Oleic acid CAS112-80-1
1. Naturally Abundant & Plant-Derived:
As the most abundant naturally occurring unsaturated fatty acid, primarily sourced from plants (e.g., sunflower, olive oil), it offers a renewable and biocompatible raw material.
2. Versatile Solubility & Emulsification:
Highly miscible with common organic solvents (ethanol, ether, acetone, DMSO) and possessing lipophilic properties (HLB=1), it acts as an effective emulsifier, lubricant, and carrier.
3. Broad Application Stability:
Remains liquid across a wide temperature range (melting point ~14°C, boiling point 360°C) and is stable under recommended storage (-20°C), suitable for diverse industrial processes.
4. Commercially Accessible Grade:
Available in standardized commercial grades (containing defined levels of saturates/other unsaturates) with bulk ordering options (MOQ: 1 FCL), ensuring consistent supply for industrial use.
Oleic acid is a monounsaturated fatty acid characterized by a carbon-carbon double bond in its molecular structure. This fatty acid serves as the primary component of olein and represents the most abundant naturally occurring unsaturated fatty acid. It can be extracted through the hydrolysis of various fats and oils, with its chemical structure represented as CH3(CH2)7CH=CH(CH2)7·COOH.
Oleic acid glycerides constitute a major constituent in numerous vegetable and animal oils, including olive oil, palm oil, and lard, as documented in chemical references. Commercial-grade oleic acid typically contains 7-12% saturated fatty acids (primarily palmitic and stearic acids) along with minor quantities of other unsaturated fatty acids (such as linoleic acid).
