CI 11920

Description

CI 11920, also known as Red 36 or Pigment Red 4, is a synthetic organic pigment widely used in the cosmetics and personal care industry. This bright red colorant belongs to the monoazo class of dyes and is characterized by its vibrant hue and excellent color stability. CI 11920 is primarily utilized in lip products, such as lipsticks and lip glosses, due to its intense color payoff and ability to create rich, long-lasting shades.

The pigment demonstrates good dispersibility in various cosmetic formulations, including oil-based and anhydrous systems. It exhibits resistance to light and heat, ensuring color consistency over time. CI 11920 is not considered a lake pigment, which means it does not require aluminum substrates for color development.

While CI 11920 is approved for use in cosmetics in many countries, including the European Union and Japan, it is not FDA-approved for use in products intended for the lip area in the United States. Formulators must be aware of regional regulations when incorporating this ingredient. When used within approved concentrations and applications, CI 11920 is generally regarded as safe for topical use in cosmetic products.
