SODIUM OXALATE

Description

Sodium oxalate is a white, crystalline compound with the chemical formula Na2C2O4. As a salt of oxalic acid, it plays a significant role in various skincare and cosmetic formulations. This ingredient functions primarily as a chelating agent, helping to stabilize product formulations by binding to metal ions that could otherwise compromise the efficacy and shelf life of skincare products.

In skincare applications, sodium oxalate can enhance the performance of cleansing products by softening water and improving lather quality. Its ability to sequester calcium and magnesium ions makes it particularly useful in formulations designed for use in hard water areas. Additionally, sodium oxalate can act as a pH adjuster, helping to maintain the optimal acidity of skincare products.

While generally considered safe for topical use in regulated concentrations, it's important to note that sodium oxalate can be an irritant at high concentrations. Formulators must carefully balance its inclusion to harness its benefits without risking skin sensitization. In some formulations, sodium oxalate may also serve as a buffering agent, helping to maintain product stability across varying environmental conditions and ensuring consistent performance throughout the product's lifespan.
