Description

  The present invention relates to a multicolor laminated 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, a soap in which soap bases of two or more colors are laminated is also known as a soap having a more beautiful appearance and higher palatability. In such a laminar type soap, in the frame kneading method, first, a heat-melted soap base of a certain color is filled into a mold, solidified, and once taken out from the mold and cut in half, one side is cut. It is manufactured by returning to a mold and filling and solidifying soap bodies of different colors heated and melted thereon. The soap obtained by such a method has a problem that deformation or cracking occurs during aging. Also, since the boundary of the lamination is clear, it is artificial and it is not beautiful.

As another method, it has been proposed that soap bases having different specific gravity and color in a molten state are sequentially filled in the same container and simultaneously cooled and solidified (for example, see Patent Document 1).
Japanese Patent Publication No. 6-94560 (Claims and Production Examples)

  However, in the method of laminating using the specific gravity difference as described above, the soap bases are actually mixed with each other, and it is difficult to obtain a laminated product.

  The present invention is intended to solve the above-described points, and an object of the present invention is to provide a beautiful multicolor laminated frame kneaded soap having a clear boundary between layers by a frame kneading method and a method for producing the same. There is.

  As a result of various investigations to achieve the above-mentioned problems, the inventors of the present invention have found that in producing multicolor laminated soap by the frame kneading method, the freezing point of the soap base used, the first soap base after filling into the mold, and It was found that by setting the cooling temperature and the filling temperature of the second soap base to be filled in a specific range, a multicolor laminated soap having a beautiful appearance with unclear laminate boundaries can be obtained. The invention has been completed.

  That is, according to the present invention, soap bases of two or more colors colored in different colors having a freezing point of 44 to 55 ° C. are laminated, and the boundary between the layers is in a state where the soap bases are mixed and blurred. It is a multi-colored laminated frame kneaded soap.

  As a preferred embodiment, the alcohol content of the soap base is preferably 15% by weight or less.

The present invention is also a method for producing the above multicolor laminated 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 7-2 ° C. below its freezing point;
(C) A second soap base having a color different from that of the first soap base and having a freezing point of 44 to 55 ° C. is filled into the cooled first soap base at a temperature 11 to 21 ° C. higher than the freezing point. ;
(D) cooling the first and second soap bodies until solidified;
This is a method for producing a multicolor laminated frame kneaded soap.

  As a preferred embodiment, the alcohol content of the first and second soap bases is preferably 15% by weight or less.

  According to the production method of the present invention, the cooling temperature of the first soap base is set to a temperature lower by 7 to 2 ° C. than the freezing point, and the filling temperature of the second soap base filled thereon is set higher than the freezing point. Is also set to a temperature 11 to 21 ° C higher. When the cooled first soap base is filled with the second soap base heated and melted, the temperature of the first soap base is about 7 to 2 ° C. lower than the freezing point. It is not completely solidified. Since the temperature of the second soap base is 11 to 21 ° C. higher than the freezing point, filling the cooled first soap base near the boundary between the first soap base and the second soap base The first soap base rises in temperature and melts and begins to mix with the second soap base.

  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. Accordingly, when cooling is performed after filling the second soap base, the mixture of the first soap base and the second soap base remains in the vicinity of the boundary and solidifies. As a result, the boundary between the first soap base and the second soap base is mixed and blurred.

  Hereinafter, the present invention will be described in detail. The multi-color laminated frame kneaded soap of the present invention has a solidification point of 44 to 55 ° C., wherein two or more soap bases colored in different colors are laminated, and the boundary of the lamination is in a state where the soap bases are mixed and blurred. It is what has become. Here, the “blurred state” of the boundary means a state in which the mixture of soap bases stays in the vicinity of the boundary and the boundary can be recognized but is not clearly recognized as a line. In the present invention, the “blurred state” may be formed on the entire boundary or may be partially formed. However, it is preferable that the “blurred state” is formed on the whole because the appearance is more beautiful.

  In the production of the multicolor laminated 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 mixture of soap base spreads not only in the vicinity of the boundary, but the boundary cannot be recognized. Conversely, if the freezing point of the soap base exceeds 55 ° C, the fluidity is low and it is easy to solidify, so it becomes difficult for the soap base to mix in the vicinity of the boundary, and the boundary becomes a line clearly. End up. Therefore, in both cases, it is not possible to produce a multicolor laminated soap in which the boundary is blurred 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, 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, and there is a risk that it is impossible to produce a multicolor laminated soap with blurred boundaries. is there.

  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 No. 205), Brilliant Fast Scarlet (Red No. 404), Permanent Red F5R (Red No. 405), Hansa Orange (Dai Dai No. 401), Hansa Yellow (Yellow No. 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 also 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 multi-color laminated frame kneaded soap of the present invention is manufactured by the following method by a frame kneading method using soap bases of two or more colors colored in different colors prepared as described above.

  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 the heat melting is not particularly limited, but is preferably a temperature 11 to 21 ° C. higher than the freezing point, and particularly 17 to 21 ° C. higher than the freezing point.

  The filled first soap base is then cooled to a temperature 7-2 ° C. below its freezing point, preferably 5-2 ° C. below its freezing point. If the cooling temperature is too low, even if the second soap base is filled thereon, it becomes difficult to mix in the vicinity of the boundary, and the boundary becomes a line and is clearly understood as a whole. On the other hand, if the cooling temperature is too high, the mixture spreads not only in the vicinity of the boundary, but the boundary cannot be recognized. Although the cooling method of the first soap base is not particularly limited, it can be controlled to a desired temperature and can be cooled relatively quickly, so that only the lower part of the first soap base is partially water-cooled and the rest is allowed to cool. Is preferred.

  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 the first soap base. Further, 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 from the viewpoint of workability, it is the same. Preferably there is. 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 lamination | stacking, but a 1st soap base: 2nd soap base is 1: 1-3, especially 1: 1-1 by weight ratio. 2 is preferred.

  The second soap base is filled into the cooled first soap base at a temperature 11 to 21 ° C. higher than its freezing point, in particular 17 to 21 ° C. higher than its freezing point. When the filling temperature of the second soap base is too low, it becomes difficult to mix in the vicinity of the boundary, and the boundary becomes a line and is clearly understood as a whole. On the other hand, if the filling temperature is too high, the mixture spreads not only in the vicinity of the boundary, but the boundary cannot be recognized. The filling temperature of the second soap base is 18 to 23 ° C. higher, preferably 16 to 23 ° C. higher than the cooling temperature of the first soap base. 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, the production of the two-color laminated frame kneaded soap in which the boundary is blurred using the first and second soap bases has been described, but the first, second and third soap bases are used to produce three colors. The above laminated frame kneaded soap can also be manufactured. That is, after filling the second soap base, it is cooled to the same temperature as that of the first soap base, and then the third soap base is cooled to the same temperature as that of the second soap base. Fill with. By repeating this process, a laminated frame kneaded soap of three or more colors can be produced. Here, the first soap base and the third soap base may be the same color.

  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, 3 parts of ethanol and 16.9 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 3, in the said prescription, 20 parts of glycerol and ethanol were changed into 0 parts, and the comparative example 4 changed the prescription into 2 parts of glycerol and 16 parts of ethanol.

  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).

  In Example 2, a white first and third soap base (33 g each) and a red second soap base (33 g) were used.
