3. How Does Optical Brightener OB Powder Work?

Curious about the science behind it? Optical brighteners work by absorbing ultraviolet light which is invisible to the human eye. When this light is absorbed, the optical brightener re-emits a different wavelength of light, typically in the blue spectrum. This blue light offsets the yellow tones in materials, making them appear whiter.
