Cleaning compositions

Pathetic compositions

Field ^tThis invention relates to aqueous purification compositions which comprise low levels of surface-active amino acids and exhibit a characteristic shear-reduction shear behavior, i.e., very high viscosity ratios. * This type of behavior is particularly useful in cleaning compositions intended to be applied as non-horizontal surfaces such as burner walls.

-2. -I '' '- * ./L and sanitary equipment such as sinks, showers, wash basins and toilet basins. * The invention relates to specific aqueous cleaning compositions containing hypochlorite bleaching agents commonly used on the surface of sanitary equipment.

It is known that the greater the viscosity of the liquid composition, the longer the residence time will be when applied to a non-horizontal surface such as a wall, viscosities can be increased by many times, e.g. by using a polymeric organic viscosity enhancer as a component of the composition, by increasing the content of dissolved components, by adding solid components, suspended in solution or by modifying the characteristic properties, the.

Each of these methods has the limitations of the viscous polymer increasing viscosity, even if they are valuable in compositions that do not expose themselves to a corrosive aqueous environment, which are useful where either the composition contains aqueous chloride. projected the polymer, thereby destroying the viscosity of the latter. Simple increases in the content of the ingredients in the solution have a limited effect on the viscosity of the solution and thus are not particularly ineffective: proportionate to their cost. The addition of solid, i.e. The non-soluble constituent entails additional complications as it should avoid the precipitation or formation of sediment in the self-storage or physical form of the product normally enclosed; Modification of natural hazards

-3-wt% of dissolved constituents by interacting with viscosity-forming phases can also create limitations on the type and content of the constituent.

To overcome the problem of viscosity (and bleaching) stability, increased viscous aqueous compositions containing hypochlorite have proposed a number of compositions. Further, it comprises superficial active combinations of substances which are stable in a hypochlorite diel such as e.g. compositions disclosed in BP I529O86 and BP I4I6767, in all European patent applications published. 2,558 and 50401 and the French patent under. 2555909 · Leukautic hypochlorite compositions containing surfactant combinations of surfactants with a product viscosity values ​​of up to "150 l'Pa. Secondly, by announcing the technique otherwise, the achievement of higher viscosity will not be particularly diminished, and it is believed that essential surfactant rates are likely to appear to be economically attractive.

It has now been found that long-chain aqueous amino acid solutions in combination with certain aromatic compounds having a carboxylic or hydroxylic functional group and having a definite amphiphilic character are capable of characteristic behavior. This results in very large viscosities with small shear ratios, which is produced by the movement of the liquid down to a viscous surface having its own weight, resulting in a small viscous fluid. the neck of the bottle with a flexible wall.
