How it is correct to choose laundry detergent?

Each powder wash better or worse these or those pollution. Therefore we will understand, first of all, them.

Usual dirt .

Waste products of the person: stalemate allocations, the remains of the peeled skin, bacteria. They form an insoluble oil film in water which absorbs the painted dust particles on fabrics.

Food pollution .

Arise at preparation and at absorption of food. Their nature is various, as well as our food: oils and fats, starch and cellulose, protein, dyes. Often pollution have the mixed character (that is drunk, pour).

of Pollution from environment .

All this that around us: dust of any origin, soot and products of combustion of automobile fuel, an atmospheric precipitation, road dirt, greens, flower pollen, a grass - all that leaves spots.

A basis of the washing effect of powder are superficially - active agents (surfactant). They contact particles of pollution on fabric and transfer them to solution. Their action is strengthened by additives which interfere with repeated sedimentation of dirt on fabric, eliminate hardness of water, soften fabrics after washing.

Often simple powders not completely cope with difficult removed spots.

from tea, coffee, vegetables and berries are necessary For removal of spots the bleaching substances.

For removal of spots from chocolate, sauces, lipstick, blood, an egg yolk contain high quality laundry detergents biologically - active agents - enzymes.

At the choice of laundry detergent it is not bad to consider existence in a family of children. Children, as a rule, more adults soil clothes and can not always explain the nature of an origin of spots.

Upward

Of course, at the choice of laundry detergent it is necessary to distinguish a type of washing: manual or in the washing machine. For automatic washing machines the powders " are issued; " submachine guns;. Their difference is that when washing they form very few foam since plentiful foam can damage the washing machine. And for manual powders foaming not normirovano, moreover, is considered that the foam, the better is higher and stabler.

of Bioporoshki are Very effective

for washing in cold water biopowders. Except that they effectively wash the general pollution, their main specialization - removal of pollution of a proteinaceous origin: blood, milk, eggs, sauces, ice cream, grass. They cope and with starched, fatty and oil spots.

Certainly, for each type of washing it is necessary to observe a dosage of powder and temperature condition of washing.

So, enzymes cease to work at a temperature over 40 degrees.

Heating of water to 90 degrees is effective when washing the linen polluted by fat. Proteinaceous pollution are ready as egg and are fixed on fabric forever. Besides, at high temperature of washing, the color linen can fade

Bleaches

optical bleach is a part practically of each powder. But he does not bleach fabric, and only creates illusion of a whiteness. Parts of optical bleach which are luminescent dyes settle on fabric and allocate ultraviolet rays from a range of the falling sunlight, turning them into the seen blue, blue, violet colors. It also provides effect of a whiteness.

Photobleach which bleaches when drying on light also is a part of laundry detergents.

The real bleaching is reached at the expense of the powder of chemical (oxygencontaining) bleach which is a part. Effectively it works at a temperature of 60 degrees Celsius because such temperature is necessary for release of active oxygen - the working chemical agent. In order that the powder containing chemical bleach could work also at lower temperatures, enter the activator into its structure that allows to reach it is necessary effect at a temperature of 20 - 40 degrees.

Various supportive applications are applied to the best results of washing, except laundry detergents: gels, stain removers, bleaches, conditioners, water softeners etc.
