Chocolate brown HT

Chocolate Brown HT (CAS 4553-89-3), also known as E155 and C.I. Food Brown 3, is a synthetic azo dye approved for use as a colorant in food and industrial applications.

It delivers a distinctive warm brown hue across a range of formulations and substrates, where consistent color performance and regulatory compliance are primary sourcing considerations.

In food manufacturing, E155 is used to color products such as biscuits, sauces, and seasonings where a rich brown appearance is required for the final consumer product.

Textile processors apply it to achieve uniform brown shades on natural and synthetic fibers, particularly in batch dyeing operations where color stability is essential for quality.

In leather finishing, it contributes to surface color consistency across hides and treated materials. Printing ink formulators incorporate it into packaging inks for various uses.

Chocolate Brown HT is supplied as a powder or granule, with particle size and solubility characteristics varying by grade to meet specific manufacturing requirements and processes.

Food-grade material is available to specifications aligned with E155 regulatory requirements under EU food additive standards to ensure safety and compliance for manufacturers.

Technical-grade material is offered for textile, leather, and industrial ink applications where food compliance is not required but high performance is still expected.
