OF THE INVENTION PROCHÁZKA KAREL, LOPATA VÁCLAV ing., RAKOVNÍK, TOLMAN JIŘÍ,

ROZTOKY, NOVÁK JAN Ing. The present invention provides a detergent composition with enhanced efficiency for washing, laundering, washing, rinsing of solid and porous surfaces, comprising surfactants, activating, softening, filling, dyeing, and detergent compositions. disinfectants, biologically active, fragrance and other ingredients or mixtures thereof.

One of the essential ingredients of a detergent is a group of substances labeled with the name of the activation primer. Their basic function is the ability of the binding ions, especially calcium and magnesium, to water-soluble compounds, allowing good detergent efficacy at low surfactants. Among the most widely used types of activators are condensed phosphates, of which especially the polyphosphate meets all the technical requirements for activating additives. However, the need for increased environmental concern has caused phosphates to become an undesirable raw material for detergent production due to eutrophic water surfaces. One of its main causes is phosphorus, and the proportion of phosphorus from laundry detergents is one of the most important, easiest to control and capable of limiting. Therefore, other types of activators, such as polyelectrolytes, aluminosilicates, organic complexes, citric acid and others, are increasingly used in detergent production. All three known raw materials for tripolyphosphate do not reach its efficacy even though they suit eutrophication. Some of these activating additives, such as citric acid and nitrilotriacetic acid, have some other advantages over polyphosphates, for example, their improved usability for manufactured compositions, where they do not have the distinct surfactant effect. However, their use in liquid formulations is also accompanied by a more effective activity against tripolyphosphate.

Also, citric acid and nitrile acetic acid provide enhanced detergency-containing detergents with detergent compositions for washing, washing, rinsing, rinsing solid and porous surfaces, composed of surfactants, activators, softeners, fillers, dyes, disinfectants, biologically active ones. flavorings and other additives, or mixtures thereof, comprising from about 7% to about 70%, preferably from about 10% to about 35%, of a mixture of citric acid and nitrilotriacetic acid in a weight ratio of from 1.5 to 20: 1, preferably from 2.5 to 6: 1, wherein both acids may be in the form of mono- to tri-sodium, potassium, ammonium or mono- to triethanolamine salts, or mixtures thereof.

The enhanced performance of the detergents of the present invention is best demonstrated by the following table showing the detergency of detergents on a polyester / cotton blend fabric at 50 ° C determined by the methodology used by State Testing Laboratory No. 240. 196695
