Products Description of Oleic acid CAS112-80-1

Oleic acid is an unsaturated fatty acid with a carbon-carbon double bond in its molecular structure. It is a constituent fatty acid of olein and the most widely distributed natural unsaturated fatty acid. Obtained through the hydrolysis of fats and oils, its chemical formula is CH₃(CH₂)₇CH=CH(CH₂)₇·COOH. Glyceryl oleate is one of the main components of olive oil, palm oil, lard, and other animal and vegetable oils. Industrial-grade oleic acid typically contains 7–12% saturated fatty acids (palmitic acid, stearic acid) and small amounts of other unsaturated fatty acids (linoleic acid).

Product Application of Oleic acid CAS112-80-1

Cosmetics and personal care are one of the main applications of oleic acid. It is an essential raw material for making soap, soap bars and body washes. In skin care products, moisturizers, and shampoos, oleic acid helps to blend water and oil (emulsify), and it also has excellent skin penetration and moisturizing effects.

It can undergo epoxidation to produce epoxy oleate, which is used as a plasticizer. Through oxidation, it can be converted into azelaic acid—a raw material for polyamide resins. Additionally, oleic acid serves as a pesticide emulsifier, printing and dyeing auxiliary, industrial solvent, metal mineral flotation agent, and mold release agent. It is also a raw material for carbon paper, ballpoint pen oil, and typing stencil paper. Various oleate products are important derivatives of oleic acid. As a chemical reagent, it is used as a chromatographic reference sample and in biochemical research for the detection of elements such as calcium, copper, magnesium, and sulfur.
