Description

FIELD OF THE INVENTION

The present invention relates to a powdered composition and an aqueous cleaning composition and uses thereof.

BACKGROUND ART

Commercially available cleansing compositions useful for cleansing the skin and hair usually contain very high levels of water (about 60-80% by weight) to provide a gel-like consistency in which these cleansing compositions are ready for consumer use .

However, the water contained in the cleaning composition does not have any cleaning or skin/hair care properties per se. However, this means that when transporting the ready-to-use cleaning compositions z. For example, a large amount of "useless" water is transported from the production site to the distributors or supermarkets and thus ultimately a large amount of energy (e.g. in the form of fuel) is consumed just for the transport of water.

In times of drastic climate change, however, there are various efforts to avoid the transport of "useless" water, e.g. B. Cleaning compositions in the form of a soap bar.

However, such products are often not accepted by the end consumer, since the end consumer states that they do not have the usual gel-like consistency. Another point that is often raised is that the cleansing as well as the hair/skin care properties of the soap-type cleansing compositions are different from those of the gel-type.

OBJECTIVES OF THE INVENTION

Thus, an object of the present invention is to provide a composition that on the one hand does not contain "useless" water and on the other hand offers the same consistency and the same cleaning and skin/hair care properties as the commercially available gel-like, ready-to-use cleaning compositions.

EXAMPLES

The invention will now be illustrated with reference to specific examples. However, the invention should not be limited to these examples.

Example 1 Preparation of a powdered composition according to the invention

Mounting step: In a Lödige mixer, 32.15 g of sorbitol (non-salt substrate) are provided. With stirring, 0.5 g of sweet almond oil (conditioning agent) and 1.0 g of a fragrance oil are added to the sorbitol. Mixing is continued until all the oil is absorbed by the sorbitol, which was after stirring at 120 rpm for 60 seconds.

Mixing step: The powder obtained (sorbitol-based oils) remains in the mixer and the following powdered components are added to the powder: 2.4 g arginine (conditioning agent), 0.8 g guar hydroxypropyltrimonium chloride (conditioning agent), 7.3 g sodium chloride ( viscosity-adjusting agent), 3.75 g citric acid (pH-adjusting agent), 2.5 g sodium polyphosphate (chelating agent), 0.75 g sodium benzoate (preservative), 1.75 g potassium sorbate (preservative) and 0.1 g freeze-dried Aloe Vera powder (moisturizing agent). The powder components are mixed at 120 rpm for 50 seconds. Finally, the following powder components are added to the resulting powder mixture: 28.0 g sodium cocosulfate (surfactant), 6.5 g sodium methyl oleoyl taurate (surfactant), and 12.5 g disodium lauryl sulfosuccinate (surfactant). All powdery components are mixed for 20 seconds at 100 rpm and 100 g of a powdery composition according to the invention are obtained.

The D50 particle size (median) of the powdered composition obtained in this way was approximately 178 µm and the D90 particle size (median) was 549 µm (measured with a Mastersizer 2000 at 3 bar) and the residual moisture content was 1.1% (according to Measurement according to DIN51718). The amount of surfactant present in the powdered composition was 47 g.

Example 2: Preparation of an aqueous composition according to the invention

20 g of the powdery composition obtained in Example 1 was provided in a bottle. 80g of tap water (40°C) was added to the powdered composition. The bottle was capped and the contents of the bottle shaken by hand for 60 seconds. The powdery composition was completely dissolved in the water and no solid particles remained in the water. After the shaking stopped, foam was observed on the surface. The contents of the bottle were then left to stand at room temperature for (at least) a further 30 minutes. The foam decomposed within this period. An aqueous cleaning composition with a yellowish, iridescent appearance was obtained. The measured viscosity was 8000 mPa*s (as measured with a Brookfield viscometer at 20 +/- 5 °C, a 0.5 bar and 20 rpm). The amount of surfactant present in the aqueous cleaning composition was 9.4 g.

Example 3: Study of the foaming properties of the aqueous composition according to the invention

The foaming properties of the aqueous composition according to the invention as obtained in Example 2 were examined and compared with the foaming properties of a commercially available gel-like ready-to-use aqueous cleaning composition. 100 g of a commercially available gel-like ready-to-use aqueous cleaning composition was composed of the following components: 80.0 g water (purified), 1.30 g fragrance oil, 0.50 g PCA glyceryl oleate (conditioning agent), 0.20 g glyceryl oleate ( conditioning agent), 0.30 g hydrogenated wheat protein (conditioning agent), 0.10 g allantoin (conditioning agent), 0.40 g sodium benzoate (preservative), 0.55 g citric acid (pH adjusting agent), 1.00 g sodium chloride (viscosity adjusting agent), 11.0 g sodium cocosulfate (surfactant), 0.50 g disodium cocoylglutamate (surfactant), 3.00 g cocoglucoside (surfactant) and 1.60 g cocamidopropyl betaine (surfactant). The viscosity of the commercially available aqueous cleaning composition was 12,600 mPa*s. The amount of surfactant present in the commercial aqueous cleaning composition was 16.1 g.

The examination of the foaming properties proceeded as follows: A 5 g sample of each aqueous cleaning composition was dissolved in 500 g distilled water and heated to a temperature of 42°C. 101 g of each solution obtained in this way was carefully transferred to a 250 ml (Ø 70 mm) beaker. There should be no foam in or on the solutions. The solutions were then stirred using a turbine stirrer (Ø 28 mm). The stirrer is inserted into the solution only half its length (ie, half of the stirrer was in the solutions and half of the stirrer was out of the solutions). The temperature of the solutions during this stirring must be kept between 40 and 42 °C. The height of the foam formed on the top of the solutions is measured using a standard ruler. Stirring was carried out at 1500 rpm for 120 seconds. A first set of measurements was made 30 seconds after the agitation was stopped. A second set of measurements was taken 180 seconds after the agitation was stopped. A third set of measurements was taken 300 seconds after the agitation was stopped. Each series of measurements consisted of four measurements, with each measurement being carried out at a different location. The results are given in the following table:
