The composition of the cleansing bar comprising (A) from about 1 to 30% activating powder comprising (a) 1 to 70% (by weight of the powder) is useful additives; (b) 15 - 98% (by weight of the powder) a carrier having a melting point above the temperature in the drying chamber, in which receive the specified activating powder; (C) 1 - 10% (by weight of the powder) water; (d) 0 to 30% (by weight of the powder) subsidiary means for the deposition/facilitate processing, selected from the group of anionic, cationogenic, nonionic and amphoteric surfactants and cationic and hydrophilic polymers, and (B) 99 to 70% of the chips, including 5 - 90% of complex surfactants and surface-active substance selected from the group consisting of soap, anionic surfactants, nonionic surfactants, amphoteric surfactants, cationogenic surfactants and mixtures thereof. Moreover, activating powder obtained by the spray drying method. A method of manufacturing the composition of the cleansing bar, in which (a) and (B) receive separately, in cotney drying at 80 - 200oAnd pressure 0,10 - 0,30 MPa. (A) and (B) are blended, passed through the screw machine and ekstragiruyut, resulting in getting the bars. table 2.

The invention relates to compositions for washing bars, in particular to synthetic compositions for bars that have a superior ability to deliver useful additives. In particular, the invention concerns powder adjuvants, including (a) mineral supplements, (b) media (e.g., soluble or partially soluble starches, water-soluble non-crystalline solids or semi-crystalline water-soluble solids), (C) water and optionally (d) an aid to sedimentation/facilitate processing and activating these powders are mixed with shavings for detergent bars before grinding, extrusion and stamping bars. The present invention also relates to a method of manufacturing these bars, and can be used in the chemical industry, in the production of hygienic and cosmetic products.

It is difficult to develop a composition for the manufacture of detergent bars (lump of soap) that can deliver sufficient quantities is ocess the manufacture of bars (for example, useful additive can be sticky and clog the machine or it may have a high viscosity and do a song for bars difficult to extrusion), and/or these useful additives can have a negative impact on consumer properties of the bars (e.g., foaming).

For example, as a rule, water-insoluble mineral supplements tend to lower mylyaschie properties. In addition, even if these substances and included in the bars, the effective applied to the skin water-insoluble useful additives of the bars is difficult because of high content of water-insoluble particles, such as contained in the bars fatty acids or waxes that can compete with particles useful additives or interfere with the precipitation of the desired water-insoluble mineral supplements on the skin.

The authors of this application has unexpectedly found that if a useful additive is delivered in the form of activating powder comprising (1) a useful Supplement; (2) water-soluble (or at least partially soluble) carrier; (3) water and (4) optional adjuvant that promotes deposition/facilitation process selected from the group consisting of the emer, Merquat100) and hydrophilic polymers (such as polyethylene glycols of higher molecular weight), it is possible to enhance the deposition of mineral supplements (which approximates to the same high level as when using shower gels instead of bars), while not damaging technology (and in some cases increasing it), and without reducing consumer qualities such as volume of foam.

The use of some precipitating polymers (for example, cationic polymers to enhance deposition of water-insoluble particles (e.g., softening oils such as silicone oil), known for the deposition of substances from a liquid shampoos on the hair. For example, in U.S. patent 5037818, reported that cationic compounds enhance the deposition of particles on the hair from shampoos.

In the publication WO 94/03152 (transferred to a public company with limited liability Unilever) reported liquid detergents, which can effectively besiege silicone oil on the skin with cationic polymers.

In U.S. patent 4788006 (Bolich, Jr. et al.) reported shampoos with particles of silicone oils ranging in size from 2 to 50 micrometers, compositions which contain KSA is about, about the deposition of useful additives of the detergent bars. In addition, they are not reported and there are no powdery adjuvants, including useful Supplement plus a special media that can withstand spray drying (and optional auxiliary means of facilitating deposition of facilitating technological processing, which may include cationic polymers); in these publications also not reported and are not offered the use of such powder adjuvants together with chips for the manufacture of detergent bars.

