DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a cleaning agent having a massage effect and a cleansing effect,
More specifically, the present invention relates to a cleaning agent which has excellent storage stability, smoothes the skin, has less slimy feeling after washing, and is excellent in usability such as washing off and usability.

[0002]

2. Description of the Related Art Generally, a cleansing agent having a massage effect is applied to the skin and massaged to promote blood circulation, prevent aging of the skin, and wash and remove waste products from the skin. is there. Conventional cleaning agents having a massage effect and a cleaning effect include, for example, a scrub agent, a water-insoluble clay mineral or a polymer particle having a specific Mohs hardness or a specific particle size, and a blood circulation promoting effect or skin There has been proposed one having an effect of removing old keratin and the like in addition to a cleaning effect (see, for example,
JP-A-238008, JP-A-63-150216, JP-A-1-190622, JP-A-2-151
No. 693, etc.).

In addition, since inorganic salts have the effect of activating the metabolic activity of the human body, the addition of granular inorganic crystal salts has the effect of removing old dead skin and the like and has a massage effect. Are disclosed (for example, JP-A-1-67235, JP-A-2-2-2).
4398, JP-A-3-123732, JP-A-6-123569, etc.).

[0004]

However, conventional cleaning agents having a massage effect, although having a blood circulation promoting effect, may cause precipitation of water-insoluble clay minerals, or have a sticky and insufficient feeling of use. There are problems such as insufficient effect on usability such as smoothness of skin and refreshing finish, and inconvenience in usability such as difficulty in rinsing, and the solution has been eagerly desired.

The present invention has been made in view of the drawbacks and problems of a conventional cleaning agent having a massage effect.
An object of the present invention is to provide a cleaning agent which has a blood circulation promoting effect, an excellent cleaning effect, an excellent feeling in use, and a good storage stability.

[0006]

That is, the gist of the means adopted by the present invention to solve the above-mentioned problems is as described in the appended claims.

[0007] According to the invention described in each of the claims adopting such a configuration, since the granular solid soap is contained in the liquid or kneaded detergent, the granular solid soap exerts a massage effect. And an effect of removing dead skin cells and the like can be exerted.

[0008] Liquid or kneaded detergents and granular solid soaps all have a detergency, and these are both soluble in water, so that the detergency of both can act additively or synergistically. Can be. In other words, it is possible to exhibit an excellent cleaning effect, improve the feeling of use such as being less sticky and easier to wash off, and furthermore, as in the case of using conventional scrubbing agents, water-insoluble clay minerals or polymer particles, a sewage pipe. Almost no clogging.

[0009] In particular, the invention according to claims 3 and 4 is characterized in that, in a medium of a liquid or a kneaded detergent (particularly in water), a concentration of a salt or the like necessary for salting out a granular solid soap is used. Since it is configured so as to incorporate an inorganic salt, the granular solid soap does not dissolve in the medium (water portion) of the liquid or kneaded detergent and disappears (the long-term storage is possible. Even if the solid soap is a salt (soap) of a higher fatty acid that is easily soluble in water, it can be stably stored for a long period of time while containing these almost uniformly and stably.

[0010]

Next, the cleaning agent according to the present invention is
This will be described in more detail.

In the present specification, the “higher fatty acid” refers to
Any of them can be used irrespective of the number of constituent carbon atoms or the type of a salt thereof.
Is a higher fatty acid. More specifically, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid,
Saturated linear fatty acids represented by stearic acid and arachidic acid, myristoleic acid, palmitooleic acid, oleic acid, elaidic acid, eicosenoic acid, linoleic acid, linolenic acid, eicosadienic acid, eicosatrienoic acid, arachidonic acid, etc. Unsaturated linear fatty acids represented by, for example, hydroxydodecanoic acid, hydroxytetradecanoic acid, hydroxyhexadecanoic acid, saturated hydroxy fatty acids represented by hydroxyeicoic acid and the like, unsaturated hydroxy fatty acids represented by lysine oleic acid and the like, Isolauric acid, isomyristic acid, isopalmitic acid, isostearic acid,
Isoacids represented by isoarachidic acid and the like can also be used. In addition, 9-methylundecanoic acid, 11-
Methyltridecanoic acid, 11-methylpentadecanoic acid, 1
Anteisoic acid typified by 5-methylheptadecanoic acid and the like can also be used, but here, it is classified as isoacid.

