Cosmetic preparation

Bio invention relates to cosmetic preparations with at least a cosmetically active ingredient.

Pie invention is concerned with the task of producing such a cosmetic preparation with properties which the properties of a preparation produced by one of the known processes in different directions surpass.

The invention consists in that the cosmetically active ingredient of cellulose crystallite aggregates with an approximate uniform degree of polymerization from 15 to 375 with a particle size of less than 1 micron to 300 microns is, the cellulose crystallite aggregates not more than 300 parts, preferably not more than 200 parts each Contains million ether-extractable components.

For the sake of simplicity, the following is used for the cellulose-crystallite aggregates the abbreviation OKA can be used.

In the case of a preparation, in particular in the form of a water (facial toner, hair tonic or the like) or in the form of a cream.

is present, in particular 1% by weight of the CKA has a particle size less than 1 micron.

In the case of a preparation in gel form, CKA with a weight fraction of 3 to 35% are expediently suspended colloidally in the water.

A dry preparation according to the invention is pressed in particular with the OKA as a binding agent.

A product based on oil, wax or fat appropriately contains OKA as an additive and / or at least partial replacement of oil or wax or fat.

The new properties of the preparations according to the invention will be explained in detail below.

The production of CKA with an approximately uniform degree of polymerization of 15 - 375 microns can be assumed to be known (French patent specification 1,194,486 and the literature cited therein). The degree of polymerization depends on the initial cellulose. With regenerated cellulose it is around 15 - 60, with natural cellulose, e.g. cotton linters or cleaned wood pulp 60 - 125, for sulphite pulp 200-300 etc.

The chemical purity of the CKA is extremely high. The asohe content is approximately between 10 and 600 parts per million, while it is between 1000 and 4000 parts per million for commercial cellulose material.

It is well known that the numerous forms of cellulose, such as cotton and wood pulp, non-cellulose ingredients including plant steroids, where it can be assumed that these steroids are chemically bound to the cellulose and are thus physiologically inert State. For example, purified wood contains pulps that are usually called high alpha pulps refer to about 1,000 to about 3,000 parts per million of ether-extractable ingredients, including plant hormones, which cannot be assimilated by the human body. The destruction that occurs in acid hydrolysis The fine structure of cellulose can make the plant steroids more suitable for physiological assimilation do. Aggregates of cellulose crystallites, for example obtained from a refined wood pulp (93% alpha-cellulose; 1000 parts per million ether-extractable components) contain about 800 parts per million of the ether extractables Components. For certain preferred applications of the present invention j should the content of ether-extractable components (including of steroids) between about 50 and at most 300 parts per million, preferably not more than 200 parts per million. Cellulose crystal aggregates obtained from cellulose with a high alpha content, and which contain, for example, 800 parts per million of the ether-extractable components, can be extracted with hot isopropanol in order to reduce the content of essential

909821/1083

_ Zj. -

Reduce extractables to less than 200 parts per million.

In the course of the production of the aggregates of the Oellulose-KClstallite these are washed with water after the hydrolysis of the starting material and the particle size of the single aggregates will vary between about 1 micron and about 300 microns, as can be determined by microscopic examination. These aggregates may then be comminuted to reach betw to products that ale a particle size less. 1 micron up to about 300 microns, and the particle size and particle size distribution can be varied depending on the specific milling method and the length of time that the aggregates are subjected to the milling treatment.

The comminution method that is used with particular advantage consists in grinding the aggregates, i.e. subjecting the aggregates to a frictional or shear effect, with the aid of a high-speed cutting action in the presence of an aqueous medium. The water content of the mixture, which is subjected to the attrition process should preferably be at least about 15 to 25 percent by weight. The aggregate content of the mixture that is to be crushed should be at least 3 percent by weight and, if desired, even more , because the effectiveness of the cutting process increases with increasing aggregate content. For example, if you do rubbing at a consistency of 3% in such a way that at least 1%

909821/1083

with a particle size of less than 1 micron, this leads to a milky dispersion. The relative viscosity or the thickness of the dispersion will vary depending on the situation relative proportion of particles less than 1 micron in size. A lengthening of the attrition process increases increases the amount of the fine particles and accordingly also increases the viscosity to some extent. The stability of the dispersions increases with increasing pH of the medium. At pH values that are essentially between the neutral range and 11 lie, the dispersions remain stable indefinitely.

