What is Quinoline Yellow?
Quinoline Yellow, also known by designations such as C.I. 47005 and Food Yellow 13, is a synthetic organic compound that appears as a bright, greenish-yellow powder. It is a mixture of the sodium salts of the mono- and disulfonic acids of 2-(2-quinolyl)-1,3-indandione. Its water-soluble nature makes it exceptionally easy to incorporate into a vast array of liquid and solid formulations, providing a stable and vibrant yellow hue that is both reliable and visually appealing. The compound is valued for its consistency and performance across different applications.

Diverse Applications Across Industries
The utility of Quinoline Yellow is remarkably broad, making it an indispensable ingredient in several key industries.

1. Food and Beverage Industry:
In the food sector, visual appeal is paramount. Quinoline Yellow provides a brilliant and stable yellow color to a wide range of products. It is commonly used in confectionery such as candies and jellies, baked goods, soft drinks, powdered drink mixes, dessert products, and sauces. Its stability under various processing conditions, including heat and light, ensures that the final product maintains its intended appearance throughout its shelf life. For any food processor looking to buy a reliable food-grade colorant, our Quinoline Yellow is an excellent choice.

2. Pharmaceutical Industry:
Color plays a critical role in pharmaceuticals for identification and patient compliance. Different dosages or types of medication are often color-coded to prevent errors. Quinoline Yellow is approved for use in many regions as a colorant for ingested drugs, such as tablets and capsules. Its use helps in easy differentiation of products, enhancing safety and brand recognition. Pharmaceutical companies looking for a consistent and high-quality excipient will find our product meets their exacting requirements. We are a trusted supplier to numerous pharmaceutical firms.

3. Cosmetic and Personal Care Industry:
The cosmetic industry relies heavily on a vibrant palette to create appealing products. Quinoline Yellow is used in a wide variety of cosmetic formulations, including lotions, soaps, shampoos, bubble baths, and makeup. Its bright hue adds value to products, making them more attractive to consumers. It is approved for use in externally applied cosmetics and is known for its skin safety when used according to regulations.

Beyond consumables, Quinoline Yellow is also an effective dye for textiles, imparting a brilliant yellow to materials like wool, silk, and nylon. Its excellent colorfastness makes it a durable choice for fabrics. It is also used in the production of paper and printing inks, demonstrating its versatility as an industrial colorant.

Safety and Handling
While Quinoline Yellow is widely approved and considered safe for its intended uses, proper handling is essential in an industrial setting. As a fine powder, we recommend using appropriate personal protective equipment (PPE), including gloves, safety glasses, and respiratory protection, to avoid direct contact and inhalation.
