Ronastar Sparks The Sparkling Collection evolves

Following the launch of the Ronastar® brand of effect pigments in 2004, Merck KGaA have now expanded the innovative range with the introduction of four new interference pigments and one new silver-white for cosmetic and personal care products. The pigments exhibit attractive properties such as; high brilliance and gloss, high transparency, multi-colour sparkling effects. The slightly smaller particle size of Ronastar® Silver gives a smooth, pleasant skin feel.

The new creations are easily incorporated into all cosmetic applications including; emulsions, powders, gels, sticks, anhydrous creams, as well as in nail lacquers. Intense sparkling effects can be achieved with very small amounts of the Ronastar® Sparks range making these products undeniably efficient.

The substrate, Calcium Aluminium Borosilicate forms the basis of the Ronastar® family, this unique thin, smooth and uniform platelet allows the development of new and improved pearlescent effects. Varying particle sizes result in glossy, shimmering and high sparkle effects. Additionally, coatings of metal oxides at different layer thicknesses generate diverse colour properties. Each new creation offers new dimensions of brilliance for cosmetic and personal care formulations.
