Description

  The present invention relates to a concentrated liquid hair cleanser composition, and more particularly to a concentrated liquid hair cleanser composition that does not cause precipitation due to a cationic polymer and a method for producing the same.

  Hair cleansing compositions that use ionic surfactants include, in addition to liquids, solid compositions such as solid soaps and cinderette bars, or cream-like compositions such as facial cleansing foams. The solid or creamy hair cleansing composition is mainly composed of an anionic surfactant having a hydrophilic group moiety as a carboxylic acid. However, it has a feeling of use when applied to hair or skin, or in hard water. Foaming and detergency were not good. In addition, a solid or cream hair cleansing composition mainly composed of an anionic surfactant whose hydrophilic group portion is not a carboxylic acid has been known, but the usability and ease of use are not good. Therefore, from the viewpoint of ease of use, the hair cleaner composition is often in a liquid form. And such a liquid hair cleaning composition was a composition containing 60-80% of water, generally mix | blending 10-20% of ionic surfactant.

On the other hand, in recent years, the production and flow rate of hair cleaning compositions have occupied an overwhelming proportion in the cosmetics field, and the energy required for physical distribution due to the weight and bulkiness of a large amount (60 to 80%) of water content. Is too high. Examples of initiatives to address these issues include improvements in transportation technology and means (logistic efficiency, modal shift, improved product packaging technology, etc.), weight reduction of containers (reduction of container weight, sales of refill products) Etc.) has already been made.
As another means for reducing such energy, it is conceivable to reduce the moisture contained in the liquid hair cleanser composition to be a concentrated type. However, when a conventional liquid hair cleaning composition is simply concentrated, there is a problem that a cationic polymer, which is one of the components widely used in the cleaning composition, is deposited.

  Cationic polymers are blended in many hair care products including hair cleansing compositions such as shampoos for the purpose of imparting conditioning effects in addition to thickening and stability. In the case of a detergent composition mainly composed of an anionic surfactant such as shampoo, the cationic polymer forms a complex with the anionic surfactant when the detergent composition is applied to the hair and washed away. A thin film is deposited on the hair surface. It is known that this film is usually retained on the hair in a cured state even after the cleaning composition is washed away and dried, and provides a conditioning effect such as suppleness and smoothness.

  The solubility of such a cationic polymer decreases in regions where the concentration of anionic surfactant is low and in regions where the concentration of anionic surfactant is low, and in these regions, the complex of cationic polymer and anionic surfactant precipitates as described above. I know you will. On the other hand, when the anionic surfactant concentration is in the middle of the two regions, the cationic polymer maintains high solubility and no precipitation of the complex is observed. Therefore, in the liquid hair cleansing composition, the anionic surfactant is usually in the intermediate concentration range so that the complex does not precipitate, and this is shifted to the low concentration range by rinsing and the complex. Is adjusted to precipitate.

Here, when the normal liquid hair cleansing composition containing the general cationic polymer as described above is concentrated, as a matter of course, the concentration of the anionic surfactant is remarkably increased. That is, the anionic surfactant enters the above-described high concentration region by concentration, and in the product state, a complex with the cationic polymer is precipitated and a precipitate is generated.

In this case, when the blending amount of the component (B) is less than 20% by mass or exceeds 40% by mass with respect to the composition, the viscosity of the composition before dilution becomes high and preparation becomes difficult. The viscosity of the composition increases significantly during dilution, making it difficult to dilute, or the viscosity of the composition after dilution may be extremely low and difficult to handle.

  In addition, the commercially available anionic surfactant raw material as described above is marketed as a liquid solution having a fluidity of 25 to 40% or 65 to 75%, or a solid state containing 85 to 100% without water. In the production of a liquid detergent composition that is supplied and not concentrated, a raw material that is an aqueous solution having a concentration of 25 to 40% is used. In the present invention, from the viewpoint of obtaining a concentrated composition, it is preferable to use a raw material having a higher concentration of anionic surfactant, preferably 50% or more. In addition, a raw material dissolved in a liquid form is preferable from the viewpoint of ease of production, rather than a dried and powdered raw material as an anionic surfactant. The higher the concentration of the active agent in the raw material is, the more efficiently the concentrated detergent composition containing the anionic surfactant more densely.

