Black 2, also known as CI 77266 or Carbon Black, is a pigment commonly used in cosmetic formulations. It is produced through the incomplete combustion of certain oils and gases, resulting in a black powder which is then refined for use in a variety of applications.
In cosmetics, Black 2 is primarily used to provide color, especially in products like mascara, eyeliner, and eyeshadow. Its deep black color makes it perfect for these applications. It is also used in some hair dye formulations. The advantage of Black 2 is that it is highly stable, non-bleeding, and provides a strong, opaque black color.
However, its usage is regulated in many countries due to potential health concerns. The particle size of Black 2 needs to be controlled to prevent any respiratory issues if inhaled.