In the art also describes detergent bars for personal use, including cationic polymer to ensure the effect of conditioning the skin and/or soft (see U.S. patent 4673525, 4820447 and 5096608). In these references, the cationic polymer is used in combination with a useful Supplement for the education obtained by the spray drying method of activating powder, as described in the present invention.

In U.S. patent 3761418 describes detergent compositions containing water-insoluble substance in the form of particles and cationic polymers to enhance the deposition and retention of particles Weeden antimicrobial substances from bars of soap by using cationic polymers. But the document does not describe or offer the use of activating powder of the present invention (which should contain the media and do not necessarily include cationic polymer) to improve the deposition of useful substances.

Made by the authors of this application and at the same time a pending application for U.S. patent 08/821504, filed same date as this application and entitled "Method for improving deposition of bars, including the use of the compositions activating powders, including useful Supplement and precipitating the polymer, the authors reported the bars made from activating powder, which comprises a cationic polymer. Activating a substance according to the present invention is not limited to the fact that they contain media with a melting point above 80oWith, preferably above 100oSince this application has a broader purpose and its concept is to first create the activating powders containing useful additive (as well as containing cationic substances that promote deposition), and then subjected to co-extrusion with chips, and you can use any process (free suslow melting point it can withstand spray drying.

The invention relates to compositions for washing bars, in which from 1 to 30% (by weight) of the powder composition, preferably from 5 to 25%, more preferably from 10 to 25 percent of the powder composition is mixed from 99 to 70%, preferably from 95 to 75%, "normal" chips for detergent bars comprising from 5 to 90% of the complex (system) surfactants. The composition of the activating powder and shavings are mixed and ekstragiruyut, getting in the composition for bars, capable of delivering a useful Supplement to the skin in concentrations much higher than previously possible concentration.

In particular, the invention relates to compositions for bars, including:

(A) from about 1% to 30% of the powder (which is about 10% of the content), including:

(a) from 1 to 70% potassium (from weight of powder);

(b) from 15 to 98% of the media (by weight of the powder);

(C) from 1 to 10% water (by weight of the powder);

(d) from 0 to 30% subsidiary means for the deposition/ease of processing (for example, surfactants, cationic polymer and/or hydrophilic polymer) (by weight of the powder) and

(B) from 99 to 70% of the chip, comprising from 5 to 90% of the complex (system) surface the gene surfactants, nonionic surfactants, amphoteric surfactants, cationogenic surfactants and mixtures thereof.

The amount of filling a useful additive in finally made the bars (e.g., about 10%) depends on how many percent of the powder is useful additive. For example, if the powder contains 50% oil as useful supplements, you will need 20% of the powder (and 80% of the chip) to get 10% filling (i.e., 50% from 20%). If the useful substance is only 25% of the weight of the powder, in order to get 10% content in the finished bars will require 40% of the powder (25% of 40%) mixed with 60% of the chips.

In another embodiment of the invention the present invention relates to a method of manufacture of detergent bars, in which (a) and (B) receive separately; in which (a), (b), (C) and the optimal number (g) is mixed at a temperature of from 40 to 80oWith; in which the mixture (a) and (b) is subjected to spray drying at a temperature of from 80 to 200oC at a pressure of from 0.10 to 0.30 MPa, and in which (a) and (B) are blended, passed through the screw machine and ekstragiruyut, getting ready bars.

The present invention Casa is whether other substrates, than was previously possible for the compositions of detergent bars. In particular, by obtaining activating powders containing the desired mineral supplements, and co-extruding powder containing useful Supplement to "normal" chips containing surface-active substances, you can get bars that deliver relatively large amounts of useful additives to the skin.

Thus, the invention relates to powders containing useful additive having a specific new composition (i.e., useful additive is generally added in the form of an emulsion; as a rule, water-soluble carrier and optional auxiliary tool for deposition/facilitate processing), and also relates to detergent bars, obtained by joint extrusion of these activating powders and containing surfactants "normal" chips.

Each component is described in more detail below.

THE COMPOSITION IS USEFUL SUPPLEMENTS

Composition useful additives of the present invention may be a useful component of the additive, or it may be a useful additive is added by using media. In addition, the composition is useful additive may be a mixture of two or more compounds, one or all of which may have useful properties. In addition, a useful Supplement by itself can act as a carrier for other components that can be added to the composition for detergent bars.