(C) Amphoteric surfactant With respect to the amphoteric surfactant to be blended in the present invention, those which are usually used in cosmetics, pharmaceuticals and the like can be used. Examples of amphoteric surfactants suitable for the present invention include betaine acetate type amphoteric surfactants represented by the following general formulas (IX) and (X).

Examples of the substance include Anon BL-SF (manufactured by NOF Corporation), Levon 2000-SF (manufactured by Sanyo Chemical Co., Ltd.), Genegen Cab 818J (manufactured by Clariant Japan), TEGO Betain C60 (manufactured by Degussa), and Dehyton PK45 ( Commercial products such as Cognis Co., Ltd.), Nissan Anon BDC-SF (manufactured by Nippon Oil & Fats), and ovazoline 662N (manufactured by Toho Chemical Co., Ltd.) can be used.

In the present invention, the blending amount of the (C) amphoteric surfactant is 0% by mass when the (B) anionic surfactant is used alone as a cleaning agent, and the (B) and (C) components are used in combination. Is 10 to 40% by mass, preferably 10 to 25% by mass, and more preferably 15 to 22% by mass with respect to the composition. In this case, if the blending amount of the component (C) is less than 10% by mass with respect to the composition, the viscosity of the diluted solution may be remarkably lowered. On the other hand, when it exceeds 40% by mass, the viscosity of the composition before dilution becomes high and preparation becomes difficult, or the viscosity of the composition significantly increases during dilution, which may make dilution difficult.
In addition, the above-mentioned commercially available amphoteric surfactant raw material is normally supplied to the market as a 25-40% aqueous solution. In the present invention, from the viewpoint of obtaining a concentrated composition, it is preferable to use a raw material having a higher concentration of the amphoteric surfactant, preferably 35% or more. The higher the concentration of the active agent in the raw material is, the more efficiently the concentrated detergent composition containing the amphoteric surfactant can be obtained more efficiently.

  Moreover, in this invention, the total compounding quantity of the said (B) component which is a washing | cleaning component, and (C) component is 40-60 mass% in a pure part with respect to a composition. If the total blending amount of these surfactants is less than 40% by mass, the merit as a concentrated composition is diluted and unattractive. On the other hand, if it exceeds 60% by mass, a composition that is easily diluted with water cannot be obtained.

(D) concentrated detergent composition according to the water present invention, containing 45 wt% water. In the present invention, water can be appropriately added as a single component, but it is usually sufficient to add water as a solvent for the surfactant raw material. In general, anionic surfactants, amphoteric surfactants and the like are commercially available as high-concentration aqueous solutions of about 25 to 40%. Therefore, the use of these surfactants in the state of the aqueous solution can also serve as a blend of water in the present invention.
The presence of water exceeding 45% by mass is not preferable from the viewpoint of reducing energy required for production and transportation of products. In particular, the water content in the present invention is preferably 10 to 30% by mass, more preferably 20 to 30% by mass, based on the composition.

In the concentrated cleaning composition as in the present invention, the surfactant component (cleaning agent) concentrated in the production process may gel, and mixing of the components may be difficult. Therefore, in general, a gelation inhibitor such as a salt is used as an additive, and the concentrate is adjusted so as to have a viscosity that is as easy to handle as a normal liquid hair cleaning composition. However, the concentrated composition obtained in this way often has problems such as dripping during use because the viscosity further decreases with dilution with water.
Of course, it is not impossible to obtain a concentrate by a method such as simply adding a large amount of each of anionic and amphoteric surfactants that are detergents or reducing the water content of the detergent by drying. However, when the composition thus obtained is diluted with water, a region in which the viscosity increases remarkably may appear in the dilution process. For example, in Test Example 1 of FIG. 1, a composition obtained by diluting a 70% aqueous solution (Texapon N70, manufactured by Cognis) of a common sodium POE lauryl ether sulfonate (LES) as a cleaning component at various magnifications. The change in viscosity (30 ° C.) is shown.

