Basic Yellow 57 (also documented as C.I. 12719, CAS Number 73049-73-7) is a high-affinity cationic azo dye widely recognized for its vibrant golden-yellow hue. Unlike traditional anionic acid dyes, Basic Yellow 57 possesses a net positive charge. This structural feature governs its primary mode of action: electrostatically binding to negatively charged substrates, particularly the keratin proteins present in human hair, wool, silk, and acrylic fibers containing acid-modified group components.
In global cosmetic chemistry, Basic Yellow 57 has emerged as an industry-standard ingredient for semi-permanent hair colorants, color-depositing shampoos, and conditioning hair masks. Because of its cationic nature, it does not penetrate deep into the hair cortex like oxidative dyes; instead, it binds selectively to the outer cuticular structure. This provides long-lasting, vibrant color that washes out gradually without compromising the structural integrity of the hair shaft.
As a leading China Basic Yellow 57 Manufacturer & Supplier, Tianjin Sunrise Chem Group delivers precise control over molecular purity, heavy metals, and residual free amine concentrations, aligning with stringent European (SCCS) and American FDA cosmetic regulatory limits.
China's manufacturing sector remains the global cornerstone for dyes synthesis. Discover how our facility optimizes production to achieve the perfect balance between raw quality, economic scaling, and environmental stewardship.
By establishing strategic upstream alliances for critical intermediates—such as 3-aminobenzotrifluoride derivatives and diazo coupling components—our production lines avoid supply chain disruptions. This translates to constant batch availability and immune pricing indexes even during global material shocks.
We leverage High-Performance Liquid Chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS) to guarantee zero detectable free primary aromatic amines (PAA). Our refined purification process separates salt residues and trace reaction byproducts to ensure ultimate cosmetic safety.
Our facility operates under rigorous environmental control protocols. Equipped with modern biological aeration basins, catalytic oxidation, and nanofiltration water recycling networks, we satisfy the strictest local EPA limits, ensuring long-term manufacturing license viability.
In modern chemical procurement, credentials speak louder than promises. Sunrise Chem Group ensures that every batch shipped conforms to international eco-toxicological guidelines.
Our commitment is verified by leading third-party frameworks. The achievement of ZDHC Level 3 (Zero Discharge of Hazardous Chemicals) certification means our entire manufacturing process has been audited for compliance, systematically eliminating hazardous substances down to the supply line roots. In addition, our GOTS (Global Organic Textile Standard) verification assures that we supply safe input materials for organic fiber processing.
Furthermore, our testing procedures include checking color fastness, lightfastness, and compatibility with cationic surfactants to guarantee a seamless formulation experience for our customers.
Understanding how Basic Yellow 57 behaves in chemical systems allows us to tailor products for specific manufacturing sectors. Here is how our clients utilize our dye solutions globally.
In semi-permanent formulation, Basic Yellow 57 is blended with other basic dyes (such as Basic Brown 17, Basic Blue 99, and Basic Red 76) to construct a full spectrum of natural tones (from deep black to rich blonde). Because cationic dyes are highly sensitive to anionic surfactants, formulators pair Basic Yellow 57 with cationic emulsifiers (like Behentrimonium Chloride) and non-ionic surfactants to build stable, non-separating color creams and hair masks.
For specialized industrial applications, including the coloration of polyacrylonitrile (acrylic) fibers, Basic Yellow 57 provides exceptional brilliant tone buildup. Acrylic fibers contain acidic functional groups (sulfonic or carboxylic residues) introduced during copolymerization, which function as dye sites for our cationic compound. Additionally, in premium specialty paper mills, it is used for deep saturation dyeing where high water-fastness is required.
For large-scale users, chemical safety regulations (such as REACH and US EPA TSCA) demand detailed environmental accounting of dyes and effluents. Tianjin Sunrise Chem Group offers a macro-level partnership where we optimize dye particle sizes for easier wastewater flocculation.
Our dyes are formulated to ensure high exhaustion rates, meaning more dye molecules fix to the substrate and fewer are washed into the wastewater stream. This reduces chemical oxygen demand (COD) and biological oxygen demand (BOD) load in municipal biological water treatment plants.
The global colorant industry is experiencing a massive shift driven by safety, sustainability, and transparency. Key dynamics shape the demand for Basic Yellow 57:
