BASIC BLUE 124

Description

Basic Blue 124, also known as Acid Blue 124 or CI 44090, is a synthetic colorant commonly used in haircare formulations. This water-soluble dye belongs to the triphenylmethane class of compounds and is characterized by its vibrant blue hue. Basic Blue 124 is particularly effective in temporary hair coloring products, shampoos, and conditioners designed for cool-toned or silver hair.

The ingredient's molecular structure allows it to adhere to hair fibers without penetrating the cortex, resulting in a non-permanent coloring effect. This property makes it ideal for color-depositing treatments and toning products. Basic Blue 124 is often used in conjunction with other dyes to create various shades and neutralize unwanted yellow or brassy tones in lightened or gray hair.

While generally considered safe for cosmetic use, Basic Blue 124 may cause skin or scalp irritation in sensitive individuals. It is important to note that this colorant is not approved for use in the eye area or in products that may come into contact with mucous membranes. Formulators should be aware of regulatory guidelines and concentration limits when incorporating Basic Blue 124 into haircare products.
