Abstract

Household hygiene cleaning powder, especially for removing salt deposits from sanitary ceramics, tiles, glass containers and the like, contains a crystalline salt of inorganic acid, an organic acid, a surfactant, optionally a perfume additive and a zeolite-based additive of 35-50%. % by weight. The additive contains 40 to 80% by weight of cloptiltilite in acid form and the remainder of clinoptilolite is in natural form, with at least one form of clinoptilolite being dehydrated.

Description

The invention relates to a composition of an acid-reactive household hygiene cleaning composition which excels in increased efficiency while at the same time reducing the hygienic and ecological risks during its application. These properties are the result of the use of a combination of clinoptilolite-based additives.

For the cleaning of household ceramics (washbasins, bathtubs, tiles and special toilet bowls), kitchen utensils (enamelled and glass), tiles, etc., usually from calcium deposits and incrustations, mostly strong aggressive, acid-reactive agents are currently used. Liquid preparations are usually based on phosphoric or formic acid. Their effectiveness is usually accompanied by a negative ecological effect (especially for preparations based on phosphoric acid and its derivatives) as well as a significant hygienic risk (possibility of skin burns). Loose cleaning compositions usually formulated on the basis of crystalline amidosulfuric acid or on the basis of acid salts of inorganic acids have similar adverse side effects. They are usually combined with an abrasive component, which is usually chemically inert under the given conditions, they also contain a suitable surfactant, perfume or other additives. The disadvantage of such compositions is, in addition to the high cost of the active ingredient, also some processing and user properties (for example, the tendency to sintering), but especially the unsuitable ecological effect manifested in the watercourse. It is manifested by the dissolution of deposits and sludge, with the remobilization of the components contained in them (for example heavy metals), multiplied by the presence of complexing components or polyphosphates.

The invention relates to an acidic cleaning composition based on a crystalline salt of an inorganic acid, a crystalline organic acid, a surfactant and aromatic additives, characterized in that it contains 35 to 50% by weight of clinoptilolite-based additives, of which 40 to 80% by weight is clinoptilolite in acid form and the remaining clinoptilolite is in its natural form, with at least one form of clinoptilolite being dehydrated.

By using this combination, several positive effects are achieved at the same time. In the first place, the dehydrated zeolite counteracts the tendency of the usually crystalline acid-reactive components of the mixture to form undesired agglomerates during manufacture or storage. The dehydrating ability of the zeolite also reduces the risk of skin burns on contact with the product. Conversely, rehydration of the zeolite during application releases heat, thereby increasing the temperature of the reagent and the speed of the purification process.

After wetting the formulation with water during application, the acid form of clinoptilolite reacts with the cations in the system of salts present to form the corresponding acids as highly effective components attacking the removed deposits. At the same time, the acid form of the zeolite softens the water, allowing it to be used in the composition! smaller amounts of surfactant. At the same time, zaol acts as an abrasive agent, while due to the relatively low hardness of the particles, it does not mechanically damage the surface of the cleaned objects.

A significant benefit of the use of natural or acidified clinoptilolite is its ecological behavior in a watercourse after rinsing the cleaned object with water. The result of their high affinity for heavy metals is their immobilization in the structural lattice of zeolite, which prevents the penetration of these hygienically hazardous components into the lower lines, plants and higher stages of the food chain.

To achieve other desirable effects, said components of the described mixture can be combined with the components increasing the cleaning effect, perfumed them, or supplemented with a disinfectant.

By acid form of clinoptilolite is meant clinoptilolite in which exchangeable cations (usually alkali metals and alkaline earth metals) are replaced by a hydrogen cation.

By dehydrated form of clinoptilolite is meant clinoptilolite free of water originally bound in the crystal lattice by annealing.

Example 1

Composition of the product:

- acid form of clinoptilolite ........................... 200g

- natural clinoptilolite dehydrated ................. 250g

- bulk surfactant (see note) ........................ 3g

- crystalline acidic sodium sulphate ........................ 450g

- crystalline oxalic acid ......................... 95g

- perfume ............................................... 2g (Note: supported rapeseed oil oxyethanolamide)

Example 2

Composition of the product:

- acid form of clinoptilolite dehydrated ............. 350g

- natural clinoptilolite ............................... 100g

- bulk surfactant (as in Example 1) ...................... 5g

- crystalline acidic sodium sulphate ........................ 500g

- crystalline oxalic acid ........................... 45 g

Both mixtures described in the examples showed higher effects in testing than comparable preparations used hitherto, without containing undesirable components from the ecological point of view (e.g. phosphoric acid derivatives), nor from a hygienic point of view causing adverse reactions (e.g. skin corrosion in case of accidental short-term contact).
