The SCOPE TO WHICH the INVENTION RELATES

The present invention relates to a soft detergent compositions which have desirable performance properties, such as foaming tendency, provide excellent moisturizing and conditioning benefits to hair and skin, and is stable when stored.

The LEVEL of TECHNOLOGY

Detergent compositions, soft hair and skin and is perceived as providing sensory characteristics that consumers associate with a healthy moisturized hair and skin, in recent years become increasingly popular.

Although as the basis of such detergent compositions have been proposed various systems soft surface-active substances, as a rule, there is a contradiction between the softness of the composition and its ability to create rich foam. Consequently, the application of mild surfactants, those who develops recipes, often increase the total content of surfactants in order to overcome the lack of foam. This not only adversely affect the economy of composition, but also can reduce the softness of the composition, because the ability of the surfactant to interact with proteins present in the hair and skin, is dependent, among other factors, of the total concentration over OSTO-active substances. In addition, high concentrations of surfactants may also hamper the effective delivery of insoluble means for conditioning hair and skin which it is desirable to include in the moisturizing composition of shampoos.

Thus, a need remains in the compositions of surfactants, soft hair and skin, but, nevertheless, effective from the point of view of creating rich, rich foam without having to use excessive levels of surfactants in the composition, and is very compatible with insoluble conditioning means for the hair.

In the study of a variety of soft detergent compositions it was found that the dual of a mixture of certain alkylalkoxysilane and amphoteric surfactants, used alone or in further combination with alkylalkoxysilane and other surface-active substances, can create a very effective and soft base for shampoos and detergents for washing skin. However, had highly variable and unpredictable stability during storage. Some combinations became very viscous, even saludable during storage and were unacceptable to consumers, while others with the fact that, apparently, was of the same nominal composition, n is became viscous. When preparing mixtures with this instability during storage some songs were more difficult to make a viscous, in order to achieve an acceptable viscosity, especially when using relatively low levels of surface-active substances.

Extensive research and chemical analysis showed that there was an interaction of the products of hydrolysis sulfosuccinate surfactant to amphoteric surface-active substance which was responsible for anomalous salustiana during storage. In addition, it was found advantageous to include a limited number of alkylalkoxysilane with the length of the alkyl chain, equal to or greater than 16 carbon atoms, in order to improve the stability of the foam and especially the structure of the product. However, the inclusion of too many long alkylalkoxysilane had a dramatic adverse effect on the storage stability, especially when stored in a high temperature environment. These discoveries provided the basis for the creation of practical compositions shampoos and compositions for washing the skin, in which are used sulfosuccinate surfactant in combination with an amphoteric surface-active substance. These combinations have the advantage that they provide a very soft song, that do not make p the d threat foam, efficient and economical and well compatible with the conditioning means for hair and skin.

These and other advantages of the compositions disclosed herein will become apparent from the description.

Considering the invention relates to compositions for soft hair and skin, which gives a great lather and is very effective from the point of view of the relatively low total content of surfactants, which is required.

More specifically soft water composition contains:

DETAILED description of the INVENTION

In this document % or wt.% refers to the percentage by weight of ingredient compared to the total weight of the composition or component discussed.

Except operative and comparative examples, or where explicitly indicated another, all numbers in this description indicating the amount of material or conditions of reaction, physical properties of substances and/or use, should be understood as adjusted by the word "about". All quantities are given by weight of the final composition, unless otherwise indicated.

It should be noted that if you specify any range of concentration of any particular higher concentration may be associated with any particular lower concentration.

To avoid doubt, it is understood that the word "comprising" means "including," but not necessarily "consisting of", and "composed of". In other words, each of these stages or items of choice should not be exhaustive.

The present invention relates to soft compositions suitable for washing hair and human skin. The composition contains a system of surface-active substances and various optional additives and additives for hair care and/or skin. These components are described in detail below.

The SYSTEM of SURFACE-ACTIVE SUBSTANCES

The system of surface-active substances consists of a combination of two main classes of surfactants: one class includes alkylalkoxysilane anionic surfactants, and the other class includes amphoteric surfactants.

