Description

Basic Blue 99 is a synthetic cationic dye with a deep blue color, sits on or slightly penetrates the hair cuticle; it doesn't need developer and that’s why it’s widely used in hair coloring applications. It appears as a dark blue powder that is highly soluble in water, allowing it to provide vibrant, long-lasting color in semi-permanent hair dyes and other formulations.

Known for its stability and ease of use, Basic Blue 99 is effective even at low concentrations, making it a popular choice in cosmetics and industrial coloring processes. It is generally considered safe for topical use, though a patch test is recommended to check for potential skin sensitivity.
