从India供应商批发进口Acid Orange 7 — FOB条款

Sparrowings International supplies Acid Orange 7, a synthetic acid dye identified by the CAS number 633-96-5 and EINECS number 211-199-0. This orange powder, with the molecular formula C16H11N2NaO4S, is sourced from Gujarat, India, and is primarily used in food, leather, and textile dyeing applications. Its water-soluble nature and vibrant hue make it a versatile choice for manufacturers requiring consistent coloration in aqueous-based processes.

As an acid dye, Acid Orange 7 from Sparrowings International is particularly effective for protein-based fibers like wool and silk, as well as leather, where it bonds ionically under acidic conditions. The dye’s molecular structure ensures high tinctorial strength, meaning lower concentrations can achieve intense shades. Standard industry practice involves dyeing at elevated temperatures (90-100°C) with controlled pH levels (3-5) to maximize fixation and color yield.

The product is marketed under the brand name Sparrowings and is supplied as a fine orange powder, suitable for both small-scale and bulk industrial use. Textile mills use it for vibrant orange shades in fabrics, while food manufacturers may employ it in products like confectionery, subject to regional regulatory approvals. Buyers should confirm the dye’s suitability for their specific application, including substrate compatibility and compliance with local food or textile regulations.

Sparrowings International is based in Ahmedabad, Gujarat, India, with its office located at D-101, Maruti Homes, Opposite Shreenath Elegance, Nana Chiloda.
