What it is

Basic Yellow 57 is a cationic (positively charged) synthetic dye from the basic dye family, often used in hair color formulations and rinse-off personal care products for its bright yellow shade.

How it works

In a cosmetic product, Basic Yellow 57 works by binding to negatively charged surfaces like hair or skin proteins, depositing color that can last through several washes. In rinse-off products, it simply tints the product itself for visual appeal without significant skin or hair staining.

Low cost

As a synthetic dye, it is inexpensive to produce, keeping the final product affordable for consumers.

Cons and cautions

Irritation potential

Some people may experience redness, itching, or stinging, especially on sensitive or damaged skin, because the dye can be mildly irritating.
