Carthamus yellow is a natural colorant derived from the safflower plant (Carthamus tinctorius). It typically appears as a bright yellow to orange-yellow powder or liquid, depending on its formulation. This vibrant hue is striking and is often used to enhance the visual appeal of various products.

The scent of carthamus yellow is generally mild and subtle, lacking the strong aroma associated with some other natural colorants. Its neutral fragrance makes it suitable for applications in food and cosmetics, where the sensory experience is essential but should not overpower the product's other scents.

Carthamus yellow is primarily utilized as a natural dye in the food, cosmetic, and textile industries. In food products, it serves as a coloring agent, enhancing the appearance of items like cheeses, baked goods, and beverages while being considered safe for consumption. In cosmetics, it is used for its coloring properties and may also possess some antioxidant benefits, contributing to skin health. Additionally, in textiles, carthamus yellow provides a vibrant color to fabrics, ensuring they maintain their brightness and appeal over time, while being a more environmentally friendly alternative to synthetic dyes.
