Abstract

In order to provide a process for producing a composition which is compatible in an application for cosmetic or cleaning purposes and is soluble to give a clear solution together with most of the cosmetic raw materials used and has good processability, and which, moreover, has the necessary properties without or with a relatively small addition of silicone compounds or oleochemicals, and which imparts a soft hand, especially to human or animal hair, as a result of which the hairs thus have low stiffness and roughness, and which also drastically lowers the material costs of the compositions, it is proposed that at least one starch and at least one polygalactomannan be cationized together.

Description

A process for preparing a composition comprising cat ionized starch and cationized polygalactomannan

description

The present invention relates to a process for the preparation of a composition, characterized in that at least one starch and at least one polygalactomannan are cationized together. The present invention further relates to the compositions and preparations containing such compositions. The compositions of the invention are, in particular, personal care products, household care products, pet care products and preparations for treating yarns, fibers, textiles, including nonwovens, paper and board. The invention further relates to the use of the above-mentioned compositions.

State of the art

The surface properties of the skin and hair are of particular interest in cosmetics, and it has always been of interest to develop cosmetic compositions which moisturize and favorably affect the surface and the keratin scaffold. This often happens because the water absorption capacity of the upper skin and keratin layer is improved. Suitable substances for this purpose must have adhesive properties.

Human and animal hairs consist of keratin, a sulfur-containing fibrillar protein with an isoelectric point between pH 3.2 and 4. Thus, the hair present in most care products has negative charge. Synthetic, cationic polymers, for example, have long been used as such or as additives in conditioners and shampoos to improve the combability of wet or dry hair. The affinity of cationic polymers to negatively charged hair leads to a film formation, which hampers the knotting of the hair and reduces hair sticking by static charge when combing.

Quaternary nitrogen-containing copolymers of inylpyrrolidone and dimethylaminoethyl methacrylate, Polyquaternium-7, (according to chemical identification = poly (diallyldimethylammonium chlorides-N, N-dimethyl-N-2-allyl chloride polymer with 2-acrylamide In the foreground are currently again the problems with polyacrylamide-based petrochemical Polyquaternium-7, which binds due to the high cationic activity color and dirt constituents from the wash liquor and especially on light laundry (eg towels) precipitated and discolored. 7 Contains, as an impurity, residual amounts of poisonous and contemplated acrylamide, not to speak of the environmentally harmful aspects In contrast, the products according to the invention are based on natural substances, which signify a significant advantage.

In shower, bath and liquid soap products, the film formation on the skin caused by cationic additives is used to fix active ingredients on the skin, to improve the sensory profile of the skin, to prevent the skin from drying out, and to add flavor to the skin through affinity place.

However, silicone additives and other synthetic agents, which until now have generally been required in addition, are becoming increasingly less accepted by consumers. The trend in the industry is therefore towards natural resources.

A partial solution, the replacement of synthetic with natural substances, has already been achieved by the technology of EP 1 051 967 A2 as a first step. From this it is known to use in cosmetic preparations a cationic starch for the above-mentioned tasks. Preferably, this is in liquid form, so easy to use before. In 2004, these preparations were launched by Gräfe Chemie GmbH under the trade name AMYLOMER and have meanwhile successfully established themselves worldwide. The results on skin and Although hair is excellent, the effect should be improved and thus the dosage reduced, in order to reduce the influence of such preparations on other properties of the products and to improve the economy.

1988 USP 4,753,659 discloses the production of cationic guar and cationic cassia. The use of cationic guar gum has been widely discussed in the patent literature, there are 435 results. Representative here is the most important US patent 6 365 140 from 2002 called. It concerns cationic guar which has been well-known in the cosmetics industry for years under the trade marks JAGUAR C-17 and JAGUAR C-15 of the manufacturer HERCULES. It is a powder product. A major disadvantage of powder products is that they have to be dusted in the production of cosmetic products undesirably strong and must be brought into solution by means of a complex process. In addition, guar has multiplied as a raw material in price extremely, because guar gum is now by the fracking technology of natural gas extraction from slate is highly scarred.

The use of cationic cassia flour is relatively new. As an example, it is described in US patent application 7 923 422 from the year 2011 entitled "Cassia derivatives and application therefore." This cationic cassia flour has recently become commercially available under the brand name SENSOMER from LUBRIZOL a powder product.

