Coccinic acid is primarily used in the textile industry as a natural dyeing agent. It imparts red and crimson shades to fabrics, especially when used with mordants like alum or iron. Due to its affinity for protein fibers, it is widely applied in dyeing wool and silk. It also finds use in traditional and artisanal crafts where natural colorants are preferred over synthetic dyes. Additionally, coccinic acid has been explored for its potential in food coloring and as a pH indicator in educational and laboratory settings due to its color-changing properties in different pH environments. Its natural origin makes it suitable for eco-friendly and sustainable manufacturing processes.
