Tinopal（Cat No.:I037316）refers to a group of optical brighteners, also known as fluorescent whitening agents, which are used to enhance the appearance of materials by making them appear brighter. These compounds absorb ultraviolet light and re-emit it as blue light, counteracting yellowish or dull tones in fabrics, papers, and plastics. Tinopal is widely used in laundry detergents, textiles, and other consumer goods to improve the visual aesthetics of materials. While it is generally safe, some individuals may be sensitive to these chemicals. Tinopal is also studied for its role in various industrial applications requiring enhanced whiteness and brightness.