However, a major disadvantage of cationic guar gum and cationic cassia flour is that the hair has a hard and inflexible feel, that is, it appears hard and stiff. The conditioning of hair with cationic guar gum or Cassiamehl alone produces a well-improved combing behavior, both wet and dry hair and also an antistatic effect. However, the achievable effects no longer meet the demands of the cosmetics industry in terms of wet and dry hair and their sensory properties. It is also imperative to additionally use silicone oil, silicone products or other fatty substances in all of these guar and cassia formulations in order to counteract the roughness. Silicones (dimethicones) are but Nowadays more and more undesirable, unfortunately, with these two basic substances unconditional condition to counteract the adverse effects.

Object of the invention

The novel compositions had to be compatible, clearly soluble with most of the cosmetic ingredients used, and easy to process. You should have the necessary properties with no or less addition of silicone compounds or fatty substances, in particular, they should give hair a softy handle, so the hair should have low stiffness and roughness. In addition, they should drastically reduce the material cost of the compositions over the prior art.

Yarns, fibers, textiles, including nonwovens, paper and paperboard are said to impart desirable surface properties such as grease impermeability and the like to the compositions of this invention.

The novel compositions should be made available in a user-friendly liquid form as far as possible.

Description of the invention

The present invention relates to a process for the preparation of a composition, characterized in that at least one starch and at least one polygalactomannan are cationized together, wherein the feature according to which the cationization is carried out together is a particular feature of the process according to the invention. The fact that starch and polygalactomannan are collectively subjected to a cationization process results in a composition having completely new and improved properties which exhibit synergistic effects as compared to the separately cationized polymers. As starting materials for the process according to the invention are inexpensive natural polymers, which are inexpensive renewable resources and are biodegradable. This is not only consumer friendly, but also commercially advantageous. The compositions and their effects are described in more detail below. Without wishing to be limited to a particular mode of action of the method according to the invention, it is assumed that complex formation of the helix structures of the polymers is achieved by the method according to the invention, which could be the cause of the synergistic properties of the compositions according to the invention.

The terms "polygalactomannan" and "galactomannan" are used in the literature for the same group of compounds. In this text the term "polygalactomannan" is used, which is interchangeable with "galactomannan". Furthermore, in the context of the present invention, the term "starch" is intended to encompass all polysaccharides in the most generalized form. Within the scope of the present invention, starch is defined as all polysaccharides produced in nature, in particular all starch-containing products, especially root tubers The starch used in the method according to the invention is selected from the group consisting of natural, ie native starch, and modified starch The use of natural starch is preferred and this is preferably selected from the group consisting of corn starch, rice starch, The use of modified starch is likewise preferred and is preferably selected from the group consisting of partially degraded starch, ie partially molecular depolymerized starch, esterified Starch, etherified starch, crosslinked starch, graft modified starch and starch containing several of these modifications.

The polygalactomannans used in the process according to the invention are to be understood as meaning all vegetable hydrocolloids which have galactose and mannose units. Polygalactomannans selected from the group consisting of natural polygalactomannans and modified polygalactomannans are used in the present invention. The use of natural or also referred to as "native" Polygalactomannanen, ie of natural origin, is preferably, and these are preferably selected from the group consisting of guar gum, locust bean gum, cassia, konjac and taragum. Juarkernmehl is particularly preferred. Cassia is also very much preferred. The use of modified polygalactomannans is likewise preferred and this is preferably selected from the group consisting of partially degraded, ie partially molecular depolymerized, polygalactomannans, esterified polygalactomannans, etherified polygalactomannans, graft-modified polygalactomannans and polygalactomannans containing several of these modifications. Especially preferred are hydroxypropylated polygalactomannans.

Methods for modifying and cationizing starches and polygalactomannans are well known to those skilled in the art. For example, the aforementioned document US 4,753,659 discloses a method of making modified Cassia Tora. These methods can generally be used to separately prepare cationic starches and cationic polygalactomannans. But a common cationization to form a composition of the type according to the invention is not provided there.

