octadecanoic acid(CAS: 57-11-4)

Octadecanoic acid, also known as stearic acid (CAS: 57-11-4), is a saturated fatty acid with the chemical formula C18H36O2. It is a white, waxy solid with a high melting point (around 70°C). Commonly found in animal and plant fats, it is used as a lubricant, emulsifier, and stabilizer. Its long hydrocarbon chain makes it hydrophobic, while the carboxylic acid group allows reactivity in chemical processes. It is widely applied in cosmetics, food, and industrial sectors due to its versatile properties.

Octadecanoic acid (CAS: 57-11-4) is used in pharmaceuticals as an excipient for tablets and topical formulations. In industry, it serves as a lubricant and plasticizer in manufacturing. In food, it acts as an emulsifier in margarine and shortenings, enhancing texture. It is also employed in cosmetics for creams and lotions. Additionally, it functions as a model compound in research for studying lipid metabolism and material science. Its applications span multiple fields due to its chemical stability and functional versatility.

Octadecanoic acid (CAS: 57-11-4) is generally safe when used within regulated limits. It is non-toxic in food-grade applications and considered safe for industrial use with proper handling. However, direct skin contact or inhalation may cause mild irritation. Safety protocols include using gloves and goggles when working with large quantities. It adheres to safety standards for cosmetics and pharmaceuticals, ensuring minimal risk when following guidelines.

Octadecanoic acid (CAS: 57-11-4) should be stored in a cool, dry place (ideally below 25°C) and protected from light. Keep in airtight containers to prevent moisture absorption, which can lead to hydrolysis. Avoid high humidity to maintain stability. Store in a well-ventilated area away from heat sources. Proper storage ensures longevity and safety, preventing degradation or contamination.
