LAUNDRY SOAPS AND
DETERGENTS
Soaps are the sodium salts of fatty acids and are
made by reacting
natural oils with sodium hydroxide or another
caustic alkali. All soaps contain water but not more
than 30% in good soaps.

The following criteria must be kept in mind while
selecting laundry soaps:
The soap should be of clear pale colour as dark colour
soaps may contain impurities that are not easily visible
The soap should feel firm when pressed. If it feels soft,
it may contain excessive amounts of water and will be
wasteful in use.
Many hard soaps, especially cheap brands, on the
other hand, contain an excess of fillers such as sodium
silicate to disguise the low percentage of soap.
A good laundry soap dries to form a firm, unspeckled
surface. Soaps that develop white crystals on the
surface should not be used, as this shows an excess
of harmful alkalis.

DRY CLEANING
This is the cleaning of fabrics in a substantially
non – aqueous liquid medium. Dry cleaning
removes oil as well as many water soluble and
some insoluble materials with the help of
detergents and various other agents.
Unlike laundering dry cleaning does not cause
swelling of the fibres and so does not lead to
shrinkage, wrinkles and bleeding of colours. Dry
cleaning is thus a safe mode for cleaning
delicate textiles.

ADVANTAGES OF DRY
CLEANING
Dry cleaning clothes for which laundering is not
suitable
It causes no shrinkage (which is often seen in
laundering)
Dry cleaning does not flatten the pile of fabrics
such as velvet
Finishes such as moireing are retained even after
dry cleaning
Colours do not bleed on dry cleaning
Stains are more readily removed by dry cleaning

DISADVANTAGES OF DRY
CLEANING
Dry cleaning is expensive
compared to laundering
Many dry cleaning solvents are
harmful to health if inhaled for long
durations
After cleaning with solvents, a
certain unpleasant smell tends to
be retained by the articles.
