Science
Mechanism of Action
As a skin conditioning agent, PPG-25 Sorbitol helps to maintain the skin’s optimal state. Its sorbitol-derived structure enables it to act as a humectant, actively attracting and binding water molecules to the stratum corneum, thus promoting deep hydration and a smoother skin texture. Furthermore, the polypropylene glycol component is instrumental in cosmetic formulations, providing solubilizing, solvent, and emulsifying properties essential for creating stable oil-in-water mixtures.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Sorbitol itself is safe for cosmetic applications. For polypropylene glycols (PPGs) with three or more molecular units, including PPG-25 Sorbitol, the CIR Panel deemed them safe when formulated to be non-irritating. A safety assessment of related PPG Stearyl Ethers supported their safety at concentrations up to 25%. The US FDA lists Sorbitol as Generally Recognized As Safe (GRAS) for human consumption.
