The artificial substrates are coated with high-refractive metal oxides, such as titanium dioxide or iron oxide, enabling optimum interference effects in combination with outstanding transparency. Its characteristics provide for new dimensions in eye-catching effects.
EMD’s Xirona Moonlight Sparks is another unique product that combines a sparkle effect with color that travels from metallic gold to subtle silver. A little goes a long way to make a high impact. Color-change and interactive pigments will increasingly have a role in the beauty market, according to LPK’s Morris. Such “gonichromatic” pigments can produce different colors depending on the incidence of light and the angle of observation, enabling manufacturers to create 3-D optical effects on the skin.
The special coating technology on the calcium aluminum borosilicate substrate provides a very clear and sparkling impression, and its high transparency helps it highlight cosmetic formulas without changing their base color. To top it off, Moonlight Sparks provides superior skin adhesion, according to the company. Cosmetic formulations with long-lasting claims will particularly benefit from the enduring silvery and golden sparkling effects.
EMD’s Timiron Ice Crystal is another such high-intensity pigment that delivers a sophisticated radiance—the “wow factor,” if you will—to any product formula, even in opaque applications, without compromising color or quality. Its larger particle size is engineered to provide feel characteristics that are not anticipated by its visual appearance. “It doesn’t give you that gritty feel you might expect,” said Vaiarelli. It combines with other pigments to achieve a wide range of colorful, vibrant effects. “We’re looking to combine Timiron with other pigments so you can really see this shine,” added Linz. Timiron Ice Crystal is based on synthetic fluorphlogopite which is coated with titanium dioxide.
“Fluorphlogopite will serve as a new generation of interference pigments,” said Linz. “I can’t speak to how, but it would make sense to make interference colors with this with new coating techniques.”
