About NANOPHASE TECHNOLOGIES Corp

Nanophase Technologies Corp. (ticker: NANX) is a United States-based specialty materials and beauty-science company. Based in Romeoville, Illinois, the company was founded in the late 1980s and originally built its platform around engineered nanomaterials before expanding into skin-health, cosmetic, and dermocosmetic applications. For investors in France, Belgium, and Switzerland, the company should be viewed as a niche small-cap operator positioned at the intersection of advanced materials, functional ingredients, and applied formulation science. Available SEC and company disclosures indicate that NANX has been trading on OTCQB rather than NYSE/NASDAQ, despite being a U.S.-listed issuer. ([sec.gov](https://www.sec.gov/Archives/edgar/data/883107/000138713120003364/nanx-10k_123119.htm?utm_source=openai)) The group now operates primarily through its wholly owned subsidiary Solésence, LLC, which is the main growth engine in beauty and life-science markets. Nanophase emphasizes a proprietary surface-treatment and dispersion technology platform, including its Active Stress Defense™ Technology, used to create mineral-based ingredients and formulations designed to protect skin from environmental aggressors. Its offering spans sunscreen ingredients, fully formulated skin-care products, and select medical-diagnostics applications. In parallel, the company continues to serve legacy advanced-materials markets such as architectural coatings, industrial coatings, abrasion-resistant additives, plastics additives, and surface-finishing/polishing technologies. That combination makes Nanophase a hybrid business: part specialty materials supplier, part formulation-driven consumer-health platform.

The company’s U.S. operating footprint is concentrated in the Chicago suburbs, with facilities in Romeoville, Burr Ridge, and Bolingbrook, all in Illinois. This geography suggests a manufacturing model centered on R&D-intensive, specialty production close to headquarters and technical resources. The headquarters and core operations are in Romeoville, Illinois, United States.

In 2024, Nanophase reported record quarterly revenue and profit, highlighting strong momentum in Solésence and improved financial performance. The company also noted industry recognition for its formulations, including repeated awards in the Cosmoprof/Cosmopack North America ecosystem, which supports the credibility of its innovation platform in prestige beauty and sun care. For equity investors, the name remains a microcap, technology-enabled specialty materials story with upside tied to intellectual property, commercialization execution, and continued demand for differentiated mineral-based beauty and life-science solutions. The main risks remain customer concentration, scale, and the need to sustain profitability as it grows.
