Sodium metabisulfite

Sodium metabisulfite is an antioxidant-based preservative that is used in cosmetics and skincare products to prevent contamination by bacteria and mold and to extend the shelf-life of products. 

Antioxidants help to prevent oxidation of products which is a natural process that occurs when oxygen takes electrons from the ingredients in the formulation, changing their composition and efficacy. Oxidation often is associated with a change in the color and texture of a product. Antioxidants donate electrons to oxygen so that it doesn’t damage the formulation.
