Is it true that mascara pigment must be inert or unable to combine with other elements?

1. True

2. False

3. Only in specific formulations

4. Depends on the manufacturer

The correct answer is: True

Mascara pigment must indeed be inert or unable to combine with other elements to ensure safety and effectiveness in cosmetic formulations. Inert pigments do not react chemically with other ingredients, which helps prevent the formation of harmful compounds or adverse reactions when the product is applied to the sensitive eye area. This requirement is critical for maintaining the stability of the mascara formula, ensuring that the product remains safe for wear, and providing consistent color without the risk of contamination or negative interactions. In addition, an inert pigment contributes to the longevity and durability of the product on the lashes, making it both functional and reliable for consumers.
