What is the primary function of magnesium carbonate in cosmetics?

The primary function of magnesium carbonate in cosmetics is to contribute to the smoothness of the powder and absorb added perfume. This compound helps in creating a fine texture for powders, which ensures a smooth application on the skin. Its ability to absorb fragrance components is also essential in cosmetic formulations, particularly in powders and certain creams, enhancing the overall user experience by allowing the product to have a pleasant scent. This makes magnesium carbonate an important ingredient in the formulation of products aimed at providing a luxurious feel while ensuring that fragrances remain stable and effective. Other roles played in cosmetic formulations, such as increasing opacity, providing color, or enhancing lathering properties, do not align with the key characteristics and functions of magnesium carbonate.
