SODIUM SULFITE

Description

Sodium sulfite is a versatile inorganic compound widely used in skincare and cosmetic formulations. This white, crystalline solid acts as a potent antioxidant and preservative, helping to extend the shelf life of various products. Its primary function is to prevent oxidation, which can lead to discoloration and degradation of active ingredients.

In skincare, sodium sulfite serves multiple purposes. It acts as a reducing agent, effectively neutralizing free radicals that can cause premature aging and skin damage. This property makes it valuable in anti-aging formulations. Additionally, sodium sulfite helps maintain the stability of vitamin C in skincare products, preserving its efficacy.

The ingredient also functions as a pH adjuster, helping to balance the acidity of formulations. This is crucial for maintaining product integrity and ensuring optimal skin compatibility. Sodium sulfite can also act as a skin-conditioning agent, contributing to improved texture and feel of skincare products.

While generally considered safe for use in cosmetics, some individuals may experience sensitivity to sulfites. It's important to note that sodium sulfite is regulated in many countries, with limitations on its concentration in leave-on and rinse-off products to ensure safety and efficacy.
