Introduction-

Glycerol is a trihydric alcohol, combines with fatty acid toform fat.

Glycerol is commonly called glycerol or glycerine. It is asweet-tasting alcohol that is colourless and odourless.

It melts at 18 degrees Celsius and boils at 290 degreesCelsius.

Its chemical formula is C3H8O3.

Molecules of fat contain glycerol. One way toextract it from fats or oils is through saponification

a chemical reaction involving a fat and an alkali.

A interesting property of glycerine is that it is veryhighly hygroscopic, which means that it absorbs

water from the air.

Industrial Uses-

Pharmaceutical and Personal Care Applications

Glycerol is used in medical and pharmaceuticals and

personal care preparations, mainly as a means of

improving smoothness, providing lubrication and as a

humectants.

Glycerol is a component of soap, which is used bypeople with sensitive, easily-irritated skin because it

prevents skin dryness with its moisturising properties.

Topical pure or nearly pure glycerol is an effective

treatment for psoriasis, burns, bites, cuts, rashes,bedsores, and calluses

The antiseptic qualities of this chemical make it valuable

in biological laboratories such as to preserve specimens in

jars.

Glycerine is widely used to manufacture the following

drugs.

Capsules

Suppositories

Ear infection remedies Anaesthetics

Cough remedies

As a vehicle for antibiotics and antiseptics.

Pharmaceutical and Personal Care Applications-

Foods and Beverages industry -

In foods and beverages, glycerol serves as solvent,humectants or to moisten, sweeten or preserve the food

and drinks.

It is also used as a humectants along with propylene

glycol in the production of snus, a Swedish style

smokeless tobacco product that the Swedish government

subjects to the same regulations as "food.

Some dietary advocates accept glycerine as a sweetenercompatible with low carbohydrate diets.

Cosmetics and Toiletries -

Because of the non-toxic nature of glycerin, it is

used in cosmetics and toiletries.

The sweet-tasting alcohol is found in many skin

moisturizing lotions and creams because of the water-

retaining and water-absorbing capacity.

It is used in the following products: Toothpaste

Skin creams and lotions

Pre-shaving lotions

Deodorants Lipstick

Mascara

Tobacco -

Glycerin is also used in tobacco to prevent thebreaking and crumbling during the processing of

cigarettes, etc.

It also adds some kind of flavor to the

chewing tobacco.

It is widely used to manufacture cigarette

filter tips as well.

Paper and Printing -

It is used to soften and reduce the shrinkageduring paper manufacturing.

It is used in the following:

Grease proof paper

Food wrappers

Printing ink


12/15

Textiles -

Glycerine is used in textiles to soften the yarn and to

lubricate fibres of different kinds.

In the textile industry, glycerine is generally used for

the following purposes:

As a lubricant for food processing To manufacture resin coating

To add flexibility to rubber and plastic

As a building block in manufacturing flexible

foams To manufacture dynamite

To create component that is used in radios and

neon lights


13/15

Explosive-

Glycerol is never explosive in itself but isused to produce nitro-glycerine, or glycerol-

trinitrate (GTN), which is an essential ingredient

of smokeless gunpowder and various explosives

such as dynamite, gelignite and propellants likecordite.

Nitro-glycerine a compound derived from

glycerol used to make dynamites and explosives.

Nitro-glycerine is not only used in explosives

but is found as a medication for heart disease

also.


14/15

Other

As an ingredient in antifreeze-

Like ethylene glycol and propylene glycol,

glycerol dissolved in water disrupts the hydrogen

bonding between water molecules such that the

mixture cannot form a stable crystal structure unless

the temperature is significantly lowered.As an hydraulic fluids,

Hydrogen gas production unit

Conversion to propylene glycol

Conversion to ethanol
