SPF Scout · Ingredient
T-Butyl Alcohol
CAS 75-65-0
What this ingredient generally does
This is a solvent, meaning it dissolves other ingredients and keeps them evenly mixed. It also acts as a denaturant (making any alcohol in the mix undrinkable) and can add scent. In practice it helps the formula stay uniform and pourable.
Reviewed before publication. This note describes function in a formulation — nothing else.
