Cholesterol is a specialty chemical widely used in the pharmaceutical, cosmetic, and research industries. In pharmaceuticals, it serves as a key ingredient in the formulation of liposomes for drug delivery systems, enhancing bioavailability and targeted delivery of therapeutic agents. It is also a crucial precursor for the synthesis of steroid hormones (e.g., cortisol, estrogen, testosterone), vitamin D, and bile acids, which are essential for physiological functions.

In the cosmetic industry, cholesterol is incorporated into skincare products for its moisturizing and stabilizing properties, helping maintain the skin’s barrier function, prevent moisture loss, improve texture, and act as an emulsifier in creams and lotions.

In research, cholesterol is utilized to study cell membrane structure and function, playing a critical role in membrane fluidity and integrity. Its applications extend to the food industry, where it is used in dietary supplements and fortified foods. Medically, cholesterol levels serve as indicators of cardiovascular health, with elevated levels linked to heart disease risk, and it is involved in pharmaceutical research for cholesterol-modulating drugs.
