SOLID COLOR PREPARATIONS (II)

FIELD OF THE INVENTION

[0001] The invention is in the field of dye preparations and relates to special powders, in particular for use in so-called "HOLI festivals".

STATE OF THE ART

Holi (Hindi, f., ^ Tef, holT) which is possibly one of the oldest festivals ever, but certainly represents the most colorful of all dar. Five days after the full moon is Rangapancami (Ranga = color, Pancami = the 5th lunar Day), the second day of the festival. On this day, even in the very tradition-conscious nation, all barriers of caste, gender, age and social status will be lifted. It is hilariously celebrated and sprinkled and sprinkled each other with dyed water and colored powder, the gulal. Who refuses the arrogance, at least discreetly brushed each other with some powder paint. Despite all the changes in modern Indian society, the sacred significance is still clearly recognizable, for example, the colors are still ordained on the altar today and people bring blessings. Originally the color powders were made from certain flowers, roots and herbs that have a healing effect. Today, synthetic dyes are often used, which can sometimes even be harmful.

[0003] On the first day, a fire is lit at night, burning a figure of straw, the so-called Holika. Various myths deal with this demon; one of the most famous stories tells:

Child prince Prahlada was to be persuaded by his father to pay him all godly honor, but the boy continued to worship only Vishnu. By various means, the king now tried to kill his son, but each time Vishnu intervened and rescued the child. Finally, the king resorted to a ruse: his sister Holika, who was protected from the fire by special forces, was to jump into the fire with Prahlada on her lap, thus burning him. But the flames spared the child, leaving Holika with only a pile of ashes.

Then celebrate the people as a reminder of the destruction of the demon in the feast Holi. Closely related to Holi are the stories of Krishna's childhood and youth. He too should have celebrated the game of colors with his companion Radha and the other shepherdesses. Here Hindus interpret the tender "play" with the colors as "purple" Krishnas, symbolizing the "divine game". A festival very similar to the Holi, Nouruz, is celebrated in Iranian culture.

Like all festivals, Holi is very complex in its meaning. In the spiritual realm, as seen in the related mythology, it conveys the message of the triumph of good over evil. In nature, on the other hand, it marks the victory of spring over the winter, because the festival begins with the blossoming of nature. An important point is also the reconciliation aspect for the people, because it is said that one should also bury old disputes in these days. Often it is customary to consume to Holi a Bausch called intoxicant. Some people also drink the traditional banned alcohol, which is becoming more and more of a problem, especially in the cities due to the resulting violence.

Meanwhile, Holi is adapted in various parts of the world for commercial, party-like events - such. For example, at the Holi Festival of Colors, which was the first commercial event of its kind in Germany in 2012, which kicked off in Berlin. On these occasions, mostly young people celebrate boisterously and throw color powders - the Gulals described at the beginning - which are referred to here as "Holipulver" or "Mikrokonfetti".

These powders are chemically nothing more than solid dye preparations, which may only be placed on the market, if they numerous provisions, ranging from the Chemicals Act on the Hazardous Substances Ordinance, the Cosmetics Ordinance to the Particulate matter, sufficient.

In fact, the dangers that can emanate from such powders are not negligible. This begins with the dermatological compatibility, because the substances are brought into contact with the skin and not infrequently also the mucous membranes and, depending on the proportion of fine dust, can also be absorbed via the lungs. Another problem is that finely divided preparations tend to form dust explosions, which must definitely be ruled out in the intended application. Since dyes and carriers ultimately remain in the environment, they must also belong to the lowest possible water hazard class.

But that's not all: the powders must, of course, also meet the requirements of the consumer. Above all, this means that while they are throwing in the air they fly high, but not far. Powders that are too light are carried by the wind and then do not go down as desired on the revelers, but settle down on the festival area on passers-by, vehicles and the washing of the neighbors. The associated anger is easy to imagine. However, if the powders become too heavy, they will not remain in suspension for long, but will fall back to the ground near the throw point, causing them to feel as if it is raining rice. That too is absolutely desirable.

Previously on the market products - which are partially imported directly from India - represent anhydrous mixtures of magnesium stearate or similar water-insoluble carriers and lacquered or resin-applied dyes that do not meet the statutory requirements described above and not even in Traffic should be allowed. Alternatives are dry blends based on dyes, which are applied to corn starch or rice powder. Here it comes to the described disadvantages in flight and throwing behavior. From the German Utility Model DE 20 2013 006887, which is also attributable to the Applicant, corresponding solid dye preparations are known, the starch, silicas in two different particle sizes, saline and dyes and at least 15 wt .-% water. These powders already have very good throwing and flying behavior and are essentially dust-explosion-proof, but there are even more stringent security requirements that have to be met by the authorities in view of a series of serious accidents in the recent past.

The object of the present invention has thus been to fully meet the initially described complex requirement profile both in terms of legal provisions as well as with respect to the application. The preparations should in particular be toxicologically and dermatologically harmless and not water endangering and have a throwing and flying behavior which can be briefly described as "high, but not far" and thereby have a further reduced tendency to dust explosion tendency.

