Basic orange II, also known as basic orange 2, Chrysoidine Crystal, Chrysoidine Y. It is a synthetic dye and belongs to the basic dye category. Like Alkaline Orange 2, it is commonly used in the textile industry for dyeing purposes. Chrysoidine Y has a yellow-orange color and good color fastness properties, making it suitable for dyeing a wide range of materials including cotton, wool, silk and synthetic fibers. It is commonly used to produce yellow, orange and brown tones on fabrics. Chrysoidine Y can be used in other applications besides textiles. It is used in the formulation of a variety of products such as inks, paints, and markers. Due to its bright and vibrant color, it is often used to create eye-catching, intense hues. It is important to note that, like other synthetic dyes, the production and use of Chrysoidine Y has environmental impacts. Proper dyeing techniques, wastewater treatment and responsible disposal are necessary to minimize potential negative impacts on the environment. To ensure sustainability, we are conducting research and development focused on developing more environmentally friendly dyeing methods and exploring alternatives to synthetic dyes in industry.
