SODIUM BISULFITE

Description

Sodium bisulfite is a versatile inorganic compound widely used in skincare and cosmetic formulations. This white, crystalline substance functions primarily as an antioxidant and preservative, helping to maintain product stability and extend shelf life. In skincare, sodium bisulfite plays a crucial role in preventing oxidation of sensitive ingredients, particularly in formulations containing vitamins and other reactive compounds.

The ingredient's ability to neutralize free radicals makes it valuable in anti-aging products, where it helps protect the skin from oxidative stress. Sodium bisulfite also exhibits antimicrobial properties, inhibiting the growth of bacteria and fungi in cosmetic formulations. This dual action as a preservative and antioxidant makes it an efficient multifunctional ingredient.

In hair care products, sodium bisulfite is utilized as a reducing agent in perming and straightening treatments. It helps break and reform disulfide bonds in hair proteins, facilitating the reshaping process. However, its use requires careful formulation due to potential skin and respiratory sensitivities in some individuals. Regulatory bodies have established safe concentration limits for sodium bisulfite in various cosmetic applications to ensure product safety and efficacy.