Useful additive can be an "emollient oil", by which is meant a substance that softens the skin (keratinized layer) by increasing the content of water in it and keep it in the soft state by slowing down the process of reducing the moisture content.

As mentioned above, if useful Supplement is 50% by weight of the powder, and the powder is 20% of the mixture of powder and chips, which ekstragiruyut to produce the final product - bars (i.e., 20% powder/80% of the chip), then content useful additive is 10%.

MEDIA

In one of the embodiments of the invention, the component carrier may be any water-soluble starch, including partially soluble starches (such as corn or potato starch), and, more preferably, "true" rest terauda with the formation of transparent or essentially transparent solution. Examples of such starches include maltodextrin. Maltodextrin is particularly preferred.

In another embodiment of the invention the carrier may be a water-soluble solid non-crystalline substance, such as, for example, casein alkali metal (e.g. sodium Caseinate).

The media can also be a semi-crystalline, water-soluble solid, such as, for example, gelatin.

The media according to the present invention must have a melting point above 80oWith, preferably above 100oC. it Is believed that carriers with such a high melting temperature can successfully withstand spray drying in the production of powder, without the formation of insoluble mixture. Keep in mind that you can use and the media with a lower melting temperature (theoretically not higher than room temperature), if they are obtained using the full (rather than laboratory) spray dryers. Thus, all that is required is that the melting temperature of the medium was higher than the temperature of the drying chamber, in which the activating additive.

SOEDINENIYa

The third component of the composition of the powder - water, which typically is from about 1 to about 10% of the quantity of powder. It should be noted that for some materials is not necessary such a low water content, and, if necessary, add some water (for example, to improve the fluidity of the powder), since in any case the powder is hygroscopic.

SUBSIDIARY MEANS FOR THE DEPOSITION/FACILITATE

PROCESS

An optional component of the powder composition is an aid to sedimentation/facilitate processing, which is selected from the group consisting of (1) anionic, cationogenic, nonionic and amphoteric surfactants; (2) cationic polymers, and (3) hydrophilic polymers.

Surface-active excipients group (1) can be one of the tens of suitable surface-active substances, including the following, but not limited to: sulfates Olkiluoto ether; alkylalkoxysilane; alkylalkoxysilane; sulfonates alkylglycerol ether; sulfonates, alpha-olefin; acultural; methylcytosine; N-acercate; sulfates of ethoxylated alkyl; alkylpolyglucoside; alkylamine oxides; betaines; Sultana; alkylsulfonate, diallylmalonate, allactivity and mixtures thereof.

The above components may be from about 0 to 30%, preferably from 0 to 15% of the composition of the powder.

GETTING

Powder adjuvants according to the present invention, typically, although not necessarily, get through the preparation of a mixture of mineral supplements (usually in the form of an emulsion), water-soluble media (e.g., maltodextrin) and optional excipients for deposition and facilitate processing, to form a suspension.

As mentioned, mineral supplements, as a rule, include in suspension in the form of emulsions. These emulsions or supplied, or they can be prepared in the laboratory, depending on the availability of interest useful additives. For example, the silicone can easily be purchased at Dowand emulsion of mineral wt is oligator, and the rest is water.

The media are usually obtained in the form of a solution and, as a rule, it is preferable to add an aid to sedimentation/facilitate the process (if used) to this solution media. For example, the starch can be prepared in the form of a solution, usually containing an auxiliary agent for deposition/facilitate processing. In particular, maltodextrin, for example, can be prepared in the form of a 50% aqueous solution, which is supported at 60-70oWith stirring using installed through the top of the agitator, and to this solution maltodextrine, you can add an auxiliary agent for deposition/facilitate processing, if it is used.

Typically, the emulsion is useful additive and solution media and tools for deposition/facilitate processing mixed, diluted so that the water content was about 70%, and heated to approximately 70oC. it Should be noted that dilution is used only in order to ensure a sufficiently low viscosity, which would transfer pump on a laboratory scale. For large scale work, the Oia is then pumped into the device for drying, for example, in a spray dryer.

