"Explore Oleic Acid (CAS 112-80-1), a high-purity omega-9 fatty acid widely used in cosmetics, pharmaceuticals, and industrial formulations. Discover its benefits, applications, and safe usage."
-Deshangchemical
Oleic acid, also known by its CAS number 112-80-1, is a monounsaturated omega-9 fatty acid widely used across multiple industries due to its excellent emulsifying, solubilizing, and stabilizing properties. As a naturally occurring component in animal fats and vegetable oils—particularly olive oil and sunflower oil—oleic acid plays a key role in both biological functions and industrial formulations.
Product Overview and Chemical Properties
Oleic acid (C18H34O2) is a clear, colorless to pale yellow oily liquid with a mild odor. It is insoluble in water but miscible with most organic solvents such as ethanol and chloroform. Its chemical stability and high purity make it suitable for a wide range of applications, particularly in formulations where mildness and biocompatibility are required.
Applications of Oleic Acid
Cosmetics and Personal Care
Oleic acid serves as a crucial ingredient in skin creams, lotions, soaps, and hair conditioners due to its moisturizing and skin-penetration abilities. It helps deliver active ingredients deep into the skin and improves texture and viscosity in formulations.
Pharmaceuticals
In the pharmaceutical sector, oleic acid is used as an excipient in topical ointments, transdermal drug delivery systems, and oral capsules. Its role as a permeation enhancer makes it valuable for transdermal drug delivery.
Food Industry
Oleic acid is used as a flavoring agent and emulsifier in food-grade formulations. It is also a major component of edible oils and has been associated with potential health benefits, including cardiovascular protection.
Industrial Uses
In industrial manufacturing, oleic acid is used as a lubricant, surfactant, and corrosion inhibitor. It also plays a role in producing synthetic esters, plasticizers, and alkyd resins for paints and coatings.
Safety and Handling
Oleic acid is generally recognized as safe (GRAS) for use in food and cosmetic products. However, proper storage is necessary to maintain its quality—recommended conditions include a cool, dry, and well-ventilated area away from heat and light. Although it is not classified as hazardous, direct skin or eye contact should be avoided during handling in industrial settings.
Conclusion
Oleic Acid (CAS 112-80-1) continues to be a high-demand multifunctional ingredient in modern industries. From personal care and pharmaceuticals to food and industrial manufacturing, its versatility, safety profile, and natural origin make it a cornerstone ingredient in countless formulations.
