Description
A clear, oily, mono-unsaturated fatty acid that occurs naturally in almost all animal and vegetable fats and oils. As the glyceride, oleic acid is a basic foodstuff. Oleic acid darkens on exposure to light and turns rancid on exposure to air. It can be hydrogenated to form stearic acid or saponified with alkalis, such as potassium hydroxide, or triethanolamine, to make soaps. Oleic acid is also used to make Turkey red oil, to waterproof textiles, to oil wool, and in the manufacture of polishing compounds.
