Systems and methods for the production of gelled sanitizer compositions under extensional flow conditions

Abstract

Methods include producing a gelled sanitizer composition, including preparing a hydrating fluid composition including water and one or more of alcohol and peroxide; preparing a hydratable additive; and combining the hydrating fluid composition and the hydratable additive to produce a gelled composition. Methods also include flowing a hydrating liquid composition in an extensional flow regime through an elongated passageway of an extender, wherein the hydrating liquid composition includes water and a C2-C10 solvent, and a flow rate of the hydrating liquid composition and a diameter of the elongated passageway are sufficient to achieve a Reynolds number of 20,000 or greater; and adding a hydratable additive to the hydrating liquid composition in the elongated passageway to produce a mixture comprising the hydratable additive that is at least partially hydrated.
