  • Applications

    Laccaic acid (CAS 60687-93-6) is a natural pigment extracted from lac insects and is used mainly as a red dye in textile processing, particularly for natural fibers such as silk, wool, and cotton, and for dyeing leather. It is also employed as a colorant in printing inks and decorative coatings (paints, varnishes). Additionally, laccaic acid may serve as an intermediate or color component in the production of synthetic dyes and related color compounds. Its use is subject to local regulations and formulation limits.
