Stange affect any or the next 80 parts by weight of one of a mixture of uses by preventing the dissolution of 5-80% by weight of tallow fatty acid and 20% by weight of the detergent. Therefore, it is desirable that sodium soap made from coconut fatty acid, the oil removed from the skin on the bar surface can be easily rinsed off in about 1000 parts by weight of hot water and this dissolved. In the resulting solution, if the receding contact angle 20 parts by weight of neoprene rubber powder was stirred in, was more than 30 °. io whose particles in all three directions were about. In order to achieve the desired, comfortable feeling at the same time, a mean diameter of the use of the preparations according to the invention, about 30 microns and a largest diameter of the water-soluble organopolymer particles should have 100 microns and one Contact angles had a diameter, ie a minimum dimension, measured in the advancing oil phase of at least 0.1 microns, and important is about 105 ° and in the receding oil phase furthermore that it was at least 99% a maximum dimensioning about 70 ° . The dispersion obtained in this way, elongation of no more than about one millimeter, was dried, powdered and ir. With the expression tableting machine used here pressed into bars, the "finely distributed particles" thus meaning particles of moisture content according to customary methods of the. It is true that it does not depend on the exact soap- making technique that was set in the way it was in the particle shape, and one can just as well consider flat or platelet-shaped products for easy shaping and good foaming as well as thread-like or borrowed products. The finished rods were made of a laser-shaped particle as well as powdery masses with un- Group of people who had their hands soiled with a conical or spherical particle of colloidal graphite emulsion in mineral oil, desirable, but not necessary, on hand washing. Ability examined. This, however, that the particles neither have sharp edges nor the hand-washing test also nor with the same peaks and the polymer material one conditions, but using on the one hand a comparatively low flexural modulus, namely a similar but neoprene powder-free soap bar and tolchen below about 3.52 · 10 ₄ kg / cm ² in order to provide the highest level of comfort on the other hand for a rod made of commercially available mechatronics. In particular, 30 nicer soap is repeated, the 40 percent by weight anorcs is desired that each contained at least 99% of the polymeric emery. The preparation particle according to the invention on the one hand in one dimension less soap bar was measured against the particle-free than 250 microns and on the other hand preferably in two soap bars in terms of cleaning power as far dimensions each less than 125 microns. To be superior to and compared to mechanic's soap as the usable organopolymer materials are judged to be far more pleasant and scratch-free. The one made of elastomers including natural and inventive soap also showed little or more synthetic rubber, such as neoprene, butyl rubber, butt at all, after use, to retain the dirt adiene polymers, butadiene copolymers with styrene.

In the case of bars or pieces, for example, there is a group of people who gave the judgment good, acceptable or allowed the weight ratio% of polymer particles to watery. The contact angle measurement was carried out in the free detergent, especially if the latter was made from the advancing oil phase. Which exists as a powder aside, usually between 6: 4 and 1: 9. 55 particles drawn were in all three directions. In cleaning pastes for heavy-duty hands, the corresponding weight ratio, in particular 50 microns, can be of the same order of magnitude on average. Only in Example 11 was the sulfonated detergent between 9: 1 and an average of 5 microns. The maximum expansion of the 1: 9 vary. For hair and soft face wash powder particles that are exceeded by no more than one in a hundred medium in pasty or liquid form one takes for 60, the table usually has the same weight ratio as given in each case.

The specific embodiments described above are by no means intended to be the only ones possible to be considered the invention; Rather, this is intended to include all modifications and amendments which are familiar to the person skilled in the art within the meaning and scope of the following claims.

Experiments are given below which demonstrate the surprisingly good effect of the skin cleansing preparations show according to the invention.

One test person soiled their hands with a standard dispersion of graphite and oil and Then washed the dirty hands with water and one of the following skin cleansing products:

Example 15

A shampoo preparation was mixed together according to the following recipe:

1. Toilet soap with 5 percent by weight neoprene particles with a particle size of less than 0.17 mm;

2. toilet soap according to 1 without neoprene particles;

3. 0.15 g of neoprene particles with a particle size of less than 0.17 mm;

4. 0.15 g of neoprene particles according to 3, subsequent rinsing with water and finally washing with the toilet soap according to FIG. 2;

Toilet soap according to FIG. 2, subsequent rinsing with water and finally washing with 0.15 g of the neoprene particles according to 3:

Skin cleansing preparations 1 and 2 were used in an amount of 3.0 g for washing. on this basis became the amount of neoprene particles used in skin cleansing preparations 3 to 4 certainly.

The test was carried out under carefully controlled conditions carried out as follows:

Stage 1: First, the hands were covered with a commercially available piece of a pumice stone Washed with soap, then with a paper towel and finally for at least 10 minutes at room temperature air dried.

Step 2: A drop of a colloidal dispersion of Graplut in oil was then placed on the palm of each hand and distributed evenly over the entire palm with the fingertips of the other hand.

Step 3: The hands and the respective skin cleansing preparation were then moistened with water and rubbed between the hands for 10 seconds.

Step 4: The fingertips (not the fingernails) of each hand were used to cleanse the skin worked into the stained areas of the palms for 10 seconds.