According to FIG. 1, the viscosity of the LES 70% aqueous solution increases rapidly from the start of dilution, and reaches a peak (about 1 million mPa · s) when the dilution factor is 1.5 times. Furthermore, when the dilution rate exceeds 2 times, the viscosity rapidly decreases, and when the dilution rate is 2.5 times, the viscosity drops to about 100 mPa · s. In other words, a concentrated liquid detergent containing an anionic surfactant at a concentration three times the normal concentration as a cleaning component is unstable when first trying to dilute, becoming harder to mix and then suddenly loosening. Shows behavior.
Moreover, Test Example 2 in FIG. 1 includes POE sodium lauryl ether sulfate, coconut oil fatty acid amidopropyl betaine solution, and alkyl (8-16) glucoside, and the concentration of the anionic surfactant is about 45% by mass. This shows the viscosity change due to dilution of a detergent mixture base (Plantapon 611C, manufactured by Cognis) in which the total amount of the surfactant is about 64% by mass. Similarly to Test Example 1, the composition of Test Example 2 has a viscosity that rapidly increases and decreases with the dilution factor, and is very difficult to handle as a concentrate to be used after dilution.

Such a viscosity change due to dilution of the cleaning component is considered to be due to a change in the association structure of the active agent.
In general, when the surfactant exceeds a critical micelle concentration (hereinafter referred to as cmc) in a solvent (water), a string-like micelle is formed, and when the concentration is further increased, an aggregate structure is formed into a lamellar liquid crystal through a hexagonal liquid crystal. It is known to change. Therefore, when a high-concentration surfactant is simply diluted with water, the aggregate structure changes from lamellar liquid crystal → hexagonal liquid crystal → string-like micelle. Among them, lamellar liquid crystal and hexagonal liquid crystal are gel-like structures having high viscosity, and particularly hexagonal liquid crystal is a very hard gel. That is, the high-viscosity region shown by Test Examples 1 and 2 in FIG. 1 is considered to be a region where the aggregate structure of the surfactant is a lamellar liquid crystal or hexagonal liquid crystal.

  On the other hand, when highly soluble alcohol is added as a solvent for the cleaning component, the cmc increases, and the surfactant maintains the structure of the string-like micelle even in a high concentration state. In Test Example 3 of FIG. 1, 8% by mass of dipropylene glycol was added to a mixed base of a detergent containing 32% by mass of POE sodium lauryl ether sulfate and 8% by mass of amphoteric surfactant. It is the viscosity change in the system. As Test Example 3 shows, since the surfactant maintains string micelles, no increase in viscosity due to changes to lamellar liquid crystals and hexagonal liquid crystals is observed. However, as the dilution factor increases, the viscosity decreases immediately, and a viscosity suitable for cleaning (about 300 mPa · s) cannot be maintained. For this reason, it is difficult to use as a cleaning composition. Such thinning is considered to occur because alcohol weakens the packing state of the hydrophilic group in the micelle and increases the fluidity.

Therefore, in the present invention, it is preferable to add a nonionic surfactant as a cosurfactant. Cosurfactants exert an effect of strengthening hydrophobic interaction while alcohol gradually weakens the packing of hydrophilic groups, while gradually entering into the aggregate. Therefore, as shown in Test Example 4 in which the nonionic surfactant coconut oil fatty acid N-methylethanolamide (Aminone C-11S, manufactured by Kao Corporation) is added to Test Example 3 in FIG. The fluidity does not increase even by dilution with, and the moderate viscosity is maintained.
Therefore, from the viewpoint of maintaining a viscosity that is easy to handle before and after dilution, the concentrated liquid hair cleaning composition according to the present invention includes (E) a monovalent or divalent alcohol, and (F) IOB 0.8 to 1.1. It is preferable to blend a nonionic surfactant having a molecular weight of 500 or less.
Hereinafter, each component will be described.

(E) Monovalent or Divalent Alcohol The monovalent or divalent alcohol used in the present invention is not particularly limited, but considering the storage stability as a concentrated detergent composition and the ease of handling during dilution. In addition, those exhibiting a liquid state at less than 50 ° C. where the composition is expected to be stored and used are preferable.
Such as, for example, ethanol, isostearyl alcohol, jojoba alcohol as monohydric alcohol, dipropylene glycol, 1,3-butylene glycol, propylene glycol, 1,2-pentanediol, isoprene glycol as dihydric alcohol Hexylene glycol, 1,2-octanediol and the like. Of these, ethanol, dipropylene glycol, butylene glycol, propylene glycol, and isoprene glycol are particularly preferable.
The compounding quantity of (E) monovalent or divalent alcohol in this invention is 5-25 mass% with respect to a composition, More preferably, it is 10-20 mass%. If the blending amount of component (E) is less than 5% by mass with respect to the composition, the viscosity of the composition before dilution becomes high and preparation becomes difficult, or the viscosity of the composition significantly increases during dilution. Dilution may be difficult. Moreover, when a compounding quantity exceeds 25 mass%, the viscosity of the solution after dilution may become remarkably low and it may become difficult to handle.

