Disodium Azelate
What is Disodium Azelate?
Disodium azelate is the disodium salt of azelaic acid, a straight-chain dicarboxylic acid naturally present in grains such as wheat and barley, and produced by certain yeasts. This water-soluble form enhances its compatibility in aqueous cosmetic systems. Primarily functioning as a viscosity controlling agent, it modulates the thickness of formulations like lotions, creams, and gels. By influencing rheological properties, it ensures products maintain consistent flow, resist settling of particles, and spread evenly during use. This role promotes physical stability over time, preventing phase separation and supporting suspension of other ingredients. Its inclusion allows formulators to achieve desired sensory attributes, such as silky feel and easy dispensing, across diverse product types without compromising usability or shelf life. Derived from established chemical processes, it aligns with standard cosmetic chemistry practices.
