The aqueous alkaline liquid cleaners of the present invention are compositions of relatively high viscosity, which may also contain oxidizing agents or may be diluted with solutions having an oxidizing effect. They can be used well in households, industry, agriculture and infrastructure. In addition to their cleaning effect, compositions containing oxidants also have an excellent disinfectant effect and are therefore advantageously used, for example, in slaughterhouses and hospitals. Due to their relatively high viscosity they are suitable for cleaning vertical surfaces.

Alkaline liquid detergents are known to have good liposuction properties due to their solubilizing properties. To increase the viscosity of such alkaline surfactant solutions, macromolecular structures, generally cellulose derivatives, are used (see Éva Juhász et al., Surface Pocket Book, p. 252, 1979). It is also known that alkaline solutions having an oxidizing effect, mainly containing active chlorine, are widely used for disinfection. The activity of these disinfectants is greatly reduced during storage. Over a three-month period, a 5 to 10% reduction in the active chlorine content is expected compared to the amount initially present.

There is a need for liquid compositions of relatively high viscosity which, in addition to their lipid solubility, also have a disinfectant effect. Polymers in the known alkaline, relatively high viscosity detergents are rapidly degraded by oxidizing agents (e.g., sodium or potassium hypochlorite) used for disinfection, so that they cannot be mixed with oxidizing solutions without significantly reducing their viscosity.

It is an object of the present invention to provide liquid cleaners of alkaline, relatively high viscosity and stability, which may contain oxidants or may be diluted with compositions containing oxidants without deterioration in quality.

The present invention is based on the discovery that in alkaline media, association processes similar to liquid crystal formation can be induced between certain types of surfactant molecules. The intense interaction between the surfactant molecules can be facilitated by the formation of large, so-called mixed micelles, with trialkylamine oxides known as pseudo-surfactants having cationic properties. Examination of various surfactants has shown that anionic sarcosinates and / or secondary alkanesulfonates interact strongly with trialkylamine oxides in an alkaline medium. Due to the strong association, relatively high viscosity solutions with reduced surface tension and thus good washing performance and grease removal ability are made without the use of viscosity enhancing polymers. The high mass surfactant micelles in the compositions of the present invention are resistant to oxidation, so such cleansers may also contain oxidizing agents or dilute them with oxidizing solutions. In formulations containing active chlorine, the amount of active chlorine is reduced by up to 5% over a three-month period.

The alkaline aqueous liquid cleaners of the present invention contain from 10 to 150 g / l, preferably from 20 to 50 g / l, of alkali metal hydroxide and from 10 to 200 g / l, preferably 60 to 120 g / l, relative to one another. : 1) to 1: 5, preferably 5: 1 to 1: 3, by weight, of trialkylamine oxide of formula I and one or more of the sarcosinates of formula II and / or secondary alkanesulfonate

- in which formulas

R ¹ and R ^{2 are} methyl,

R ^{3 is} C 10 -C 18 alkyl,

R ^{4 is} C ⁵ -C 21 alkyl, C 15 -C 17 alkenyl, or alkedienyl,

R ⁵ and R 0 are C 1 -C 16 alkyl,

They contain ammonium ion substituted with M ⁺ alkali metal or C 1-8 alkyl or hydroxyalkyl groups, optionally accompanied by perfume and / or coloring and / or oxidizing agent.

Preferred embodiments of the cleaning agents of the present invention are dimethyl laurylamine oxide or C 14 or C 16 alkyldimethylamine oxide and sodium lauroyl sarcosinate (tradename Medialan LD) or sodium or triethanolammonium coconut fatty acid sarcosinate. or triethanolammonium sunflower fatty acid sarcosinate and / or C 15 sodium secondary alkanesulfonate and / or C 14-16 triethylammonium secondary alkanesulfonate.

Optionally, compounds containing active chlorine as oxidizing agents of the compositions, e.g. They may also contain potassium or sodium hypochlorite, preferably a perfume, e.g. "Hypofresch" perfume and / or colorant, e.g. potassium permanganate or potassium bichromate.

The detergents of the present invention have the advantage of providing new, pseudoplastic, good foaming and excellent lipolytic compositions to the currently known alkaline liquid detergents, which, due to their relatively high viscosity, are also useful for cleaning vertical surfaces. The formulations offer the possibility of combining the detergent with the disinfectant action by containing oxidizing agents or diluting them with solutions containing oxidizing agents without the risk of deterioration. In formulations containing active chlorine as an oxidizing agent (e.g., in the form of sodium hypochlorite), the reduction in the active chlorine content is less than that seen in prior art agents. The cleaning agents of the present invention are illustrated by the following example, without limiting the scope of the invention to the compositions thereof.

Example

Eighteen types (A-R) of alkaline (pH> 13) compositions were prepared according to the compositions given in Table I, and their viscosity and the amount of active chlorine in the compositions containing the oxidant were determined over time.
