Optical Whitener Agent FB-401

Whitening agents are essential additives in the laundry industry. These compounds are used to enhance the appearance of fabrics, making them appear whiter and brighter. By absorbing UV rays and re-emitting it as visible blue light, whitening agents counteract yellowing and dullness in fabrics, ensuring clothes retain a fresh, bright appearance even after multiple washes.
