CI 50420

Description

CI 50420, also known as Carbon Black, is a synthetic pigment widely used in cosmetic and skincare formulations. This ultrafine, deep black powder is composed of nearly pure elemental carbon produced through the controlled combustion or thermal decomposition of hydrocarbons. In skincare and cosmetic applications, CI 50420 serves primarily as a colorant, imparting an intense black hue to products such as eyeliners, mascaras, and eyeshadows.

The particle size of CI 50420 typically ranges from 10 to 30 nanometers, allowing for smooth application and even distribution in formulations. Its inert nature makes it compatible with a wide range of cosmetic ingredients. However, due to concerns about potential nanoparticle penetration, its use is generally restricted to rinse-off products or those intended for application around the eyes.

While CI 50420 is considered safe for cosmetic use by regulatory bodies when used as directed, ongoing research examines its long-term effects and potential environmental impact. Formulators must adhere to concentration limits and usage guidelines set by regulatory authorities. When incorporating CI 50420 into products, careful consideration must be given to particle size, dispersion methods, and overall formula stability to ensure optimal performance and safety.