DESCRIPTION OF THE INVENTION

The invention relates to solid dye preparations containing

(a) starch with a grain size d50 in the range from 3 to 20 μιη,

(b) silica having a particle size d50 in the range from 10 to 80 μιη,

(c) silica having a particle size d50 in the range from 80 to 140 μιη,

(d) sodium chloride with a particle size d50 in the range from 6 to 25 μm,

(e) Dyes as well

(f) fragrances and / or flavorings,

with the stipulations that they

(i) have at least 15 wt .-% of water and

(ii) based on the total composition, at least 70% by weight of all particles have a particle size of not more than 63 μm.

Particularly preferred are those preparations which

Contain from about 18% to about 28% by weight and more preferably from about 20% to about 25% by weight of water, and / or

Based on the total composition not more than 25 wt .-% of particles containing a particle size in the range of 63 to 250 μιη, and / or

Based on the total composition not more than 2.5 wt .-% of particles containing a particle size above 250 μιη have.

All particle sizes or particle size distributions were measured using a Mastersizer 2000, Version 5.60 from Malvern Instruments Ltd. certainly. Surprisingly, it was found that dye formulations of the type claimed fully meet the initially described complex application requirements profile. The preparations are toxicologically and dermatologically safe and belong to the water hazard class 1. Although the color powders are marketed as cosmetic formulations, you could even consume the powders because they are made from food raw materials, which underlines the special safety of the products.

In addition, but you also meet the high demands on the flight and throwing behavior, i. E. they are heavy enough not to get carried away but light enough to be thrown high in the air. For this they have a fineness, which is not unpleasant when raining on the body surface.

By selecting starches, silicas and salts, each with specific particle sizes color powder mixtures were obtained in turn with their characteristic characteristic grain size profile, on the one hand continue to have the desired performance characteristics, however, compared to the aforementioned prior art, a further reduced Have a tendency to dust explosions and thus meet the strictest current requirements.

STRENGTH

As organic carriers (component a), organic starches are particularly suitable. These include, in particular, corn and rice starch, but in principle other vegetable starches may also be used, such as potato starch. Also suitable are high-starch products, such as ground rice powder. In a preferred embodiment of the present invention, starch is used which essentially corresponds to the following particle size distribution:

The mean of the particle size distribution is preferably in the range of 12 to 13 μιη, the maximum of the distribution is about 14 μιη. [0022] SILICA

For the performance properties of the preparations, it is also critical that two different grades of silica, especially precipitated silica (components b and c) are included, which differ by their average particle size (d50). The silica acts as a binder for the water contained in the formulation. It has surprisingly been found that optimal flight and throwing behavior is achieved only in the presence of on average very small and very large silica particles, since the water binding is very important for the weight of the particles.

For this purpose, on the one hand silica qualities are used as component (b), which have a particle size d50 (Coulter LS 230) in the range of about 10 to about 14 μιη and in particular 12 μιη. As component (c) are preferably silica used which have a particle size d50 (Coulter LS 230) in the range of about 100 to about 140 μιη and in particular of about 120 μιη. Such materials are beispiels-, under the trade name Sipernat ^® 22 and Sipernat 22S (Evonik) are commercially available.

SODIUM CHLORIDE

The presence of sodium chloride (component d) is mainly used for explosion protection, but also as a mixing aid. In principle, it is possible to exchange NaCI for other unobjectionable salts. In a preferred embodiment of the present invention, sodium chloride - or an exchange salt - is used, which essentially corresponds to the following particle size distribution:

EXAMPLES

Preparation Examples 1 to 5

Corn starch, the two silica grades and sodium chloride were metered in successively in a Lödige mixer and mixed together for 2 minutes. Subsequently, an aqueous dye solution was injected at a pressure of 4 bar and the preparation was mixed for a further 6 minutes. Despite the high proportion of water, dry powders were obtained which could be filled directly without further measures. While in the inventive examples, corn starch and sodium chloride was used with an inventive particle size distribution (quality 1 - d50 _(St Äri <e): 13 μιη or d50 _(NAC i): 20 μιη) were in Example 2 Raw materials used, the whose grain sizes outside Specifications were (quality 2 - - d50 ( _S strength): 25 μιη or d50 _(NaC i): 35 μιη). The composition of the powders is shown in Table 1:

Composition HOLI powder

Determination of safety parameters

The particle size distribution in each case a sample of Example 5 and Comparative Example VI was determined by sieve analysis near DIN 66165 part 1 and 2. In this case, a defined amount of the material to be examined is separated by one or more sieves in fractions and determined their mass fractions. The results are shown in Table 2.

Subsequently, the explosive ability was examined. This was carried out in a 20-1 apparatus according to VDI 2263-1 and DIN EN 14034-1 + 2. In this test method, various dust concentrations are swirled in a 20-L ball and exposed to a 2 kJ detonator. If an overpressure of 0.2 bar is reached or exceeded, the substance can be classified as dust explosive. The results are shown in Table 3. According to the results of the investigation, the color powder according to the invention is superior to a very good product from the prior art at high concentrations in terms of dust explosion safety.
