Science
Mechanism of Action
This ingredient operates as an effective film-forming agent, establishing a continuous, imperceptible barrier that shields the skin from external stressors, including environmental pollutants and chemicals. Its inherent lipophilic properties enable it to act as an occlusive skin conditioning agent, profoundly reducing transepidermal water loss and aiding in the restoration of elasticity in compromised or dry skin. Furthermore, POLY(C20-28 OLEFIN) modifies the skin's surface by repelling both oils and water, which helps prevent superficial epidermal imperfections. Within formulations, it serves as a non-aqueous viscosity-enhancing agent, promoting chemical and physical stability by mitigating sedimentation, and also functions as a binder, imparting anti-caking qualities for a refined, homogenous product texture.