Particularly preferred is a method of the invention wherein the at least one starch and the at least one polygalactomannan are reacted together with one or more compounds covalently linking one or more groups selected from the group consisting of ammonium groups, sulfonium groups and phosphonium groups to the starch molecule or the polygalactomannan molecule wherein the feature according to which the reaction of the at least one starch and the at least one polygalactomannan is carried out together again represents a particular feature of the preferred embodiment of the process according to the invention. The groups can be connected only to the starch molecule or only to the polygalactomannan molecule or both.

Also preferred is a process according to the invention, wherein the at least one starch and the at least one polygalactomannan are reacted together with a compound from the group of the polyamines or a compound of the structure AR wherein R is selected from the group consisting of -N (R ³ ) ₃ ⁺ X ^- , -S (R ³ ) 2 ⁺ X ^" , and -P (R ³ ) ₃ ⁺ X ^" wherein R ^{3 is} independently substituted or unsubstituted, linear or cyclic alkyl groups having 1 to 24, preferably 3 to 10, and more preferably having 1, 2 or 3 carbon atoms or substituted or unsubstituted phenyl groups and X ^{"may be} any suitable counterion and wherein A is an alkylene group having 1 to 24 , preferably 3 to 10 and particularly preferably of 3 carbon atoms, which is provided at least with a functional group which is suitable to connect A to the oxygen atom of a free hydroxyl group of the at least one starch and / or the at least one polygalactomannan and wherein the groups R ^{3 may be joined to} one another or to ring A, whereby the ring thus formed may also have additional heteroatoms If R ³ or R ³ and A are connected to one another, it is natural Of each substituent at the point of attachment, one hydrogen atom is replaced by the bond.

The compounds of the formula A-R are preferably selected from the group consisting of 3-chloro-2-hydroxypropyltrimethylammonium halides and 2,3-epoxypropyltrimethylammonium halides. These are particularly preferably selected from the group consisting of 3-chloro-2-hydroxypropyltrimethylammonium chloride, 3-chloro-2-hydroxypropyltrimethylammonium bromide, 2,3-epoxypropyltrimethylammonium chloride and 2,3-epoxypropyltrimethylammonium bromide. A suitable method for cationizing starches and polygalactomannans is described in Example 4 of this document.

The degree of substitution (DS) of the product obtained is preferably chosen such that a biodegradability of the final product is still ensured. The person skilled in the art can test the biodegradability according to known methods.

In preferred processes according to the invention, the total amount of the polygalactomannans used is 30% by weight or less, preferably 5% by weight or less and particularly preferably 0.001 to 3% by weight, based on the dry mass of the starch used. That already the use of such small quantities Polygalactomannan leads to effective compositions, is surprising and advantageous because starch is usually much cheaper than polygalactomannans.

Example of production

The prepared or prepared inventive product is prepared by subjecting native and / or degraded starch and / or otherwise modified starch together with the described polygalactomannans and in the powder form to a cationization process. Starch and polygalactomannans both have molecular helical structures. In the cationization process carried out jointly in accordance with the invention, the helix structures of the starch and of the polygalactomannans intermesh molecularly into one another; a complex formation takes place via the helix structures. Cosmetic preparations prepared according to the invention using such compositions have a structure-improving, gloss-improving, volume-forming and skin-smoothing action on the skin and / or hair. The activation of the fibrillar collagens and fiber proteins of the hair could be fundamentally reshaped by the compositions according to the invention. This gives hair an optimized and desirable feel as well as fullness. Since this effect clearly exceeds the cumulative effects of a simple combination of previously known substances, it is also possible here to speak of synergistic properties. The resulting product is therefore also referred to as a synergate. A synergism in this meaning of the term is rewritten as the result of the interplay of two or more substances that promote each other to give a resulting greater common benefit, thereby potentiating the effects of individual substances.

Although processes for dry cationization are known in principle, they are only used in individual components. The digestion and thus bringing into an aqueous solution takes place with or without molecular breakage of the polymeric structure and / or by molecular restructuring or by oxidizing and / or by the action of weak to strong acids or their salts or by means of enzymes and / or by the action of elevated temperatures. The inventive method is thus preferably carried out in solution and more preferably in aqueous solution, preferably in such a concentration that the reaction product can be used directly without further workup. However, preference is also given to a process according to the invention in which, after completion of the reaction, the water and optionally all other liquids are removed by evaporation, optionally under reduced pressure, in order to obtain a pulverulent product.

