Cosmetic manufacturers are always on the lookout for new effects for their branded products. The new effect pigments, Ronastar Diamond Black and Colorona Imperial Citrine from Merck, are two of the latest product developments. With Ronastar Diamond Black the pearl-luster pigment stands out due to its rich, virtually black colour and unique shine.
This Merck innovation guarantees excellent coverage and a very pleasant, soft skin feel. The composition of Ronastar Diamond Black is based on aluminum oxide plates coated with iron oxide and silica. The smoothly formed substrate permits ideal light reflection for an even and intense sheen – comparable to that of a black diamond. Completely physically and chemically stable, Ronastar Diamond Black can be used in all cosmetic products without restrictions, especially in colour cosmetics such as mascaras, eyeliners, eye shadows, compact powders and nail polishes. The effect pigment is also suited to personal care products such as leave-in conditioners, which give dark hair a glossy shine. With Colorona Imperial Citrine, this intense yellow yet matte pigment offers formulators of skin tone cosmetics an optimum balance of transparency and colour to achieve luminosity and coverage. Colorona Imperial Citrine provides natural coverage with a delicate sheen for a fresh and vibrant look. Superior skin adhesion, a silky texture and creamy feel round off the special features of this new effect pigment. Colorona Imperial Citrine can be readily incorporated into all cosmetic formulations – from makeup and face power up to colour cosmetics.
