Fatty acid are one of the most well-known
Fatty acid contains a mixture of palmatic acid, stearic acid, oleic acid, linoleic acid & linoleneic acid, These are mixture of saturated and unsaturated fatty acid with variable percentage and depending upon this percentage iodine value of the mixed fatty acid is decided.
Fatty acid is useed for food and nutrition applications & in oleochemical industry (pharmaceutical and food industries) and for producing soaps, detergents, personal care products, lubricants, paints and biodiesel.
In the refining of crude edible oils the free fatty acids are removed by agitation with alkali. The fatty acids settle to the bottom as alkali soaps and are known as soapstock or ‘foots’, soapstock could be used to manufacture soap directly or laundry detergent and paints and coatings.
Acid oil that is basically a by-product while refining crude Edible oil. During the refining process we get soap stock on which sulphuric treatment is performed which then converts soap stock into acid oil. This acid oil is widely used in the production of soaps and detergents and It enters into industry of bio diesel.
