Description

3. Preparation according to claim 1 characterized

draws that the polymer particles are thread-like
•. For the invention are all customary and for

30 skin cleansing preparations usable soaps and synthetic detergents in association with all known thinning, stretching, binding and other agents Additives. The detergents which can be used include, for example, sodium sulphate, sodium 35 palmitate, made from tallow or coconut oil fatty acids Soaps as well as synthetic, sulfonated detergent

zien, such as sodium fatty alkyl sulfonates, alkylarylsulfonate

te, fatty alcohol sulfates and fatty glyceride sulfates together with their mixtures with one another.

_4O The finely dispersed organic polymer particles that can be used include those whose surface is such that neither oil nor water (including an aqueous solution of the detergent used) can completely displace one another. Overall ₄₅ stated more precisely to those organic poly- suitable

The invention relates to a skin cleaning mere, which in contact with both water and preparation and relates in particular to such in the form of oil (white mineral oil) phase between the a liquid, paste, piece or water-oil interface and its own top bar, that a detergent and dispersed in it, surface - measured in the advancing oil phase - finely distributed, water-insoluble solid particles have a contact angle of 50 to 150 ° and preferably hold. 60 to 110 °. Preparations with polymers,

Various preparations have already been proposed, for example those with a contact angle of less than 50 "or more than 150 °, bar soaps, which have emery, allow the desired superiority of bc-like particles to be maintained; however, they suffered from the subsequent removal of oily dirt and soil that they miss reaching the user discomfort _55th the cause of receding oil by harshness and sometimes even tat phase measured contact angle greater than 30 degrees, the skin is neuter damage by scraping and particularly in the form of solid rods or that the abrasive Particles do not significantly increase the efficacy of the preparations with regard to the removal of oily substances with a receding contact angle under dirt and soil.

From the Austrian patent specification 224 785, the form of the overall preparation is the oily earthine Hand washing paste, the shavings of plexiglass a rich stubborn solid. Fixed rods serve the usual-size of about 1x1x3 mm, known to be used as a cleaning tool and degewed at the same time, external suppliers. Its surface makes contact with soil dirt, and even one used to Using rayon in the form of a flexible, non-abrasive soap bar holds some earth foil in detergents. dirt back, unless it is rinsed off before re-filing in Aus der USA.-Patent 3 382 177, the bri soap container. Ebe such a rod

It is therefore desirable that the oil removed from the skin in about: 1000 parts by weight of hot water dissolved from the bar surface, easily rinsed off . In the resulting solution, about can, and this happens if the remaining 20 parts by weight of neoprene rubber powder is stirred in, the contact angle is more than 30 °, the particles of which in all three directions are 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 should have a contact angle of a diameter, ie a minimum dimension, which measured in the advancing oil phase of at least 0.1 microns, and important is 15 about 105 ° and in the receding oil phase also that it was at least 99% a maximum dimension of about 70 °. The dispersion obtained in this way elongation of not more than about one millimeter was dried, powdered and in a usual have. With the expression tabletting machine used here pressed into rods, the "finely divided particles" are thus such particles moisture content according to customary methods of. 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 up of fibrous particles as well as powdery masses with un- Group of people who had their hands soiled with regularly shaped or spherical particles coiloidal graphite emulsion in mineral oil, desirable, but not necessary, on hand washing. Ability examined. However, it was found that the particles neither had sharp edges nor the hand washing test, and that the polymer material had conditions, but on the one hand a comparatively low flexural modulus, namely a similar but neoprene powder-free soap bar and those below about 3.52 · 10 kg / cm ² in order to provide the highest level of comfort on the other hand to a rod made of commercially available mecha. In particular, 30 nicer soap is repeated, the 40 percent by weight otherwise desirable that each contain 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.

This preparation was found to remove from normal hair washes Scum deposits and oil grime from the scalp are found to be unusually effective.

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.

A test person soiled their hands with a standard dispersion of graphite and oil and then washed his dirty hands with water and one of the following skin cleansers :

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;

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

The skin cleansing preparations 1 and 2 were in an amount of 3.0 g used for washing. On this basis, the amount of the in the skin cleansing preparations 3 to 4 neoprene particles used are determined.

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

Step 1; First, the hands were made with a commercially available piece of a pumice stone containing it Washed with soap, then with a paper towel and finally for at least 10 minutes at room temperature air dried.

Step !: A drop of a colloidal dispersion of Apply graphite in oil and apply it evenly to the entire palm of the hand with the fingertips of the other hand distributed.

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 Toilettensei ^f e.

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 pumice stone soap according to 3.

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

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