Having monitored global markets by August 2020, the Nanotechnology Products Database (NPD) identified 222 nano-enabled or nano-enhanced products developed using nanoclay, which had been registered by 125 companies from 25 countries. The nanoclays and organoclays observed in these products were mainly based on montmorillonite and bentonite nanoparticles, and halloysite nanotubes. According to the NPD, the United States, China, Japan, India, the United Kingdom, Russia, and South Korea were major manufacturers of products containing nanoclay. These products, including rheology modifiers, nanocomposites, water filtration media, car wash products, toothpaste and mouthwash, drilling mud, food packaging films, tires, greases, lubricants, polishes, tennis balls, cosmetics and their additives, paints, thermal insulation coatings, cables, inks, asphalt additives, screws, panels, board fences, glues, and syringes were developed or enhanced using nanoclay so as to show improved properties in terms of mechanical strength, thermal stability, anti-settling properties, ultraviolet scattering, permeability to gases, photostability, rheology modification, viscosity control, surface contaminant removal, hydrophobicity, oil resistance, chemical resistance in acidic or alkaline media, corrosion and oxidation resistance, anti-bacterial, anti-microbial, and antifungal properties, and biodegradability.
