POTASSIUM SODIUM TARTRATE

Description

Potassium sodium tartrate, also known as Rochelle salt or Seignette salt, is a double salt compound with the chemical formula KNaC4H4O6��4H2O. This crystalline substance has gained attention in skincare formulations due to its multifaceted properties. As a buffering agent, it helps maintain the pH balance of skincare products, ensuring stability and efficacy.

In skincare applications, potassium sodium tartrate functions as a chelating agent, binding to metal ions that could otherwise degrade formulations or irritate sensitive skin. This property enhances the shelf life and performance of various products. Additionally, it serves as a mild exfoliant, gently removing dead skin cells to promote a smoother, more radiant complexion.

The ingredient's hygroscopic nature allows it to attract and retain moisture, contributing to improved hydration in skincare formulations. This feature is particularly beneficial in products designed for dry or dehydrated skin. Potassium sodium tartrate also exhibits emulsifying properties, aiding in the creation of stable emulsions that blend oil and water-based components effectively.

While generally considered safe for topical use, formulators should be aware of potential sensitivities in some individuals and conduct appropriate testing before incorporating it into products.
