Usual dirt
Products of ability to live of the person: potovye allocation, the rests of the peeled skin, a bacterium. They form on fabrics insoluble in water an oil film which absorbs the painted particles of a dust.
Food pollution
Arise at preparation and at food absorption. Their nature is various, as well as our food: oils and fats, starch and kletchatka, fiber, dyes. Often pollution have the mixed character (that drink pour).
Pollution from environment
It is everything that round us: a dust of any origin, soot and products of combustion of automobile fuel, an atmospheric precipitation, a road dirt, greens, flower pollen, a grass – all that leaves stains.

Basis of washing action of a powder are surface-active substances (PEAHENS). They contact particles of pollution on a fabric and translate them in a solution. Their action is strengthened by additives which interfere with repeated sedimentation of a dirt on a fabric, eliminate rigidity of water, soften fabrics after washing.
Often simple powders not completely cope with difficultly deduced stains.
For removal of stains from tea, coffee, vegetables and berries are necessary bleaching substances.
For removal of stains from chocolate, sauces, lipstick, blood, an egg yolk high quality detergent powders contain biologically-active substances – enzimy.

At a detergent powder choice it is not bad to consider presence in a family of children. Children, as a rule, more than adults spoil clothes and not always can explain the nature of an origin of stains. Upward Certainly, at a detergent powder choice it is necessary to distinguish a washing kind: manual or in the washing machine. For automatic washing machines powders "automatic machines" are issued. Their difference that at washing they form not enough foam since plentiful foam can spoil the washing machine. And for manual powders foaming not normirovano, moreover, is considered that the above and more stably foam, the better.
Biopowders
Biopowders are rather effective for washing in cold water. Besides, that they it is effective otstiryvajut the general pollution, their basic specialisation – removal of pollution of an albuminous origin: blood, milk, eggs, sauces, ice-cream, a grass. They consult and with starched, fatty and oil stains.Certainly, for each kind of washing it is necessary to observe a dosage of a powder and a temperature mode of washing.
So, enzimy cease to operate at temperature above 40 degrees.
Heating of water to 90 degrees effectively at washing of the linen polluted by fat. Albuminous pollution are made as egg and fixed on a fabric for ever. Besides, at high temperature of washing, the colour linen can fade

Bleaches
The structure of almost each powder includes an optical bleach. But it does not bleach a fabric, and only creates whiteness illusion. Parts of an optical bleach which are luminescent dyes, settle on a fabric and allocate ultra-violet beams from a spectrum of a falling sunlight, transforming them into visible dark blue, blue, violet colours. It also provides effect of a whiteness.The structure of detergent powders includes also a photobleach which bleaches at drying on light.
The present bleaching is reached at the expense of a part powder chemical (kislorodosoderzhashchego) a bleach. Effectively it works at temperature of 60 degrees of Celsius because such temperature is necessary for allocation of active oxygen - the working chemical agent. That the powder containing a chemical bleach, could work and at lower temperatures, into its structure enter the activator that allows to reach it is necessary effect at temperature of 20-40 degrees.
