TRIS-BHT MESITYLENE
Safety grade: A
This is a synthetic antioxidant compound created in a laboratory by combining BHT (a common preservative) with mesitylene. It works to prevent oils and other ingredients in cosmetic products from breaking down and becoming rancid.
This ingredient protects cosmetic formulations from oxidation, which extends shelf life and prevents the product from degrading, discoloring, or developing an unpleasant odor over time.
