Colorant Test


Colorants are commonly used in cosmetics to give them different colors or change the color of the skin or hair. Colorants can be found in almost all cosmetic products such as lipstick, eye shadow, nail polish, blush, mascara, and even sunscreen.

Since these colorants touch human skin, they must go through strict safety and stability tests to ensure they're safe and won't change over time. Some people might also have allergies to certain colorants. Therefore, it is important to identify the ingredients of colorants in cosmetics.

Regulations on the Use of Colorants

Organizations such as the FDA and the WTO have strict rules about the use of color additives in cosmetics to keep consumers safe. Depending on where they'll be used on the body, colorants are divided into four categories.

  1. Safe for all cosmetics.
  2. Safe for all cosmetics except those near the eyes.
  3. Safe for cosmetics that briefly touch the skin.
  4. Safe for cosmetics that don't touch mucous membranes.
