  However, in the process of manufacturing a cosmetic by adding a shirasu foaming agent as an additive to the cosmetic composition, the viscosity of the cosmetic composition may increase due to the water absorption of the shirasu foaming agent and productivity may decrease. However, in the conventional cosmetic production method, water absorption of the shirasu foaming agent is not sufficiently considered, and therefore, when a shirasu foaming agent having a high water absorption rate is added to the cosmetic composition, the cosmetic composition As the viscosity of the liquid becomes high, it becomes difficult to fill the container such as a tube and the productivity is lowered as described above. Furthermore, even after the production of the cosmetic composition, the components may begin to separate in a relatively short period of time, and there is a problem that the storage stability of the cosmetic composition is reduced.

  Since the present invention has been made in view of such problems, the object is not to increase the viscosity of the composition at the time of manufacture, to ensure long-term storage stability and good productivity, Another object of the present invention is to provide a cleaning composition containing a shirasu balloon that does not cause the skin surface to be damaged and a method for producing the same.

  In order to achieve the above object, the cleaning composition of the present invention, as described in claim 1, is a creamy cleaning composition mainly composed of fatty acid soap, and has a particle size of 75 μm or less. And 6-10 weight% of Shirasu balloon whose water absorption is 70% or less is added, It is characterized by the above-mentioned.

  In the cleaning composition thus configured, the invention according to claim 2 is characterized in that the particle size of the shirasu balloon added to the composition is 20 μm to 45 μm.

  The invention according to claim 3 is a method for producing the cleaning composition, wherein the particle size of the shirasu balloon obtained by firing and foaming after adjusting the structure water of the shirasu rough to 3 to 6% is 20 μm to It is characterized by being classified and selected so as to have a thickness of 75 μm, and this shirasu balloon is added to and mixed with the ingredients of the cleaning cosmetic.

  According to the cleaning composition of the present invention, as described in claim 1, the cleaning cosmetic component mainly composed of a fatty acid soap has a particle size of 75 μm or less and a water absorption of 70%. Since 6 to 10% by weight of the following shirasu balloon is added, the viscosity at the time of production of the cleaning composition is difficult to increase, the storage stability is improved, and there is no risk of damaging the skin at the time of use. In addition, it is possible to obtain a cleaning composition that is also effective and has a high cleaning effect.

  Furthermore, according to the invention according to claim 2, since a fine classified product having a particle size of 20 to 45 μm is used as a shirasu balloon to be added to the cleaning cosmetic component, a shirasu having a particle size larger than 45 μm. Since the balloon is removed, the composition has a smooth property and excellent usability. In addition, many large shirasu balloons having a particle diameter of 20 μm or less are immaturely foamed, and the shape of the balloon However, since such a shirasu balloon is removed, a cleaning composition that hardly damages the skin surface can be provided.

  Further, according to the method for producing a cleaning composition of the present invention, first, a shirasu balloon obtained by firing and foaming after adjusting the structure water of the shirasu rough to 3 to 6% has a particle size of 20 μm to 75 μm, preferably 20 μm. Shirasu balloons having a particle size of 20 μm to 75 μm, preferably 20 μm to 45 μm and a water absorption of 70% or less can be obtained with high productivity. Since Shirasu Balloon is added to and mixed with the components of the cleaning cosmetics, it can be mixed and mixed with the components of the cleaning cosmetics with good dispersibility, and the viscosity of the resulting cleaning composition is extremely low because of its low water absorption. Therefore, not only the productivity is improved, but also there is an advantage that the mechanical load of the filling device can be reduced because the viscosity does not increase when filling a tube or the like. . In addition, it is possible to obtain a cleaning composition having high storage stability and a high cleaning effect, which hardly damages the skin surface with high productivity.

  When a specific embodiment of the present invention is described in detail, a fatty acid soap is used as a main component of a cleaning cosmetic, and a cleaning composition is obtained by adding a shirasu balloon to the cleaning cosmetic component. As a shirasu balloon, a shirasu balloon obtained by baking and foaming a shirasu which is a volcanic ejecta (volcanic ash ore) at about 700 to 1000 ° C. for several seconds is used. In this case, a shirasu balloon having a particle size of about several μm to 100 μm is obtained, although it depends on the shirasu firing conditions. In addition, when baked at 1000 degreeC or more, the expansion ratio of a shirasu balloon will become large and a thing below 70 micrometers will decrease, and productivity is not good.

