The quest for pristine whiteness is a constant in many industries, from textiles and paper to plastics and detergents. Optical Brightener 31 (CAS: 12224-16-7), also known as Fluorescent Brightener 85 or C.I. 31, is a cornerstone chemical additive that achieves this by leveraging the fascinating principles of fluorescence. As a premier manufacturer and supplier, we are pleased to share insights into this vital product and its applications.

How Optical Brightener 31 Works: A Scientific Explanation

Optical brighteners operate on a simple yet ingenious principle: they absorb invisible ultraviolet (UV) light and re-emit it as visible light in the blue spectrum. This phenomenon is known as fluorescence. Many materials, due to their inherent chemical composition or age, tend to absorb blue light and reflect more yellow light, appearing dull or yellowish. Optical Brightener 31 combats this by absorbing UV radiation and converting it into blue light. This emitted blue light effectively cancels out the yellow hue, making the material appear whiter and brighter to the human eye. Unlike chemical bleaching agents that actually remove color molecules, optical brighteners enhance brightness by manipulating light.

Key Specifications and Properties

Optical Brightener 31 is typically supplied as a light yellow powder. Its chemical formula and structure contribute to its excellent fluorescent properties and stability. The key specifications often sought by manufacturers include its fluorescent strength, color shade, and purity. We ensure our product meets stringent quality standards, providing consistent performance for your applications. The CAS number 12224-16-7 is universally recognized for this specific fluorescent whitening agent, making it easy to source and specify.

Dominant Applications of Optical Brightener 31

The primary applications for Optical Brightener 31 are:

  • Textiles: It is widely used to whiten and brighten cellulose fibers, cotton, and synthetic fabrics like vinylon and nylon. It provides a brilliant white finish, essential for apparel and home textiles.
  • Paper: In the paper industry, Optical Brightener 31 enhances the brightness and whiteness of paper products, crucial for printing, writing, and packaging materials.
  • Other Applications: While less common, it can also find use in certain plastics, detergents, and inks where a bright white appearance is desired.
