Description

  The present invention relates to a cosmetic granulation composition and a method for producing the cosmetic granulation composition.

  In general, there are granulated compositions used for various purposes, but the granulated compositions used for cosmetics are required to have various physical properties unlike other granulated compositions. For example, in the case of a powdery facial cleanser, if the particle size is too small, it has a certain size because there is a disadvantage such as powdering and sucking, spilling around, or moisture absorption and hardening. What was granulated in the lump shape is preferable. However, when the granulated product has a too large particle size or the granulated product is too hard, it is not preferred by the user due to disadvantages such as pain in the palm during use and poor melting and poor foaming. On the other hand, if the strength of the granulated material is weak, the granulated material collapses due to pressure or shaking due to the weight of the granulated material itself during the production, transportation, or use. Disadvantages such as fine powder.

  Therefore, it is necessary for the granulating composition for cosmetics to be finished to a substantially constant size and to have an appropriate strength. For example, in the case of a facial cleanser, it is required to disintegrate by using a palm or water to wet it with a palm or extending it with fingers or palm, and to withstand high humidity conditions such as in the bathroom. It is also required to have physical properties such as being able to be used by being dispersed in a scrub agent as a part, and further in an aqueous / oily cosmetic base. And, with such physical properties, it can be used to increase the added value of cosmetics by characteristically blending the active ingredients, pigments, powders, and fragrances that are blended into cosmetics. is there.

  To obtain such a granulation composition for cosmetics, select a base that has safety and stability that can be blended into cosmetics, and that can have both moderate strength and disintegration, and further blend components that increase added value It is manufactured through a process such as granulation, finishing to a preferred particle size and drying, but in order to maintain a balance between strength and disintegration, the size of the granulation composition For example, in the case of almost spherical particles, when the diameter exceeds about 0.7 mm, the balance between strength and disintegration is lost, and when the strength is satisfied, moderate disintegration cannot be obtained. On the other hand, if the diameter is less than about 0.2 mm, the appearance is just a fine powder category, and the meaning of granulation is lost.

  Conventionally, in order to produce a granulated product having such a disintegrating property, a powdery base is usually used, and after a certain amount of water is added and mixed uniformly, the mixture is further mixed vigorously. A method of granulating (mixing method), a method of spray-drying a material with increased fluidity by adding slightly larger water (fluidization method), and water was added to a plate with a large number of holes of a certain size A method such as a method of extruding by applying pressure in the state (extrusion method) is employed. And granulating by these methods, drying, and also granulating the granulated material or aligning the size and shape by methods such as taking corners are performed.

  However, it is difficult to make the size of the granulated material uniform by the mixing method, and even if the granulation is insufficient, fine powder is mixed even if it is granulated excessively and then broken into finer particles. There is a problem of doing. On the other hand, the flow method is preferable in terms of particle uniformity, disintegration, solubility, and the like, and further contains air bubbles inside during drying, so that the particles become lighter and the most preferable finish in terms of lightness. Is obtained. However, in the flow method, hot air from below is blown up to evaporate a relatively large amount of water, so that there are drawbacks such as increased capital investment and very high energy costs.

  On the other hand, in the conventional extrusion method, the diameter at the time of extrusion is 0.5 mm as the lower limit, and the diameter of the granulated product obtained by extrusion with a diameter exceeding 0.5 mm is too large, so that it is folded to the required short. In addition, not only the diameter but also the length was too long, which was unsuitable for a granulated product of cosmetics.

  By the way, as an invention related to a conventional granulation composition for cosmetics, for example, a patent application such as the following Patent Document 1 has been filed. It is disclosed that the cosmetic granulation composition disclosed in Patent Document 1 can also be produced by the mixing method, flow method, extrusion method and the like as described above. It is disclosed that the flow method is preferable for reasons such as being suitable for (Patent Document 1 [0007]). However, the above-mentioned problems with the flow method, such as increased capital investment and energy costs, cannot be ignored, and a solution is desired.

