Description

[Detailed description of the invention]

The present invention relates to a bath agent composition containing an aloe fraction subjected to a specific treatment. Traditionally, aloe vera and aloe extracts have been used, especially in folk medicine, to treat cracks, chaps, burns, cuts, athlete's foot, and the like. However, aloe extract has a unique odor, is dark brown in color, and contains anthraquinone derivatives such as aloin, which are easily discolored. etc. become a big problem. For this reason, the blending amount was also limited to a small amount, and the effect could not be fully exhibited. The purpose of this invention is to provide enough moisture and smoothness to dry skin due to cracks, rashes, roughness, etc. after bathing, without the odor peculiar to aloe extract, and with a storage-stable system. To provide a bath agent composition which has high properties and is free from problems such as coloring and discoloration. That is, the present invention provides a bath agent composition containing an aloe fraction obtained by treating aloe sap with activated carbon. This invention will be explained in detail below. The aloe fraction used in this invention can be obtained using the following raw materials and processing steps. Suitable examples of aloe that can be used as raw materials include aloe vera, syabone aloe, and kidachi aloe. The sap obtained by squeezing, crushing, crushing, etc. the whole plant, leaf or jelly part of aloe is preferably passed through these and subjected to the next activated carbon treatment. In addition, the sap mixed with solid matter may be passed on to the next process as it is. In that case, the solid matter is removed at an appropriate later stage. Next, the aloe sap thus obtained is treated with activated carbon by a batch method. This activated carbon treatment reliably removes colored components that are easily discolored, resulting in a colorless to pale yellow, water-soluble substance that has physiologically active effects for wound treatment and the like.
On the other hand, if activated carbon treatment is not performed,
Colored components and water-insoluble components are not removed well, and this is not suitable as a bath agent component of the present invention. The activated carbon used in this batch method activated carbon treatment may be animal charcoal, such as animal charcoal or bone charcoal, or vegetable charcoal, such as coconut shell charcoal, but vegetable charcoal, which has high adsorption power and is inexpensive, is more preferable. Activated carbon may be powdered or granular, but powder, especially 100%
~400 mesh is preferred. The amount of activated carbon to be used is preferably 0.1 to 20% (weight %, same hereinafter), more preferably 1 to 10%, based on the weight of the original aloe sap. When treating activated carbon by the batch method, it is preferable to stir the liquid by means such as mechanical stirring after adding the activated carbon, but in this case, the stirring time is preferably 15 minutes to 3 hours, particularly 30 minutes to 1 hour. . Yes, the activated carbon treatment can be carried out at low temperature or room temperature, and when carried out simultaneously with the heat treatment described below, it is carried out under heating. After activated carbon treatment, if other treatments are to be carried out after that, the activated carbon can be removed as is, preferably after the activated carbon has been removed, and then subjected to the prescribed treatment, or if activated carbon treatment is carried out as the final step, it can be separated as appropriate. Activated carbon is removed by a means, and the resulting liquid is collected as a target fraction. The target fraction obtained by the activated carbon treatment is almost colorless and transparent in the form of a treatment liquid. This target fraction has colored pigment components that easily change color and water-insoluble components removed, and has excellent physiologically active effects such as wound healing effects. Note that the treatment liquid can be added as it is to the bath additive composition of the present invention as a target fraction, but
Adopt an appropriate drying method such as heat drying, spray drying, freeze drying, etc. to distill off the moisture, and add the free white to pale yellow powder to a granular or powdered bath additive composition. It is more preferable to do so in terms of storage stability and the like. Furthermore, a more suitable aloe fraction can be obtained by carrying out a heat treatment in addition to the above activated carbon treatment. By this heat treatment, a physiologically active substance with excellent stability is obtained from which substances that are denatured by heating or aging (inflammatory substances) are removed. Furthermore, the heat treatment eliminates the viscosity of the aloe sap, making over-processing extremely easy, which is advantageous in terms of operability. Note that either the heat treatment or the activated carbon treatment may be performed first, or they may be performed at the same time.
It is preferable to perform the activated carbon treatment after the heat treatment, or to perform the heat treatment and the activated carbon treatment at the same time. The heat treatment is performed under normal pressure or reduced pressure,
The temperature is 50-90°C, more preferably 60-80°C.
