Integrated Family of Technologies

As a leader in the field of nanomaterials technologies, Nanophase has evolved from solely a producer of nanoparticles into an integrator of commercially scaled nanomaterial technologies focused on market and customer applications. Nanophase Technologies Corporation manufactures a variety of nanocrystalline powders in commercial quantities. The nanocrystalline metal oxides typically have a mean particle size less than 100 nm, are non-porous single crystals, have defined surface chemistry, and are chemically pure. Further modification of these materials often involves vapor-phase coating to prepare a surface-modified dry powder, or liquid phase processing to prepare a dispersion that is compatible with the application. Nanophase’s family of integrated technologies economically produces nanocrystalline materials and then nanoengineers those materials to fit customer’s needs.

Figure 1. Nanophase development process

Nanophase’s development process is designed to produce the most advantageous nanomaterials solution for an application. The foundation technologies are the patented Physical Vapor Synthesis (PVS) process and patent pending NanoArc® Synthesis (NAS) process. These processes use plasma energy to produce pure, non-agglomerated, non-porous, single-phase metal and mixed metal oxide nanoparticles at annual capacities measured in tens of thousands of kilograms per reactor. Nanoparticle size and surface chemistry can be tailored for applications as the nanomaterial is produced.

Sunscreen Formulations

Nanomaterials can act as sun blockers to protect human skin in formulations that go on smooth, silky and clear. Eliminating unnecessary exposure to the harmful UV rays of the sun has increasingly become a key health concern. But now, you can protect yourself without having to use a sticky white cream that is noticeable on the skin. Our NanoGard® zinc oxide, which is produced under cGMP conditions and is FDA approved for use as an active ingredient in personal care products, can provide effective UV attenuation while maintaining clarity in silky-smooth, non-sticky formulations. We are proud of our worldwide exclusive relationship with BASF to market our NanoGard® zinc oxide products for sunscreen applications on a global basis. Our NanoGard® zinc oxide products are also available with a variety of proprietary coatings that are designed to maximize compatibility with various formulations and bases.

Deodorant/Antiperspirant

Nanomaterials can impart antibacterial and anti-odor functionality on human skin in powder, gel, stick or spray underarm products that go on smooth without plugging the spray nozzle, caking or staining while maintaining clarity. The market trends for deodorants and antiperspirants are toward clear and highly effective formulations that are mild and non-irritating. NanoGard® zinc oxide or silver doped zinc oxides appear to be naturals for this application. Our NanoGard® zinc oxide, which is produced under cGMP conditions and is FDA approved for use as an active ingredient in personal care products, can provide effective odor and bacterial control while maintaining clarity in silky-smooth, non-sticky formulations. The anti-irritant properties of zinc oxide are an added benefit! Silver doped zinc oxide may offer an enhancement in odor fighting antibacterial properties.

Oral Care

Nanomaterials can be introduced into a variety of oral care products to impart antimicrobial and anti-irritant properties without sacrificing flow, texture or color. Dental pastes, creams and cleaners need to thoroughly clean teeth and gums, and leave a clean and crisp feeling in the mouth afterwards. Incorporating NanoGard® zinc oxide into such formulations provides antibacterial and anti-irritant properties while minimizing effects on color, flow, stickiness and wash-away characteristics. NanoGard® zinc oxide is produced under cGMP conditions and is FDA approved for use as an active ingredient in personal care products.

Shaving/Depilatory Products

Incorporation of nanomaterials in shaving and depilatory products offer improved anti-irritant properties without sacrificing flow and texture properties. The market trends for shaving creams and depilatory products are toward milder and less irritating products. NanoGard® zinc oxide, when incorporated into skin application products, has an anti-irritant effect. The use of NanoGard® zinc oxide brings the additional benefits of clarity, non-stickiness, and non-thickening and will not clog a spray nozzle. NanoGard® zinc oxide is produced under cGMP conditions and is FDA approved for use as an active ingredient in personal care products.

Foot Powder

Nanomaterials can impart antibacterial and anti-odor functionality on human skin in powder or spray formulations that go on smooth without plugging of the spray nozzle or caking. Zinc oxide is well recognized as an antimicrobial and odor absorbing product. It has been safely used for years in diaper creams and other soothing ointments. Our NanoGard® zinc oxide, which is produced under cGMP conditions and is FDA approved for use as an active ingredient in personal care products, can provide effective odor and bacterial control while maintaining clarity in silky-smooth, non-sticky formulations.
