Buy & Import Acid Yellow 73 from Sparrowings International - India Wholesale Supply

Acid Yellow 73, supplied by Sparrowings International, is a fluorescent acid dye with the CAS number 518-47-8 and the molecular formula C20H10Na2O5. Also known as Fluorescein GDC, this dye is produced in Gujarat, India, and is primarily used in textile dyestuffs, cosmetics, and medicine. Its powder form and bright fluorescent yellow shade make it a popular choice for applications requiring high visibility or vibrant coloration.

As an acid dye, Acid Yellow 73 is characterized by its high solubility in water and strong affinity for protein-based fibers such as wool and silk. The dye typically exhibits a pH range of 3 to 5 for optimal absorption, with a standard color strength of 100 ± 5% (1/1 SD). Its fluorescent properties are a result of its xanthene structure, which allows it to absorb and emit light in the visible spectrum, making it ideal for applications where brightness is a key requirement.

Textile manufacturers, cosmetic producers, and pharmaceutical companies source Acid Yellow 73 for its ability to deliver intense, long-lasting color. The dye is often used in specialty fabrics, high-visibility textiles, and as a coloring agent in certain medicinal and cosmetic formulations. Sparrowings International offers this product under its own brand name, ensuring traceability and consistency for industrial buyers.

Frequently Asked Questions About Acid Yellow 73 from Sparrowings International
Acid Yellow 73 contains a xanthene structure, which is responsible for its strong fluorescence under UV light. This property makes it ideal for applications requiring high visibility, such as safety textiles, fluorescent markers, and certain cosmetic products where brightness is a key selling point.

Sourcing Acid Yellow 73 from Sparrowings International - India Import Guide

Before placing an order for Acid Yellow 73 from Sparrowings International, verify the dye’s purity and fluorescence intensity through a certificate of analysis and lab testing. Request a sample to evaluate color consistency and compatibility with your substrates, particularly if the dye will be used in high-visibility or specialty applications. Confirm that the supplier can provide batch-specific documentation to ensure reproducibility in your production runs.

For logistics, discuss packaging options that protect the dye from moisture and light, as fluorescent dyes can degrade under exposure to UV or humid conditions. Acid Yellow 73 is typically shipped in sealed bags or drums, so ensure your facility can handle these formats. Agree on Incoterms such as FOB Ahmedabad or CIF to your destination port, and clarify lead times, which may vary based on production and shipping schedules. Payment terms like TT or LC should be negotiated in advance to align with your procurement policies.

Conduct quality checks upon delivery, including visual inspection for color uniformity and testing for solubility and fluorescence under UV light. For textile applications, perform a dye trial to confirm the shade and fastness properties meet your requirements. Request comprehensive documentation, including the MSDS, COA, and any relevant test reports for light fastness and color strength. For cosmetic or medicinal use, ensure the dye complies with industry-specific regulations and standards.