Next, more specific examples of the "base component" to be combined with the higher fatty acid include alkali metals such as sodium and potassium, alkaline earth metals such as calcium and magnesium, ammonia, and monoethanolamine. And organic salts represented by diethanolamine, triethanolamine and the like.

Next, as the ionic surfactant used in the present invention, anionic, cationic, amphoteric surfactants and the like can be used, and there is no particular limitation.

Among the ionic surfactants used in the present invention, other than the fatty acid soap, anionic surfactants include POE alkyl ether carboxylate, α-olefin sulfonate and higher fatty acid ester sulfonate. ,
Dialkyl sulfosuccinate, higher fatty acid amide sulfonate, alkyl allyl sulfonate, higher alcohol sulfate, POE alkyl ether sulfate, glycerin fatty acid ester sulfate, higher fatty acid alkylolamide sulfate, alkyl phosphoric acid Ester salts, acyl glutamates, acyl sarcosine salts, acyl amino acid salts such as acyl-β-alanine,
Collagen hydrolysate acyl compounds and the like can be applied, all of which include alkali metal salts such as sodium and potassium, alkaline earth metal salts such as calcium and magnesium, ammonium salts, monoethanolamine, diethanolamine, triethanolamine and the like. Organic amine salts, basic amino acid salts such as L-lysine and the like can be used.

The cationic surfactant used in the present invention includes alkylamine salts, polyamine fatty acid salts, alkanolamine fatty acid salts, alkyl quaternary ammonium salts,
Alkyl trimethyl ammonium salts and the like can be used.

The amphoteric surfactant used in the present invention includes:
Amino acid type, betaine type, sulfate ester type, sulfonic acid type, phosphate ester type amphoteric activator and the like can be used. The amount of these ionic surfactants is not particularly limited, but is preferably 2% by weight or more, more preferably 5% by weight.
That is all. When the content is less than 2% by weight, it is difficult to obtain a satisfactory detergency and foaming property as a detergent.

Furthermore, in addition to the ionic activator, an amine oxide and a fatty acid diethanolamide can be blended to improve the foaming property and to give an appropriate viscosity. In addition, the combined use with a pearlescent agent such as fatty acid glycol diester or the like and a thickener such as hydroxyethylcellulose make it possible to improve long-term stability over time.

The "inorganic salt" used in the present invention is dissolved in a medium (particularly, a water portion) of a liquid or kneaded detergent in order to salt out granular solid soap. The insolubilized part is constituted by blending over the saturation concentration,
This does not aim to obtain a massage effect or the like. More specifically, salt, potassium chloride, ammonium chloride, sodium sulfate, potassium sulfate, ammonium sulfate, sodium carbonate, potassium carbonate, ammonium carbonate, sodium bicarbonate, potassium bicarbonate, ammonium bicarbonate and the like can be exemplified.

In the present specification, the term "salt" means a wide concept including, for example, rock salt and natural salt purified from seawater, and the simple substance of sodium chloride is, of course, such as bittern. It also includes sodium chloride and the like contained therein.

By the way, when magnesium sulfate or magnesium nitrate is used instead of (or in addition to) sodium chloride, a rust-preventing action on stainless steel is obtained, and corrosion of a water distribution pipe, a stainless steel bathtub, and the like can be prevented. .

Furthermore, when calcium chloride is added instead of (or in addition to) sodium chloride, the final product can be prevented from freezing, and when magnesium chloride, calcium nitrate, or calcium acetate is added, the final product can be stabilized, When aluminum chloride, aluminum sulfate, or aluminum nitrate is blended, an astringent action on the skin is obtained, and when magnesium acetate is blended, a deodorizing action is obtained.

In addition, a rust-preventing effect can be obtained by a formulation containing magnesium nitrate instead of (or in addition to) salt, and rust-prevention of piping materials and bathtubs can be achieved.

