APPLICATIONS
|
Metallic salts of fatty acids (called soap) are primarily used as cleansing
agent (mainly sodium- and potassium-) which their molecules attach readily to
both polar molecules (of water) and non-polar molecules (of grease or oil). The
long hydrocarbon chains are non-polar (and hydrophobic) repelled by water and
the salt end molecules are ionic (and hydrophilic) water soluble. Soaps differ
according to the type of fatty acid and length of the carbon chain and according
to the alkali employed. Fatty acids with longer chains are insoluble. If sodium
hydroxide is used as the alkali, hard soaps are formed; potassium hydroxide
yields soft soaps. Soap salts are used as insecticides, herbicides, fungicides
and algaecides. The lipophilic carbon chains infiltrate
and destroy the lipoprotein matrix of the insect's cell
membranes. Food grade soap salts are used also as general
purpose food additives. Aluminum, calcium, magnesium, lead, zinc or other metals are
used in place of sodium or potassium for soaps to be used in industry. Metallic
salts of fatty acids are used as stabilizer and plasticizer in plastic industry
as well as in cosmetics. They are used as flatting and sanding agents in
lacquers, coatings & inks. They can be applied in tablet manufacturing. They
are used as drying lubricants and dusting agents for rubbers. They are used as
catalysts in chemical synthesis and emulsifiers for emulsion polymerization of
synthetic rubber and resin which can be approved for use in food contact
applications. They are used as waterproofing additives and ointments. |

GENERAL DESCRIPTION OF CARBOXYLIC ACIDS |
Carboxylic acid
is an organic compound formed from an alkyl group bonded to a carboxyl group,
-COOH, (a carbon atom is bonded to an oxygen atom by a solid bond and to a
hydroxyl group by a single bond). Examples are shown in table. In substitutive
nomenclature, their names are formed by adding -oic acid' as the suffix to the
name of the parent compound. They can yield two kinds of salts, as they contain
two carboxyl groups in its molecules. Long-chain carboxylic acids are called
fatty acids occuring as esters in fats and oils in nature. Carboxylic acids are
used as solvents and as parent materials to prepare many chemical compounds.
