Description

The present invention relates to the production of enzymatic detergent compositions and provides solutions for their high efficiency at economically viable enzyme contents.

Most detergents of advanced manufacturers include enzymes, especially alkaline proteases or even amylases. Powder form of detergents is almost twenty years old, for liquid products this is a recent issue.

Due to the high environmental sensitivity of enzymes, the application of enzymes, as one of the most expensive parts of detergent formulations, accounting for 10% or more of the total raw material cost, is associated with difficulties and constraints on composition. In addition to the known effects of pH, many of the common and most commonly used detergent raw materials have an adverse effect on the enzyme upon storage and cause its partial denaturadiation in the wash solution. Negative effects of, for example, alkylbenzene sulfonates are reported, and, on the other hand, favorable effects of, for example, alkyl polyglycol ether sulfates. Therefore, the composition of enzymatic detergents is given great attention. A variety of stabilizing agents are applied, such as borax, calcium chloride, formates, and a number of other agents, or raw materials with an activating effect such as ethanolamine salts of anionic surfactants and complexing agents.

Another modern trend in the detergent sector is the production of softening by-products. These products are in many ways able to replace additionally applied classic fabric softeners. In addition to anionic and nonionic surfactants, the active ingredients in the formulations of these detergents are ampholytic or selected cationic types. Preferred in this respect is the use of alkylalkoxylated quaternary ammonium salts, which are also known as raw materials with good wool fiber action.

The detergent according to the invention has the desirable properties of a detergent composition with an increased enzymatic activity consisting of surfactants, biologically active, fillers, special or even complexing additives, characterized in that it contains 0.5 to 5% by weight of a mixture of alkylaxylated quaternary ammonium salts formulas:

I _(CH2 - _CH2 - 0) H CH ₃ to ₄ wherein R is a Cg to C ₂₂ and n + m = 3-9, and alkaline proteases at a weight ratio of components of 1: 0.5 to 3, when said contents of alkaline proteases are counted at an activity of 300,000 Dj / g, 5 to 50 wt. % of other surfactants, 0.3 to 60 wt. 2 to 60 wt. % of fillers and 0.001 to 60 wt. special additives.

Other types of surfactants are alkylbenzene sulfonates or alkyl sulfates or 6-olefin sulfonates or alkanesulfonates or alkyl polyglycol ether sulfates or alkyl esters of phosphoric acid or soaps or alkylamides of ethylenediaminetetraacetic acid or alkylamidobetaines or oxyethylated or oxypropylenated oxyethylene fatty alcohol or optionally / five-component mixtures thereof, the anionic surfactants being in the form of sodium or potassium or mono to triethanolamine salts.

The binders used are triphosphate or pyrophosphate or nitrilotriacetate or ethylenediaminetetraacetate or a polymer, optionally a copolymer of acrylates or derivatives of methylene phosphonate or a citrate or aluminosilicate or two- to four-component mixtures of said substances, when the binders are sodium or potassium or mono-tri- or mono-tri-salts.

Fillers are water or ethanol or sodium sulfate or a two- to three-component mixture of these raw materials.

Special additives means sodium carbonate or bicarbonate or sodium silicates with different SiO ₂ modules: Na ₂ O or cellulose derivatives or perfumes or stabilizers of perfume based on silicon dioxide or polymeric organic compounds or optically brightening agents or sodium tetraborate or sodium perborate or perborate activator a base of acetylated organic compounds or magnesium silicate or enzymes or antifoams based on silicone or polypropylene oils or propylene glycol or glycerin or a colorant or a two to ten-component mixture of said additives.

The main advantages are the possibility of improving the economy of production of enzymatic detergents.

Formulations with high enzymatic efficacy are prepared by a conventional method of making powdered or liquid detergents. Exemplary compositions include the following recipes (in% by weight).