Alkylalkoxysilane anionic surfactant preferably is poluation having the General formula:

where R is an alkyl group with unbranched or branched chain, X is a number that indicates the average degree of ethoxyline and ranges from about 1 to about 5, and M and M' are monovalent cations, which may be the same or different from each other. Preferred cations are alkali metal ions, for example sodium or potassium, ammonium ions Il the ions alkanolamine, for example ions of monoethanolamine or triethanolamine.

It has been unexpectedly discovered that it is advantageous to use a mixture of alkylalkoxysilane, consisting of a larger number of medium chain alkylalkoxysilane and fewer long alkylalkoxysilane.

Medium chain alkylalkoxysilane in the present description are defined as sulfosuccinate, in which the average length of unbranched or branched alkyl chain, denoted as RMCis from about 10 to about 14 carbon atoms.

Long-chain alkylalkoxysilane in the present description are defined as sulfosuccinate, in which the average length of unbranched or branched alkyl chain, denoted as RLCis from about 16 to about 18 carbon atoms.

The level of long-chain alkylethoxysulfates component present in the composition should be at a level from about 0.1% to about 6% of the total weight of medium chain alkylalkoxysilane, preferably at a level from about 0.2% to 5% and most preferably from about 0.3% to about 5%. Found that the levels of long chain sulfosuccinate that are below nignog the limit, approximately 0.1% of medium chain of sulfosuccinate, cannot effectively provide increased initial viscosity and improved stability of the foam. In contrast, the levels of long chain sulfosuccinate that exceed approximately 5% of medium chain sulfosuccinate, lead to unacceptable increase in viscosity during long-term storage, especially storage at elevated temperatures, and make it impossible to save the viscosity after storage initial viscosity.

The term "initial viscosity" refers to the viscosity of the composition after preparation and storage at room temperature (approximately 25-27°C) for sufficient time to allow to come into equilibrium. As a rule, before registering the initial viscosity of the sample is allowed to come into equilibrium during the night (15-24 hours).

The term "maintaining the viscosity after storage initial viscosity" means the viscosity of the composition after storage has no obvious differences for the unprepared observer in the ordinary course of application of the composition. To achieve this level of "saving" viscosity, as a rule, it is required that the viscosity after storage has not changed (i.e. increased) by more than approximately 75% of the initial value and preferably remain within approximately the additional 65% of the initial value. Thus, the level of long chain sulfosuccinate selected in order to achieve the desired initial viscosity not exceeding the upper threshold of instability during storage. The exact level, however, depends on the specific composition. For example, if the total amount present of medium chain sulfosuccinate relatively low (for example, 2-3% by weight of the composition)can be used higher levels of long chain sulfosuccinate.

As you know, as a single indicator of stability during prolonged storage is convenient to use accelerated testing of storage, wherein the test composition is exposed to elevated temperature. In this context, it is preferable that the composition retains its viscosity after storage at 49°C for at least about 4 weeks of storage, and most preferably at least about 11 weeks of storage.

Especially preferred medium chain alkylalkoxysilane is lauroylsarcosinate, also known as laurilsulfosuktinat, and especially preferred long-chain sulfosuccinate is palmitoylethanolamide.

The level of medium chain alkylsulfonates surfactants, p is outstayed in the composition, may be in the range of from about 1% to about 20% by weight of the composition, preferably from about 1% to about 10% and most preferably from about 1.5% to about 7% of the composition.

Sometimes it is convenient to prepare the desired mixture of medium chain and long chain sulfosuccinate by synthesizing alkylalkoxysilane from a combination of ethoxylates of alcohols suitable length. In this case, the resulting mixture alkylalkoxysilane can be analyzed to confirm that the desired ratio of medium chain and long-chain varieties. For this analysis, the inventors used a standard liquid chromatography with mass spectrometric detector. Specifically, it was found that works well for standard HPLC with reversed phase, which uses octadecylsilane column with gradient elution of water-methanol, and the spectrometer ion trap Finnigan LCQ (electrospray ionization).

