For companies involved in manufacturing goods where whiteness and brightness are key quality indicators, sourcing effective optical brighteners is a critical operational requirement. Optical Brightener Agent SWN, also known as OBA 140 or MDAC, is a widely recognized and utilized fluorescent whitening agent that offers significant benefits across industries. This article is designed to provide valuable insights for both buyers seeking to procure this chemical and manufacturers looking to understand its market position and demand.

Optical Brightener Agent SWN is celebrated for its high purity, typically 99.50%, and its characteristic crystalline powder appearance. Its primary function is to enhance the whiteness and brightness of various substrates by absorbing UV light and emitting visible blue-violet light. This optical effect counteracts yellowness, making materials appear cleaner and more visually appealing. Key applications include the textile industry for wool, silk, acetate, and acrylic fibers, where it provides a vibrant, luminous white. In the plastics sector, particularly for PVC, it improves clarity and whiteness. Furthermore, its inclusion in laundry detergents is a testament to its effectiveness in maintaining fabric brightness.

For buyers, understanding the technical specifications and application benefits of Optical Brightener Agent SWN is the first step in making an informed purchase. Its solubility in organic solvents and acidic solutions, coupled with its insolubility in water, dictates its optimal use in specific formulation processes. When looking to buy, it is essential to consider the source. Partnering with a manufacturer directly, especially one based in China, can offer significant advantages. These often include more competitive pricing due to economies of scale and direct manufacturing, as well as greater assurance of product quality and consistency.