The aggregates can be dried either before or after the mechanical comminution process. Purely some purposes it is advantageous to only dewater the material instead of drying it, because the aggregates are not dried the cellulose crystallites form dispersions more easily and the dispersions have a better flowing structure, if they are made from an undried material. The aggregates can be dried and fine-grained Form can be obtained, for example by freeze drying, spray drying, drum drying, vacuum drying and Drying by means of solvent displacement.

A gel can be formed from the oil-crystallite aggregates form when about 3 to 35 percent by weight of the aggregates are dispersed in an aqueous or other liquid are. In this case the aggregates form the continuous phase of the mixture. The gel has the physical form

909821/1083

a jelly, a paste, a plastic mass and the like.

The aggregates for the production of water-containing cosmetic preparations can initially be in the form of moist Gels are present, which can serve both to supply the water content of the preparation, as well as to produce it of a well mixed product. The units can be used for the manufacture of dry preparations be used in dry form; the same also applies to P for their use in the production of non-aqueous, oily Preparations. In the latter case, the units are preferably premixed with the oily, greasy and "or" or waxy material to create a seemingly dry, free-flowing one to form crumbly preliminary product and thereby facilitate the final completion of the approach.

A variety of cosmetic preparations can be refined by the addition of the aggregates, although their application, since eie water and oil insoluble are limited to preparations which are at least partially composed of solid materials. The term cosmetic preparation is intended to encompass all types of products that are used in any way in the treatment of the human body for the purpose of cleaning or beautifying, including changing the appearance . This definition should include toilet soaps and shaving soaps and creams, as well as preparations for eliminating body odors and depilatories and finally also skin tanning agents.

As for the technical application of the aggregates for certain cosmetic As for products, they are suitable for creams, which are essentially based on oil, both as additives and at least partially Replacement of the oil, fat and / or wax components of these creams. For example, some of the units can do that Replace almond oil, mineral oil, lanolin, beeswax, paraffin wax, oleic acid or spermaceti oil and the like, which are usually used in creams, whether they are cleansing creams or skin-softening ones Creams or creams to complete skin care (finishing type), including gold creams, fast-flowing Creams, liquid cleansing creams, night creams, massage creams. Vanishing cream, foundation cream and numerous other special creams. One advantage of replacing at least a part of such materials is that that the tendency of the creams to cause staining is reduced, that is, that the creams after the user has applied it to the skin, are less susceptible to picking up or attracting dirt or foreign particles, similarly, the applied creams are less easily smeared off the skin of the user when they are e.g. come into more contact with clothes, sheets, etc. The latter benefit is of particular importance for other creams, such as deodorants including the odor removal creams and special

909821/1083

to eliminate the odor of sweat, which mainly occurs in the Armpit and on the palms and soles of the feet and are therefore particularly easy to put in with clothing Come into contact and soiled them so badly that these types of clothing are often destroyed. The glycerine content of creams to complete skin care (finishing creams), such as dry creams (vanishing creams) or foundation creams can be partially replaced by the aggregates, so as to result in a cream with increased opacity or with an increased degree of whiteness, the appearance of which many users rate higher than the appearance of creams, " soft have a cutting or pearly sheen. However, creams of the latter type can also be produced by keeping the aggregate content low. the Contents of lanolin, petrolatum, ceresin, beeswax, cocoa butter and / or stearic acid in skin-softening creams and dry creams and also from rouge in cream and paste form can be partially replaced to reduce their tendency to get dirty and especially to improve their oily or greasy feel without affecting their spreadability affect the skin. Because the units are easy to lubricate and so is this smearability Give cream preparation without reinforcing its oily character, so the aggregates are also used as additives for Creams that are to be applied to oily skin are useful. The addition of the aggregates is, in short, for many Creams of importance when a stiffening effect is desired,

