The invention relates to household chemicals and, in particular, to a molded composition of the solid detergent for cleaning hard surfaces or fabrics and, more specifically, compositions of the invention are suitable for hand washing.

The level of technology

The detergent composition for cleaning fabrics and hard surfaces typically include surfactants, which are designed to facilitate the removal of contaminants. Mainly the system of surfactants are chosen not from the group of Soaps. In addition, it is expedient to introduce into the composition of various abrasive particles, fillers, modifying additives and other components such as colorants, fragrances, preservatives, etc.

Cleansing compositions in solid form is much cheaper than in the liquid, due to the low cost of the packaging, and these forms are very popular in developing countries. Among the solid forms of the bars are becoming increasingly popular on the market of developing countries due to convenient use. Facilitated the dosage of the product in solid form, are eliminated losses from leakage and can better control the application of the product. Cleansing compositions in the form of bars is much more economically feasible than other forms of the product, and is easily controlled dosing of the bar when manipulat is I. For detergent bars required acceptable physical strength, in order to maintain structural integrity during manipulation, transportation and application. However, detergent bars for cleaning fabrics and hard surfaces are in constant contact with water during use and subsequent storage and therefore become saturated with moisture and is usually destroyed and take the form of a paste. The shape and contours of the bar are poor.

Usually this problem is solved by making appropriate changes in the formula bar. Any attempt curing of the bar, if it is not controlled properly in the formulation, may lead to the hard product, which will not stand out enough product for satisfactory cleaning. Therefore, the main problem is to ensure that no grinding of the product in use and product loss by the formation of a mushy mass and at the same time, the product was soft enough that the consumer had the opportunity to find the right amount of product to clean.

In the patent IN India 166806 describes a method for detergent bars having good strength and technological properties during transportation and use by the in troduction the help of various dehumidifiers during neutralization.

In the application WO 9518215 (company Ecolab Inc., 1995) revealed detergent stable in the environment. Absorbent cleaning material is resistant to water absorption or moisture from the environment by introducing a barrier coating on the surface of the detergent. The aim of the invention is the production of concentrated aqueous detergent for use in washing machines, and control of excessive dosing. This hydrophobic coating to crack, split or peel off, or partially removed, to ensure the dissolution or melting of the coating orderly manner.

In the application WO 9955823 (company Procter and gamble, 1999) revealed no powdered detergent product, which has a core formed by compressing powdered material, which includes a detergent surfactant and modifier additive having a practically water-insoluble coating which substantially covers the contour of the core, in order to provide mechanical strength, resistance to shock and spalling of compressed tablets. In addition, it is essential that the coating dissolves in the alkaline environment or easily emulsify under the action of surface-active substances.

For illustration of the invention used washing composition used for washing dishes and having the composition specified in table 1. The bar compositions not covered by any waterproof material (example 1), as in example 2, the bar is covered with a film having a thickness of 40 μm and made of the copolymer of Methacrylonitrile (50/50)that has a coefficient of permeability greater than 1·10-10[cm3][cm]/[cm2][C][PA], more preferred values for the present invention. In examples 3-5 in the composition of the film is a mixture containing 25 wt.% amorphous poly-alpha-olefin and 75 wt.% microcrystalline waxes are melted together at a temperature of 150°and have a permeability less than 1·10-13[cm3][cm]/[cm2][C][PA], which corresponds to the present invention. The film thickness is less than 5 μm (example 3), more than 1000 μm (example 4), and is equal to 40 μm (example 5). In examples 2-5 bars were coated with a membrane on all sides except the surface, which is used in the operation of the product.

Determining the integrity of the bar

The bars corresponding to examples 1-5, tested by experienced experts in one week when washing dishes under controlled conditions simulating the operation of the consumer. Experts estimate the bars on a scale from 0 to 10, where 0 means very little to crushing and deformation, and a score of 10 corresponds to a very considerable crushing and deformation. Similarly, the experts assess the bars on a scale from 0 to 10, where 0 corresponds to very high efficiency and 10 very low efficiency when used.

In addition, experience bars by immersing parts thereof covered with a film of water for two hours, and after 2 h determine the weight loss of the bar due to dissolution. These data are shown in table 2.

In the drawing, a-C, shows the appearance of the bars before and after use, where

* Coating is too thick to wear off, which leads to high efficiency.

Bars, according to the invention, are cost-effective because the loss of weight of the bar due to the dissolution is very low, which is confirmed as the experience is imentally data and assessment experts. The control bars and bars with a film thinner than 5 μm, become highly deformed, and when the film thickness exceeds 1000 μm, the film wears away during use and remains a shell. This also leads to high efficiency, but it is undesirable for the consumer because of the inconvenience of the selection of the product and for aesthetic reasons.

A coating of microcrystalline wax

The bars are produced by extrusion of the formulation of detergent compositions specified in table 1. Bars cover with hot melt covering songs by mikania bar for 3-5 seconds in a bath containing the composition at a temperature of 150°C. the Excess coating material is allowed to drain into the tub and cool covered bar to room temperature. For more information about the composition of the covering material are shown in table 3.

Various properties of the bars determined using the following methods.

1. The adhesion of the coating. The adhesion of the coating is measured by evaluating the ease with which film coating is removed from the surface of the cleansing block. Estimates vary from 1 to 5. A score of 1 indicates an excellent coating adhesion on the surface of the bar, while a rating of 5 corresponds to a weak adhesion, and the coated film is easily removed from the surface of the bar.

2. The integrity of the bar. The integrity of the br is ska appreciate the technique, described earlier.

The data in table 4 demonstrate that the detergent bar, having on the outer surface of microcrystalline wax, alone or in combination with polyolefins, excellent adhesion of the coating and, in addition, preserves the integrity of the bar.