Step 5: The hands were then rinsed with water and left damp.

Stage 6: Stage 3 was repeated.

Stage 7: Stage 4 was repeated.

Step 8: The hands were rinsed with water and dried.

The effectiveness of each skin cleansing preparation for removing the soil was determined as follows Scheme assessed visually:

1. Worse than a commercial toilet soap.

2. As with the standard soap according to 1.

3. Better than with the standard soap according to 1, but worse than with a standard soap containing pumice stone.

4. The same as with the standard soap containing pumice according to 3.

5.Better than with the standard soap containing pumice according to 3,

To avoid accidental errors, each experiment was carried out ten separate times. Here the following results were obtained:

Skin cleansing preparation valuation 1 4th 2 2 3 1 4th 3 5 3

The compilation of results shows one of the dispersion of the particles in the soap bar decreasing synergism, since the rating for skin cleansing preparation 1 is better than that for separate application of the particles and the soap (skin cleansing preparations 4 and 5) were to be expected were.

Claims (4)

cleaning agents have also become known which contain polymers as opacifiers. Claims: Finally, in Belgian patent specification 655 572 and British patent specification 831 856, the use of water-soluble polymers is known. 1. Become a skin cleanser containing a detergent. Combine the known cleaning agents and finely divided particles of a water-insoluble but the desired combination of properties, solid organopolymers, which in combination, namely high cleaning effect and a tact with a mineral oil-water interface - in a comfortable feeling when using, not out of the way the advancing oil phase measured - an io reaching degree. Has contact angle of 50 to 150 ^c , the The present invention provides a skin cleansing Weight ratio of detergent to polymer preparation with a detergent and finely divided part between 9: 1 and 1: 9, thereby more likely to indicate »a water-insoluble, solid organopoly, that at least 99% of the mers which come into contact with a mineral oil polymer particle in at least one extension water interface - smaller in the advancing direction of the oil Measured as 250 microns and in at least phase - a contact angle of 50 to has two directions of expansion less than 125 microns 150 °, the weight ratio of are. Detergent and polymer is between 9: 1 and 1: 9. which is characterized by the fact that at least 99 "" 2. A preparation according to claim 1, characterized marked 20 of the polymer in at least one expansion Characterized in that the polymer particles in all three direction is less than 250 microns, and at least in dimensions are approximately equal. two directions of expansion less than 125 microns are. 3. Preparation according to claim 1, characterized in that all the usual and for the invention are suitable draws that the polymer particles thread-like 25 skin cleansing preparations usable soaps and are. synthetic detergents in communion with all known thinning, stretching, binding and other 4. Preparation according to one of claims 1 to 3, gene additives. To the usable detergents thereby characterized in that the polymer also includes, for example, sodium stearate, sodium dem in contact with a mineral oil-water palmitate, from Ta! g or coconut oil fatty acids interface - soaps and synthetic sulfonated detergents were measured in the receding oil phase - A contact angle of more than zien, such as sodium fatty alkyl sulfonates, alkylarylsulfona-30 ° having. te, fatty alcohol sulfates and fatty glyceride sulfates as well their mixtures with one another. 35 The finely divided organic polymer particles that can be used include those whose surface is as follows is such that neither oil nor water (including borrowed an aqueous solution of the detergent used) can completely displace one another. More precisely, those organic polymers are suitable which in contact with both water and oil (white mineral oil) phase between the Water-oil interface and its own surface The invention relates to a skin-cleaning surface - prepared measured in the advancing oil phase and relates in particular to such a surface in the form of 45 having a contact angle of 50 to 150 and preferably of its liquid, a paste, a piece or 60 to 110. Preparations containing polymers. Rod, which also dispersed a detergent in it, which had a contact angle of less than 50 or more than 150 finely divided, water-insoluble solid particles, kept the desired superiority, including removal of oily dirt and soil. Various preparations have already been made, for example 50 miss. If the preparation is in the form of a white bar soap proposed, emery bar or solid, it is contained in such particles; However, they suffered from the disadvantage, which is very desirable, that the contact angle of scratchiness measured in the back, that they produce an unpleasant feeling in the user, and sometimes even do, is at least 30. With less than 30 lying, damage to the skin by scraping and 55 receding contact angle, the part that the emery particles hold the effectiveness of the oily soil stubbornly regardless of the physical form of the preparation with regard to the removal of oily overall preparation. Do not significantly increase dirt and soil. If the preparation is made from a paste or a liquid dispersion, it doesn’t mean a lot of hand washing paste, the chips of plexiglass a 60 part, because all the material used in the rinsing water size of about 1 χ I χ 3 mm contains, known-übergehl and has been flushed away through the drainage line. will. A rod, however, usually serves the same purpose-British patent specification 1053 237 describes early as a cleaning tool and detergent supplier the use of rayon in the form of a flexible foil in detergents whose surface makes contact with soil dirt. 65 on. And even an ordinary, non-abrasive one. From the USA. Patent 3 382 177, the bri soap bar holds back some dirt, provided it is not rinsed off before repositioning in the soap dispenser, and the British patent 643 864 1009 168 will.
