CI 77267

Description

CI 77267, also known as Black 2 or carbon black, is a widely used colorant in cosmetic and skincare formulations. This synthetic pigment is derived from the incomplete combustion of hydrocarbons, resulting in a fine, deep black powder. Its primary function is to impart intense black color to various products, including eyeliners, mascaras, and eyeshadows.

Carbon black possesses excellent light-absorbing properties, making it effective in UV-protective formulations. It exhibits high stability and resistance to pH changes, heat, and light, ensuring long-lasting color in cosmetic applications. The particle size of CI 77267 typically ranges from 10 to 30 nanometers, allowing for smooth application and even distribution in products.

While generally considered safe for use in cosmetics, some concerns exist regarding potential contamination with polycyclic aromatic hydrocarbons (PAHs). Regulatory bodies, including the EU and FDA, have established purity criteria and usage limits to address these concerns. It's important to note that CI 77267 is not approved for use in lipsticks or other products applied to the mucous membranes. When formulating with this ingredient, careful consideration of its concentration and intended use is essential to ensure product safety and compliance with regulatory standards.
