We take pride in making products that help make people's lives better, safer and healthier (PDF). Arch and its subsidiaries have leadership positions in two business segments: Treatment Products and Performance Products. But at heart, we are a Biocides company. We're a global leader in providing innovative, chemistry-based solutions to control the growth of harmful microbes. Our concentration is in water, hair and skin care products, pressure-treated wood, paints and building products, and health and hygiene applications. Our Biocides portfolio includes four businesses within our core Treatment Products business segment: Water Products. Arch's sanitizers and related treatment chemicals destroy harmful, even life-threatening microbes in recreational pool and water, drinking water, and water used in commercial and industrial applications, such as food disinfection and beverage bottle cleaning operations. Wood Protection. Our advanced preservatives protect wood from, among other things, fungal decay, insect damage and fire damage. Industrial Biocides and Health and Hygiene Products. Our biocides are incorporated into industrial, commercial and consumer products worldwide to provide protection against fungus, bacteria, viruses, algae and other harmful microbes. For instance, Arch supplies biocides for use in paints and other building products to deter the growth of mold and mildew, leading causes of the Sick Building Syndrome. Personal Care Products. Our biotechnological active ingredients, botanicals, preservatives and other cosmetic ingredients provide healthful benefits in hair and skin care products. Arch's zinc Omadine?, for example, is the world's most popular active antidandruff shampoo agent.
