FDA Expands Use of Pigment Mica Titanium Pearlescent Pigment

Pearlescent pigments refer to decorative pigments with pearl luster. Mica titanium pearlescent pigments are composed of mica as the matrix, and a layer of high refractive index TiO2 and other metal oxide transparent films are coated on the surface. It is widely used in cosmetics, food, paint, decoration and ink, ceramics and other industries. Its performance is good, non-toxic, good pearlescent, heat resistance, weather resistance and chemical resistance are good.

On April 23, 2015, the United States issued the G/SPS/N/USA/2754 notification, revising the regulations on the use of pigments, to allow mica titanium pearlescent pigments to be used as food additives in distilled alcohol. According to the latest regulations, when mica titanium pearlescent pigments are used in distilled spirits with an alcohol content between 18% and 25% (by volume), the maximum addition amount should not exceed 0.07% (by weight), for those containing more than 5% Distilled blends of wine are lifted from the current restrictions.

In June 2015, the U.S. Food and Drug Administration (FDA) revised the regulations on food pigments, expanded the use of pigment mica titanium pearlescent pigments, and proposed mica titanium pearlescent pigments prepared from titanium dioxide and mica for use in kabobs, spirits, flavors Safe use regulations in alcoholic malt beverages, wine coolers, cocktails, mocktail mixers and mixtures, egg coloring tools, and revisions to the list of food colorants exempted from FDA certificates, adding mica-titanium pearlescent pigments. The regulation came into effect on June 9, 2015.

The development history of mica-titanium pearlescent pigments is very short, but the prospects are very attractive. As a fine chemical product, mica-titanium pearlescent pigments have high added value. my country's natural mica and titanium resources are very rich, and it has the material basis for the development of mica-titanium pearlescent pigments. At present, the production technology of silver-white and rainbow-type pearlescent pigments in China is mature, but the research on the development of coloring and functional materials is not perfect.

In view of the various disadvantages of carbon-based, metal-based and metal oxide-based conductive pigments, the development of flake conductive composite functional materials based on mica or mica-titanium will be the focus of future research in the field of pearlescent pigments.

With the continuous improvement of people's requirements for the appearance quality of articles, the application field of mica-titanium pearlescent pigments is expanding, and higher requirements are placed on the chromatographic range of pearlescent pigments. Therefore, broadening the chromatographic range of colored pearlescent pigments is another research focus in the future.