JP 2003-277216 A

The present invention has been made in order to solve the conventional problems as described above, and an object of the present invention is to provide a granulated composition having preferable physical properties for cosmetics as described above.

  In view of the problems of the flow method as described above, the present inventors focused on the point of adopting an extrusion method generally accepted as unsuitable for cosmetics, and as a result of earnest research, the inventors have found that a prescribed range of prescription and construction Extrusion granulation can be performed with a caliber of 0.3 to 0.5 mm, which has been considered difficult in the past, with the moisture content at the time of granulation. The inventors have found that a granulated composition having preferable physical properties can be produced, and have completed the present invention.

  That is, the invention according to claim 1 relating to a cosmetic granulation composition is a granulation composition which is extruded and granulated by extrusion granulation and dried by a diameter of 0.3 to 0.5 mm. It is characterized by blending 40 to 80% by weight of talc and 5 to 20% of crystalline cellulose or cellulose derivative. The invention according to claim 2 is characterized in that in the granulation composition for cosmetics according to claim 1, the granulation composition is a granular face wash.

  Furthermore, the invention according to claim 3 relating to the method for producing a granulation composition for cosmetics is a granulation which is extruded and granulated and produced by extrusion granulation method with a diameter of 0.3 to 0.5 mm. It is a manufacturing method of a composition, Comprising: It mix | blends and manufactures talc 40-80 weight%, crystalline cellulose, or a cellulose derivative 5-20%, It is characterized by the above-mentioned. The invention as claimed in claim 4 is characterized in that, in the method for producing a granulating composition for cosmetics according to claim 3, 5 to 25% by weight of water is contained with respect to the total amount of the composition during extrusion granulation. .

  In the present invention, by blending 40 to 80% by weight of talc and 5 to 20% of crystalline cellulose or cellulose derivative as described above, 0.3 to 0 smaller than the diameter adopted in the general extrusion granulation method. It is possible to produce a granulated product by extrusion with a diameter of 5 mm, and as a result, the granulated composition thus obtained is not too large in diameter and too long in length. It can be suitably used as a granulated product for cosmetics.

  Furthermore, it is possible to provide a granulating composition for cosmetics that is excellent not only in terms of size but also in terms of physical properties. For example, when the granulating composition for cosmetics of the present invention is used as a granular facial cleanser, it does not contain any fine powder, so there is no powdering, and especially when the palm is melted by adding an appropriate amount of water to the palm during use. There are advantages such as no pain, moderate disintegration, easy melting and good foaming.

  In addition, since it is possible to employ an extrusion granulation method, the cost required for capital investment, energy cost, etc., compared with those obtained by the flow method that has been widely employed in the production of conventional granulation compositions for cosmetics. Can be greatly reduced.

  As described above, the granulation composition for cosmetics of the present invention is a granulated product that is extruded and granulated by drying with an extrusion granulation method of 0.3 to 0.5 mm, and dried. It contains 40 to 80% by weight of talc and 5 to 20% by weight of crystalline cellulose or cellulose derivative.

Here, it was decided to extrude with a diameter of 0.3 to 0.5 mm because the granulated product extruded with a diameter exceeding 0.5 mm cannot be folded to the required short because the diameter is too large. This is because the length is too long and is not suitable for cosmetic granulation. Also, when the aperture is less than 0.3 mm, the strength of the granulated product is insufficient, and the granulated product itself is granulated with great pressure by shaking or mixing during the production, transportation or use. This is because things may become fine powder.

  Moreover, the blending amount of talc is set to 40 to 80% by weight. When the amount is less than 40% by weight, there is a problem that viscosity is generated at the stage of granulation and the physical properties are not suitable for extrusion granulation. If the content exceeds 50%, the granulated material becomes brittle and easily collapses.

