Description

  The present invention relates to a marble-like frame kneaded soap having a beautiful appearance and a method for producing the same.

Conventionally, in order to beautify the appearance of soap, coloring ingredients such as dyes and pigments are added to the soap base to color the entire soap. In recent years, marble soaps such as marble patterns and ink-sink patterns have been proposed as soaps having a more beautiful appearance and higher palatability (see, for example, Patent Document 1). Such marble-like soap is manufactured by kneading a soap base serving as a substrate base and a soap base serving as a marble base of a different color.
JP 2001-311098 A (Claims and paragraph 0023)

  In such a method, it can be produced relatively easily by the mechanical kneading method, but a beautiful marble tone soap cannot be obtained by the frame kneading method. Since the freezing point of the soap base used in the frame kneading method is usually as low as 40 to 43 ° C., the soap base has high fluidity (low viscosity) and is difficult to solidify. Because it is too mixed and slow to solidify, a beautiful marble soap cannot be obtained.

  The present invention is intended to solve the above-described points, and an object of the present invention is to provide a marble-like frame kneaded soap having a beautiful appearance and a method for producing the same.

  As a result of various investigations to achieve the above-mentioned problems, the inventors of the present invention have produced a marble-like soap by the frame kneading method, and the freezing point of the soap base used, the first soap base after filling the mold, By setting the cooling temperature and the filling temperature of the second soap base to be filled in a specific range, it has been found that a marble-like soap with a beautiful appearance can be obtained even by the frame kneading method. The invention has been completed.

  That is, the present invention is a frame kneaded soap characterized by mixing two or more soap bases colored in different colors having a freezing point of 44 to 55 ° C. so as to form a marble pattern.

  As a preferred embodiment, the alcohol content of the soap base is preferably 15% by weight or less. Moreover, it is preferable that one color is white among soap bases of two or more colors.

The present invention is also a production method for obtaining the above marble-like frame kneaded soap,
(A) filling a mold with a first soap base having a freezing point of 44 to 55 ° C., which has been heated and melted;
(B) cooling the filled first soap base to a temperature 10-15 ° C. above its freezing point;
(C) A first soap base having a color different from that of the first soap base and having a freezing point of 44 to 55 ° C. is cooled at a temperature 6 to 10 ° C. higher than the cooled first soap base . Filling the soap base;
(D) obtaining marbled framed soap by cooling the first and second soap bases until solidified ;
It is the manufacturing method of the frame kneading soap characterized by the above-mentioned.

  As a preferred embodiment, the alcohol content of the first and second soap bases is preferably 15% by weight or less. Moreover, it is preferable that one of the 1st and 2nd soap bases is white.

The present invention further provides a production method for obtaining the above marble-like frame kneaded soap,
(A) filling a mold with a first soap base having a freezing point of 44 to 55 ° C., which has been heated and melted;
(B) cooling the filled first soap base to a temperature 10-15 ° C. above its freezing point;
(C) A first soap base having a color different from that of the first soap base and having a freezing point of 44 to 55 ° C. is cooled at a temperature 6 to 10 ° C. higher than the cooled first soap base . Filling the soap base;
(D) cooling the filled second soap base to a temperature 12-16 ° C. above its freezing point;
(E) A second soap base having a color different from that of the second soap base and having a freezing point of 44 to 55 ° C. cooled at a temperature 5 to 9 ° C. higher than that of the cooled second soap base . Filling the soap base;
(F) obtaining marbled framed soap by cooling the first, second and third soap bodies until solidified ;
It is the manufacturing method of the frame kneading soap characterized by the above-mentioned.

  Here, as a preferred embodiment, the alcohol content of the first, second and third soap bases is preferably 15% by weight or less. Moreover, it is preferable that one of the 1st, 2nd and 3rd soap bases is white. The first soap base and the third soap base are preferably the same color.

