Explore our elite range of industrial colorants, pigments, and synthetic chemicals optimized for global trade, textiles, leather, and paper mills.
Malachite Green, scientifically designated as Basic Green 4, is a highly effective cationic triarylmethane dyestuff extensively utilized across complex industrial ecosystems. Globally recognized for its deep color saturation and powerful chemical affinity, this organic colorant plays a critical role in coloring polyacrylonitrile (acrylic) fibers, wool, silk, jute, and bamboo fibers. In addition, its superior structural properties make it a staple in high-precision paper manufacturing, leather dyeing, and advanced wood stains.
As a leading Chinese dyestuff authority, Tianjin Sunrise Chem Group bridges the gap between massive factory productivity and strict international regulatory compliance. Through advanced synthetic pathways, our chemical plant delivers crystalline and liquid formulations that feature exceptional purity, optimized dispersion, and minimized environmental footprint.

Industrial users require bulk-scale chemical shipments that remain uninterrupted by seasonal fluctuations. Sunrise Chem Group's manufacturing capacity guarantees constant availability of Basic Green 4 crystal and liquid variants, preventing line shutdowns for paper mills and textile dye houses.
Procuring raw materials from unverified sources increases the risk of trace heavy metal contamination (specifically zinc-based impurities). We offer high-purity Malachite Green Oxalate (Zinc-Free) specifically developed to satisfy strict ecological criteria in the EU and NA markets.
We supply Malachite Green in customizable configurations to match the specific operating requirements of automated chemical dosing systems: 25kg iron drums, reinforced multi-layer paper bags, or highly concentrated stable liquid solutions.
Deploying Basic Green 4 across global heavy industries demands specialized formulations. We address these challenges with custom chemical options.
In the paper industry, Malachite Green is valued for its direct affinity to lignin. For unbleached kraft pulp, mechanical wood pulp, and high-yield recycled fiber, our cationic dyes bind to the fibers without needing fixing agents. This yields vibrant greens, deep colors, and clean waste streams, reducing chemical usage.
In textile applications, Basic Green 4 is primarily used to color acrylic (polyacrylonitrile) fibers. Our formulation displays excellent light fastness and washing fastness on synthetic substrates. Additionally, when combined with mordants, it produces brilliant, deep shades on natural silk, wool, and cotton blended yarns.
For genuine leather and synthetic polyurethane (PU) materials, color consistency across batches is crucial. Our dyestuffs penetrate deep into the hide fiber matrix, resulting in even color distribution, high abrasion resistance, and excellent compatibility with finishing oils and resins.
Beyond traditional coloring applications, our high-purity Malachite Green variants are used as pH indicators (transitioning from yellow to green-blue in the pH range of 0.0 to 2.0), biological staining agents in microscopy, and in non-destructive structural inspection dyes.
