Also known as
- FD&C Blue No. 2
Indigo carmine supplier for food, pharmaceutical, feed and laboratory buyers in Malaysia. Also identified as FD&C Blue No. 2, this dark blue water-soluble colourant is selected by grade, colour strength, purity controls and its behaviour in the intended formulation.
Food-grade indigo carmine colours selected beverages, confectionery, fillings and dry mixes, while pharmaceutical and nutraceutical grades serve tablet, capsule, coating and liquid formulations. Feed-grade material addresses animal and aquaculture colour requirements, and laboratory grades support indicator and analytical work.
The product is supplied as dark blue to blue-violet powder or granules that form a deep blue aqueous solution. Buyers commonly set colour strength, dye content, moisture, insoluble matter, subsidiary-colour and trace-impurity limits rather than ordering by colour name alone.
Send the required grade, specification, application, quantity and delivery location with your enquiry. Availability, packing, documentation, delivery timing and the indigo carmine price are confirmed with the quotation, which carries a stated validity period.

Common questions about indigo carmine
Is indigo carmine the same as indigo pigment?
No. Indigo carmine is a water-soluble blue dye, while indigo pigment is largely water-insoluble and used through dispersion rather than simple dissolution. Their colour behaviour and process requirements differ, so the two should not be substituted by name alone.
Is FD&C Blue No. 2 another name for indigo carmine?
Yes, FD&C Blue No. 2 identifies indigo carmine within a specific colourant naming and grade framework. Buyers should still state the application and required standard because a food, pharmaceutical, feed or laboratory grade is not defined by the alternate name alone.
How do food, pharmaceutical and feed grades differ?
They may use different purity, trace-impurity, microbiological, documentation and use requirements even when the colourant identity is the same. State the finished application and complete quality specification so the appropriate grade can be considered. Supply is subject to applicable requirements.
What specifications should an indigo carmine buyer provide?
Include colour strength, dye content or purity basis, shade, moisture, water-insoluble matter, subsidiary-colour limits and any relevant trace impurities. For solution use, state the target concentration and clarity requirement as well.
Can indigo carmine be prepared as an aqueous solution?
Indigo carmine is water soluble and is commonly dissolved before use. Concentration, water quality, pH and the presence of oxidising or reducing ingredients can affect the observed shade and stability, so test it in the actual formulation and state the solution requirement in the enquiry.
What information is needed for an indigo carmine price quotation?
Provide the grade, colour strength and purity specification, intended use, quantity and delivery location. Mention preferred packing and required documents so availability and commercial details can be confirmed with the quotation.
