Emollient Cleansing Surfactant Emulsifying Hydrating Softening Antioxidant

Science

Mechanism of Action

This ingredient functions as a non-ionic surfactant, effectively cleansing the skin and hair while maintaining excellent dermal compatibility. It provides significant emollient, hydrating, and softening benefits, particularly for rough, dry, or dehydrated skin. Rich in antioxidants like vitamin E, it contributes to mitigating the skin aging process and the formation of wrinkles. The presence of ceramides further enhances hydration and softens the skin's surface. Its cottonseed oil base offers a balanced linoleic to oleic acid ratio, critical for robust skin barrier function and oxidative stability through phytosterols and tocopherols. Palmitic acid content aids in moisture retention, while linoleic acid may help regulate sebum production.
