According to the company, synthetic mica pigments have a number of formulation advantages over natural mica pigments, including: a brighter color, consistent color, controllable particle size, resistance to breakage, and versatile pigment options. Regarding brighter color, pearlescent pigments depend on reflected and refracted light to create unique and dramatic effects. Conversely, synthetic mica allows light to pass through, achieving brighter color, greater luster and accentuating the pearl effect. This is because synthetic mica pigments are laid out and classified by particle size, and the material is a single layer thick—less opaque than natural mica. Substrates built from these single layers therefore produce increased reflection and depth of field.

In addition, in relation to color consistency, while the color of natural mica ranges from slightly yellow  to brown or black and must be carefully evaluated for consistency, synthetic mica’s consistent white color ensures that the pearl pigment produced from a formula using it will be the same, consistent color.

Finally, since synthetic mica platelets are uniform, particle size can be controlled in applications and they reportedly perform the same way each time. According to the company, the platelets disperse easily in liquid, oil or gel; remain uniformly dispersed; are more resistant to breakage because synthetic mica flexes more easily than natural mica; and they can be used to create varying pigments and effects.

The pigment line is recommended for eye products, lipstick, facial makeup and nail polish, and reportedly meets all applicable US Food and Drug Administration, European Union and Japanese Health Ministry regulatory requirements.