(F) Nonionic surfactant having an IOB of 0.8 to 1.1 and a molecular weight of 500 or less The nonionic surfactant used in the concentrated detergent composition according to the present invention has an IOB of 0.8 in the organic conceptual diagram. It is a compound having a molecular weight of 500 or less at -1.1.
Examples of such nonionic surfactants include long-chain fatty acid diethylene glycol, long-chain fatty acid propylene glycol, long-chain fatty acid diethanolamide, long-chain fatty acid fatty acid N-methylethanolamide, long-chain fatty acid (POE) 2 monoethanolamide. Etc. that satisfy the IOB range and the molecular weight range. If the IOB is less than 0.8, or if the IOB is greater than 1.1, a significant viscosity increase occurs during dilution, the viscosity after dilution is significantly reduced, or the solution composition after dilution is not one phase. On the other hand, if the molecular weight exceeds 500, the viscosity of the diluted composition becomes extremely low. In the present invention, fatty acid diethylene glycol having an average carbon number of 10 to 14 and fatty acid N-methylethanolamide having an average carbon number of 10 to 14 are particularly preferable.

Moreover, as a commercially available nonionic surfactant, for example, Genapol DEL (manufactured by Clariant Japan) is used as diethylene glycol laurate, and Aminone C-11S (manufactured by Kao) is used as palm oil fatty acid N-methylethanolamide. Can be used for
The compounding quantity of (F) nonionic surfactant in this invention is 5-20 mass% with respect to a composition, More preferably, it is 10-15 mass%. When the blending amount of the component (F) is less than 5% by mass with respect to the composition, the viscosity of the diluted solution may be remarkably lowered. Further, if the blending amount exceeds 20% by mass, the viscosity of the composition before dilution becomes high and preparation becomes difficult, or the viscosity of the composition increases significantly during dilution, which may make dilution difficult. .

  Moreover, in this invention, Preferably the total compounding quantity of the said (E) component and (F) component is 20-30 with respect to the composition which contains 40 mass% or more of (B) component and (C) component in a pure part. % By weight, more preferably 22-24% by weight, and in particular, the blending ratio of (E) and (F) is (E) :( F) = 3.5: 1 to 1: 2.5, Preferably it is 2: 1 to 1: 1.5. When the total blending amount is less than 20% by mass, that is, when the ratio of the component (B) and the component (C) is too large, the concentrated detergent composition may not be easily diluted with water. Further, when the total blending amount exceeds 30% by mass, that is, when the ratio of the component (B) and the component (C) is too small, the diluted detergent composition is easily diluted in water, but the solution after dilution May become too low in viscosity.

The concentrated detergent composition according to the present invention can be produced by a known method. For example, after adding (A) a cationic polymer to an aqueous solution of (B) an anionic surfactant and mixing, if necessary ( C) It is obtained by adding and mixing an aqueous solution of an amphoteric surfactant.
Moreover, when mix | blending (E) and (F) component as a solvent and a cosurfactant, (E) monovalent | monohydric is added to the aqueous solution of (B) anionic surfactant, and the liquid mixture of (A) cationic polymer, for example. Or after adding and mixing a dihydric alcohol and (F) nonionic surfactant, water was reduced from the composition by adding and mixing the aqueous solution of (C) amphoteric surfactant as needed. The concentrated detergent composition can be easily produced without facing the high viscosity region that occurs in the process.
In addition, in the said manufacturing method, (E) and (F) component may be added and mixed to the aqueous solution of (B) component, and (A) component may be added and mixed.

