Overview
Orange AB is a synthetic azo dye widely recognized for its vibrant orange-red hue. It is primarily used in industries requiring stable and bright colorants, such as food, textiles, and cosmetics. The dye is known for its solubility in water and resistance to fading under normal conditions. Due to its synthetic nature, Orange AB is subject to regulatory scrutiny in various regions. Buyers should ensure compliance with local and international safety standards before procurement.
Physical and Chemical Properties
Orange AB appears as an orange to red powder with a molecular weight of 350.32 g/mol. It is highly soluble in water and slightly soluble in ethanol, making it versatile for aqueous applications. The dye exhibits stability under typical storage conditions but may degrade under prolonged exposure to light or moisture. The molecular formula of Orange AB is C16H11N2NaO4S, indicating its azo dye classification. This structure contributes to its bright color and stability, though it may pose health risks if mishandled.
Main Applications
Orange AB is predominantly used as a food coloring agent, particularly in products like candies, beverages, and processed foods. Its vibrant color and stability make it a popular choice for enhancing visual appeal. In the textile industry, Orange AB is employed for dyeing fabrics, offering excellent color fastness. The cosmetics industry also utilizes this dye in products such as lipsticks and eyeshadows, where bright, long-lasting colors are desired.
Safety and Storage
Orange AB should be stored in a cool, dry place, away from direct sunlight and moisture to prevent degradation. Proper ventilation is recommended to avoid dust accumulation, which can pose inhalation risks. Safety precautions include wearing protective gloves, goggles, and masks during handling. The dye should not be ingested or allowed to come into contact with skin or eyes. In case of exposure, rinse thoroughly with water and seek medical advice if necessary.
B2B Procurement Guide
When procuring Orange AB, buyers should prioritize suppliers with verified certifications and a track record of compliance with safety standards. Key factors to consider include purity levels, batch consistency, and packaging quality. Price negotiations should account for bulk purchase discounts, but quality should not be compromised. Request samples for testing before large-scale orders to ensure the product meets specific application requirements.