The second essential component of the surfactant is an amphoteric surfactant.

Particularly preferred amphoteric surface-active substance is betainovuyu surfactant having the following General is Y. the chemical formula:

Particularly preferred betaines are laurylether or betaine fatty acids of coconut oil and laurylether or aminopropylation fatty acids of coconut oil. The term "lauryl" refers mainly to fatty acid chain length C12, while the fatty acids of coconut oil are related to the mixture of fatty acids with a chain length of C12and C14.

The second type of suitable amphoteric surfactant is hydroxysultaine (CTFA name for sulfobetaine with the presence hydroxypropanesulfonic group), which usually is formed by the reaction of tertiary amine with epichlorohydrin and bisulfite. Their General formula is:

where R1 is alkyl or, or acylaminoalkyl group. In any case, the alkyl group can in order to be alkyl group, branched or unbranched chain, having 8-18 carbon atoms, preferably 10 to 16 carbon atoms and most preferably 10-14 carbon atoms.

Preferred hydroxysultaine are sultain fatty acids of coconut oil and lauramidopropyl, and aminopropyltriethoxysilane fatty acids of coconut oil.

Another class of amphoteric surfactants is formed by the reaction of imidazoline with Chloroacetic acid. This class includes fatty atacamite and fatty apodicticity having the General formula shown below. These substances were officially known as impulsitivity and amlodipine, respectively.

where R is an alkyl chain with an unbranched or branched chain, having 10-16 carbon atoms, and R2is either H or-CH2-COOH.

The preferred ampharetidae are ampharetid fatty acids of coconut oil, lauroamphoacetate, and preferred apodictically are lauroamphodiacetate and amfiteatar fatty acids of coconut oil.

Other less preferred amphoteric surfactants include 10-C16fatty impecablemente and C10-C16fatty amfepramone.

Another class of amphoteric surfactants is aminoxide fatty series, such as lauryldimethylamine. These surfactants were classified by various workers as "nonionic" surfactants, "cationic" surfactants and amphoteric" surfactants. N-oxide group is a weak base with a pH of approximately 9. Thus, at pH 5 to approximately 50% of the molecules exist in the form of a positive N+HE types, while at a pH of 6.5 only about 3% are in the form of positively charged species. For the purposes of the present invention aminoxide fatty series classified as amphoteric surface-active substances.

Level amphoteric surfactant present in the composition may range from about 1% to about 20% by weight of the composition, preferably from about 1% to about 10%, and most preferably from about 1.5% to about 5.5% of the composition.

Alkylalkoxysilane may be present in the composition in an amount of from about 1% to about 25%, preferably from about 4% to about 12%, and most preferably from about 4% to about 8% by weight of the total composition.

The total content of surfactants in the compositions of the invention under examination can range from approximately 1 to approximately 30% by weight. However, since the compositions are intended for final destination - wash hair and skin consumers, and not as concentrates, the content of the surfactant is preferably from about 3% to about 25% and most preferably from about 4% to about 15%.

OPTIONAL INGREDIENTS

Buffer means

the pH of the composition in accordance with the desire ranges from about 5 to about 7, preferably from about 6 to about 6.5, and most preferably from about 6.1 to about 6,4.

T is the train preferable to achieve adequate acid buffering, to counteract changes in pH, because it was found that this improves the physical stability of the composition during storage.

Acid buffering capacity is defined as the number of moles of acid (for example, hydrated protons or hydrogen ions)that you want to add to one liter of the composition, to cause a decrease in pH by 1 pH unit. Acid buffering capacity can be measured by titration of the investigated compositions (typically 10-fold dilution) standard solution of a strong acid, such as HCl, using the electrode for measuring pH. In practice it was found that the acid buffering capacity of the composition should be at least about 0.01 mol of hydrated hydrogen ions, preferably at least about 0.02 mol, and most preferably at least about 0.03 mol per liter of the composition.

