Brown HT

Introduce reliable brown coloration into industrial and technical formulations with Brown HT Powder (CI 20285, E-155) — a synthetic monoazo dye known for its strong tinting strength and excellent solubility in aqueous systems.

Brown HT produces a rich reddish-brown to chocolate-brown tone depending on concentration and formulation environment. Its molecular structure (C27H18N4Na2O9S2) allows rapid dispersion in water, making it efficient for industrial dyeing, research applications, and non-regulated product development.

Regulatory Status – Critical Compliance Notice

Brown HT (E-155) is approved in certain regions such as the European Union under regulated limits.

However:

• It is NOT listed under FDA-approved color additives (21 CFR Parts 73 & 74).
• It is NOT permitted for use in food, pharmaceuticals, or cosmetics in the United States.
• This SKU is strictly NON-FDA Industrial Grade.

This distinction is essential for regulatory compliance in the U.S. market.

Why Choose Brown HT Powder?

✔ Excellent water solubility
✔ Strong color intensity at low dosages
✔ Uniform dispersion
✔ Stable under standard industrial conditions
✔ Cost-effective bulk coloring solution

Imagine formulating a technical fluid or detergent where visual differentiation is critical — Brown HT provides consistent depth and clarity without affecting base viscosity or performance.

Common Non-Regulated Applications

• Industrial cleaning formulations
• Soap & detergent coloration
• Laboratory tracer solutions
• Textile research applications
• Paper and pulp dyeing studies
• Technical product identification systems

Performance Characteristics

• Soluble in water
• Produces stable brown shades
• Compatible with neutral and mildly acidic systems
• Avoid prolonged exposure to extreme alkaline conditions
• Good heat stability under normal industrial processing

Handling & Safety Guidelines

As a synthetic azo dye:

• Avoid inhalation of dust
• Use gloves and protective eyewear
