Octadecanedioic acid(CAS: 871-70-5)

Octadecanedioic acid, also known as stearic acid, is a saturated fatty acid with the chemical formula C18H36O2. It is a white, waxy solid at room temperature and is commonly used as a lubricant, emulsifier, and thickener in various industries. With a high melting point, it is stable under normal conditions and has a long history of application in cosmetics, food, and pharmaceuticals.

Octadecanedioic acid is widely used in the food industry as a stabilizer and emulsifier, in pharmaceuticals for drug formulation, and in cosmetics as a preservative and texture enhancer. It also serves as a raw material in the production of soaps, plastics, and coatings. Additionally, it is utilized in research for studying lipid metabolism and as a model compound for organic chemistry applications.

Octadecanedioic acid is generally considered safe when handled properly. It is non-toxic in normal use but should be treated with care to avoid skin contact and inhalation. In industrial settings, appropriate safety measures such as gloves and ventilation are recommended. It complies with food-grade safety standards when used within regulated limits.

Octadecanedioic acid should be stored in a cool, dry, and well-ventilated area away from direct light. It is best kept in a sealed, airtight container to prevent moisture absorption. Due to its stability, it does not degrade easily, but proper storage ensures long shelf life and maintains its chemical integrity.