According to the manufacturing method of the present invention, the cooling temperature of the first soap base is set to a temperature 10 to 15 ° C. higher than the freezing point, and the filling temperature of the second soap base filled thereon is set to the cooling temperature. The temperature is set 6 to 10 ° C. higher than the first soap base . When the cooled first soap base is filled with the heated and melted second soap base, both the first and second soap bases are at a temperature higher than the freezing point, so that they are in a molten state (ie, fluidity). It begins to mix. At this time, since the temperature from the freezing point of the second soap base is higher than the temperature from the freezing point of the first soap base, their fluidity is different, and the second soap base is the first soap base. Is in a higher state. That is, since the first soap base having lower fluidity is filled with the second soap base having higher fluidity, they are mixed but not completely mixed.

  Moreover, since the freezing point of the first and second soap bases is higher than that of the soap base used in the ordinary frame kneading method (that is, 44 to 55 ° C.), the fluidity in the molten state is lower than usual and the solidification is performed. Is faster than usual. Therefore, when cooled after filling the second soap base, the first soap base and the second soap base are solidified without being completely mixed. As a result, the first soap base and the second soap base are mixed appropriately and non-uniformly, and the color changes irregularly, that is, a marble pattern.

  Hereinafter, the present invention will be described in detail. The frame kneaded soap of the present invention is obtained by mixing two or more soap bases colored in different colors having a freezing point of 44 to 55 ° C. so as to form a marble pattern. Here, the “marble pattern” is a pattern in which two or more soap bases colored in different colors are mixed unevenly and the color changes irregularly, such as a marble pattern, Appears like an ink-sink pattern. In the present invention, the “marble pattern” may be formed on the whole soap or may be partially formed. However, the appearance of a more “marble pattern” is more beautiful. preferable.

  In the manufacture of the frame kneaded soap of the present invention, first, a soap base having a freezing point of 44 to 55 ° C. is used. Here, if the freezing point of the soap base is less than 44 ° C., the fluidity is high and it is difficult to solidify, so the soap base is too mixed. On the other hand, if the freezing point of the soap base exceeds 55 ° C., the fluidity is low and it is easy to solidify, so that the soap base is difficult to mix. Therefore, in both cases, a beautiful marble pattern cannot be formed even if a marble-like soap is manufactured by the frame kneading method. The freezing point of the soap base is preferably 45 to 49 ° C.

  The soap base used in the present invention first contains a fatty acid alkali salt as a main component. Here, the fatty acid of the fatty acid alkali salt is a linear or branched, saturated or unsaturated fatty acid having 8 to 24 carbon atoms, and preferably having 12 to 18 carbon atoms. Specific examples of suitable fatty acids include saturated fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, and isostearic acid; unsaturated fatty acids such as oleic acid, linoleic acid, linolenic acid, and ricinoleic acid; and mixtures thereof. Examples include coconut oil fatty acid, palm oil fatty acid, palm kernel oil fatty acid, beef tallow fatty acid, and hardened tallow fatty acid.

  Examples of the alkali of the fatty acid alkali salt include alkali metals such as sodium and potassium; alkaline earth metals such as calcium and magnesium; organic amines such as ethanolamine (mono-, di- and tri-) and N-methyltaurine alkali salts Among them, sodium and potassium are preferably used.

  Said fatty acid alkali salt can be used individually or in combination of 2 or more types.

  The amount of the fatty acid alkali salt used is preferably 10 to 60% by weight, particularly preferably 25 to 40% by weight in the soap base. If the amount of the fatty acid alkali salt is too large, the freezing point of the soap base becomes too high. On the other hand, if the amount is too small, the freezing point of the soap base becomes too low.

  As soap base components other than the above-mentioned fatty acid alkali salts, components usually blended in solid soap soap bases can also be blended. For example, the following components may be mentioned, and these components are blended within a range where the freezing point of the soap base does not deviate from 44 to 55 ° C.

