Used in cosmetic and pharmaceutical formulations for its skin-conditioning properties. Enhances skin barrier function by supporting lipid structure in the stratum corneum. Frequently included in anti-aging and moisturizing products due to its ability to improve skin hydration and elasticity. Also serves as a biocompatible surfactant in drug delivery systems, particularly in liposomal formulations where it helps stabilize membrane structure and improve cellular uptake. Shows potential in dermatological treatments for dry and sensitive skin conditions owing to its natural presence in cell membranes and mild irritancy profile. Additionally, utilized in biochemical research for studying cell membrane dynamics and lipid-protein interactions.
