Oleic Acid is an organic fatty acid with the chemical formula C₁₈H₃₄O₂ and CAS Number 112-80-1. It is commonly supplied as a colourless to pale yellow oily liquid, although its appearance may vary depending on purity and storage conditions. It is practically insoluble in water but soluble in many organic solvents. Oleic Acid contains one cis double bond at the ninth carbon position, classifying it as a monounsaturated fatty acid.

Oleic Acid is valued as a source of unsaturated fatty acids in biochemical reactions and chemical formulations. Common laboratory applications include lipid analysis, fatty acid profiling, biochemical studies, preparation of emulsions, surfactant research, and investigations involving lipid metabolism. It is also used in organic chemistry experiments and research involving fatty acid derivatives and esterification reactions.

Its chemical structure and amphiphilic properties make Oleic Acid useful in biochemistry, analytical chemistry, lipid research, materials science, and general laboratory applications. It may also be used in specialised formulations, cosmetic research, pharmaceutical research, and the preparation of oleate compounds. The appropriate grade and purity should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Oleic Acid may cause mild skin and eye irritation, particularly with prolonged contact. Avoid direct contact with the eyes and unnecessary skin exposure. Handle it using appropriate personal protective equipment, including laboratory gloves and safety goggles. Clean spills promptly to prevent slippery surfaces and follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
