PIGMENT YELLOW 13

Description

Pigment Yellow 13, also known as C.I. 21100, is a synthetic organic pigment widely used in cosmetic and personal care formulations, particularly in haircare products. This bright, lemon-yellow colorant belongs to the diarylide yellow family and is prized for its excellent lightfastness and stability. Chemically, it is composed of benzidine coupled with acetoacetanilide, resulting in a vibrant, long-lasting hue.

In haircare applications, Pigment Yellow 13 is utilized in temporary hair coloring products, including sprays, gels, and mousses. It provides a vivid yellow tint without penetrating the hair shaft, making it suitable for short-term color experimentation. The pigment's particle size allows for even distribution and adherence to the hair surface, ensuring uniform color application.

This colorant exhibits good resistance to heat and pH variations, maintaining its integrity during styling processes. It is generally considered safe for cosmetic use when formulated properly and used as directed. However, as with any colorant, patch testing is recommended to check for potential allergic reactions or sensitivities. Formulators should be aware of regulatory guidelines regarding its concentration in finished products to ensure compliance with regional cosmetic standards.
