About HC BLUE NO. 11
A synthetic hair dye ingredient used to create color, with a higher chance of irritation or allergy than standard skincare ingredients.
Detailed Analysis
HC BLUE NO. 11 is a hair dye ingredient used to deposit or develop color in hair fibers. Hair dye materials are more tightly regulated than ordinary skin conditioners because they are more likely to cause eye irritation, scalp irritation, or allergic contact dermatitis, and Annex III restrictions in the EU limit how and where many of them can be used. This ingredient should be treated as a higher-caution cosmetic raw material.
