Alpha-naphthol orange

Alpha-naphthol orange (CAS 2347-72-0), also known as E111 and Orange GGN, is a synthetic azo dye approved for use as a colorant in regulated food and non-food applications.

It imparts a characteristic orange hue to finished products across food manufacturing, cosmetics, and industrial dyeing processes. In food and beverage production, E111 is used to achieve consistent orange coloration.

This dye is utilized where permitted under regional regulatory frameworks. Textile processors apply it in dyebath formulations to color natural and synthetic fibers, where batch-to-batch shade consistency is a key consideration.

In leather finishing, it contributes to surface colorants and topcoat formulations requiring durable, uniform tone. Personal care manufacturers incorporate it into cosmetic preparations such as soaps and bath products.

The material is valued for colorant stability under alkaline conditions. Alpha-naphthol orange is typically supplied as a powder or granule to meet various industrial and commercial manufacturing requirements.

Food-grade material meeting E111 specifications is available for regulated applications, while technical-grade material is sourced for textile, leather, and industrial use for global supply chains.

Buyers should confirm regional approval status and purity specifications, including dye content percentage, prior to procurement. Regulatory acceptance varies by market and specific application requirements.