Moreover, the heating time is 0.5 to 3 hours, more preferably 1 to 2 hours. If the heating temperature is lower than 50°C or the heating time is shorter than 30 minutes, the effect of the heat treatment will not be sufficiently exhibited, and the above impurity components will not be sufficiently removed in the process of separating insoluble materials. A situation may arise. Furthermore, if the heating temperature is higher than 90° C. or if the heating time is longer than 3 hours, problems such as deterioration and fermentation of the active ingredients and decomposition and solubilization of insoluble materials may occur. When performing the heat treatment, the aloe sap may be simply heated under the above treatment conditions, but
When performing this heat treatment, the aloe sap may be concentrated at the same time (in this case, it is desirable that the aloe sap be a concentrated liquid of 10 times or less, more preferably 2 to 5 times the initial amount of sap), or There is no problem even if it is almost completely evaporated. After the heat treatment, if this is done at the final stage, water-insoluble matter is removed by filtration or other means, and the target fraction is collected, and after the heat treatment, it is treated with activated carbon or treated with a water-soluble organic solvent as described below. When performing an extraction treatment, use it as it is or after removing water-insoluble matter. In addition, when performing activated carbon treatment after heat treatment, if the sap is concentrated during this heat treatment process, add water to this so that the concentrated liquid is preferably 2 to 10 times the initial amount of sap. It is preferable to add activated carbon. When obtaining the aloe fraction used in the present invention, in addition to the above-mentioned activated carbon treatment, or in addition to the activated carbon treatment and heat treatment, an extraction treatment with a water-soluble organic solvent can be performed. This allows resins and poorly soluble substances to be removed more reliably. This extraction treatment may be performed at any stage before or after the activated carbon treatment or heat treatment, but especially when performing the above three treatments, it may be performed before or after the activated carbon treatment after the heat treatment, Alternatively, it is preferable to perform an extraction treatment or before a step of simultaneously applying heat treatment and activated carbon treatment. In addition, when performing extraction treatment with a water-soluble organic solvent prior to activated carbon treatment or heat treatment,
Extraction is performed by adding an organic solvent to the aloe sap, and the extract is collected and the organic solvent is distilled off, or the organic solvent is distilled off and water is added to it for the next process (activated carbon treatment process, heating). processing process). When extraction treatment with a water-soluble organic solvent is performed after activated carbon treatment, extraction is performed by adding an organic solvent to the treated liquid obtained by removing activated carbon, preferably the concentrated liquid or dried product, and heat treatment. In the case of extraction after heating, an organic solvent is added to the sap after heat treatment, preferably its concentrated liquid or heat-dried product, and after extraction, the extract liquid,
The concentrated liquid or the one after the solvent has been distilled off is collected. In addition, when extraction treatment is performed as the final step, it is preferable to distill off the solvent from the obtained extract and collect it as the desired fraction, but depending on the purpose of use, distilling off the solvent may be necessary. Alternatively, the extract or its concentrate can be used as is (particularly when ethanol or isopropanol is used as the water-soluble solvent). In this extraction process, water-soluble solvents such as ethanol, methanol, isopropanol, n-propyl alcohol, n-butyl alcohol, tert-butyl alcohol, sorbitol, and acetone are used as organic solvents for extraction, and the extraction process is particularly performed using these solvents. It is preferable to use a mixed solvent with water containing a water-soluble solvent in a concentration of 20 to 80%, more preferably 25 to 40%. In this case, the water-soluble solvent may be used alone or in combination of two or more. In addition, the amount of organic solvent (water-soluble solvent, especially mixed solvent of water-soluble solvent and water) used should be 0.1
It is preferred that the amount is such that the concentration is ~30%, more preferably 1-10%. The extraction conditions are:
Conditions of a temperature of 0 to 25° C. and an extraction time of 1 hour to several days, more preferably 3 to 48 hours are preferably employed.
After the extraction process, the extract is collected. The target fraction obtained by performing this extraction treatment with a water-soluble organic solvent is one in which resins and poorly alcohol-soluble substances are reliably removed. Therefore, the target fraction obtained by the above method has an excellent tissue activating effect, does not contain colored pigment components that easily change color, and does not contain water-insoluble components, and is colorless to pale yellow. Heat-treated products reliably remove water-insoluble components (flame-causing substances) due to heat denaturation and denaturation over time, are stable, do not discolor or change in quality, and are easily extracted with water-soluble organic solvents. The treated products do not contain substances that are poorly soluble in alcohol, so even if they are blended into various products, their appearance etc. will not be impaired, and there is no risk of problems with the quality of the products. In addition, this physiologically active substance is water-soluble and dissolves in water at almost any ratio, that is, it has sufficient dispersibility in the bath and provides the moisturizing effect that the bath agent of the present invention has on the skin. Guarantees smoothness. Furthermore, this fraction is highly safe and does not cause irritation when applied to the skin. The bath agent composition of the present invention may use the above-mentioned aloe fraction alone, but may also contain the commonly used ingredients described below. In the case of bath preparations containing commonly used ingredients as described below, the amount of the aloe fraction in the total composition is usually 0.1 to 99%, preferably 0.1 to 95% by weight, and more preferably 0.1 to 30% by weight. . The bath composition of the present invention is usually used in an amount such that the aloe fraction has a concentration in the bath of 0.1 to 30 ppm. If the amount used is less than 0.1 ppm, the effect of moisturizing and smoothing dry skin will be insufficient. At 0.1ppm to 30ppm, an improvement in moist and smooth skin after bathing was observed.
When the concentration exceeded 30 ppm, almost no improvement in performance was observed, and a slight odor peculiar to aloe was observed. The bath agent which is an embodiment of the bath agent composition of the present invention and further contains commonly used ingredients in addition to the aloe fraction described above contains one or more of the following components in an amount of 1 to 99.9%, preferably 5 to 99.9%.