Anionic surfactants such as N-long chain acylamino acid salts, alkyl sulfate salts, polyoxyethylene alkyl ether sulfates, hydroxyalkyl ether carboxylates;
Amphoteric surfactants such as imidazoline amphoteric surfactants and betaine amphoteric surfactants;
Nonionic surfactants such as polyoxyalkylene alkyl ether, polyoxyalkylene glyceryl ether, polyoxyalkylene fatty acid ester, sucrose fatty acid ester, alkyl glucoside, maltitol hydroxy aliphatic ether;
Cationic surfactants such as trimethylalkylammonium chloride;
Polyols such as glycerin, diglycerin, 1,3-butylene glycol, ethylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, sucrose, sorbit;
Chelating agents such as edetate.

  Moreover, although alcohol, such as water and ethanol, can also be mix | blended as a soap base component, in order to set a freezing point to 44-55 degreeC, especially alcohol is preferably 15 weight% or less, More preferably, it is 3-10 weight%. It is good to do.

  The soap base is prepared by heating and mixing the above components, that is, fatty acid alkali salt, other known soap base components, water, alcohol and the like. A fatty acid alkali salt may be prepared from a fatty acid during this step.

  The soap base is colored, but in the present invention, it is preferably colored with a pigment. In the case of dyes, movement (color transfer) is observed over time in soap, and the initial pattern is not maintained. Examples of the pigment used in the present invention include inorganic pigments such as iron oxide, bitumen, ultramarine, chromium oxide, chromium hydroxide, carbon black, titanium oxide, zinc oxide, talc, kaolin, mica, calcium carbonate, and magnesium carbonate. Resol Rubin BCA (Red 202), Lake Red C (Red 203), Lake Red CBA (Red 204), Resor Red (Red 205), Resor Red CA (Red 206), Resor Red BA (Red 207); No.), Risor Red SR (Red No. 208), Brilliant Lake Red R (Red No. 219), Deep Maroon (Red No. 220), Toluidine Red (Red No. 221), Permaton Red (Red No. 228), Permanent Orange ( Daidai Color No. 203), Bench Gin Orange G (Daidai Color) 04), Bench Ginero G (Yellow 205), Brilliant Fast Scarlet (Red 404), Permanent Red F5R (Red 405), Hansa Orange (Daidai 401), Hansa Yellow (Yellow 401), Phthalocyanine Organic pigments such as blue (blue 404); and the like are used, and these are used alone or in combination of two or more, and are colored to a desired color. This coloring may be performed during the preparation of the soap base or after the preparation.

  In addition to the above soap base, components other than the soap base can be blended according to the desired concept. For example, assembly, peonies, iris, horsetail, aloe, chamomile, eucalyptus oil, dipotassium glycyrrhizinate Plant extract ingredients such as tranexamic acid, tricroic acid, triclocarban, vitamin E, vitamin B12, xylitol, etc .; moisturizing ingredients such as hyaluronic acid, trehalose, oligosaccharide, sodium chondroitin sulfate, collagen, hydroxyproline, proline; Examples include whitening ingredients such as extract, ellagic acid, ascorbic acid glucoside, vitamin C; horny clear ingredients such as trimethylglycine, glycine, L-serine, crystalline cellulose, polyethylene powder, and other flavors.

  The blending amount of these components is usually a very small amount (1.0% by weight or less), but it is necessary that the freezing point does not deviate from 44 to 55 ° C. after blending in the soap base. These components may be blended at the time of preparing the soap base or after the preparation.

  The frame kneaded soap of the present invention is produced by the following method by a frame kneading method using soap bases of two or more colors that are prepared as described above and are colored in different colors.

  First, the first soap base having a freezing point of 44 to 55 ° C., which has been heated and melted, is heated and melted and filled in a predetermined mold. The temperature for this heat-melting is not particularly limited, but it is preferably a temperature that is 17 to 25 ° C. higher than the freezing point, particularly 18 to 22 ° C. higher than the freezing point.

  The filled first soap base is then cooled to a temperature 10-15 ° C. above its freezing point, preferably 12-14 ° C. above its freezing point. If the cooling temperature is too low, even if the second soap base is filled thereon, they are difficult to mix with each other. On the other hand, if the cooling temperature is too high, if the second soap base is filled thereon, they are too mixed with each other. The method for cooling the first soap base is not particularly limited, but it is preferably left to cool because it can be easily controlled to a desired temperature.