Furthermore, when an inorganic or organic alkali salt of an amino acid represented by sodium glutamate or the like, an inorganic or organic acid salt of an amino acid, or calcium lactate is blended, the usability such as a feeling of touch and moisturizing skin is improved. When urea is added, the moisture retention can be improved.

In addition to the above components, for example, wetting agents, coloring agents, preservatives, feel improvers, perfumes,
A bactericidal or antibacterial agent, an anti-inflammatory agent, an ultraviolet absorber or the like can be used as long as the effects of the present invention are not impaired.

The detergent according to the present invention can be widely used as a skin cleanser such as a whole body cleanser and a face wash, and as a dishwashing detergent, for example.

EXAMPLES Next, the present invention will be described in more detail with reference to more specific examples. However, all of these prescriptions are merely exemplifications and are within the scope not changing the gist of the invention described in each claim. It can be modified in various ways. In addition, all compounding amounts are weight%.

First, a granular solid soap contained in a liquid or kneaded detergent can be produced by the following methods. A method in which a solid soap produced according to a conventional method is dried by a forced drying method such as a vacuum drying method, and then crushed and, if necessary, sieved into a granular solid soap having a desired particle size. . A method in which a solid soap (salt of higher fatty acid) produced according to a conventional method is dried by a spray drying method, and the obtained granular solid soap is sized to a desired particle size, if necessary. For example, a method in which a solid soap (salt of higher fatty acid) produced according to a conventional method is immersed in a high-concentration salt solution. According to this method, the water contained in the solid soap can be moved toward the high-concentration salt solution, whereby the solid soap can be hardened.
For example, a method of neutralizing a mixture of stearic acid and lauric acid with sodium hydroxide to obtain a mixed solution, for example, adding salt (inorganic salt) and subjecting to a salting-out treatment. According to this method, the sodium salt of stearic acid is salted out at a relatively low concentration of sodium chloride, whereas the sodium salt of lauric acid is hardly salted out at a low concentration of sodium chloride and remains dissolved. A solid soap containing sodium stearate as a main component was added to a liquid sodium laurate (detergent) containing a salt (inorganic salt) having a concentration higher than that required for salting out the solid soap. The equivalent of a cleaning agent can be manufactured.

First Example <Prescription 1> Lauric acid 10.0 50% by weight potassium hydroxide 5.6 Salt 4.0 Soda soap 1.0 Ion-exchanged water 79.4 A predetermined amount of lauric acid was added to ion-exchanged water. Dissolve, neutralize with 50% by weight potassium hydroxide to make potassium salt of lauric acid, and slowly add salt and soda soap with stirring. Then, although potassium laurate (potassium soap) does not salt out at such a salt concentration, it has a salt concentration sufficient for salting out soda soap. Therefore, in semi-solid (kneaded) potassium laurate, A cleaning agent in which solid soda soap is uniformly and stably dispersed as particles can be obtained.

Second Example <Formulation 2> Amidopropyl laurate-betaine solution (effective content: 30%) 30.0 Salt 20.0 Soda soap 1.0 Deionized water 49.0 Sufficient for salting out soda soap Amide betayl laurate solution (effective 30%)
Thus, a detergent in which solid soda soap is uniformly and stably dispersed as particles in a liquid detergent containing as a main component is obtained.

Although the detergent of the third embodiment is not shown as a specific formulation, it does not contain an inorganic salt for salting out in a liquid or kneaded solution of a higher fatty acid salt (soap solution). ,
For example, it contains only a poorly water-soluble metal soap such as a calcium soap or a magnesium soap.

When the detergents of the above embodiments are used for bathing, for example, an excellent washing action and a massage effect by solid soda soap are obtained. It does not clog the usability or the water pipe.

[0032]

As described above, for example, soda soap (solid soap) can be dispersed in a liquid or kneaded detergent in a stable state for a long period of time in the form of granules.
In addition to the excellent cleaning effect, it can be provided at a low cost as a cleaning agent which is extremely effective, particularly, a massage effect by particles of solid soap is obtained.
