Science

Mechanism of Action

As a polypropylene glycol (PPG) derivative, PPG-18 Diglyceryl Ether functions as a potent skin conditioning agent, actively contributing to the maintenance of healthy skin. It draws moisture to the skin, effectively preventing dryness and flakiness, thereby imparting a sensation of increased softness, smoothness, and sustained hydration. Beyond its direct skin benefits, it acts as a solubilizer and solvent, ensuring optimal dispersion and stability of other components within cosmetic emulsions.
