Description Of Business
Description of Business	(4) Description of Business Nanophase is a skin and sun care focused company that offers engineered materials, formulation development and commercial manufacturing with an integrated family of technologies. We look at our products in three major product categories; Personal Care Ingredients, including sunscreens as active ingredients; Solésence, including full formulations of skin care products, marketed and sold by our wholly-owned subsidiary, Solésence, LLC (“Solésence,” or our “Solésence^®subsidiary”); and Advanced Materials, including architectural and industrial coating applications, abrasion-resistant additives, plastics additives, medical diagnostics, and a variety of surface finishing technologies (polishing). We target markets in which we believe practical solutions may be found using our products. We work closely with current and potential customers in these target markets to identify their material and performance requirements and market our materials to various end-use applications manufacturers, and our Solésence^® products to cosmetics and skin care brands. Recently developed technologies have made certain new products possible and opened potential new markets. During 2015 we were granted a patent on a new type of particle surface treatment (coating) — now called Active Stress Defense™ Technology — which became the cornerstone of our new product development in personal care, with first revenue recognized during 2016. In addition, through the creation of our Solésence^® subsidiary, we utilize this particle surface treatment to manufacture and sell fully developed solutions to targeted customers in the skin care industry, in addition to the ingredients we have traditionally sold in the personal care area. Although our primary strategic focus has been the North American market, we currently sell material to customers overseas and have been working to expand our reach within foreign markets. The Company was incorporated in Illinois on November 25, 1989, and became a Delaware corporation during November 1997. Our common stock trades on the OTCQB marketplace under the symbol NANX. While product sales comprise the majority of our revenue, we also recognize revenue from other sources from time to time. These activities are not expected to drive the long-term growth of the business. For this reason, we classify such revenue as “other revenue” in our Consolidated Condensed Statements of Operations, as it does not represent revenue directly from the sale of our products.