909821/1083

r r j

In special creams, such as protective creams, the aggregates can with Advantage, for example, can be incorporated by simple addition, and the creams can be of any type, e.g. from a mixture of fats and oils, a jelly containing a physical protective substance, a Emulsion or a soap base. Such Creams are of particular importance to the hands when performing many operations and processes in industrial plants to protect against injury or contamination. Especially the creams that contain physical protective substances, are suitable for taking up the aggregates - available in different particle sizes - on the skin protective zones of varying degrees of fineness and varying smoothness.

In cleaning waters, which usually consist of more or less constant suspensions of mucilage, can the usual abrasives, such as magnesium carbonate, can be wholly or partially replaced by the aggregates in order to achieve the Difficulties arising from sitting down. Magnesium carbonate, which is insoluble and heavier than water, tends to get out of the cleaning water (lotion) when standing a fact that affects the appearance of the preparation and forces the user to use the cleaning water Shake before each use. The application of the aggregates does not just provide an abrasive, but Thanks to its property of forming stable gels and dispersions, it leads to an infinitely stable, homogeneous one Beauty water and makes the addition of the usually

909821/1083

used emulsifiers, such as borax, to be dispensed with. It should also be emphasized as particularly advantageous that the units " Can be used, at least in part, as a substitute for other metal salts and oxides which tend to come off from the beauty waters or to discontinue the suspension. The thickening of the beauty waters and also the creams can easily go through simple addition of the aggregates can be brought about without resorting to special agents such as agar or pectin and the like. More is needed.

Face powder for make-up can also be refined by the presence of the aggregates. The powders consist in the Usually from an opaque agent (! Clay, titanium dioxide, magnesium oxide, zinc oxide, etc.), a lubricating material (Talc, metal stearates and the like. More), an adhesive material (Stearates, clay, etc.) and an absorbent (chalk, Calcium carbonate, kaolin etc.). The aggregates are able to convert metal salts and oxides such as chalk, kaolin, magnesium carbonate, To replace talc, titanium dioxide, magnesium stearate, zinc oxide, P zinc stearate and the like in whole or in part. An advantage this exchange consists in reducing the occurrence of undesirable dermatological side effects. So For example, in the case of magnesium carbonate, a widely used blending ingredient, it is known that some People against traces of elements such as selenium, arsenic, mercury, are sensitive, i.e. to elements in magnesium carbonate may be present as it is difficult to clean. The great importance of this problem is highlighted by the fact underlined that selenium in an amount down to

909821/1083

1 part per million can still be harmful. Other common mix ingredients can be used if they are not in sufficient quantity fine condition, give rise to mechanical skin irritation. Other ingredients, such as talc, will get through the exchange of which eliminates their characteristic earth odor, which otherwise has to be covered. Is of further interest also the effectiveness of the aggregates as sorbents for oil, as this property is beneficial in face powders that are used to treat oily skin the nose. The term "sorption" should be understood to mean the ability of the aggregates to to absorb and / or adsorb oily, greasy, greasy, waxy and watery materials ... in bulk Powders can also be used to replace the starch, and in this way the powder's resistance to the Caking can be improved because the aggregates as such are much more resistant to caking than Strength. Strength becomes soggy from sweat.

In addition to the above-mentioned usabilities, the units are also beneficial for loose face powder preparations, because of their excellent adhesion to surfaces, including the skin. Because of these properties they can take the place of the above-mentioned adhesives with advantage; this also because of the extent to which their particle size varies and their fluffiness or their bulk density can be adjusted. For use in Powdering can have a particle size down to 1 or 2 microns

909821/1083

"when they are usually down to 30 microns may amount to what corresponds to powder passing through a 400 mesh screen. But they are also available in particle sizes available up to 250 and 300 microns and beyond in fractions or batches of uniformly large particles. The apparent or bulk density can be as low as 0.112 or 0.113 g / ccm (7 or 8 lbs.per cu.ft.) which corresponds to a very lightly fluffy material, but it can also be reduced to 0.5 ^ -5 g / ccm (34 · lbs.per cu.ft.)

