SODIUM HYDROSULFITE

Description

Sodium hydrosulfite, also known as sodium dithionite, is a potent reducing agent widely used in various industries, including skincare and cosmetics. This white, crystalline powder is highly soluble in water and exhibits strong antioxidant properties. In skincare formulations, sodium hydrosulfite primarily functions as a preservative and stabilizer, helping to extend product shelf life and maintain efficacy.

The compound's reducing capabilities make it particularly effective in preventing oxidation of sensitive ingredients, such as vitamins and botanical extracts. It can also neutralize free radicals, potentially offering anti-aging benefits when incorporated into skincare products. Sodium hydrosulfite is often used in hair dyes and bleaching agents due to its ability to break down melanin and other pigments.

However, its use requires careful consideration due to its sensitivity to oxygen and potential for skin irritation in some individuals. Formulators must ensure proper pH balance and concentration when incorporating sodium hydrosulfite into skincare products. It's typically used in low concentrations, ranging from 0.1% to 1%, depending on the specific formulation and intended purpose. While effective, sodium hydrosulfite is not suitable for all skin types and should be used judiciously in skincare formulations.
