CI 74100

Description

CI 74100, also known as Pigment Blue 15, is a synthetic inorganic pigment widely used in cosmetics and personal care products. This ultramarine blue colorant is prized for its vibrant hue and excellent stability across a range of pH levels. It belongs to the family of complex sodium alumino-silicate compounds and is characterized by its deep blue color with a slight reddish undertone.

In skincare and cosmetic formulations, CI 74100 serves primarily as a colorant, providing intense blue shades to various products such as eyeshadows, eyeliners, and other decorative cosmetics. Its insoluble nature makes it particularly suitable for powder-based formulations, where it maintains color consistency and resists bleeding or migration.

This pigment demonstrates good light fastness, meaning it retains its color when exposed to light over time. It is also heat-stable, allowing for use in products that may undergo thermal processing during manufacturing. CI 74100 is generally considered safe for use in cosmetics, with regulations permitting its use in all types of cosmetic products in most jurisdictions, including eye area applications. However, as with all colorants, it should be used at concentrations deemed safe by regulatory bodies.