™ amount. Commercially available corn starch has comparatively a bulk density of 0.59 g / ccm (36.8 lbs.per cu.ft.) on. Due to the light fluffiness of the aggregates and through By selecting the appropriate amount of aggregates to be incorporated into a preparation, the conventional ventilation stage of the face powder prior to packaging can be dispensed with. With small particle sizes, for example up to 30 or 50 microns, the aggregates consist of one imperceptible fine, easily spreadable or friable powder,

* which to mix with even the most delicate cosmetic Px products is well suited. In addition to the properties just mentioned, the aggregates can be equipped with appropriate Selection of the particle size, for example by mixing fractions of different particle sizes an alternating one Degree of opacity can be imparted. In this way, the opacity of a face powder can be varied. From this it can be seen that the aggregates as such make up most, if not all, of the

909821/1083

powder have the required properties. By incorporating the usual amount of a desired dye and Of the desired perfume, a complete, aesthetically pleasing face powder can be created that is suitable for sioh already causes a matting effect and which can be used as such or as a powder base with or can serve without the addition of dyes and perfumes, the only small additives have to be added, un to the desired ready-made powders for dlejpflege the various Skin types to arrive.

For compact powders, including face powders and blushes, which can be pressed after adding a binding agent such as gum arabic, gum tragacanth, glycerine, sorbitol and the like the application of the aggregates make the incorporation of a binder unnecessary, since the aggregates in themselves dry or wet to any desired degree. Can be used in conjunction with loose powders The aggregates serve as a base for the production of various types of compact powders, and they can be used in this shape make up the main component of the finished product.

The aggregates can also find technical application in lipsticks, and here they can be one or more completely or partially replace the oily constituents, for example the fats and waxes, the greasy feel is advantageously improved without a loss of lubricant

909821/1083

'ι ~ r ι

availability occurs and at the same time the dimensional stability is reduced. To the fat and waxes that usually Used in lipsticks include beeswax, Carnaubawaohs, cerosin, lanolin, Schnalz, mineral oil, petroleum jelly and the like. The commonly used flavors for the lipsticks, which usually consist of a volatile, water-immiscible organic ester thanks to the good sorption capacity of the aggregates for such compounds are better held. The aggregates form free ^ flowable, apparently dry mixtures with the taste substances and can thus facilitate the manufacture of lipsticks, because they serve as carriers for the introduction of these volatile compounds in the Produktionsaneatz, so that the losses can be reduced to eschmaeksstoffen ^u in this way.

In the case of preparations for eyelash care, such as, for example, eyelash make-up, the units can replace the usual soaps such as triethanolamine tearate, triethanolamine oleate and the like } thereby making the preparations less irritating to the eyes. In addition, the make-up stone can itself thanks to its compressibility the aggregates can be manufactured more easily. The waxes that are used in such preparations and also in roll-on make-up and Make-up pastes (roll-on mascara; cream mascara) are often used, but can be at least partially replaced the advantages that correspond to those given in the case of the wax replacement have already been described. Due to their small particle size and their good adhesion

909821/1083

firmness, the aggregates are able to give the eyelashes a clean appearance, because they have the thick, pasty or even crumbly appearance that sometimes occurs when using commercially available preparations, or the too conspicuous appearance, which when using some enamel-like preparations: to be observed, to avoid allowing. The addition of the aggregates also enables a larger selection of dyes to be used, and in this way one can become independent of the common, but at least somewhat dangerous, use of silver nitrate with sodium thiosulphate. Suitable colorants are, for example, natural pigments including carbon black, ocher, sienna and umber colors, ultramarine and the like. In the same way, the aggregates can be of value for other cosmetic preparations, such as are used, for example, for cosmetics of the eye in the form of eye shadow pencils, eye rim pencils and eyebrow pencils.

