ACID RED 73

Description

Acid Red 73, also known as Brilliant Cresyl Blue, is a synthetic dye used in various hair coloring products. This water-soluble compound belongs to the oxazine family of dyes and is characterized by its deep blue-violet hue. In haircare formulations, Acid Red 73 is primarily employed to impart vibrant, cool-toned shades to hair, ranging from deep purples to intense blues.

The dye's molecular structure allows it to penetrate the hair shaft effectively, providing long-lasting color results. Acid Red 73 performs optimally in acidic environments, making it suitable for use in semi-permanent and demi-permanent hair color formulations. Its ability to adhere to the hair cuticle without significantly altering the hair's internal structure contributes to its popularity in temporary coloring products.

When formulating with Acid Red 73, it is essential to consider its pH sensitivity and potential interactions with other ingredients. The dye's performance can be enhanced by combining it with other compatible colorants to achieve a broader spectrum of shades. However, as with all hair dyes, patch testing is recommended to assess potential allergic reactions or sensitivities in individual users.
