Dodecyl stearate is widely used as an emollient and lubricant in the formulation of personal care products such as creams, lotions, and hair care items. It helps to soften and smooth the skin by forming a protective barrier, reducing moisture loss and improving texture. In cosmetics, it acts as a thickening agent and stabilizer, enhancing the consistency and spreadability of products. Additionally, it is employed in industrial applications as a plasticizer and lubricant for polymers, improving their flexibility and processing properties. Its non-greasy nature makes it a preferred ingredient in skincare formulations for a lightweight, smooth feel.
