CI 73915

Description

CI 73915, also known as D&C Blue No. 6 or Indigo Carmine, is a synthetic blue dye commonly used in cosmetic and personal care products. This water-soluble colorant belongs to the indigoid family and is derived from coal tar. Its primary function is to impart a vibrant blue hue to various skincare, makeup, and hair care formulations.

In cosmetics, CI 73915 is frequently incorporated into eye shadows, eyeliners, and mascaras to achieve deep blue shades. It's also utilized in hair dyes and temporary hair color products. The dye's stability in different pH environments makes it versatile for use in a wide range of formulations.

While generally considered safe for topical use, CI 73915 may cause allergic reactions or skin irritation in some individuals, particularly those with sensitive skin. It's important to note that this colorant is not approved for use in products applied near the eye area in some countries due to potential safety concerns.

When formulating with CI 73915, care must be taken to ensure proper concentration levels and compatibility with other ingredients. Its intense pigmentation allows for effective coloration at relatively low concentrations, typically ranging from 0.001% to 0.1% in finished products.
