Solute

Solute is a Forerunner substance.

Overview
The purpose of the solute was to cause every animal killed by the Halo Array to instantly decay into their component molecules. This was meant to prevent pollution of the atmosphere due to decomposition. It was spread over many of the planets before the Halos were activated. Catalog observed solute being released on Erde-Tyrene during the Forerunner-Flood war as the Lifeworkers oversaw the indexing of the planet as part of the Conservation Measure.