The aggregates can also contain certain ingredients in depilatories replace, in particular, the earthy fillers such as talc and lime, also whiteners such as barium sulfate, magnesium oxide and titanium dioxide, with the advantages described above occurring.

Especially with deodorants, such as odor removing agents Body sweat preparations and preparations, usually simply composed of an active deodorizing agent and a cream base can consist of the aggregates

909821/1083

ointment form the basis ". Suitable preparations for eliminating odors can be made, for example, by mixing one or the other several active ingredients, such as hexachlorophene, bithionol, salicylic acid, zinc peroxide, zinc phenol sulfonate, boric acid, Benzoic acid, hydroxyquinoline sulfate and the like, with the aggregates in gel form, and the resulting mixture, which the appearance, the handle, the lubricity, the applicability and the adhesive strength of a cream preparation owns, can then be used as a deodorant or in many cases as a mixture base, which only small additions needed to deliver the finished product. Such a mixture or product has the advantage that it is easy to lubricate without showing a greasy character. It gets there with no modifications or incorporation of additives used, it dries quickly after application to form a fine-grained, firmly adhering coating, which is easily washable with water. The aggregates in this coating layer cause on the fabric or the The item of clothing with which it comes into contact do not have a stain or act on them in any other way. In a similar way Way, a sweat elimination preparation can be made by mixing with one or more common active ingredients, such as alum, aluminum chloride, zinc chloride, aluminum acetate, Zinc sulfate, zinc phenol sulfonate, tannic acid and tannin and the like, can be produced with the aggregates present in gel form. For the production of the preparations just mentioned are both aqueous and non-aqueous aggregate gels from

909821/1083

Meaning.

The crystallite aggregates can also be used in shaving creams, and soaps improve lathering shaving soap by lathering it stiffen and stabilize. Presumably the tiny particles of the aggregates reinforce the air trapping Walls of the foam and thus prevent the foam from breaking easily. Pie units can at least partially do the usual Replace whiteners, the talc, used in some shaving soaps and hemostatic pens, and wear them thus helps to reduce or avoid the characteristic earth odor of the talc. In soap powder they can Aggregates also fulfill the purpose of caking impede.

In sun protection preparations, the aggregates can, as β * opaque are to replace the known opaque scattering agents for ultraviolet rays, such as talc and titanium dioxide, the already mentioned advantages occur. In such preparations and also in many other preparations including With sun tanning creams and leg paints, the aggregates prove to be easy to smear without becoming greasy appear, and also the adhesive strength of the product on the skin is increased and its washability with water is improved. Since such preparations are often in dispersion form present, a further advantage is expressed in the stability, which the dispersions by the presence of the Aggregate is awarded. In this context, simple, two, three or four components are of technical importance.

909821/1083

be prepared components existing sunscreen preparations containing by mixing a base material such as petrolatum or zinc oxide or lanolin, with the units containing QEi ₁ which, for example, 3 to 25 percent by weight of aggregates, residual water. An active ingredient that protects against sunburn can be mixed in, which should help to keep the harmful radiation away. As such an active ingredient, aoetanilide, cholesterol, p-aeineoic acid and salicylic acid salts, ohinine salts, tannins and the like can be used. These components can form compatible mixtures. Braununga make-up, which can either be in loose powder form for the face and other body surfaces or in compact block form, can be improved in its properties in the manner described for make-up powder.

As for manicure preparations, water washable nail varnishes can be made, which simply consist of the aggregates, a coloring substance and water, and in which the aggregates, especially those of the smallest particle size, produce the necessary adhesive strength on the nails. Such preparations are important when applied to the nails for a single, short-lived occasion after which they can be removed by simply washing your hands in water. Since they are harmless they can also be used by children.