  When the shirasu is fired, the structural water of the shirasu is adjusted in advance, so that the expansion ratio and the foamed shape are stabilized, so that a shirasu balloon having a stable water absorption rate can be obtained with high productivity. In particular, when the structural water is adjusted to 3 to 6%, a shirasu balloon having a particle size of 75 μm or less can obtain a water absorption of 70% or less.

  The particle size of the shirasu balloon added to the cleaning cosmetic component is preferably 75 μm or less. When the particle size of the shirasu balloon exceeds 75 μm, when using the cleaning composition to which the shirasu balloon is added, it is easy to cause roughness to the bare skin, and the feeling of use is lowered. It becomes easy to have a pinhole and a shirasu balloon with a high water absorption rate increases. When a cleaning composition is produced using a shirasu balloon having a high water absorption rate such that the water absorption rate exceeds 70%, the viscosity of the resulting cleaning composition increases and storage stability decreases.

  Accordingly, it is preferable to use a shirasu balloon that is classified and classified to a particle size of 75 μm or less, particularly 20 to 45 μm, as the particle size of the shirasu balloon. As described above, the uniform particle size of the shirasu balloon makes it easy to knead and disperse the components of the cleaning cosmetic during the production of the cleaning composition, so that the components of the ancestry are likely to be uniform. Shirasu balloons having a particle size of less than 20 μm are preferable because the surface is often jagged and angular and rough, and the foamed state is often unfavorable, which increases the risk of finely damaging the skin surface during use. Absent.

  On the other hand, shirasu balloons with a particle size larger than 45 μm are likely to break up or have fine pinholes or slits on the surface, and many are not good in the foamed state. This tends to reduce the productivity and storage stability of the cleaning composition. In addition, various methods, such as air classifications, such as a vibration sieve and a micron separator, can be employ | adopted for the classification selection method of a shirasu balloon.

  Furthermore, the additive for the shirasu balloon to be added to the cleaning cosmetic component in the cleaning composition is required to be 6 to 10% by weight. If the additive amount of the shirasu balloon is less than 6% by weight, it is difficult to obtain a high cleaning effect due to the addition, that is, exerting the dirt adsorption performance of the shirasu balloon. A lot of cleaning cosmetic ingredients are likely to enter the inside of the shirasu balloon, the viscosity of the mixed components for obtaining the cleaning composition increases, making it difficult to manufacture, and adding more moisture than necessary. Therefore, the productivity is lowered, and even after the cleaning composition is obtained, the moisture inside the shirasu balloon is easily released due to the change with time, and the storage stability is lowered. Moreover, the foam holding power which is the characteristic of soap will fall, and a usability | use_condition will be impaired. And in order to achieve 6-10 weight% which is the addition amount with good productivity, maintaining such high detergency and usability, it will become difficult when a water absorption exceeds 70%. Therefore, the water absorption needs to be 70% or less, preferably 64% or less.

  The cleaning composition of the present invention is a soap whose main component is fatty acid sodium or fatty acid potassium, and is a creamy facial cosmetic, finger cosmetic, body soap, or the like. As creamy soap base, fatty acid potassium soap is usually used, but in the case of cream, fatty acid base amino acid soaps such as fatty acid sodium soap and fatty acid arginine soap can be used, and if necessary, Ingredients used in normal cosmetics can be arbitrarily added to the main component to make cosmetic ingredients. For example, nonionic surfactants such as sucrose fatty acid esters, anionic surfactants such as higher fatty acid salts, amphoteric surfactants such as carboxybetaine, fatty acids such as oleic acid and stearic acid, and higher grades such as oleyl alcohol and cetanol Alcohols, triglycerides such as olive oil and beef tallow, hydrocarbons such as petrolatum and squalane, esters such as gallow and jojoba oil, humectants such as glycerin, thickeners such as ethanol, preservatives, antioxidants, ultraviolet rays Add ingredients such as absorbents, pigments, and fragrances.

  The shirasu obtained by the above manufacturing method in the component (raw material) of the cleaning cosmetic comprising the fatty acid soap as a main component and, if necessary, components such as the surfactant and humectant added. A cream-like (semi-solid or liquid) cleaning composition is obtained by adding a balloon and mixing and kneading. In order to obtain the fatty acid soap, a general production method such as saponification or neutralization may be used. For example, stearic acid, palmitic acid, myristic acid, cetanol, lanolin, glycerin and preservatives are mixed in an appropriate amount and heated to 80-90 ° C. as an oil phase. Separately, potassium hydroxide, shirasu balloon, and purified water are used. A cleaning composition can be formed by mixing an appropriate amount and heating to 80 to 90 ° C. to form an aqueous phase, adding the aqueous phase to the oil phase, stirring and mixing, and slowly cooling.
