Description

  The present invention relates to a liquid body cleaning composition that is excellent in foam creamy immediately after preparation and after storage, and that suppresses precipitation and is excellent in storage stability even when kept at a low temperature after storage over time.

  Conventionally, liquid body cleansing compositions mainly composed of fatty acid salts are superior in foam creaminess compared to other anionic and amphoteric active agents, so solid soaps, body soaps, hand soaps, etc. Is widely used. However, in liquid preparations based on fatty acid salts, precipitation of fatty acids at low temperatures has been a problem.

  Techniques using condensed ricinoleic acid polyglycerin esters (see Patent Document 1: 2002-068961), alkyl sulfates and alkyl amides as a method for improving the low-temperature stability of a liquid body cleaning composition mainly composed of fatty acid salts Technology that uses an anionic activator having a sulfate group such as sulfate, amphoteric polymer, and cationic polymer (Patent Document 2: 2003-073257), composition ratio of fatty acid, and ratio of fatty acid / fatty acid potassium salt Technology (Patent Literature 3: 2003-160470), a technology for specifying the composition ratio of fatty acids (Patent Literature 4: 2005-154651), fatty acids having a specific composition, amphoteric surfactants, and polyols Technology (Patent Document 5: 2005-206812), alkylene oxide derivative, and specific ratio of fat Technology using acid (Patent Document 6: 2005-281641), Technology using N-acyl aspartate (Patent Document 7: 2005-350645), Technology using glycerol derivative added with alkylene oxide (Patent) Document 8: 2006-241212), a technique using sodium alginate or pectin and a polyhydric alcohol (Patent Document 9: 2005-213230) and the like.

  However, in the techniques described in Patent Documents 3 to 5, although the composition has excellent low-temperature stability, it is not only exposed to a low temperature, but also has no creamy property and no precipitation when left at a low temperature after storage over time. Further improvements have been desired. In the techniques of cited references 2 and 9, there is a possibility that the stability of long-term storage, particularly precipitation at low temperatures, may occur due to decomposition of the polymer compound, and when used in combination with other synthetic surfactants, washing mainly with fatty acid salts The refreshing feeling during rinsing, which is a characteristic of the agent, is reduced. Therefore, while taking advantage of the creamy property of the foam, which is a feature of fatty acid salt detergents, a general-purpose, inexpensive liquid body cleaner composition that ensures creamy foaming and stability even when exposed to low temperatures after storage over time. Was desired.

  The present invention has been made in view of the above circumstances, and is excellent in foam creamy immediately after preparation and after storage, and even when kept at a low temperature after storage over time, the precipitation of fatty acids is suppressed, and the liquid body has excellent storage stability. An object is to provide a cleaning composition.

The present inventor has conducted intensive investigations to achieve the above object, in the liquid personal cleansing compositions containing fatty acid salts, neutral or acidic dissociation constant pK _b of the amino group is from 9.10 to 10.90 By blending an amino acid and adjusting the pH of the liquid body cleaning composition to 9.0 to 11.0, it is excellent in creamy properties of foam even immediately after preparation and after storage, even when kept at a low temperature after storage over time, The present inventors have found that a liquid body cleaning composition that suppresses fatty acid precipitation and is excellent in storage stability can be obtained, and has led to the present invention.

Therefore, the present invention
[1]. (A) a fatty acid salt selected from laurate, myristate, and palmitate, an alkali metal salt, or a substituted or unsubstituted ammonium salt;
(B) A liquid body cleansing composition containing a neutral or acidic amino acid having an amino group dissociation index pK _b of 9.10 to 10.90 and a pH at 25 ° C. of 9.0 to 11.0 object,
[2]. (B) The liquid body cleaning composition according to [1], wherein the component is glycine, glutamic acid, aspartic acid, threonine, serine, glutamine, alanine, valine, isoleucine, leucine, tyrosine, or phenylalanine.
[3]. A liquid body cleanser composition according to [1] or [2], which is a non-aerosol foam cleanser.

  According to the present invention, there is provided a liquid body cleansing composition that has excellent foam creamy properties immediately after preparation and after storage, and suppresses precipitation even when stored at a low temperature after storage over time, and has excellent storage stability. Can do.

The present invention is described in detail below.
Compared with synthetic anion activators such as lauryl sulfate, etc., the liquid body detergent composition using fatty acid salts has excellent foam creaminess because the fatty acid salt in a dissociated state oriented in the foam film is It is presumed that it absorbs carbon dioxide in the air, lowers the pH, and becomes a water-insoluble fatty acid. The inventor has found that there is an optimum pH range in the composition for the fatty acid salt foam film to absorb carbon dioxide and form a solid film of fatty acid, which is between 9.0 and 11.0. I found out. When the pH is lower than this, sufficient foaming does not occur. This is presumably because the ratio between the dissociated fatty acid salt and the non-dissociated fatty acid is inappropriate. Moreover, when pH is higher than 11.0, creamy foam is hard to be obtained in the time which wash | cleans a body. This is expected because it takes time for the foam film to absorb carbon dioxide and form a solid film of fatty acid. Therefore, it is necessary that the pH of the preparation is between 9.0 and 11.0 in order to develop creamy foam in the liquid body detergent composition mainly composed of fatty acid salt (Test Examples 1 to 1 described later). 6).

