Ashland Specialty Ingredients has introduced Aquarius coating systems' natural colors palette designed to meet the regulatory requirements of the nutraceutical industry. Nutraceuticals are subject to food regulations, which are more restrictive than their pharmaceutical counterparts with regard to the permitted colorants. Derived from vegetable, animal and mineral sources, the organic and inorganic compounds that make up the Aquarius coating systems natural colors palette can be combined with Ashland's Aquarius MG coating systems' moisture-guard line.
