HPC Today

• Multilayer technology produces an intense sparkle with exceptional hiding power
• Cool charm for cosmetics and care products

Merck, a leading science and technology company, is presenting Ronastar ® Frozen Jewel: this new, silvery
premium pearl luster pigment complements the Ronastar ® range with an intense frosty-brilliant shine and outstanding hiding power. The new pigment imparts a unique, intense silver sparkle to premium cosmeticsand high-quality body care products.


State-of-the-art multilayer technology

Smooth glass platelets (inorganic calcium-aluminum borosilicate) coated with multiple layers of metal oxides are the secret behind Ronastar ® Frozen Jewel: The particles with a size ranging from 20 to 200 µm provide a very high reflection of incoming light – and measurably stronger than other effect pigments with similar product properties. “Thanks to its state-of-the-art multilayer technology, even smalles concentrations of Ronastar ® Frozen Jewel develop a maximum frost effect and exceptional hiding power,” explains Alexander Peters, Head of Global Marketing Decorative Materials at Merck.


Cosmetics and care products with cool charm

The pigment shows up as a white powder with a silvery sparkle. If used on its own, Ronastar ® Frozen Jewel appears like a pure, sparkling silver – when combined with other cosmetic colorants it imparts a frosty-silvery shimmer to strong colors. This allows a broad range of applications for cosmetics and care products, providing a distinct cool, brilliant charm: The pigment innovation imparts a certain “wow” effect to loose or compact powders and eye shadows as well as lip makeup and nail polish. Thanks to its innovative frosty appearance Ronastar ® Frozen Jewel perfectly supports cool product concepts of refreshing or cooling body and shower gels.
