Sodium Lactate is the sodium salt of lactic acid and is commonly used in cosmetic and personal care formulations for its moisture-binding and formulation-supporting properties. As a humectant, it helps attract water and maintain hydration in compatible skincare and haircare products.
In cosmetic formulation development, Sodium Lactate can be incorporated into suitable moisturizers, lotions, creams, gels, cleansers, and haircare products. It can also contribute to pH buffering in appropriate formulation systems. Its performance depends on the supplied concentration, formulation pH, ingredient compatibility, and the requirements of the finished product.
Sodium Lactate is commonly available as an aqueous liquid solution, although product specifications can vary by supplier. Formulators should verify the concentration, purity, and physical properties of the supplied grade before preparing a formulation.
For reliable results, consult the manufacturer’s Technical Data Sheet (TDS) for the recommended usage level, pH range, compatibility, and processing instructions.
