The use of cationic surfactants allows you to remove even the so-called "traffic film" (film traffic) - a thin layer of impurities of different nature directly on the paint surface of the car. Thus, this technical solution enables contactless sink of high quality and with minimum cost in time in the face of serious pollution in the autumn-winter period.

The invention includes hydroxides of alkali metals, complexing agents, cationic surfactants, nonionic surfactants of different nature, nizkokaloriynye alcohols, hydrotropic. All these components are essential to obtain high-quality foam, high solubilities ability, wetting and, consequently, an excellent washing ability.

Thus, the presence of salts oksietilidendifosfonovaya acid (OEDF) and salt ethylendiaminetetraacetic (EDTA) acids play a key role in the binding of hardness salts (ions of CA2+, Mg2+, Zn2+Fe3+, Ni3+etc.). And salt OEDF more work on the binding of trivalent cations and divalent salt of EDTA. Also solidto prevent the formation of polymer side products HEDP salts of bivalent metals, to avoid draught in the breeding of the product and store the solution in a few days. Sodium citrate and sodium silicate perform similar function and can produce a synergistic effect with other complexions.

Alkylpolyglycoside or alkylated derivatives of β-alanine of the General formula RR'NCH2COONa are good hydrotropism and allow to alter the colloidal properties of foods, namely to increase the solubility of hydrophobic components in water.

Cationic surfactants provide the foam with a "sticky" properties, which gives extreme hold on the surface and good wettability.