  Subsequently, the second soap base is filled. The color of the second soap base is not particularly limited as long as it is different from that of the first soap base, but one of the first and second soap bases is white because a more beautiful marble pattern can be obtained. It is preferable that In addition, for this second soap base, this soap base component may be the same as the first soap base component or may be different as long as the freezing point is 44 to 55 ° C., but is the same from the viewpoint of workability. It is preferable that In this case, it is preferable that the first soap base and the second soap base are prepared together, divided into two predetermined amounts, and each soap base is colored to a desired color. At this time, components other than the soap base components as described above can be blended according to the desired concept.

  About the usage-amount of a 2nd soap base, it selects suitably so that it may become a desired marble pattern, but a 1st soap base: 2nd soap base is 1: 1-3, especially 1: 1 by weight ratio. It is preferably ˜2.

The second soap base is filled into the cooled first soap base. When the filling temperature of the second soap base is too low, it becomes difficult to mix with the first soap base. On the other hand, if the filling temperature of the second soap base is too high, the first soap base is too mixed with the first soap base. Filling temperature of the second soap base is viewed from the cooling temperature of the first soap base, and 6 to 10 ° C. higher temperatures. Moreover, it is preferable to fill the second soap base so as to be along the wall surface of the mold.

  Finally, the first and second soap bases are cooled until solidified. The cooling method at this time is not particularly limited, but water cooling is preferable from the viewpoint of workability.

  In the above description, the production of the two-colored marble-style frame kneaded soap using the first and second soap bases has been described. However, the first, second, and third soap bases are used to produce the marble-style frame kneaded soap. It can also be manufactured. After filling the second soap base, it is cooled to a temperature 12-16 ° C. above its freezing point, preferably 13-15 ° C. above its freezing point. The reason for this cooling temperature is the same as in the case of the first soap base.

  Next, a third soap base is filled. The color of the third soap base is not particularly limited as long as it is different from the second soap base. Moreover, it is preferable that one of the 1st, 2nd and 3rd soap bases is white from the point from which a more beautiful marble pattern is obtained. Further, in order to obtain a two-color marble pattern, the first soap base and the third soap base may be the same color. In this case, rather than using the first and second soap bases as described above, A marble pattern can be formed in a wider range. Further, for this third soap base, this soap base component may be the same as the first and second soap base components or may be different as long as the freezing point is 44 to 55 ° C. Therefore, it is preferable that these are the same. In this case, it is preferable that the first to third soap bases are prepared together, divided into three predetermined amounts, and each soap base is colored in a desired color. At this time, components other than the soap base components as described above can be blended according to the desired concept.

  The usage amount of the third soap base is appropriately selected so as to obtain a desired marble pattern. For example, when the first and third soap bases are the same color, the first and third soaps are in a weight ratio. Total amount of substrate: It is preferable that the second soap substrate is 1: 1 to 3, particularly 1: 1 to 2.

Then, the heated and melted third soap base is filled in the cooled second soap base. The reason for this filling temperature is the same as in the case of the second soap base. Filling temperature of the third soap base is viewed from the cooling temperature of the second soap base, 5 to 9 ° C. higher temperatures, and preferably 5 to 7 ° C. higher temperatures. The filling of the third soap base is preferably performed along the wall surface of the mold.

  Finally, the first, second, and third soap bases are cooled until they are solidified. The cooling method at this time is not particularly limited, but water cooling is preferable from the viewpoint of workability.

  After solidification, it is taken out from the mold and, if necessary, ripened and shaped as necessary, to obtain a marble-like frame kneaded soap of the final product.

  EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated in more detail, this invention is not limited to these Examples.

