METHYL STEARATE.

Valuable CAS 112-61-8 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Methyl Stearate is a versatile ester functioning primarily as an emollient and skin-conditioning agent. It effectively softens and smooths the skin by integrating into the skin's surface, enhancing suppleness and reducing flakiness, while also forming a protective barrier to minimize moisture loss. Beyond its skin benefits, it significantly contributes to product formulation as an emulsifier and stabilizer, improving texture and consistency.

Summary

Emollient Skin-Conditioning Agent Emulsifier Stabilizer Surfactant (nonionic) Fragrance functional ingredient

Science

Mechanism of Action

Methyl Stearate acts by filling microscopic gaps between skin cells, which diminishes flakiness and promotes a smoother, more supple skin texture. Upon topical application, it establishes a surface barrier that effectively locks in moisture, thereby enhancing skin hydration. Furthermore, its role as a nonionic surfactant and emulsifier is crucial for blending oil and water phases, ensuring product stability and desirable texture.
