Coloring System Components This constitutes the core element that determines color rendition. Common ingredients include iron oxide pigments (such as black, red, and yellow iron oxides), as well as certain organic dyes or dye precursors. These components are responsible for delivering eyebrow shades of varying depths and intensities, while ensuring the color appears natural and remains true-to-tone without shifting.
Matrix and Film-Forming System
Primarily composed of solvents-such as water, propylene glycol, and glycerin-this system serves to dissolve or disperse the pigments. Additionally, film-forming agents or resinous ingredients (e.g., acrylate copolymers) are incorporated to create a uniform film over the eyebrows; this enhances adhesion and longevity, thereby preventing color fading or smudging.
Auxiliary Functional Ingredients:
These include thickening agents (such as Carbomer and Xanthan Gum), emulsifiers, preservatives, and pH regulators. These ingredients function to refine the product's texture, enhance its stability, inhibit microbial growth, and ensure that the product maintains consistent performance throughout its storage and usage lifecycle.