As the buffer system can be used in a variety of couples acid/base, which is well known from the prior art. Particularly suitable buffers are citric acid, neutralized with sodium hydroxide or ammonium, and polyacrylic acid, neutralized with sodium hydroxide or ammonium.

The stabilizer during storage

In addition sulfonterol acid was found that the electrolytes that provide defined the soluble cations, also can improve the stability of mixtures sulfosuccinate surfactant/amphoteric surfactant during storage at high temperature. Adding these electrolytes also helps to prevent an unacceptable increase in viscosity of the compositions during storage, which apparently is unusual property of mixtures sulfosuccinate and amphoteric surfactants. In the present invention such electrolytes are useful optional ingredients.

Preferred electrolytes used in the present invention are those that completely dissociate in liquid and composite ions which are completely dissolved. Thus, the preferred electrolytes are not deposited in the form of various types with other components of the composition.

The preferred electrolytes are those which vysokochastotnymi in the compositions according to the invention and most effectively deliver the desired cations, in and of themselves do not render harmful influence on the softness, the pH or the solubility of other ingredients of the composition.

Especially preferred water-soluble salts of monovalent inorganic ions, especially ammonium salts, sodium and less potassium. They include chlorides, sulfates, carbonates, and various salts of weak the x organic acids, such as citrates, glycolate, succinate and salts of acrylic/poly (acrylic acid), and mixtures thereof.

Preferably the anion of the electrolyte should not be a molecule surfactants, are able to form micelles in water levels used in the song, because it greatly reduces their availability in solution. Thus, if the anion is an organic molecule, it preferably should not be unsubstituted hydrocarbon chain is longer than about 5 carbon atoms.

The preferred ammonium chloride and sodium citrate and polyacrylate, and mixtures thereof.

The exact level of electrolyte required to maintain the viscosity of the composition near its initial value (in the sense discussed above), depends on composite parts and their levels. In particular, the level of cation depends on the total percentage by weight sulfosuccinate surfactants used in the composition. The electrolyte level must be greater than or equal to about 1% by weight of the composition, preferably at least about 1.5% and most preferably at least about 2%.

Analysis of the solubility of Zein in vitro

The solubility of Zein is a simple directional indicator softness and widely used technique to test the softness as raw surfactants, and shampoos, and compositions for washing the skin. Zein is a protein (a mixture of amino acids derived from corn), which swells and is subjected to denaturation under the action of surface-active substances like proteins of the keratin of the skin. This procedure was developed on the basis that the more Zein is soluble under the action of a given composition at standard test conditions, the stronger rasaraj the abuser action of the composition. The solubility of Zein is not intended to replace clinical studies or more biologically based analysis of the leakage of fluorescein in vitro, even if demonstrated acceptable correlation. Thus, the main use for the solubility of Zein - preselection, where it serves as a good prognostic sign of possible annoying abilities. When used, the test conditions described below, the solubility of Zein less than 1% is a good sign of a potentially soft songs, while the solubility of Zein more than 1% is a good indication that the composition will irritate eyes.

EXAMPLES

The following examples are given as illustrations of the invention, and it is not expected that they will in any way limit its scope.

EXAMPLE 1. This example illustrates the criticality of the ratio of medium chain and long-chain alkylalkoxysilane surface-active substances.

Examples 1A through 1E, whose composition is shown in table 1, were prepared as follows by combining the premix described below:

Preparation of premix:

Premix Carbomer 980 in accordance with instructions: this premix was obtained by dissolving Carbomer 980 in water at room temperature, and stirring until complete hydration and dissolution (no lumps or "fish eyes").

Premix Jaguar C13S (B) (or other cationic polymer) was obtained, re eseva Jaguar C13S in propylene glycol for 10 minutes or until dissolved and smooth.

Premix ammonium chloride or NaCl/sodium citrate 25 wt.% (C) was obtained by adding ammonium chloride (or sodium chloride) and the dihydrate of sodium citrate in water and stirring until complete dissolution.

Premix distearate PEG-150 (5 wt.%) (D) was obtained by adding a portion of amphoteric surfactants to aqueous solution, heated to 65°C. the Mixture was cooled to room temperature and was added an additional amount of water in accordance with the instructions.

