LAUNDRY SOAPS AND DETERGENTSSoaps 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 visibleThe 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 CLEANINGThis 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 cleaningStains are more readily removed by dry cleaning

DISADVANTAGES OF DRY CLEANING

Dry cleaning is expensive compared to launderingMany dry cleaning solvents are harmful to health if inhaled for long durationsAfter cleaning with solvents, a certain unpleasant smell tends to be retained by the articles.
