INTRODUCTION

Linoleic acid is a polyunsaturated omega-6 fatty acid. It is a colorless liquid that is virtually insoluble in water but soluble in many organic solvents. It typically occurs in nature as a triglyceride (ester of glycerin) rather than as a free fatty acid.

Manufacture

Linoleic acid is obtained from the hydrolysis -chemical decomposition in which a compound is split into other compounds by reacting with water- of vegetable oils rich in linoleic acid (mainly sunflower and soybean oils). The obtained fatty acid is purified by further distillation.

Structure

APPLICATIONS

Linoleic acid finds extensive uses in various industries:
Cosmetic: protects the skin against loss of water and hence is used in moisturizers; it has anti-inflammatory properties and is used for acne reduction.
Industrial: In the paints industry for manufacture of quick-drying oils  which are used in oil paints and varnishes; making soaps, emulsifiers, and surfactants; to manufacture Arachidonic acid which has several health benefits.
Pharmaceutical: Since it is an essential fatty acid, it is used as a dietary supplement.
