Acid Green 50

Acid Green 50 (CAS 3087-16-9), also known by its food additive designation E142, is a synthetic green colorant approved for use across food, textile, and industrial applications. It delivers a bright, stable green hue that resists fading under standard processing conditions, making it a reliable choice for manufacturers requiring consistent color output.

In food and beverage production, E142 is used to color confectionery, desserts, canned vegetables, and beverages where a vivid green appearance is required for the final product. Textile dyeing operations use Acid Green 50 to achieve uniform coloration on wool, silk, and nylon fabrics through specialized acid dyeing processes used in large scale manufacturing.

In printing and packaging, it is incorporated into inks and coatings where precise color matching to green shades is critical for brand consistency and visual appeal. Leather finishing operations also use it to produce consistent surface color on treated hides, ensuring that the final leather goods meet strict aesthetic requirements for the market.

Acid Green 50 is typically supplied as a powder or granule. Food-grade material is available to E142 specification, meeting purity requirements set by relevant food additive regulations. Technical-grade material is supplied for textile, leather, and printing applications where food compliance is not required, providing a cost-effective solution for industrial users.