Another object of the present invention relates to a composition prepared by a method according to the invention, as described in this document. The composition of the invention is preferably a liquid composition. This eliminates the energy-intensive and procedurally difficult drying step. From the handling of a dusty and / or tending to clumping powder during further processing can also be waived. The liquid form has already been described in detail in EP 1 051 967. However, a powdery composition is also part of the present invention. The composition of the present invention preferably contains water, more preferably, it is preferable to use water as the solvent, and it is most preferable to use water as the sole solvent. It is further preferred if the composition according to the invention contains no silicone oils or other silicone-containing substances. It is also preferred if it contains no fatty substances. The composition according to the invention gives preparations prepared therefrom advantageous properties, including those as described in this document in connection with the respective preparations. In particular, it gives various substrates advantageous surface properties. It has all the properties described here, even independently of the association with other ingredients or the processing into preparations.

Another object of the present invention relates to a preparation comprising or prepared using a composition according to the invention as described in this document, which was prepared according to the method described in this document. It is preferable if the Composition according to the invention contains no silicone oils or other silicone-containing substances. It is also preferred if it contains no fatty substances. As described above, such a formulation is capable of imparting surface properties to various substrates.

The preparation according to the invention is preferably selected from the group consisting of cosmetic preparations, i. Personal care products, household care products, pet care products and preparations for the treatment of yarns, fibers, textiles, including nonwovens, paper and cardboard. The novel compositions of the invention impart desirable surface properties to hair, skin, yarns, fibers, fabrics, including nonwovens, paper and paperboard.

The preparations according to the invention are preferably personal care products. These may be "rinse-off" products such as shampoo, conditioner, shower bath, bathing product, liquid soap or leave-on product, e.g. Hair fixator, conditioner, cream or lotions, etc., act. In this case, it is particularly preferred for the preparation according to the invention to contain the compositions according to the invention in an amount in the range from 0.01 to 10% by weight of dry mass of the jointly cationized starches and polygalactomannans contained in the composition, based on the finished product.

The preparation according to the invention is particularly preferably a cosmetic preparation. It has been found that the compositions according to the invention contain, as a cosmetically active ingredient, compositions comprising starch and polygalactomannans, in particular cationic starch and cationic polygalactomannans. As already stated above, the cosmetic preparations according to the invention have a structure-improving, gloss-improving, volume-forming and skin-smoothing action on the skin and / or hair. The activation of the fibrillar collagens and fiber proteins of the hair could be fundamentally reshaped by the compositions according to the invention. This gives hair an optimized and desirable feel as well as fullness. The cosmetic preparation is preferably selected from the group consisting of cosmetic washing active formulations, hair colorants, sunscreen creams, lotions, moisturizers, hair fixatives and conditioners. Preferred among the detergent-active formulations are those selected from the group consisting of shampoo, conditioner, bath product, shower product and liquid soap.

It has been found that excellent affinity of the indicated starch structures results in negatively charged hairs and negatively charged skin, which is reflected by a reduction in the amount to be used in a cosmetic wash active formulation, especially shampoo or bath products, and remarkably improved film formation. This is also attributed to the stability-improving nonionic, anionic or cationic groups of the modified starch. In this way, a higher affinity to the protein structures given above, because they bind adsorptively to this creates. Due to the cationic character of the compositions of the present invention and the fact that they additionally form C: O-H-O covalent hydroxyl group bonds, the starch polygalactomannan derivatives are capable of affording other skin and hair formulation ingredients as affinate fix in order to avoid premature washing out. In the context of the present invention, the term affinate denotes a substance bound by affinity, in particular reaction affinity. In particular, an affinate is the result of affinity between two or more molecules, where the molecules unite, interact, and occur as a whole. In this fixation, there is a significant difference to conventional cationic starches or to conventional cationic Polygalactomannanen. This is particularly true for hair dyes and is particularly important for products such as sunscreens, cream in general and moisturizers whose action on the skin, hair and in the upper layers to drain. The addition of silicones and / or fatty substances can be completely or at least partially eliminated for the reasons mentioned above. This is an additional big advantage. It is preferred if the cosmetic preparation is an anionically structured shampoo or personal care product and the preparation according to the invention is well tolerated. The cosmetic medium used is particularly preferably an anionic shampoo or personal care product.

