Solution Overview

Problem

The manufacturing of solid caustic compositions is energy intensive, and they are hygroscopic, posing safety concerns during transportation and handling, while existing solid caustic compositions often require costly solid hydroxide beads and are unstable in water.

Innovation Solution

Development of solid compositions comprising an alkali metal hydroxide, an organic molecule with a hydroxyl group, and water, with a caustic:water weight ratio of 27:73 to 75:25, which can be formed in situ or pre-formed, reducing the need for solid caustic beads and using alkylene carbonates to create contiguous solid powders or granules suitable for cleaning, disinfecting, and sanitizing.
