• Did you know2024

  The aluminum chlorohydrate (ACH) that Summit Reheis manufactures for antiperspirant use — plugging eccrine sweat pores in human armpits to reduce perspiration — is the same chemical compound, at lower purity grades, used by municipal water treatment plants as a coagulant to remove turbidity, bacteria, and organic compounds from drinking water. Polyaluminum chloride (PAC), a closely related aluminum hydrolysis product Summit Reheis also produces, is used by water utilities processing hundreds of millions of gallons per day. The chemistry is identical: aluminum ions in aqueous solution hydrolyze to form Al(OH)₃ polymeric flocs that adsorb negatively charged particles and bacteria — whether those particles are suspended sediment in a river drawn for municipal water supply or protein secretions at human skin pores. Summit Reheis simultaneously supplies: P&G's Secret and Old Spice antiperspirant manufacturing lines; Unilever's Dove and Degree formulation plants; and municipal water utility treatment plants in the US and globally. A Summit Reheis production disruption would force consumers to choose between ineffective deodorant and — for water utilities unable to switch coagulants quickly — compromised drinking water treatment.

• Concentration2024

  Aluminum zirconium tetrachlorohydrex glycine (AZTG) — the dominant active ingredient in US antiperspirant products — is regulated as an FDA OTC drug ingredient under the Antiperspirant Drug Products Monograph. This means the specific grade, formulation, and clinical efficacy data for AZTG must be registered with the FDA, and consumer product manufacturers must qualify specific supplier grades in their formulations. Switching antiperspirant active suppliers requires clinical efficacy testing and FDA notification — typically a 12-24 month process. This regulatory lock-in makes Summit Reheis's position as a primary AZTG supplier extremely durable: P&G, Unilever, Henkel, and Colgate-Palmolive have all qualified Summit Reheis grades into their formulations. If Summit Reheis had a prolonged production outage, these companies would face a choice between temporarily removing antiperspirant efficacy claims from their products (downgrading to deodorant, which is a cosmetic not a drug) or delaying production until alternative supply was qualified. The global antiperspirant market (~$15-20B retail) depends on a small number of qualified AZTG suppliers, with Summit Reheis as the dominant North American source.

• Origin2024

  Summit Reheis's lineage traces through the Reheis Chemical Company, which pioneered the development of aluminum chlorohydrate (ACH) in the late 1940s as a replacement for aluminum chloride in antiperspirant formulations. Aluminum chloride was the original effective antiperspirant compound but caused severe skin irritation and degraded fabric. Reheis Chemical developed the partially neutralized aluminum chloride (ACH) that retained antiperspirant efficacy while being skin-tolerant — enabling the modern roll-on, stick, and spray antiperspirant industry. The invention of ACH is the underlying chemistry that made the post-WWII US antiperspirant market possible; every Degree, Secret, Old Spice, and Dove antiperspirant on US shelves traces its active ingredient to Reheis Chemical's midcentury chemistry research. Summit Chemical and Reheis merged to form SummitReheis. The company holds proprietary manufacturing processes and product specifications that are qualified into the regulatory formulations of every major US consumer products company — qualification means that switching suppliers requires FDA-regulated testing and reformulation of the consumer product, creating durable lock-in.
