The technical field to which the invention relates.

The invention relates to compositions cleaners synergistic effect which contains surfactants and swelling polymers that are suitable for cleaning hard surfaces.

The level of technology

Industrial detergent composition for cleaning hard surfaces typically include one or more surfactants and dispersed in many of them the abrasive particles. The combination of surface-active substances, together with electrolytes, often used for suspendida system for abrasive additives that are well known in the art. Offers a variety of compositions of detergents in the form of liquids, pastes, gels, powders and solid bars. Typical abrasive materials used in these compositions include calcite and dolomite.

Solid surfaces in household appliances are kitchen utensils and accessories, walls and floors in kitchens, work surfaces and sinks, walls, floors and plumbing bathrooms and toilets, and floors of other buildings, etc. which are formed of various kinds of pollution. Pollution commonly found in the upper parts of stoves and utensils are of two types, namely easily removed or oily dirt and labour is but remove dirt, consisting of dried and stubborn food. The problem of removing these contaminants becomes more acute when you want to make significant efforts to clean items from this solid dirt that has accumulated over time.

Usually the proportion of surfactants in detergent compositions has a value up to about 20%, and the rest is other ingredients. An important part of the recipe are abrasive materials, builders and fillers. These ingredients must be added to improve the effective flowing property surfactants for cleaning surfaces, particularly if washing manually.

In cleansing compositions using polymers to achieve a variety of useful purposes, such as outlining features and remove the dirt. In document EP 883670 (Unilever, 1998) discloses high viscosity of the gel composition for washing dishes. They have a two-component structural system containing 0.2-2% cross-linked polycarboxylate and azole.

Adding large amounts of water, along with abrasive materials, detergents components of detergent and fillers, increases the volume of the product and, therefore, increases the cost and difficulty of transporting the products from the place of manufacture to the place of its consumption.

Thus, there is a need in anantanubandhi cleansing compositions which can turn a consumer into usable product by adding water. This concentrated composition saves on transportation costs and packaging of the product in comparison with the diluted composition.

Brief description of the invention

The present invention provides a concentrated cleansing composition a synergistic effect which contains one or more surfactants and one or more swelling in water of the polymers that can absorb water in an amount greater than their own weight. This song can be turned into a chunky paste or thick liquid by adding water before use to ensure the flowability of the composition according to numerous surfaces to be cleaned.

Detailed description

All these are percentage and proportional relationships are given by weight of the composition, unless otherwise indicated.

Thus, the present invention provides a concentrated cleansing composition synergistic effects contains

(a) 5-95% of one or more surfactants,

b) 5 to 95% of one or more swelling in water of the polymers which absorb water in excess of their own weight.

In the context of this is subramania the expression "cleaning composition" refers to compositions in the form of solid powders, tablets, pellets or noodles, or in the form of a paste or gel, which can be turned into a product with increased volume by adding water. Thus obtained product can more easily be applied or spread over the surface to be cleaned.

Alternatively, the abrasive material may be to some extent soluble, and it is present in such excess with respect to the water present in the composition, when mixed with water before use, in order to improve the solubility of the abrasive material in the aqueous phase, and as a result, this abrasive material náchod is conducted in the solid phase in the swelled mixture.

The swelling ability of the polymers to form a gel or paste may be reduced in the presence of certain electrolytes. For example, in the presence of calcium ions decreases the ability to swell crosslinked polyacrylic acid, which is a swelling in water of the polymer. Therefore, you need to carefully choose the abrasive inorganic particles, excluding the above substances. If their presence is absolutely necessary, they should be used in minimal quantities.

Suitable abrasive materials can be selected from the following substances: particles of zeolites, calcite, dolomite, feldspar, silica, silicates, other carbonates, oxides of aluminum, bicarbonates, borates, sulfates, and polymeric materials such as polyethylene.

b) 10-90 wt.% inorganic particles and other conventional components.

Hereinafter the invention will be illustrated in the following examples, without limiting its scope.

Examples

1. The influence of the interaction of the polymer with a surface-active agent on the formation of a gel

The compositions shown in table 1, obtained by mixing a surfactant and a polymer. The resulting product is a powdery mass. In each of these products add 50 g of water and allow to stand for 1-2 minutes. Table 1 lists also the appearance of the products after the addition of water and the volume of the resulting gel.

The measurement of the volume of gel (ml) after the addition of excess water

Pastes the shaped/thick liquid, formed in examples 1-6 above, is transferred into a separate graduated measuring cylinders with a capacity of 250 ml and bring the liquid volume to 250 ml by adding water. The contents of the cylinder mix for one minute, then allow to settle in for the night and explore. The contents of the cylinder is divided into two phases (in examples 1, 2, 3 and 6). The gel formed under the effect of swelling the polymer, is deposited on the bottom, while the water layer remains at the top, and measure the volume of the gel layer. The volume of the gels (in the presence of excess water) characterizes the gelling ability of swelling of the polymer in the presence of surfactants. It is assumed that the greater the volume of the gel, the less the negative impact of surfactants on the swelling polymer.

The data in table 1 show that the polymer is an essential component in the formation of the gel, and in the presence of nonionic surfactants polymer forms a good solid, gel-like. From this it follows that the choice of surfactants is important to determine the strength of the gel and its volume, which, in turn, determines the consistency of the resulting paste.

2. Influence of the nature of surfactants on the formation of a gel

To determine the effect of the nature of the surface is Resto-active substances on the formation of gel explore anionic and nonionic surfactants, taken in different ratios in compositions shown in table 2. The product is mixed with water and explore the nature of the gel. The measurement of the volume of gel (ml) after adding an excess of water is performed by the method described above. In addition, evaluate performance by considering the efficiency of treatment.

Measurement of cleaning efficiency

Take 1 g of the gel formed by adding 100 g of water to 7.5 g of powder in a single dose, using fixtures, and clean the dirty plate. During the cleanup define the various cleanup options and consumer properties. Based on the overall feasibility of the cleaning performance is evaluated on a scale from 1 to 5, where 1 refers to the 'poor' and 5 is 'good' performance.

The data in table 2 show that the polymer is an essential component for receiving lubricating gel, but has poor performance when cleaning (example 9). When the composition is present only surfactant without polymer, the gel is not formed, and the cleaning efficiency is reduced (examples 10 and 11), as the polymer contributes to the effective flowing property of the active component. Performance of compositions as in examples 7, 8, 12, and 13, with respect to the formation of gel and treatment effectiveness show that an appropriate combination of surfactant and polymer is important to obtain a composition, which has optimal cleaning efficiency and good durability of a gel.
