Solute
From Halopedia, the Halo wiki
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.[1]