Specifically, for example, after mixing an aqueous solution of (B) an anionic surfactant and (A) an aqueous solution of a cationic polymer at room temperature, (E) a monovalent or divalent alcohol and (F) as necessary. Add an aqueous solution of nonionic surfactant and mix until uniform. At this time, if the viscosity increases and bubbles are likely to be entrained by mixing, heating may be performed. Then, the composition of this invention can be obtained by adding and stirring the aqueous solution of (C) amphoteric surfactant.
When producing a conventional liquid hair cleansing composition having a high water content, the order of mixing the constituents does not greatly affect the production of the composition. However, in the production of the concentrated liquid hair cleansing composition containing the components (A) to (F), if the order of addition is different from the above, the viscosity is remarkably increased and the production of the composition may be difficult.

  The concentrated liquid hair cleansing composition of the present invention composed of such components and production method becomes a normal liquid hair cleansing composition by mixing with water. Therefore, the present invention can be used as a hair shampoo precursor composition that can be used in the same manner as conventional hair shampoos, for example, by mixing and diluting an appropriate amount with water or the like at the time of use. The specific dilution ratio of the present invention can be appropriately adjusted according to the blending amount of the essential components and the blending ratio thereof, but the total concentration of the component (B) and the component (C) is usually pure. By diluting to 15% by mass, a cleaning effect comparable to that of a conventional liquid hair shampoo can be obtained. Therefore, for example, when the blending amount of (B) + (C) is 40% by mass with respect to the composition, an appropriate dilution ratio is about 2.6.

In the present application, the range of viscosity change of the composition during dilution with water until the total concentration of the component (B) and the component (C) is 15% by mass, and the composition after the dilution. The viscosity was evaluated using only 15% by mass as a standard dilution rate, but does not limit the dilution rate of the concentrated detergent composition of the present invention.
Moreover, although the dilution speed | rate will increase, so that the temperature of the water to dilute becomes high, even room temperature (20-30 degreeC) water can fully dilute. Further, the hardness of the water to be diluted has little influence on the dilution rate, and depending on the dilution method, it can be sufficiently diluted even if the hardness is high.
In addition, the concentrated liquid hair cleanser composition according to the present invention can be used by diluting it in a container of an appropriate size before use, even if the necessary amount is diluted on the palm every time it is used. Also good.

Moreover, when (E) and (F) component are mix | blended, in the concentrated liquid hair cleaning composition of this invention, since the high-viscosity area | region depending on water content does not exist, before dilution-during dilution-after dilution The viscosity is easy to handle.
In general, a liquid composition can be easily mixed when the viscosity measured by a B-type viscometer at 30 ° C. is 20000 mPa · s or less, and when it exceeds 50000 mPa · s, mixing is considered to be difficult. Therefore, while the liquid viscosity of the composition (stock solution) of the present invention described above and the composition is diluted with water until the total concentration of the component (B) and the component (C) is 15% by mass in a pure content. The liquid viscosity is 50000 mPa · s or less, preferably 20000 mPa · s or less at 30 ° C. and normal pressure.

Furthermore, the liquid viscosity after dilution of the concentrated liquid hair cleaning composition of the present invention is set to 300 mPa · s or more at 30 ° C. and normal pressure. If the viscosity of the composition at the time of dilution, that is, when used is less than 300 mPa · s, the viscosity is too low to be handled, and it is difficult to apply the composition to the entire hair. In particular, the liquid viscosity after dilution is preferably adjusted to be 300 to 20000 mPa · s (30 ° C.) in consideration of ease of handling during use as a cleaning agent. When the viscosity at the time of use exceeds 20000 mPa · s, the viscosity is too high, and it becomes difficult to apply to the object to be cleaned and put it in and out of the container.
That is, in the present application, the composition “easy to handle before and after dilution” means that the viscosity increase (viscosity change) during the dilution due to the influence of the aggregate structure of the surfactant is 50000 mPa · s, preferably 20000 mPa · s. The viscosity after dilution (during use) is 300 mPa · s or more, preferably 300 to 20000 mPa · s.
Further, the phase state of the composition of the present invention and the diluted product thereof is preferably one phase. It is not preferable that the composition is separated into two phases in terms of stability as well as ease of handling of the composition.

Furthermore, in the concentrated liquid hair cleanser composition according to the present invention, an organic or inorganic salt may be blended in order to reduce the viscosity of the composition in the high viscosity region and make it easier to dilute into water. Is preferred.
Examples of the salt include organic acid salts, amino acid salts, and inorganic salts.