  However, even if it is a liquid body cleaning composition that achieves creamy foam by adjusting the pH between 9.0 to 11.0 and improves storage stability at low temperature, the creaminess of the foam over time When the temperature drops or the temperature becomes low, precipitation may occur. The present inventor has found that the above-mentioned phenomenon over time is due to a decrease in pH, and that the pH is maintained at 9.0 to 11.0 not only immediately after preparation but also during storage, the foam creaminess and fatty acid salt It was clarified that it is necessary to suppress the precipitation of and maintain the storage stability.

There are two possible causes for this drop in pH during storage.
One is the generation of acid by decomposition of additives and the like. When a composition using a fatty acid salt as a main ingredient has an alkaline pH, decomposition of esters, aldehydes and the like is promoted. Examples of the additive containing an ester group include an ester oil used as a performance improver, a surfactant used as a foam-increasing agent, a fragrance, and the like (see test examples described later). Among these, in the liquid body cleaning composition, the fragrance is a component necessary for improving the commercial value, and is blended in most compositions. Usually, a perfume used in cosmetics is prepared by blending hundreds to thousands of perfume ingredients, but many of them have an ester structure, and the generation of carboxylic acid due to hydrolysis over time is observed. It cannot be completely prevented. Therefore, the effect of the present invention is particularly effective in a composition containing a fragrance component having an ester bond. Another cause of lowering pH is the absorption of carbon dioxide in the air.

Based on these findings, the liquid personal cleansing compositions containing fatty acid salt, dissociation index pK _b of the amino group is blended neutral or acidic amino acid is from 9.10 to 10.90, the liquid personal cleansing By adjusting the pH of the agent composition to 9.0 to 11.0, it is excellent in foam creamy immediately after preparation and after storage, and even when kept at a low temperature after storage over time, precipitation of fatty acids is suppressed and stored. It has been found that a liquid body cleanser composition having excellent stability can be obtained.

The liquid body cleansing composition of the present invention is selected from (A) a laurate, a myristate, and a palmitate, and a fatty acid salt that is an alkali metal salt or a substituted or unsubstituted ammonium salt; And a neutral or acidic amino acid having an amino group dissociation index pK _b of 9.10 to 10.90 and a pH of 9.0 to 11.0 at 25 ° C. is there.

  The component (A) of the present invention is selected from laurate, myristate, and palmitate, and is an alkali metal salt or a fatty acid salt that is a substituted or unsubstituted ammonium salt, one kind alone or two kinds The above can be used in appropriate combination, and a mixture such as coconut oil fatty acid salt can also be used. Examples of the alkali metal salt include potassium salt and sodium salt. Examples of the substituted or unsubstituted ammonium salts include amine salts, specifically, alkylammonium salts such as primary amine salts, secondary amine salts, and tertiary amine salts, monoethanolamine salts, diethanolamine salts, and triethanolamine. Examples thereof include hydroxyalkyl ammonium salts such as salts. Of these, alkali metal salts and hydroxyalkyl ammonium salts are preferred.

  (A) As for the compounding quantity of a component, 0.5-25 mass% is preferable in a liquid body cleaning composition, More preferably, it is 5-20 mass%. (A) If the amount of the fatty acid salt is too small, the creamy property of the foam may not be obtained. If the amount is too large, the viscosity may be too high.

Component (B) of the present invention is a neutral or acidic amino acid dissociation exponent pK _b of the amino group is from 9.10 to 10.90, can be used singly or in combination of two or more as appropriate. Examples of neutral or acidic amino acids having a dissociation index pK _b of 9.10 to 10.90 include aspartic acid, α-aminobutyric acid, 4-aminobutyric acid (GABA), alanine, β-alanine, alloisoleucine, isoleucine, ornithine , Canavanine, glycine, glutamine, glutamic acid, sarcosine, cysteine, citrulline, L-β- (3,4-dihydroxyphenyl) alanine (DOPA), serine, thyroxine, tyrosine, tryptophan, threonine, norvaline, norleucine, valine, 4- Examples include hydroxyproline, δ-hydroxyproline, phenylalanine, proline, homoserine, methionine, and leucine. The optical isomerism of amino acids is irrelevant to the effect of the present invention, and either D or L form may be a mixture. The value of pK _b in the present invention shall be in accordance with the value of the Chemical Handbook Fundamentals (Third Edition Japan Chemical Industry edited Maruzen).