Further, the blending amount of crystalline cellulose or cellulose derivative was 5 to 20% by weight.
If the amount is less than 5% by weight, moisture absorption resistance cannot be sufficiently obtained, so that there is a problem that the granules adhere to each other due to long-term storage or use in the bathroom. This is because the amount of water necessary for granulation increases, and there is a problem that it takes more time than necessary for drying after granulation. Examples of the cellulose derivative include methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose and the like.

  Moreover, in the manufacturing method of the granulation composition for cosmetics of this invention, it is also possible to contain 5-25 weight% of water | moisture content with respect to the composition whole quantity at the time of extrusion granulation. In this case, the amount of water to be contained is 5 to 25% by weight. When the amount is less than 5% by weight, there is a problem that a granulated product cannot be obtained at the stage of granulation, but it exceeds 25% by weight. This is because there is a problem that the granulated materials obtained at the granulation stage adhere to each other.

  Although the use of the granulating composition for cosmetics of this invention is not ask | required, it can be used, for example as a granular face wash.

  The granulated composition of the present invention is a detergent, surfactant, moisturizer, thickener, preservative, emulsifier, medicinal component, oily component, ultraviolet absorber, dye, which is generally used as a cosmetic ingredient. It can be blended into cosmetics together with flavors, emulsion stabilizers, proteolytic enzymes and the like. In particular, when used as a granular facial cleanser, it is essential to include a cleaning component. In this case, the cleaning component includes fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, isostearic acid, or the like. Fatty acid salts such as sodium salt, potassium salt, triethanolamine salt, sodium N-lauroyl-L-glutamate, sodium N-myristoyl-L-glutamate, sodium N-stearoyl-L-glutamate, N-coconut oil fatty acid acyl-L -Sodium glutamate, N-coconut oil fatty acid acyl-L-glutamic acid potassium, N-coconut oil acylglycine potassium, N-coconut oil fatty acid acylglycine sodium, N-coconut oil fatty acid acyl-L-glutamic acid triethanolamine, N-lauroyl -L-glutamine Triethanolamine, N-coconut oil fatty acid acylmethyl taurine sodium, N-myristoyl methyl taurine sodium, N-stearoyl methyl taurine sodium, lauroyl sarcosine sodium, lauroyl sarcosine potassium, myristoyl sarcosine sodium, palmitoyl sarcosine sodium, lauroyl methyl alanine sodium, etc. Anionic detergents such as amino acid-based anionic detergents, sodium lauryl phosphate, sodium lauryl ether phosphate, sodium (12-15) alkyl ether sulfate, sodium lauryl sulfosuccinate, sodium lauryl glycol acetate, lauryl dimethylaminoacetic acid betaine, Coconut oil fatty acid amidopropyldimethylaminoacetic acid betaine, N-coconut oil fatty acid acyl-N In addition to amphoteric detergents such as sodium carboxymethyl-N-hydroxyethylethylenediamine, nonionic detergents such as lauryl diethanolamide, coconut oil fatty acid dietanolamide, stearic acid dimethylaminopropylamide, etc. can be mentioned, There is no restriction | limiting in particular in a mixing | blending. Furthermore, the amount of the cleaning component typified by these is a condition that it does not affect the production stage and the quality of the resulting granulated product, but is usually about 10 to 40% by weight. preferable.

  Examples of the present invention will be described below.

  Thereafter, a scale of 30 kg in total with components other than water (the above percentage display × 300 times (g)) was processed in the same manner as in Example 1 to obtain 28.7 kg of a granular facial cleanser.

(Example 3)
In this example, the cosmetic granulation composition of the present invention is applied to a yellow scrub agent. The prescription of the granulating composition for cosmetics of this example is as follows.

Composition Blending amount (% by weight)
(A) Powder component Talc 78.6%
Crystalline cellulose 12.0%
Hydroxyethyl cellulose 3.0%
Hydroxypropyl cellulose 3.0%
Stearoyl L-sodium glutamate 3.0%
Dipotassium glycyrrhizinate 0.2%
Gardenia yellow pigment 0.2%
(B) Liquid component water 15.0%
(A total of 100.0% for components other than water and 15.0% for water)

  Similar to Example 1 except that a dedicated dome with a diameter of 0.45 mm was used instead of a dedicated dome with a diameter of 0.3 mm on a scale (percentage display x 300 times (g) above) with a component other than water of 30 kg. It processed and obtained 29 kg of yellow scrub agents for mix | blending with a powdery face wash.

