What do metal salts provide in cosmetic formulations?

Moisture
Texture improvement
Intense color
Stability

The correct answer is: Intense color

Metal salts are commonly used in cosmetic formulations primarily for their ability to provide intense color. They serve as pigments or colorants that can enhance the visual appeal of the cosmetic product. This is especially true in products like eye shadows, blushes, and other pigments where vibrant colors are desired. The reason why intense color is highlighted as a key benefit is due to the specific properties of metal salts that allow them to reflect and absorb light in ways that create bold hues. For instance, certain metal oxides are used extensively in the formulation of mineral makeup due to their ability to produce strong, vibrant colors that adhere well to the skin. While moisture, texture improvement, and stability are important aspects of cosmetic formulations, the primary function of metal salts is their role in contributing to the intensity and quality of color, making them essential for achieving desired aesthetic outcomes in various products.
