Ronastar^® Blue Lights – the new interference pigment for blue shimmer

• Addition to Ronastar^® Lights series of the Smart Effects program
• Small particle size with directed light reflection and high chroma thanks to engineered high-tech pigment architecture
• Blue living sparkle effect even in very low concentrations

Merck KGaA, Darmstadt, Germany, a leading science and technology company, today introduced Ronastar^® Blue Lights. The new premium pigment is another addition to the Lights series of the Smart Effects innovation program. The blue interference pigment creates a living sparkle effect even in very low concentrations. With its very fine particle size, it is ideal for modifying any shade and pastel nuances, adding a luxurious touch to all color and care cosmetics

Ronastar^® Blue Lights provides a unique edge for high value products. “With Blue Lights, color is not the limit. Perfectly fitting to latest color trends in decorative cosmetics, it adds gorgeous effects to temporary hair or care products,” says Beate Anniés, Head of Cosmetics at Merck KGaA, Darmstadt, Germany. “In care products, the hovering marbles of indigo sparkle can help our customers underscore their marketing story like moisturization, marine active ingredients or clean beauty.”

“The engineered high-tech architecture of the Lights Series pigments is based on a combination of innovative substrate technology and precisely applied layers of metal oxides. The pigments thus feature uniform thickness and an extremely even surface,” adds Dorothea Wenzel, Head of Surface Solutions at the Performance Materials business sector of Merck KGaA, Darmstadt, Germany. “This inorganic composition provides highest stability combined with a smooth skin feel.”

Thanks to the very fine particle size, Ronastar^® Blue Lights make new synergistic sparkle effects possible when blended with pigments consisting of larger glitter particles. This makes it ideal for modifying any shade and creating pastel nuances.

Ronastar^® Blue Lights can be used in all color cosmetic and personal care applications. They complement the Ronastar^® portfolio consisting of the two mass tone pigments Ronastar^® Flaming Lights and Dazzling Lights as well as the two interference pigments Ronastar^® Golden Lights and Red Lights.