(Comparative Example 1) Facial cleanser comprising a mixture of powder and granule by mixed granulation method The same formulation as in Example 1 except that water in component B in Example 1 was not used, and a total amount of 30 kg with components other than water. After weighing each component on the scale (percentage display x 300 times (g)), the component A (powder component) was charged into the 100-L capacity mixing kettle used in Example 1 and only the powder component was added. Mixed to be uniform.

  Next, while mixing the A component, the B component (liquid component) was added to make the whole uniform, and then the mixing was continued to obtain a granulated product having a main product diameter of 2 to 5 mm. The obtained granulated product is dried using a fluid dryer, and then pulverized using a slit (metal mesh) having a sieve size of 0.8 mm to obtain 29.3 kg of a facial cleanser comprising a mixture of powder and granules. Obtained.

  The face wash thus obtained was continuously passed through a sieve having sieve openings of 1.0 mm, 0.6 mm, 0.3 mm, and 0.1 mm, respectively, and obtained according to the size of the particles. When the particle size distribution was examined based on the weight percentage of the category, the following results were obtained.

1.0mm or more 0.2wt%
0.6-1.0mm 7.9wt%
0.3-0.6mm 42.4% by weight
0.1-0.3mm 38.5% by weight
0.1mm or less 11.0% by weight

(Comparative Example 2) Granular face wash by extrusion granulation method, diameter 0.7 mm
The same operation as in Example 1 was performed except that a dedicated dome with a diameter of 0.7 mm was used instead of the dedicated dome with a diameter of 0.3 mm in Example 1. As a result, 29.7 kg of a granular facial cleanser was obtained.

(Summary)
Each of the granular face wash prepared in Examples 1 and 2 has almost a predetermined particle size (diameter 0.3 mm) and a length of 3 to 5 mm, and contains substantially no fine powder. Moreover, when it was used, it was taken in the palm of the hand and melted by adding an appropriate amount of water or hot water.

  The yellow scrub agent prepared in Example 3 has a predetermined particle size (diameter 0.3 mm) and a length of 3 to 5 mm, and contains substantially no fine powder. This was prepared in Example 1 or 2. By adding 2% by weight to the granular facial cleanser, a granular facial cleanser with a yellow scrub was obtained, but it was beautiful as a cosmetic product, and there was no pain in the palm, especially during use. It was confirmed that the scrubbing agent was left as a scrubbing agent, but soon collapsed and disappeared.

  On the other hand, in Comparative Example 1, among the sections divided in particle size as described above, those in the range of 1.0 mm or more and 0.6 to 1.0 mm are not powdered, but when used as a face washing powder, Disadvantages such as pain in the palm, difficulty in melting, and slow foaming were clearly observed. Even in the range of 0.3 to 0.6 mm, the palm hurts and a tendency to hardly melt was recognized. On the other hand, when taking out the container of 0.1 mm or less, there is a risk that if the contents are spilled, fine powder will be formed (fine powder will fly in the air), and it may be sucked in. Furthermore, bathing in the bathroom When used for the above, there were obvious defects such as quick moisture absorption, the contents were not exposed, and the contents were not easily produced even when the container was tilted. That is, the face wash made of a mixture of the powder and particles obtained in Comparative Example 1 has a defect due to the particle size distribution.

  Furthermore, when the granular face wash obtained as in Comparative Example 2 was used, defects such as pain in the palm, difficulty in melting, and slow foaming were clearly observed.

  From the above, it was found that the granular face wash of Examples 1 and 2 were superior in physical properties to those of Comparative Examples 1 and 2.
