HC YELLOW NO. 2

Description

HC Yellow No. 2 is a synthetic dye widely used in the hair coloring industry, particularly for semi-permanent and temporary hair dyes. This water-soluble compound is known for its ability to impart vibrant yellow to golden hues to hair without the need for an oxidizing agent. Its chemical structure allows for effective penetration into the hair shaft, resulting in longer-lasting color compared to some other temporary dyes.

The ingredient is often combined with other hair dyes to create a range of shades, from warm blondes to rich browns. HC Yellow No. 2 is appreciated for its color stability and resistance to fading, especially when exposed to sunlight or frequent washing. However, it's important to note that this dye may cause allergic reactions in some individuals, necessitating patch tests before use.

In formulations, HC Yellow No. 2 is typically used at concentrations between 0.1% to 1%, depending on the desired intensity of the color. While effective for hair coloring, it is not approved for use around the eye area or in products that may come into contact with mucous membranes. Proper formulation and usage guidelines must be followed to ensure safety and optimal results.
