Premium grade dyestuffs engineered for maximum tinting strength, chemical stability, and environmental standard compliance.
Basic Green 4, also scientifically cataloged as Malachite Green (C.I. 42000), stands as one of the most prominent cationic (basic) dyes in modern industrial chemistry. Characterized by its brilliant green crystalline powder or dense liquid form, this triarylmethane dyestuff exhibits exceptional affinity for polyacrylonitrile (acrylic) fibers, paper pulps, leather substrates, and cellulosic materials when combined with appropriate mordants.
Industrially synthesized through the condensation of benzaldehyde and dimethylaniline followed by oxidation, Basic Green 4 yields high color intensity and notable brilliance. In global markets, OEM buyers evaluate Basic Green 4 based on its purity profiles, salt content, dustiness index, and solubility rates. Partnering with a specialized OEM manufacturer ensures that these critical physical-chemical properties are precisely calibrated to align with specific factory processing environments.
“The performance of C.I. Basic Green 4 is heavily dependent on batch consistency, trace impurity control, and customization of the physical state (crystalline vs. liquid) to match automatic dosing equipment.” — Tianjin Sunrise Chem Group R&D Division
The global demand for Basic Green 4 continues to grow, driven by sectors seeking vibrant color profiles that cannot be easily replicated by direct or acid dyes. In the Asia-Pacific region, the booming packaging sector relies on high-yield basic dyes to color kraft paper and corrugated cardboards. Simultaneously, in regions like South America and Southeast Asia, the textile and leather finishing markets leverage Basic Green 4 for deep-tone leveling.
In response to changing international trade policies and environmental regulations, the supply chain for industrial colorants has undergone significant integration. Buyers are transitioning away from small-scale traders to establish direct relationships with OEM factories capable of providing comprehensive quality guarantees. Direct factory sourcing minimizes risk, guarantees batch-to-batch consistency, and delivers significant cost efficiencies to high-volume buyers.
Paper and Pulp Coloring: Basic Green 4 is highly utilized in coloring structural packaging and decorative papers. Because of its strong affinity for lignin, it bonds directly to unbleached chemical pulps and mechanical wood pulps without the need for sizing agents, making the coloring process highly efficient.
Acrylic and Silk Dyeing: In the textile industry, Basic Green 4 provides rich, deep green tones on acrylic fibers through ionic bonding with acid groups. It exhibits excellent build-up properties and yields bright shades on silk and wool when applied with precise pH controls.
Wood Coating and Ink Production: As an alcohol-soluble colorant, it serves as a base for wood stains, marking inks, and specialty inks where immediate drying and bright coloration are required.
China remains the primary supplier of Basic Green 4, with Tianjin Sunrise Chem Group leading the market. The efficiency of Chinese manufacturing is built on three core pillars:

The ZDHC (Zero Discharge of Hazardous Chemicals) program is a collaborative effort by leading brands, retailers, and suppliers in the textile and footwear industry to reduce the use of hazardous chemicals. The focus of this certification is on eliminating the release of hazardous chemicals into the environment throughout the entire supply chain. Achieving ZDHC Level 3 certification indicates that our company has implemented robust chemical management procedures and has met the stringent requirements for chemical handling, wastewater treatment, and pollution prevention.
The Global Organic Textile Standard (GOTS) is a certification that ensures the organic status of textiles from the harvesting of raw materials to environmentally and socially responsible manufacturing. The GOTS certification guarantees that the textiles are made from organic fibers, that chemical inputs are minimized, and that strict environmental and labor standards are met throughout the production process. GOTS certified products are considered to be sustainable, safe, and ethical.

Key information regarding the chemical specifications, applications, and logistical requirements of Basic Green 4.
Basic Green 4 Crystal consists of highly concentrated dye structures with minimal water content, offering high coloration power per unit weight, which helps reduce transport costs. Basic Green 4 Liquid is a pre-dissolved formulation designed to eliminate dust in handling and to integrate smoothly with automatic dosing systems in modern paper and textile mills.
We use digital spectrophotometers (such as Datacolor systems) to test each batch for color values and strength profiles relative to master standards. Standardized production procedures ensure key parameters are kept within narrow thresholds (e.g., strength tolerance of ±2%, delta E < 0.8), ensuring consistent performance for our partners.
ZDHC Level 3 represents the highest level of assurance that a chemical manufacturer's products comply with the Manufacturing Restricted Substances List (MRSL). This ensures that no hazardous chemicals are used during the synthesis of Basic Green 4, helping buyers meet global eco-standards and avoid regulatory issues in key consumer markets.
For eco-certified garments, dyestuffs must meet standards like the Global Organic Textile Standard (GOTS). GOTS-certified variants of Basic Green 4 undergo strict testing for heavy metals and toxicity, helping manufacturers meet green textile criteria.
Basic Green 4 should be stored in a cool, dry, well-ventilated warehouse, away from direct sunlight, moisture, and strong oxidizing agents. Drums must remain sealed when not in use to prevent the dye powder from absorbing ambient humidity, which can lead to clumping.
Direct OEM sourcing from established manufacturers offers stable, formula-based pricing that protects buyers from spot market volatility. By coordinating production schedules directly with the factory, long-term partners secure reliable supply and consistent costs.
Standard OEM production runs for custom concentrations require 15 to 20 days from order confirmation to port delivery. This timeframe includes chemical synthesis, stabilization steps, color matching tests, and packaging.
