What is Linoleic acid?
Linoleic acid (CAS 60-33-3), also known as telfairic acid, is an 18-carbon polyunsaturated omega-6 fatty acid derived primarily from vegetable oils. FEMA 3380.
Where is Linoleic acid used?
- Food production: acidulant and flavoring component contributing to taste profiles of fats and oils
- Personal care: emulsion stability in skin creams and serums
- Pharmaceuticals: functional excipient in lipid-based drug delivery systems
- Industrial oleochemical processing: feedstock for conjugated linoleic acid and derivative compounds
- It also serves as a pH regulator in several manufacturing sectors.
Good to know: Purity levels commonly range from 60% to above 99% depending on the intended application. High-purity grades meeting USP or Ph. Eur. standards are available for pharmaceutical and nutraceutical use.
Commercial specifications
- Purity: 60% to above 99% depending on application