If using spray dryer, the suspension is pumped into the pipe, and the nozzle pipe may have a temperature of 80 - 200oWith, preferably 100 to 200oC. At the end of the nozzle, the slurry is subjected to a fine spray using parallel air flow and high pressure. As a consequence, the water evaporates and remains free-flowing powder, which captures useful Supplement.

Thus, as a rule, obtaining powder involves mixing the carrier and mineral supplements at 40 - 80oWith, preferably 50 - 70oWith the passing of the mixture through a spray dryer with a temperature of the nozzle 80 - 200oWith, preferably 100 to 200oC, at a pressure of 0,10-0,30 MPa and unloading of the obtained powder.

A typical ready activator contains 0 to 30% subsidiary means for the deposition/facilitate processing, 1 - 70% mineral supplements, 30 - 98% medium, and 1 to 10% water.

The finished powder is then injected into bars, which initially mix it with chips in amalgamator. Then activating powder and shavings for detergents personal use ekstragiruyut, receiving the workpiece, using a standard about the ability to be precipitated mineral supplements compared with those bars, in the manufacture of which is useful additive is introduced directly into bars during the stage of mixing.

CHIPS SURFACTANTS

As mentioned, in the finished bars contains 1 to 30% of adjuvants. The rest of the ingredients forming the final composition of the bars (i.e., from about 99 to 70% of the chips include chips, which usually includes a set (system) of surface-active substances, which constitute the main part of the cleansing bar.

In particular, the chips with complex surfactants comprise from about 5 to 90 wt.% complex surfactant, which surfactant is chosen from the group consisting of Soaps (including surfactants, consisting only of soap), anionic surfactants, nonionic surfactants, amphoteric/zwitterionic surfactants, cationogenic surfactants and mixtures thereof. This chip can optionally contain other components, which are usually contained in the finished composition for detergent bars, for example, trace amounts of flavorings, preservatives, polim the

P the aqueous fat, or mixtures thereof, as these fats are among the most affordable. The content of fatty acids having at least 12 carbon atoms in the soap of coconut oil is about 85%. This value will be higher if you use a mixture of coconut oil and fats such as solid animal fat, palm oil or butter or fats from non-tropical species of nuts, in which the length of the main chain fatty acids is C16and above. The preferred soap for use in the compositions of the present invention contains at least about 85% fatty acids having from about 12 to 18 carbon atoms.

Coconut oil used for making soap, can be completely or completely replace other attractive kinds of oils, i.e. such oils or fats, in which at least 50% of total fatty acids presents lauric or myristic acids and mixtures thereof. These oils are usually cited as examples of oils from tropical species of nuts belonging to the class of coconut oil. For example, they include palm kernel oil, oil of Brazilian babassu nut oil from ouricuri, touchmove oil, oil from nuts of the palm ivory, oil from murumuru, oil alnoe soap is a mixture of from about 15% to 20% coconut oil and from about 80 to about 85% of solid animal fat. These mixtures contain about 95% of fatty acids having from about 12 to about 18 carbon atoms. Soap can be made from coconut oil, and in this case, the content of fatty acids is about 85% when the length of the chain WITH12-C18.

(1) 1.8 kg chip Dove (brand) and 0.45 kg of spray dried powder is mixed in the dry state or in quite the well mark Weber-Selander, which after the first stage receive the product in the form of noodles, and the second stage receives the workpiece.

(3) the Workpiece is cut into pieces of such length that corresponds to the matrix for bars in the press, and use them for stamping block.

Received block contains approximately 9.3 percent (60000 mPas-1) poly(dimethylsiloxane).

Trial deposition in vitro

Samples processed as follows: the bars 10 times rubbed on a piece of wet pigskin size 25 cm2then within 30 seconds froth formed liquid, and then the skin is rinsed for 10 seconds in water with a temperature of 36.3-39,4o(90-95oF). Then processed pig skin is placed in a flask and carry out the extraction of silicone with 10 ml of xylene. Then the skin is removed from the flask and used for the extraction solvent to analyze the content of the silicone using inductively-coupled (Inductively Coupled plasma emission spectroscopy.

The deposition of silicone on the pig skin is comparable with the results obtained using shower gels.