Face masks can be improved in terms of their adhesive strength and their washability with water through the addition of the aggregates

909821/1083

which, in addition, are less desirable inorganic ones Components such as bentonite, fuller's earth, Can replace kaolin, infusor earth.

Bath additives or effervescent bath preparations can be improved by the units with regard to the stability of the bubbles that arise. As already mentioned above, the aggregates act as stabilizers for the bubbles and the foam. They can form Λ which tends to viscous, sticky solutions in place of the conventional stabilizers, such as Methylcelluloee, occur. In the case of fragrant bath additives or dusting powders, the aggregates can replace the conventional talc and colloidal clay as absorbents, and they can also replace titanium dioxide in its function as a whitener. They can also take the place of agents for improving the adhesive strength, that is magnesium or zinc stearates. In other fragrant preparations, the aggregates can be mixed with a perfume to provide an apparently dry, solid, free-flowing, fragrant mixture or olfactory pad which can then be used in the linen cupboard or wardrobe or in olfactory pad pouches. The aggregates hold the perfume firmly so that the fragrance is only released gradually over a longer period of time. Similarly, other solid shapes such as pins, pressed blocks, and the like can be made.

909821/1083

The aggregates of the Oellulose Crystallites can also be used with advantage are used in detergent preparations. Such preparations consist of crystallite aggregates of cellulose and a washing active ingredient, such as a normal soap (alkali salt of a higher molecular weight fatty acid) or one of the large number of known synthetic surfactants which have supplanted soap in many uses. The detergent substance should be in be present in the mixture in an amount sufficient to give the mixture its characteristic detergent properties to rent. For example, in certain toilet soaps, the aggregates can be used instead of the total amount or one Part of the coconut oil can be used, which despite its well-known sharp and skin-irritating effect in large Scope as a foam concentrate is used. During this exchange, the aggregates give their particle size from 30 to 100 microns can be, also the property of lubricity without appearing greasy, and they improve the strength of the foam. They can also serve as whiteners and as an abrasive in soap bars and soap powder, taking they prevent the latter powder from sticking together.

Tooth powder preparations can also be protected from caking by adding the aggregates, whereby the aggregates at the same time hold the flavors better.

Not the least important characteristic of the aggregates is their easy washability from the skin with help

909821/1083

of water, regardless of the type of preparation to which they have been added. They are not in water soluble but dispersible therein and easily washed off the skin.

Any preparation in which settling or sedimentation problems occur can be improved by adding the aggregates, and it has been found that they are able to transfer their ability to form stable dispersions and compounds to more complex mixtures. The elimination of the settling _Λ is preferably possible in preparations in which the aggregates are used in gel form, and this success occurs due to the higher content of aggregates that the gels have.

As noted, many of the cosmetic mix ingredients that the aggregates can replace are Toxic to some extent. Magnesium oxide and magnesium carbonate, for example, have a moderate local irritant effect on the skin or the mucous membrane, which appears either acutely or chronically only slightly irritating. Caustic soda and itzkali are very irritating. Almond oil, beeswax, lanolin, Sperm aceti oil, ceresin, carnauba wax, castor oil, starch, It was found that tragacanth gum and palm kernel oil have a mildly allergic effect. Practice talc, borax and caustic soda when de are inhaled, have a moderate local toxic effect,

909821/1083

while the same effect is only slight with calcium carbonate, triethanolamine and starch. If borax gets into the stomach, so it has a moderate toxic effect, while calcium carbonate and triethanolamine show only a minor effect here. If caustic soda and caustic potash get into the stomach, they develop an extremely toxic effect.

On the other hand, the crystallite aggregates are so harmless that they can be eaten without seriously affecting them to show toxic effects. They have a mild taste and odor, are white in color, and are physically similar to starch.

Apart from the exceptions already mentioned, the approaches are as a rule according to those for dl · Manufacture of cosmetic Preparations or similar commercial products manufactured using the usual methods. One common and effective method is there in manohen cases in it, from those in Gelfora or in the form of a Starting from dispersion aggregates present and mixing in the other ingredients therein. Is making one If dry powders are desired, the mixture obtained can be subjected to spray-drying.