Among these, glycine (9.78), glutamic acid (9.67), aspartic acid (9.60), threonine (9.12), serine (9.21), glutamine (9.13), alanine (9 .69), valine (9.62), isoleucine (9.68), leucine (9.60), tyrosine (10.07), phenylalanine (9.18) are preferable from the viewpoint of cost, stability, etc. Of these, glutamic acid is particularly preferable because it has a high pK _{b and a} strong buffering capacity, has a low influence on fragrance degradation, is easily supplied as a cosmetic raw material, has little coloration, and is inexpensive. Among these, when an amino acid containing a sulfur element such as cysteine or methionine is added, a sulfur-like odor may be generated when stored at a high temperature for a long time, and masking may be difficult.

Basic amino acids such as arginine and lysine exhibit a behavior as a counter ion of fatty acid, and a sufficient effect is not exhibited because there are molecules present in a form bound as a fatty acid salt. Further, when it dissociation constant pK _b of less than 9.10 of an amino group, lower the efficiency of capturing the generated protons, it is difficult to maintain the 9.0 or more is hardly pH region fatty at a low temperature to precipitate . When an amino acid other than (B) of the present invention is used, a strange odor may be generated during storage with high temperature over time, and brownish brown coloring may be observed.

  The preferred blending amount of component (B) is determined by the amount of carbon dioxide absorbed and the amount of esters to be hydrolyzed. Since the amino acid binds to the proton at a pH higher than the pH range where the fatty acid salt is changed to the fatty acid, the amount of fatty acid does not affect the required amount of amino acid. (B) The preferable compounding quantity of a component is 0.01-5 mass% from the optimal area | region of the mixing volume of the carbon dioxide in a normally used pump container, a regular type container, and a foam discharge container, and the compounding quantity of a fragrance | flavor. More preferably, it is 0.1-5 mass%. If the amount of amino acid is too small, the effect of stabilizing the pH may not be obtained. If the amount of amino acid is too large, discoloration or off-flavor over time may become a problem.

  In the liquid body cleaning composition of the present invention, other optional components can be appropriately blended within a range not impeding the effects of the present invention. Examples of optional components include surfactants other than component (A) such as amphoteric surfactants and nonionic surfactants, oils such as silicones and higher alcohols, lanolin derivatives, protein derivatives, water-soluble polymer compounds, Examples thereof include drugs such as vitamins, preservatives, pH adjusters, sequestering agents, ultraviolet absorbers, animal and plant extracts or derivatives thereof, and pigments. In addition, the addition amount of these arbitrary components can be mix | blended normal amount in the range which does not prevent the effect of this invention.

  The liquid body cleanser composition of the present invention has a pH at 25 ° C. of 9.0 to 11.0. As described above, in order to develop creamy foam and improve storage stability at a low temperature in a liquid body cleaner composition containing a fatty acid salt as a main ingredient, the pH of the liquid body cleaner composition is from 9.0. The range is 11.0. In addition, pH can be measured by inserting the electrode of a pH meter directly into a composition and reading the pH value after stabilizing using the method defined in the general test method of cosmetic raw material standards.

  The liquid body cleaning composition of the present invention can be filled into a pump or a foam discharge container. Among them, it is effective in a non-aerosol type foam cleaning agent that is easy to use. The non-aerosol type foam cleaning agent is a liquid body cleaning composition filled in a non-aerosol type foam discharge container, and the composition is discharged in the form of foam. Examples of the non-aerosol foam discharge container include the following. As a container of a type that mixes a certain amount of detergent composition with a certain amount of air and foams it, and discharges uniform fine bubbles through a sheet-like porous body (mesh), the head of the cap equipped with a pump mechanism is used with fingers. For example, a former pump that discharges bubbles by pressing, or a squeeze foamer that discharges bubbles by pressing the body of a soft container with fingers. The porous body of a container of a type that discharges foam through a sheet-like porous body (mesh) is preferably 100 mesh or more, more preferably 100 to 400 mesh, further preferably 200 to 350 mesh, and the number of the porous bodies is also 2 or more. Is preferable from the viewpoint of foam formation. In addition, as a type of container that discharges the detergent composition in a uniform and fine foam state through an injection port of a specific diameter, it has a mist dispenser that pushes down the nozzle part and discharges foamy foam, a foam ejection nozzle, and a trigger A trigger type spray container that discharges foamy bubbles by pressurizing the content liquid is used. With such a configuration of the non-aerosol type foam discharge container, the liquid body cleaning composition, which is the content liquid, is discharged with use and the air is replaced, and precipitates are generated as the pH decreases. Clogging is likely to occur. Therefore, the liquid body cleaning composition of the present invention is particularly effective in non-aerosol type foam cleaning agents (see test examples described later) since the liquid body cleaning composition of the present invention is effective in suppressing precipitates from the viewpoint of preventing defective discharge.

