Science
Mechanism of Action
This ingredient functions as the potassium salt of caprylic (octanoic) and capric (decanoic) acids. Its surfactant properties allow it to act as a cleansing agent, while its emulsifying capabilities ensure the uniform dispersion of oil and water phases in cosmetic products. As a hydrotrope, it enhances ingredient solubility in water, and it conditions the skin for a smooth feel. Additionally, it contributes to extending the shelf life of formulations through its mild preservative action.
