What this ingredient generally does

Triacetin is a multi-tasker: it works as a solvent to dissolve other ingredients, forms a thin film on the skin, keeps microbes in check, keeps the formula flexible, and adds fragrance. In practice it helps carry and hold the formula together while leaving a light layer on the skin.