For example, the cosmetic preparation is a surface-active substance-containing anionic shampoo or shower product, to which the cationized composition according to the invention imparts increased film-forming and nourishing properties at a lower level of use than with corresponding known products.

Hair coloring formulations formulated with the cationic liquid starch polygalactomannan compositions provide increased affinity of the hair coloring ingredients to the hair, provide higher and more uniform color yield and result in a discharge of the waste water by residual dyes.

Preference is given to a cosmetic preparation comprising a composition according to the invention in an amount of from 0.01 to 5% by weight, preferably 0.1 to 0.5% by dry weight of the jointly cationized starches contained in the composition and polygalactomannans based on the finished product , Thus, in a cosmetic wash active formulation such as shampoo or bath products, the amount of conventional cationic starch can be from about 2% to 0.1% to 0.5% dry weight of the co-cationized starches and polygalactomannans contained in the composition relative to the finished product be lowered.

Advantageously, one or more surfactants known per se for use in cosmetic preparations are added to the cosmetic preparations according to the invention. Preferably, the cosmetic preparations according to the invention as described herein additionally contain from 2 to 60% by weight of an anionic surfactant or co-surfactant, from 0.5 to 30% by weight of a nonionic surfactant or co-surfactant, 0.25 to 20% by weight of an amphoteric surfactant, based on the finished product. Preferred surfactants are sodium lauryl sulfate, sodium laureth sulfate, glycereth-2-cocoate, glycol distearate, ammonium lauryl sulfate, ammonium laureth sulfate, cocamide MEA, sodium lauroyl methyl isethionate, cocamidopropyl betaine, sodium laureth sulfosuccinate, cocamidopropyl betaine, Sodium Lauryl Sulfoacetate, Coco Glucoside, Lauryl Glucoside, Cocamidopropyl Betaine, Glyceryl Laurate, Disodium Cocoamphodiacetate or Acyl Glutamate.

Optionally, in the novel preparation according to the invention, an addition of hair- and skin-friendly and / or moisture-regulating substances can take place, which interact with the aqueous starch or optionally stabilize it. In this sense, suitable additives are, for example, glycerol and glycerol compounds, polyalcohols, sugar alcohols, glucose and fructose syrups, as well as various fruit acids, alpha-hydroxy acids or their salts, as well as urea and modifications thereof. Also, additional crosslinks of a chemical nature, with reagents known per se to those skilled in the art for that purpose, or crosslinks of a physical nature with minute amounts of aluminum salts and / or borax are possible.

The cosmetic compositions according to the invention may further contain cosmetically acceptable preservatives, such as sodium benzoate, as well as the preservatives mentioned in official approval lists, in particular the so-called INCI list. In addition, preservative-free formulations with additives that are not subject to declarations are possible (alcohol derivatives). Benzoic acid, sodium benzoates, isothiazolinones, salicylic acid, sorbic acid, triclosan, parabens, phenoxyethanol, bronopol, anisic acid or levulinic acid can be used as customary preservatives.

The enumerated benefits in cosmetic formulations are also related to use in products for the treatment of animal hair as well as processed hides for washing, grooming and cleaning. It has been found that at much lower dosages not only equal but potentiated effects are achieved than with the cationic starch product alone or the cationic guar or cassia products alone. For this purpose, the achievable economic advantages are listed in the following example:

Product dosing price /

Cost of money performance ratio

AMYLOMER 6.00 1.15% 6.9

NEW PRODUCT 8.00 0.4% 3.2

CATIONIC GUAR 33,00 0,2% 6,6

Product costs are understood as the normal market price in EURO per 1 kg. The average dosage comes from the practical application quantities. The price / performance ratio is calculated from the product cost in kg multiplied by the average dosing quantity.

It becomes clear how strongly the price / performance ratio could be optimized.

Due to the high substantivity creates a lesser film on the hair. As a result, there is no structure of the active ingredients, because they are washed out the next wash and then placed again in place. In addition, there are the qualitative advantages that are described in detail elsewhere in this document.