The invention is illustrated by the following examples.

The aggregates of cellulose crystallites, which are used in the examples below, were produced by hydrolysis of ketchiken sulfite wood pulp with a 0.5 percent by weight aqueous solution of HCl at 121 ⁰ O (250 ° F) for one hour, with one material incurred, which was a thoroughly

909821/1083

had an average degree of polymerization (average level-off DP) adjusted to an approximately uniform value of 220 and a purity of over 96%. This material was dried in a vacuum drying cabinet at 70 ° 0 (158 ° F) to a moisture content of about 4 to 5 weight percent. It was then sieved, and the fraction that passed through a 325 mesh screen (44 microns and less) _; was used.

easily reconcilable to the skin. Were the cream patterns of wiped the skin with a cleaning paper, the skin treated with the Greme pattern "D" appeared softer afterwards,

Example 2

A cleaning water (lotion) for the hands was made from the following approach:

Crystallite aggregates 15 g

Glycerin 73

distilled water 10 peppermint oil 2

Sodium Lauryl Sulphate trace

The cleaning water was viscous, but easy to pour and showed a glossy pearly white appearance. It was easy to rub on the hand and gave the impression easy to smear without appearing greasy. To no visible trace of the aggregates was detectable after the applied coating had dried.

From this approach, two genes were made, one of which one contained the aggregates and the stearic acid and the other consisted of the heat of the components. Either of the two Mixtures were heated to 70 ° C and then mixed. The resulting product was in Porn »a soft, white, odorless fast that is easily dispersed on the skin and left a not greasy feeling. It can can be easily wiped off the skin with a cleaning paper. After applying to the skin and drying it lay the coating layer in the form of a white, firmly adhering, non-greasy layer that could easily be removed by wiping it off

The pattern "G ⁿ , which contained calcium carbonate as an abrasive, was a commercially available material, while the pattern ^N H" contained the crystallite aggregates in place of the calcium carbonate. Both samples were mixed thoroughly and then filled into sealed containers. Been standing for several days the ^G was Eruch repeatedly checked both patterns and it was clearly seen that the pattern containing the aggregates' stronger although originally used for the flavoring agent (peppermint) smelled, for the preparation of both patterns, the μ same amount of the flavoring agent wafc. When rubbed with the finger, both samples had the same sensation as with an abrasive, with sample "H" having a less abrasive effect than sample "G". In appearance, sample ¹¹ H "made a softer impression and appeared to have a slightly flaky character, which sample" G "did not show, which rather represented a white powder, similar to the known preparations.

As already mentioned, the aggregates are suitable for use in cosmetic preparations that contain a component ' contain in solid form, that is, a solid component other than the aggregates. If their presence isn't harms, they can also be useful for liquid preparations that do not contain solid components, so for Example for beauty waters (lotions), emulsions, solutions, liquid creams or other liquid mixtures. If also the aggregates are normally in a solid state, whether or not they are in a liquid such as water

suspended or immediately in a solid state, they are nevertheless able to exist in a form that makes it questionable whether they are in a solid state or not. This is the form obtained by dispersing aggregate particles of extremely small particle size, for example below 1 micron, preferably below 0.5 micron, in water. Under these conditions, the aggregates form what is known as gel particles, whereby the violets are so swollen that one is faced with the question of whether they are in a solid or a liquid state. Ie Bahaen description of the invention, the terms "aggregates" or "solid aggregates" or "solid Partikelohen" or "solid Fora ¹¹ or" finely divided solid form "these gel particles of the aggregates also comprise as the aggregates of larger particle size.

From the foregoing description, it can be seen that the present invention has improved cosmetic preparations relates to "the Sri Stallit" aggregate β of cellulose and at least one active cosmetic ingredient or component in such an amount and in such a suitable form that their characteristic cosmetic effect or property of StottQiechu & g is bestowed.
