GENERAL
DESCRIPTION: Calcium
Stearate is used as a stabilizer for plastics with co-stabilizer
of Ba-Cd soap. It is also used as a plasticizer in plastic
industry as well as in cosmetics. It is used as a flatting
and sanding agent in lacquers,
coatings
& inks. It is applied in tablet
manufacturing. It is used as a drying lubricant and
dusting agent for rubbers. It is used as a catalyst
in chemical synthesis. It is used as a waterproofing
additive in concrete, rockwool, textiles and paper.

GENERAL
DESCRIPTION OF METALLIC SALTS OF FATTY ACIDS
|
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 FATTY ACID
|
Fatty
Acids are aliphatic carboxylic acid with varying length
hydrocarbon chains at one end of the chain joined to
terminal carboxyl (-COOH) group at the other end. The
general formula is CnH2n+1COOH
or R-(CH2)n-COOH.
Fatty acids are predominantly unbranched and those with
even numbers of carbon atoms between 12 and 22 carbons
long react with glycerol to form lipids (fat-soluble
components of living cells) in plants, animals, and
microorganisms. Fatty acids all have common names respectively
like lauric (C12), MyrIstic (C14), palmitic (C16), stearic
(C18), oleic (C18, unsaturated), and linoleic (C18,
polyunsaturated) acids. The saturated fatty acids have
no solid bonds, while oleic acid is an unsaturated
fatty acid has one solid bond (also described as olefinic)
and polyunsaturated fatty acids like linolenic acid
contain two or more solid bonds. Lauric acid (also
called Dodecanoic acid) is the main acid in coconut
oil (45 - 50 percent) and palm kernel oil (45 - 55 percent).
Nutmeg butter is rich in myristic acid (also called
Tetradecanoic acid ) which constitutes 60-75 percent
of the fatty-acid content. Palmitic acid(also called
Hexadecylic acid ) constitutes between 20 and 30 percent
of most animal fats and is also an important constituent
of most vegetable fats (35 - 45 percent of palm oil).
Stearic acid ( also called Octadecanoic Acid)
is nature's most common long-chain fatty acids, derived
from animal and vegetable fats. It is widely used as
a lubricant and as an additive in industrial preparations.
It is used in the manufacture of metallic stearates,
pharmaceuticals, soaps, cosmetics, and food packaging.
It is also used as a softener, accelerator activator
and dispersing agent in rubbers. Oleic acid (also called
octadecenoic acid) is the most abundant of the unsaturated
fatty acids in nature. |
