Coating and excipient supplier Colorcon has announced the launch of a mineral-free addition to its Nutrafinish range of film coatings for the nutritional and dietary supplements market.

The latest addition to the Nutrafinish, label friendly product line is formulated without the use of TiO2, talc and calcium carbonate to deliver a high level of opacity to cover unsightly or dark tablet cores.

The coatings are aimed to help manufacturers satisfy consumer demand for sustainable ingredients that can achieve label friendly status without compromising on product quality, manufacturing efficiency, or cost-in-use, the company says.

Kelly Boyer, VP, Film Coatings said: “The launch of Colorcon’s new mineral-free formulations provides the nutritional market with alternative coating systems that combines superior opacity with excellent stability especially when using non-synthetic colourants. This product line expansion includes a new white formulation, which delivers superior opacity and the option to pigment using non-synthetic colours enables a broad choice of the colour palette to provide aesthetics and brand differentiation”.

Dr Ali Rajabi-Siahboomi, Vice President and CSO adds: “Getting the right balance of components for this type of coatings is challenging without the use of opacity and whitening ingredients like TiO2 and calcium carbonate. Through Colorcon’s in-depth knowledge of materials and coating technology, these new formulations provide simple preparation and use, with the label friendly claims the industry and consumers are demanding; along with a perfectly finished tablet.”