B. principal party:

To the mixer was added water, and then added to the premix Carbomer (A). Optional surfactant, such as sodium Laureth sulphate, was added with stirring in accordance with the instructions (for example, SLES-1, 70%) and stirred to disperse. Then add the premix Jaguar C13s (B) and the batch was stirred at 100 rpm./minutes to 30 minutes. Then added and dispersively disodium laurilsulfosuktinat and disodium palmitoylethanolamide, then added the remainder of amphoteric surfactants. Then added and dispersively the substance giving a pearly luster, preservatives and sodium hydroxide. Followed premix ammonium chloride or NaCl/sodium citrate 25 wt.% (C). Then measured the viscosity and pH and regulate their additional amount of salt, ppg-9, or premix PEG-150DS D) and NaOH or citric acid, respectively.

The initial viscosity of the compositions of the examples and the viscosity after storage recorded at the bottom of table 1.

Example 1A shows that when the level of long chain alkylalkoxysilane below 0.1% (0,04% palmitoylethanolamide in this case), the initial viscosity decreases by about 30% from the value of the plateau of approximately 550 SP. On the contrary, in this example, when the concentration of long chain sulfosuccinate exceeded 5% in relation to the medium chain sulfosuccinate, the viscosity of the composition after storage was increased by more than 75%. This can be seen by comparing the composition of Example 1E with the comparative examples 1A and 1B, where the increase of viscosity was calculated by extrapolating the experimental results of examples 1 through 1E, using the method of least squares.

The increase in viscosity after 11 weeks of storage at s460027001488a704a-406a

a) Extrapolated values based on data storage for 4 weeks at 49°C

The viscosity changes after accelerated storage (11 weeks at 49°C) recorded at the bottom of table 2. Several points deserve attention.

The greatest increase in viscosity after accelerated storage was observed in compositions that contain as sulfosuccinate surfactant, and amphoteric surface-active substance - in this case, betaine (compare Example 2A and Example 2B with Comparative examples 2A-2C). In addition, not only in these combinations the upper level of long chain alkylalkoxysilane critical for stability during storage (compare the viscosity after storage in Example 2A Example 2B).

In contrast, compositions that do not contain amphoteric and alkylalkoxysilane surface-active substance, do not show such a strong increase in viscosity after storage, and their viscosity does not respond to such a level of long chain alkylalkoxysilane.

EXAMPLE 3. This example illustrates in Janie softness and foam Association sulfosuccinate surfactant to amphoteric surface-active substance.

The average score of the foam (which was measured by the group's subjective evaluation of the foam described above in the section on methodology) and softness in vitro (which was measured test the solubility of Zein as described above in the section on methodology) recorded at the bottom of table 3.

According to the results it is clear that all investigated combinations of surface-active substances, the combination alkylalkoxysilane, alkylalkoxysilane surfactants and amphoteric surfactants (Example 3) had the lowest solubility of Zein and, therefore, it is expected that they will be the most soft compositions for skin and hair. In addition, this combination had a great foam and, therefore, did not sacrifice performance and efficiency for softness (compare Example 3 With anicely example 3B).

Therefore, this example demonstrates the desirability of combinations sulfosuccinate surfactants and amphoteric surfactants for washing the hair and skin of humans and the importance of resolving the problem of stability during storage associated with such combinations.

Soft (solubility of Zein) and the formation of foam is particularly preferred embodiment of the invention is a composition consisting essentially of:

Disodium of laurilsulfate2-6%
Disodium of palmitoleate relatively
disodium of laurilsulfate

Laurilethersulfate (1-3 EO)5-9%

which provides solubility of Zein, less than or equal to 2, measured in the test solubility of Zein, and the average score of the foam at least 3 measured by the group's subjective evaluation of foam.

The term "consisting essentially of"as used in this context, means that the various optional ingredients may be included, provided that they do not pose a threat the RAM (i.e. reduce) the mildness and foaming of the composition below the threshold values, as defined earlier.
