Cholesterol pelargonate is widely used in the formulation of liquid crystals, particularly in display technologies such as LCDs (liquid crystal displays). Its ability to form stable mesophases makes it a valuable component in creating responsive and efficient display screens. Additionally, it is employed in research and development to study phase behavior and molecular interactions in liquid crystal systems. In cosmetic and personal care products, it acts as an emulsifier and stabilizer, enhancing texture and consistency in creams and lotions. Its biocompatibility also makes it suitable for use in pharmaceutical applications, where it can be incorporated into drug delivery systems to improve solubility and bioavailability.
