EPOXIDIZED SOYBEAN OIL

Description

Epoxidized soybean oil (ESO) is a versatile ingredient derived from soybean oil through an epoxidation process. This modification enhances its stability and functional properties, making it valuable in skincare formulations. ESO acts as an effective emollient and occlusive agent, forming a protective barrier on the skin to prevent moisture loss and improve hydration.

The compound contains epoxy groups that contribute to its antioxidant properties, potentially helping to neutralize free radicals and combat oxidative stress in the skin. ESO's molecular structure allows it to penetrate the stratum corneum, supporting skin barrier function and enhancing overall skin health.

In skincare products, ESO serves as a natural alternative to synthetic plasticizers and stabilizers. It improves the texture and spreadability of formulations while adding a smooth, non-greasy feel. The ingredient's low irritation potential makes it suitable for sensitive skin types.

ESO also demonstrates compatibility with various active ingredients, potentially enhancing their delivery and efficacy. Its film-forming properties can contribute to the longevity of topical treatments on the skin surface. When used in appropriate concentrations, epoxidized soybean oil can contribute to improved skin texture, elasticity, and overall appearance.