Preferably, the modified starch in the form of a liquid product is added directly during the preparation of the cosmetic preparation. The increased cost of producing the ready-to-use liquid modified starch is compensated for in straightforward application and by a constant quality adjustment. This is the simplest and most economical application practice. However, the products can also be suitably dried, in dry form Dry products are added or brought into solution again before use. But that does not seem so preferable for practical and cost reasons.

In the following, some test results are reproduced with the compositions according to the invention for further illustration. The product according to the invention (synergate) is called SYNERGATE in the test series.

Described is initially a test procedure for evaluating the effect of a cosmetic composition made, which in the following tables the name "Synergate VP 13-01-12" carries, which has been tested in several surfactant cosmetic formulations for hair and body care.

First, preliminary experiments served to identify incompatibilities with differently formulated, marketable surfactant solutions manufactured by Color & Care Consulting, Wiesbaden. Turbidity was tolerated, but precipitations were not tolerated.

A second step of the preliminary tests was carried out to set upper and lower limits for a use concentration of the composition "Synergate VP 13-01-12" and the associated desired efficacy as a hair care washing / showering / bathing product with nourishing or lasting improvement of the skin feel to determine after the application.

With the surfactant cosmetic formulations provided for the preliminary tests, no precipitations could be visually observed even at an elevated concentration of 1.5% in the product.

These surfactant cosmetic formulations were used to prepare test specimens with concentrations of 0.1 / 0.5 / 1.0 and 1.5% "Synergate VP 13-01-12." These product samples were initially used in the context of hair washing tests for combing force measurements and combing force evaluations with the products washed hair and the assessment of the hair grip, ie the sensory feeling of the hair used. As a material to be washed bleached strands of hair, about 1.5 cm wide 23 cm long. Weight approx. 1.5 g.

The following test steps for combing force measurement were carried out:

1.) Cold wash with lml shampoo + 0.25% Synergate VP 13-01-12 / 60 sec. rinse with cold water / 30 sec. prepare with Synergate Shampoo / 15 sec.

2.) cold wash / 60 sec. rinse with cold water / 30 sec. prepare with Synergate Shampoo / 15 sec.

3.) cold wash / 60 sec. rinse with cold water / 30 sec. prepare with Synergate Shampoo / 15 sec.

4. Cold wash / 60 sec. rinse with cold water / 30 sec. prepare with Synergate Shampoo / 15 sec.

5.) cold wash / 60 sec. rinse with cold water / 30 sec. prepare with Synergate Shampoo / 15 sec.

After the fifth wash, the wet combability was evaluated and after Föntrocknung also the dry combability.

The five washes are required to achieve a relatively even film formation on the hair. As an example, the results for two of these formulations are listed. The first line of the table lists the different concentrations used in the relevant, tested example of the composition according to the invention, including the results obtained from hair washing experiments.

In a comparable manner, the formulations described above containing the composition according to the invention "Synergate VP 13-01-12" were subjected to skin tolerance tests, skin film evaluation or skin feeling.

To evaluate the feel of the skin, forearm washes were mostly used to wash the inner forearm areas with 1ml Shower Gel 3x and handwarm water, washing one forearm side without Synergate VP 13-01-12 and comparing them.

After washing and drying the skin by means of a textile towel, a subjective assessment of the changed skin feel of the dry skin was made. The evaluation was carried out on the basis of that of the hair washing experiments.

Preference is likewise given to a preparation according to the invention as described above, which is a finishing liquor or a fabric softener for the treatment of yarns, textiles and nonwovens. In the field of textiles and nonwovens - the latter are not woven and are therefore also referred to as nonwoven - the compositions according to the invention are used to give yarns, twisted or woven textiles and nonwoven fabrics increased strengths and a stronger, ie. give it a fluffier-fuller feel and still achieve volume and anti-static. A classic fabric softener added in an amount of 0.3 to 5%, surprisingly results in addition to the soft effect a fuller feel of the textile and the composition of the invention contributes overall to the structural improvement. Renewable resources for this purpose is also a significant advantage of the present invention. The composition according to the invention is preferably used in such formulations in an amount of from 0.3 to 5% by weight of dry matter of the jointly cationized starches contained in the composition and polygalactomannans based on the finished product.
