Brilliant Black BN

Brilliant Black BN (CAS 2519-30-4), also known as Black PN and approved as E151, is a synthetic azo dye used to impart deep black and dark brown-black coloration in food, textile, and leather applications.

Where is Brilliant Black BN used?

• Food: colorant in confectionery, sauces, fish roe analogues and soft drinks requiring true black or near-black appearance
• Textile: dyes wool, silk and nylon, effective where uniform dark shades and acceptable wash fastness are specified
• Leather: dyeing and coating formulations for consistent black tones on finished hides
• Paper: specialty colored paper grades where deep black coloration is part of the product specification
• It functions as a colorant in aqueous and formulated systems, delivering strong tinctorial strength at low use levels.

Good to know: Food-grade material meets E151 specifications under EU colorant regulations; purity requirements govern subsidiary dyes and heavy metal limits. Technical grades are available for textile and leather end uses where food compliance is not required.
