Dyes are organic chemicals used to color textiles, paper, leather, food, and cosmetics. They are produced from processing petroleum and coal tar chemicals like benzene. The dyestuffs that impart color penetrate fibers through chemical reactions when dissolved in water. Plastics include thermosetting plastics that harden permanently after heating and thermoplastics that soften when reheated. Rubber can be natural from rubber trees or synthetic made through polymerization and vulcanization with sulfur and carbon black added for durability. Glass is made from silica sand through high-temperature melting with other ingredients to make the melt easier to handle and shape. Soaps are salts of fatty acids made by treating fats and

3. DYES
DYES are substance that are used
to stain or give color . Most of
them are used in the textiles
industry, but are also used in the
paper, leather, food and
cosmetics industries. These
organic chemicals produced by
processing petroleum and coal tar
chemicals such as benzene. The
substances that give color to dyes
are called dyestuffs , which when
dissolved in water , penetrate the
fibers of fabrics by means of
chemical reaction

7. Thermo plastics
Soften and melt each time they are
heated and harden, keeping their shape
when the temperature falls.
Thermo setting plastics
This plastics will not soften again
once they have been heated and
set.

8. RUBBER
RUBBER may be natural or
synthetic. Natural rubber come
from rubber trees cultivated in
plantation. Synthetic rubber is
made by polymerization . It
becomes elastic and hardens
when treated with Sulphur, a
process called vulcanization. A
pigment called carbon black is
added to make the rubber
durable.

9. Glass is transparent, easy
to shape and clean, does
not rot, and resist attack
by most chemicals. It is a
product made from silica
(SiO 2 ). The common form
of silica is sand, but it also
occurs in nature in a
crystalline form known as
quartz.
Pure silica can produce an
excellent glass, but it is
very high-melting
(1,723 o C, or 3,133 o F),
and the melt is so
extremely viscous that it is
difficult to handle. All
common glasses contain
other ingredients that
make the silica easier to
melt and the hot liquid
easier to shape.

10. SOAP AND DETERGENT
Soaps are water-
soluble sodium or
potassium salts of
fatty acids. Soaps
are made from fats
and oils, or their
fatty acids, by
treating them
chemically with a
strong alkali.
In the cleaning
process, surface
tension must be
reduced so water
can spread and wet
surfaces. Chemicals
that are able to do
this effectively are
called surface active
agents, or
surfactants.

11. Abstract Chemistry has major
importance in Food Processing
sector. Food chemistry is the study
of chemical processes and
interactions between all biological
and non-biological components of
foods. It informs us about changes
in foods taking place during
processing and storage. The
chemical processes that take place
inside food determine its
nutritional value, taste, texture
and freshness. Like any other
organic material, food can
decompose over a period of time.
Various household chemicals help
in preservation of foods like use of
common salt in pickles, chutney,
sauces etc.
