Fluorescent Brightener 33, identified by CAS number 61902-19-0, is a highly regarded synthetic chemical compound belonging to the stilbene family. Its primary characteristic is its potent fluorescence, making it an indispensable tool for enhancing the whiteness and brightness of various materials. Understanding its core properties and a wide array of applications is crucial for industries that rely on visual appeal and material integrity.

The fundamental property of Fluorescent Brightener 33 is its ability to absorb ultraviolet (UV) radiation, typically in the range of 340-380 nm, and re-emit this energy as visible light, primarily in the blue region of the spectrum (around 430-440 nm). This phenomenon effectively compensates for the natural yellowing or dullness that can affect many substrates. By adding a 'blue' tint, it makes materials appear whiter and brighter to the human eye. With a high purity level of 99% min, its performance is reliable and consistent.

The applications of this optical brightener are extensive. In the plastics industry, it's a key additive for polymer whitening, ensuring products maintain a brilliant white appearance, crucial for consumer goods, packaging, and automotive parts. The textile industry widely uses it as a whitening agent for natural and synthetic fibers, improving fabric aesthetics. Furthermore, it's a common ingredient in laundry detergents and general whitening agents, boosting the visual cleanliness of garments.
