In the highly competitive landscape of global chemical synthesis, the selection of reliable partners for industrial colorants is a critical driver of supply chain resilience and product quality. Carmoisine Red, systematically designated as Acid Red 14 (C.I. 14720), is an anionic monoazo dyestuff recognized for its intense dark red to magenta profile, remarkable water solubility, and affinity for proteinaceous fibers and polar substrates. When sourcing Carmoisine Red, purchasing directors and chemical engineers look beyond mere color profile; they analyze chemical consistency, molecular purity, eco-compliance, and cost efficiency.
As a leading discount Carmoisine Red manufacturer and factory, Tianjin Sunrise Chem Group leverages advanced manufacturing protocols to deliver high-affinity Acid Red 14 that meets stringent international regulations. Whether applied in premium wool and silk dyeing, complex leather finishing, custom paper coloring, or eco-conscious chemical compounding, our factory-direct distribution model ensures that industrial bulk buyers secure premium materials without the inflated costs of intermediary brokers. This comprehensive whitepaper provides in-depth technical analysis, global commercial insights, sustainability frameworks, and future technical roadmaps for Acid Red 14 applications.

To fully understand the performance of Carmoisine Red, it is essential to explore its molecular makeup. Acid Red 14 is a sodium salt of 2-(4-sulfo-1-naphthylazo)-1-naphthol-4-sulfonic acid, with the chemical formula C20H12N2Na2O7S2 and a molecular weight of 502.43 g/mol. The molecule features a highly conjugated azo linkage (-N=N-) acting as the chromophore, flanked by naphthalene rings with sulfonic acid groups (SO3Na) that act as auxochromes. These auxochromes provide excellent water solubility and facilitate strong ionic bonding with cationic groups in protein fibers (such as the amino groups in wool, silk, and polyamide fibers).
Standard industrial grade Acid Red 14 must exhibit a dye content ranging from 85% to 99% depending on the application (textile versus high-purity cosmetic or specialty indicators). The pH stability range spans from 3.0 to 10.0, exhibiting color consistency across processing environments.
Acid Red 14 exhibits exceptional solubility in polar solvents: >70 g/L in water at 90°C and >25 g/L at 20°C. This prevents precipitation in concentrated dye baths, ensuring even dye distribution and avoiding spot defects on textiles.
It demonstrates lightfastness (Blue Wool Scale 4-5), wash fastness (ISO 105-C06 rating of 4), and perspiration fastness (rating of 4-5). This performance profile makes it suitable for fabrics exposed to regular washing and environmental elements.
The global market for Acid Red 14 continues to expand, driven by robust industrial growth in Asia-Pacific, Latin America, and select Eastern European territories. As traditional manufacturing hubs adjust to more stringent ecological standards, sourcing direct from reliable, modern factories has become essential.
In North America and the European Union, the focus is centered on eco-compliance and chemical traceability. Importers prioritize suppliers that provide comprehensive material safety data sheets (MSDS) and certificates of analysis (COA) verifying minimal heavy metal contents and the absence of restricted arylamines.
Conversely, in manufacturing-heavy corridors like India, Vietnam, and Bangladesh, the demand centers on economic viability, batch consistency, and reliable bulk delivery. Sourcing discount Acid Red 14 from a vertically integrated manufacturer like Tianjin Sunrise Chem Group bridges these market requirements by pairing cost efficiency with compliant production practices.
Through state-of-the-art automation and direct raw material sourcing, our Tianjin factory controls manufacturing costs while maintaining high quality. This helps our partners optimize margins in a competitive industrial landscape.
Tianjin Sunrise Chem Group specializes in manufacturing and exporting high-quality dyestuffs. Our comprehensive color portfolio includes Direct dyes, Acid dyes, Basic dyes, Sulphur dyes, Solvent dyes, Liquid dyes, and Fluorescent dyes. Backed by decades of industrial expertise and international trade experience, we have built a reputation for excellence, serving clients across diverse sectors including denim finishing, textile processing, leather tanning, papermaking, and plastics compounding.
Our operational philosophy is built on quality, consistency, and reliability. Every single shipment undergoes strict testing in our modern analytical labs prior to port delivery. This focus on consistency ensures that our products meet the exact specifications our customers expect.
No two manufacturing setups are identical. Recognizing this, our technical experts work closely with clients to formulate customized colorants that align with specific processing temperatures, substrate variations, and chemical environments. We actively seek strategic partnerships with global distributors, multinational chemical brands, and large-scale industrial mills.
By working with us, you gain access to a dedicated R&D team focused on improving color yields, reducing processing times, and lowering application costs. This collaborative approach drives mutual growth and keeps our partners competitive.
Cooperating with textile and paper mills for many years shows that the factory has established a strong and reliable business relationship. This kind of long-term collaboration brings numerous benefits, such as consistent orders, shared resources, and mutual support. It also indicates that the factory has a good track record of delivering quality products and meeting the needs of its partners. Our mission is to drive business growth by providing reliable and customized products.
Our goal is to make a significant contribution to our customers' success by consistently delivering first-class products and exceptional customer service. By building lasting partnerships, we strive to be a catalyst for our clients' success.

Tianjin Sunrise Chem Group meets stringent environmental frameworks, including ZDHC (Zero Discharge of Hazardous Chemicals) Level 3 and GOTS (Global Organic Textile Standard) certifications. These standards support clean textile processing and verify that our products are formulated with environmental safety in mind.
The ZDHC program brings brands, retailers, and suppliers together to reduce hazardous chemicals in the global supply chain. Achieving ZDHC Level 3 status shows that our chemical formulations are systematically evaluated and meet strict guidelines for chemical handling, wastewater treatment, and pollution prevention.
The Global Organic Textile Standard (GOTS) ensures the organic status of textiles from raw material sourcing through environmentally and socially responsible processing. Our certified products help mills target premium organic markets and ensure compliance with strict environmental criteria.
The versatility of Carmoisine Red spans several major industrial manufacturing sectors:
In wool and silk processing, Acid Red 14 is applied under acidic conditions (pH 4.5–5.5 adjusted via ammonium sulfate or acetic acid). This controls the dye uptake rate, ensuring level dyeing across the fabric. Elevating temperatures to 95–98°C helps maximize exhaustion rates and optimize color yield.
For chrome-tanned and vegetable-tanned leathers, Acid Red 14 provides uniform surface penetration. Sourced directly from our factory, the dye offers reliable coverage, hiding grain defects and delivering a deep, consistent red base.
In pulping processes, Carmoisine Red is added directly to the beater to color paperboard and specialty packaging. Its high solubility ensures clean dispersion, preventing color mottling and improving wet-strength characteristics in finished paper products.
In addition to Carmoisine Red (Acid Red 14), our factory produces a versatile range of dyes to support different printing and coloring applications globally.
The synthetic dyestuff industry is undergoing a significant transition. R&D initiatives are focused on reducing chemical footprints and optimizing the resources required during dye application.
At Tianjin Sunrise Chem Group, our future development centers on three main areas:
By addressing these targets, we aim to help our partners meet both their production goals and evolving environmental regulations.
