Aka227
What is Aka227?
Aka227, known as Red No. 227 in Japanese cosmetic standards, is a synthetic monoazo lake pigment derived from azo compounds, typically in the form of calcium, barium, or aluminum salts of CI 15850:1. This water-insoluble pigment provides intense, bright red coloration by selectively absorbing certain light wavelengths and reflecting red light. It is commonly incorporated into color cosmetics like lipsticks, blushes, eyeshadows, and nail polishes, where it disperses evenly in oily or anhydrous bases to ensure consistent pigmentation, color stability, and resistance to migration or fading during use. Approved for cosmetic use by regulatory authorities in Japan, Aka227 helps manufacturers achieve uniform shades across product batches, enhancing visual appeal without compromising formulation integrity. Its lake structure minimizes solubility issues, making it suitable for long-wear applications on skin and nails.
