Overview
Sodium metabisulfite is a multifunctional, chemically inorganic ingredient that is supplied as a white powder.
This ingredient can serve as a preservative, as it is especially effective at preventing fungus and mold growth. Because of its limited preserving ability, it is normally combined with a strong bactericidal preservative to achieve broad spectrum protection.
Sodium metabisulfite is also an antioxidant, which means it protects sensitive ingredients from degradation as a result of free radicals created by ultraviolet light. Additionally, this ingredient is useful as a reducing agent, which is commonly seen in permanent hair processes.
