Uses:
Acid Red 18 (酸性红18) is a synthetic azo dye with the CAS number 2611-82-7. It is also widely known by its common names such as Ponceau 4R, Cochineal Red A, and in China, it is frequently referred to as 胭脂红 (Yānzhīhóng).
Here is a breakdown of its uses and key selling points:
Uses of Acid Red 18
Acid Red 18 is highly versatile and is used across several major industries due to its strong coloring properties:
Textile & Leather Industry: It is primarily used for dyeing protein fibers like wool, silk, and nylon, as well as their blends. Additionally, it is applied in the coloring of leather products.
Food & Beverage (Food Additive): In the food industry, it serves as a red food coloring (often labeled as E124 in Europe or Food Red 7 in China). It is commonly found in beverages, candies, cake decorations, jams, ice cream, and preserved fruits to provide a vibrant strawberry-red hue. (Note: Its use in food is strictly regulated and banned in some countries like the USA and Norway).
Cosmetics & Personal Care: It acts as a colorant in various cosmetic products, including hair dyes (both oxidative and non-oxidative), soaps, and daily chemical products.
Other Industrial Applications: It is used to color paper, ink, wood, plastics, and even in pharmaceutical formulations.
Selling Points & Advantages
The market demand for Acid Red 18 is driven by several distinct advantages:
Vibrant Color & Strong Tinting Strength: It produces a bright, uniform strawberry-red color with excellent tinting power, meaning a small amount goes a long way in achieving the desired shade.
Cost-Effectiveness: Compared to many natural dyes or other high-end synthetic alternatives, Acid Red 18 is relatively inexpensive to produce, offering a significant cost advantage for mass-market applications.
Good Stability: The dye exhibits good stability against light and acids (such as citric acid and tartaric acid), ensuring that colored products maintain their appearance over time without fading easily under normal conditions.
Water Solubility: As an acid dye, it dissolves readily in water, which makes it easy to apply evenly during industrial dyeing and manufacturing processes.
If you are looking into this chemical for specific industrial purchasing or research purposes, always ensure compliance with your local safety regulations and environmental standards, as handling synthetic azo dyes requires proper safety precautions.