  A soap base was prepared in the following manner according to the formulation shown in Table 1. To 5 parts of lauric acid, 10 parts of myristic acid, 3 parts of palmitic acid and 7 parts of stearic acid, 15 parts of glycerin, 2 parts of sorbit, 5 parts of polypropylene diglyceryl ether, 5 parts of ethanol and 14.9 parts of ion-exchanged water are added. After heating and dissolving at 60 ° C., the mixture was neutralized by adding 10 parts of caustic soda (48%), and further 13 parts of sugar, 2 parts of 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, 8 parts of polyoxyethylene hydrogenated castor oil was added and heated and stirred at 70 ° C. to obtain a soap base. In addition, about the comparative example 2, in the said prescription, glycerin was changed into 4 parts and ethanol as 16 parts, and the comparative example 3 changed the prescription into 20 parts and glycerol as 0 parts.

  The soap base was divided into two parts, and 0.1 part of titanium oxide was added to one side and mixed to prepare a white first soap base (50 g). On the other hand, 0.1 part of red iron oxide was added and mixed to prepare a red second soap base (50 g).

  For Example 1 and Comparative Examples 2 and 3, the white first soap base was further divided into two to obtain a first soap base (25 g) and a third soap base (25 g).

このようにして得られた石鹸素地から、表２に示す条件により枠練り石鹸を製造した。なお、第２の石鹸素地（および第３の石鹸素地）の充填は、図１に示すように、成形型の充填口を約４５℃に傾けて、壁面に沿わせるように行った。得られた枠練り石鹸について、以下の評価基準にて目視により外観を評価した。また、石鹸素地の凝固点は、以下の方法により行なった。それらの結果を表２に示す。

From the soap base thus obtained, framed soap was produced under the conditions shown in Table 2. The filling of the second soap base (and the third soap base) was performed so that the filling port of the mold was inclined at about 45 ° C. and along the wall surface, as shown in FIG. About the obtained frame kneaded soap, the external appearance was evaluated visually according to the following evaluation criteria. Moreover, the freezing point of the soap base was performed by the following method. The results are shown in Table 2.

＜評価方法＞
１．凝固点
石鹸素地を樹脂製のコップに流し込んだ後、水銀温度計を用いてゆっくりと攪拌し、温度の低下によりその攪拌が困難なるまで固化した時点の温度を測定し、その温度を凝固点とした。

<Evaluation method>
1. Freezing point After pouring the soap base into a resin cup, the mixture was slowly stirred using a mercury thermometer, and the temperature at the time of solidification until the stirring was difficult due to a decrease in temperature was measured.

2. Appearance of soap ◎: A marble pattern is formed on the whole soap ○: A marble pattern is formed on 2/3 or more of the soap △: A marble pattern is formed on 1/3 or less of the soap less than 2/3 Yes: The marble pattern is hardly formed (less than 1/3) on the soap.

  As apparent from Table 2, the frame-kneaded soap obtained in Example 1 has a freezing point of the soap base of 44 to 55 ° C., and the cooling temperature of the first and second soap bases (at the time of filling the next layer) Since the base material cooling temperature and the filling temperature of the second and third soap bases are set to the predetermined temperatures, it can be seen that these soap bases are mixed appropriately and unevenly to form a beautiful marble pattern. The same applies to the frame kneaded soap obtained in Example 2.

  On the other hand, in the frame kneaded soap obtained in Comparative Example 1, since the cooling temperature of the first soap base when filling the second soap base was too high, these were too mixed and almost pink throughout. It became a color and the marble pattern was not formed.

  In the frame kneaded soap obtained in Comparative Example 2, since the freezing point of the soap base was too low, the cooling temperature of the first and second soap bases (base cooling temperature when filling the next layer) and the second and third soaps Even if the filling temperature of the substrate was set to a predetermined temperature, they were mixed too much and became almost pink throughout, and a marble pattern was not formed.

  In the frame kneaded soap obtained in Comparative Example 3, the freezing point of the soap base was too high, so the first to third soap bases were hardly mixed together, resulting in a three-layer pattern with a blurred boundary surface.

  The frame kneaded soap of the present invention, in which two or more soap bases colored in different colors are mixed together to form a marble pattern, is a very beautiful appearance and highly palatable soap. It will increase motivation.

In an Example, it is a figure which shows the state filled with soap base.
