Pearlescent pigments are widely used in decorative coatings to achieve a luxurious, shimmering finish that mimics the natural luster of pearls.

Pearl pigments, also known as mica-based pigments, are widely used to add a shimmering, metallic, or pearlescent effect to a variety of products, including paints, plastics, cosmetics, and coatings.

Both optical brighteners and titanium dioxide are physical whitening agents, and they do not react with other raw materials, while bleaching agents achieve whitening through chemical reactions.

The resulting colorant products containing Optical Brighteners or pigments with a relatively high concentration can be used directly and have become a major means of coloring plastics.