  It does not specifically limit as a liquid body washing | cleaning agent composition, It can be set as a face wash, a hand soap, a body soap, etc.

  There is no restriction | limiting in particular as a manufacturing method of the liquid body washing | cleaning agent composition of this invention, According to the objective, it can select suitably, Said (A), (B) component, arbitrary component, and water (liquid body washing | cleaning agent) The remaining composition) is mixed so that the whole composition is 100% by mass, and the pH at 25 ° C. is adjusted to 9.0 to 11.0. As a device for preparing the liquid body cleaning composition of the present invention, a stirring device provided with a plurality of stirring blades capable of being mixed with shear force, for example, a propeller, a turbine, a disper, etc., is desirable.

  When the liquid body cleaning composition of the present invention is used as a non-aerosol foam cleaning agent, the viscosity (5 ° C.) of the liquid body cleaning composition is preferably 100 mPa · s or less from the viewpoint of foam formation, and is 50 mPa. -S or less is more preferable. The lower limit of the viscosity is not particularly limited, but is 1 mPa · s. The viscosity was measured using an Ubbelohde viscometer based on the first method described in Cosmetic Raw Material Standards, General Test Viscosity Measurement Method.

  EXAMPLES Hereinafter, although an Example and a comparative example are shown and this invention is demonstrated concretely, this invention is not restrict | limited to the following Example. In the following examples, unless otherwise specified, “%” in the composition represents mass%, and the amount of each component in the table is an amount converted into a pure component.

[Test Examples 1 to 6]
A liquid body cleanser composition having the composition shown in Table 1 was prepared based on a conventional method, and the following method (1) foam creamy property (residual rate of foam over time) was determined.

[Test Example 7]
400 mL of the liquid body cleaning composition of Test Example 4 having a pH of 9.8 immediately after preparation was filled into a 600 mL non-aerosol foam discharge container (having a sheet-like porous body (mesh)). This was used at room temperature for 14 days, 5 pushes / day (15 mL / day). The pH (25 ° C.) of the composition when about half amount was used (after 14 days) was about 8.9, and decreased to 8.6 when almost the total amount was used (after 28 days). When the half-use product (pH 8.9) was used at 0 ° C, when the full-use product (pH 8.6) was used at 10 ° C, fatty acid deposits were clogged in the mesh part, resulting in poor discharge. .

[Test Example 8]
A composition excluding components containing esters was prepared from the liquid body cleansing composition of Experimental Example 5, and the pH immediately after the preparation was adjusted to 11.0. 400 mL of this composition was filled into a 600 mL non-aerosol foam discharge container (having a sheet-like porous body (mesh)). This was used at room temperature for 14 days, 5 pushes / day (15 mL / day). The pH (25 ° C.) of the composition when about half of the amount was used (after 14 days) was about 9.8, and almost 8.6 when the amount was used (after 28 days). When all the products used (pH 8.6) were stored at 0 ° C., precipitation of mixed crystals of lauric acid and myristic acid started 2 days later, and on the 5th day, the crystals grew to about 5 mm and the foaming property was lowered. And poor discharge from the pump container.

[Examples 1-5, Comparative Examples 1-5]
Liquid body cleansing compositions having the compositions shown in Tables 2 and 3 were prepared according to conventional methods, and 400 mL each was filled into a pump container having a 500 mL dispenser. This liquid body cleansing composition was stored at room temperature (25 ° C.) and 45 ° C., pH was measured, and the following evaluation was performed. The 45 ° C. storage is a method usually used as an alternative storage condition for room temperature long-term storage.

(1) Evaluation of creamy property of foam (foam remaining rate with time)
Epton Tube Method 2 g of the liquid body cleaning composition and 20 g of tap water were placed in a 100 mL Epton tube and bubbled up and down at a speed of 30 times per minute. The initial foam height (mL) at this time and the foam height (mL) after being allowed to stand for 15 minutes were measured, and the residual foam ratio with time was calculated by the following formula.
Bubble height after standing for 15 minutes (mL) / initial bubble height (mL) × 100 = bubble residual rate over time (%)
In the sensory evaluation, the creamy property of the foam and the residual foam ratio with time are highly correlated, and the higher the residual foam ratio with time, the higher the foam density and the higher the creaminess. Therefore, the creamy property of the foam in the present invention is evaluated by the foam remaining rate with time obtained by the above method.
When the residual ratio with time exceeds 60%, the creaminess in the sensory evaluation is very good. If it is 50 to 60%, the creaminess is good, and if it is about 50 to 40%, neither can be said. If it is lower than 40%, the creaminess is low.

(2) Stability when stored at low temperature after storage over time (precipitation at low temperature)
