Abstract

The composition allows for intensive circulation automatic machine washing with the agent quality parameters not yet achieved in terms of wettability stability and disoergic abilities. Washing supports reduced surface tension of the washing solution Taking a surfactant that couldn't be applied before. The other ingredients are specifically active ingredients, activators and stabilizers foam

Description

The present invention provides a liquid detergent composition with a chelating surfactant. It is designed for mechanical mechanical washing and cleaning of food equipment packaging and dishes while reducing human labor,

The detergent is based on the application possibilities and synergistic effect of a chelating surfactant based on monoethanolamidethylenediaminetetraacetic acid with six to twenty carbons in alkyl in a solution of electrolytes and chelating agents,

At present, strongly alkaline chemicals are added individually to the washing baths for washing food equipment for dishes and bottles, or in electrolyte mixture concentrates. Bottles in breweries are traditionally washed with sodium hydroxide. Automatic dishwasher detergents contain electrolytes such as alkali hydroxides, sodium metasilicate, potassium pyrophosphate, all in the maximum concentrated solution sometimes with the addition of sodium hypochlorite. These preparations may also contain chelating agents in the form of chelaton, but in these cases hypochlorite cannot be applied. So far, it has not been possible to apply the required amount of surfactants to the product without their salting out due to the electrolyte. Existing automatic machine washing detergents are therefore free of wetting agent. According to our procedure, the surfactant can also be applied to a concentrated solution of sodium nitrilotrioacetate, sodium salt, ethylenediamine monotetraacetic acid, alkali hydroxides, soluble polymeric phosphates, silicates and carbonates. Thus, it is possible to assemble mainly products which are diluted to the required concentrations during application and can be supplemented with other effects during the preparation of solutions, such as disinfection, foam control by means of silicones, soap or nonionic surfactants.

The above condition improves and specifies the invention of a liquid detergent composition with a chelating surfactant comprising monoalkylamidethylenediaminetetraacetic acid trisodium salt of six to twenty carbons in alkyl, which is a surfactant with chelating potential and ability to solubilize with other specifically active ingredients, activators, foam stabilizers. disinfectants, dyes, biologically active substances, fragrances and fillers.

Its essence lies in the fact that it contains in% by weight. 1 to 40% of substances from the group of organic chelates such as sodium nitryltrioacetate, 1 to 40% of ethylenediaminetetraacetate, 1 to 30% of alkali metal hydroxide, 2 to 40% of polymeric phosphates, 3 to 15%; alkali silicates and 0.5 to 20% of ethylenediaminetetraacetic acid monoalkyloamide trisodium salt with 6 to 20 carbons in the alkyl.

An advantage of the present invention is the possibility of applying a surfactant with a wetting and chelating effect in a relatively concentrated solution of electrolytes as active detergent components. When used, the products prevent the formation of limescale and remove older deposits.
