Acid Carmoisine, chemically known as **Acid Red 14** (CAS No. 3567-69-9), is an anionic azo dye characterized by its deep red to violet hue. Its molecular structure contains sulfonate groups ($SO_3Na$) which confer high water solubility, making it ideal for application in aqueous solutions. From an analytical perspective, the compound presents a molecular formula of $C_{20}H_{12}N_2Na_2O_7S_2$ and a molecular weight of 502.44 g/mol.
As a leading OEM supplier, Tianjin Sunrise Chem Group ensures that our manufactured Acid Carmoisine meets high chemical purity metrics. The raw dyestuff is standardized to avoid heavy-metal contamination, volatile organic compounds (VOCs), and banned aromatic amines. In the textile and leather sectors, the coloristic performance is heavily determined by dye-fiber affinities, controlled pH conditions, and dye concentration curves.
The global demand for Acid Carmoisine is driven by three main industries: textiles, leather tanning, and specialty industrial coloring (including wood coatings and ink manufacturing). Due to its brilliant red hue and outstanding leveling properties on polyamide, silk, and wool fibers, it remains a cost-effective alternative to more complex reactive dyes.
Key economic factors influencing the procurement of Acid Carmoisine globally include raw material cost fluctuations (specifically naphthalene derivatives and sulfonic acids), international environmental regulations, and energy costs. Western European and North American buyers prioritize suppliers with **GOTS** and **ZDHC Level 3** certifications, ensuring that their manufacturing supply chains comply with zero-discharge limits. Emerging economies in Asia-Pacific and South America remain the fastest-growing consumption markets, demanding stable, high-volume OEM contracts.
Standard industrial grade Acid Red 14 is often cut with sodium chloride or sodium sulfate to reach standard color strength (100%). However, for specialized membrane filtration or high-end ink applications, Tianjin Sunrise Chem Group offers custom-purified, salt-free configurations. This minimizes nozzle clogging in industrial printing and maximizes ionic bonding in leather matrices.
The manufacturing technology roadmap of Tianjin Sunrise Chem Group focuses on automating synthesis loops to minimize human error and ensure chemical homogeneity. Our next-generation R&D efforts target zero-wastewater discharge processes through continuous crystallization and nanofiltration. By recovering residual sodium salts from the synthesis effluent, we lower the overall carbon footprint of our Acid Carmoisine production by 22% compared to traditional batch methods.

We operate under a strict ecological framework, aligning our synthesis routes with leading international safety regulations to guarantee compliant exports.
The ZDHC Program: The ZDHC 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): The GOTS certification ensures the organic status of textiles from the harvesting of raw materials to environmentally and socially responsible manufacturing. It guarantees that the textiles are made from organic fibers, chemical inputs are minimized, and strict environmental and labor standards are met throughout the production process. GOTS certified products are considered sustainable, safe, and ethical. Both certifications are important in the context of sustainable and responsible textile production. ZDHC focuses on the elimination of hazardous chemicals, while GOTS certification guarantees the organic and ethical aspects of textile production.

Detailed industrial guidance from our laboratory team addressing composition, application protocols, and safety norms.
Although both are anionic azo dyes, Acid Carmoisine (Acid Red 14) is a disazo dye, while Acid Red 18 is a tri-sodium salt azo dye. Chemically, Acid Red 18 shows a slightly more yellowish-red tint, whereas Acid Carmoisine yields a deeper, more bluish-red to crimson tone. Their chemical structures differ in their sulfonic acid group counts, which directly influences water-solubility thresholds and fiber affinity kinetics.
ZDHC Level 3 is the highest chemical management compliance level in the Zero Discharge of Hazardous Chemicals guidelines. Buying ZDHC Level 3 certified Acid Carmoisine ensures that the manufacturing process does not use banned priority hazardous chemicals. This prevents supply chain disruptions, avoids batch rejections at customs, and ensures compliance with major consumer brands' restricted substances lists (RSLs).
For wool and nylon fibers, dyeing is typically initiated at 40°C, and then raised slowly to 95°C to 100°C over 45 minutes, maintaining a bath pH of 4.5–5.5 using acetic acid or ammonium sulfate. The acidic environment protonates amino groups on the fibers, generating cationic sites that ionically attract the anionic sulfonate groups of the Acid Carmoisine molecule.
Every OEM order is subjected to double testing. Our analytical lab tests the crude compound via High-Performance Liquid Chromatography (HPLC) and spectrophotometric color matching. A retains sample from each batch is stored in our system for up to two years, allowing quick retroactive verification if any technical performance deviations are reported by the customer.
