Widely used in pharmaceuticals as a key component in liposomal drug delivery systems, enhancing the solubility and bioavailability of active ingredients. Commonly found in intravenous formulations where it helps protect drugs from degradation and controls release rates. Used in dietary supplements for liver support and cognitive health due to its role as a source of choline, which is involved in neurotransmitter synthesis. In cosmetics, serves as an emulsifier and skin barrier enhancer in creams and lotions, improving moisture retention and product stability. Industrial applications include use in research as a model membrane lipid for studying cell membrane behavior and interactions with proteins or drugs. Also employed in medical diagnostics and gene therapy as a non-toxic, biodegradable carrier for targeted delivery of nucleic acids or imaging agents.
