The beauty industry is known for its ever-evolving trends and innovative products, but one ingredient that has stood the test of time is pearlescent pigment. This mineral is prized for its shimmering properties and is used extensively in cosmetics such as eyeshadows, highlighters, and blushes. However, the increasing demand for mica in beauty products has raised significant concerns about its ethical sourcing and environmental impact. The mining practices associated with mica extraction, particularly in developing countries, have been linked to exploitative labor practices, including child labor and unsafe working conditions. As a result, the beauty industry is being called to ensure that the mica used in products is sourced ethically and sustainably. This article explores the importance of ethical sourcing of mica pigments, the challenges involved, and the efforts being made to promote sustainability in the beauty sector.

Natural mica powder and synthetic mica powder also have great differences in electrical insulation, mechanical properties, chemical stability, application range and cost. Natural mica powder has good electrical insulation, but the volume resistivity is lower than that of synthetic mica. Synthetic mica powder has better electrical insulation properties, high volume resistivity and stable dielectric constant, and is suitable for high performance electrical insulation materials. The hardness of natural mica powder is relatively low (2-3), and it has good elasticity and peeling property. The hardness of synthetic mica powder is higher (between 3 and 4), and the tensile strength and compressive strength are better than that of natural mica powder. Natural mica powder is stable in acid-base solution, but it is easy to decompose at high temperature. Synthetic mica powder is stable to acid and base at room temperature, but will be slowly corroded by sulfuric acid above 300℃. Better thermal stability, not easy to release gas. Natural mica powder is widely used in electrical appliances, welding rods, rubber, plastics, paper making, paint and other fields. Synthetic mica powder is mainly used in high-end electrical insulation materials, aviation, aerospace, national defense industry and other high-tech fields. Because synthetic mica powder needs to be produced through complex chemical processes, its production cost is usually higher than that of natural mica powder. Therefore, in the market, the price of synthetic mica powder is often higher than that of natural mica powder. However, with the continuous progress of production technology and the gradual emergence of scale effects, the price of synthetic mica powder is expected to gradually decrease.
