Description

  The present invention relates to a cleaning material, more specifically, a so-called cleansing foam mainly composed of higher fatty acids.

  Cleansing foam consists of higher fatty acids and water, some of which are neutralized with alkali. Essentially, polyhydric alcohols are added to supplement moisture retention, and oil components such as jojoba oil and liquid paraffin are used. Is a preparation formulated.

  Cleansing foam is inferior in stability. For example, if it is left at a high temperature of about 40 ° C, such as in a car in the summer, liquid will ooze out from the cleansing foam, and moisture will be separated if left in a higher temperature environment. As a result, the value of the product was decreasing. For this reason, storage in an environment of 35 ° C., preferably 30 ° C. or less, has been unavoidable.

  In order to improve the stability of the cleansing foam, for example, JP-A-60-92399 (Patent Document 1) discloses the incorporation of a water-soluble polymer and / or a water-swellable clay mineral.

Japanese Patent Application Laid-Open No. 2002-226359 (Patent Document 2) discloses a predetermined amount of stearic acid and myristic acid, a predetermined amount of alkali that neutralizes these fatty acids, glycerin and / or polyglycerin in an amount of 20 to 50 wt. % Cleansing foam is disclosed.
JP-A-60-92399 JP 2002-226359 A

  However, for example, when 20% or more of polyhydric alcohol such as polyglycerin is used, foaming is lowered and the cleaning effect may be lowered. Therefore, in order to maintain the detergency, the blending amount of these polyhydric alcohols may be less than 20%. In this case, the water-soluble polymer as disclosed in Patent Document 1 is sufficiently stable. There was a case that sex could not be secured.

  The present invention has been made in view of the above-described background art, and an object of the present invention is to provide a cleansing foam excellent in stability, particularly a cleansing foam having a low blending amount of polyhydric alcohol and good foaming.

  The cleaning material of the present invention is a cleaning material mainly composed of a higher fatty acid partially neutralized with an alkali, and is characterized by containing an extract of white jellyfish.

  According to the present invention, a cleaning material having improved stability at high temperatures is provided, and the storage conditions of the cleansing foam are eased.

  The cleaning material of the present invention is a cleaning material mainly composed of a higher fatty acid partially neutralized with an alkali, and contains an extract of white jellyfish as a so-called stabilizer.

  The higher fatty acid used in the present invention is a fatty acid having 8 to 22 carbon atoms, which may be a linear fatty acid or a branched fatty acid, and may be any saturated or unsaturated higher fatty acid. Good. Specific examples include lauric acid, palmitic acid, stearic acid, behenic acid, palmitooleic acid, oleic acid, isomyristic acid, isopalmitic acid, isostearic acid and the like. In the present invention, one or more of these higher fatty acids are used.

  The amount of higher fatty acid used in the present invention is at least 20% by mass in the detergent composition. If it is 20 mass% or less, it does not foam and does not exhibit the effect as a cleaning material. Moreover, the cleansing foam is preferably blended at a high concentration of 30% by mass or more. Although the upper limit of a compounding quantity is not specifically limited, Usually, it is 60 mass% or less in a composition.

  Examples of alkalis that neutralize fatty acids include inorganic alkalis such as sodium hydroxide and potassium hydroxide, and organic alkalis such as N-acylamine. From the viewpoint of stability, inorganic alkalis such as sodium hydroxide and potassium hydroxide are used. Preferably used.

  Higher fatty acids are partially neutralized by these alkalis. The neutralization amount is 20 to 80%, preferably 30 to 60% of the higher fatty acid as an equivalent. If it is less than 20%, the function as a soap will not be exhibited, and if it exceeds 80% it will be hardened like a solid soap and the appropriate foamy soap will not be obtained if neutralized. There is.

  In addition, in the manufacturing process of detergents, it is common to neutralize fatty acids by mixing fatty acids and alkalis, but instead of neutralizing with higher fatty acids and alkalis, some of them were previously neutralized with alkalis. Higher fatty acid salts may be used. As this higher fatty acid salt, the sodium salt and potassium salt of each said fatty acid are illustrated. Further, sodium salts and potassium salts of mixed higher fatty acids such as coconut oil fatty acid salts derived from natural products can also be used.

  In the present invention, a liquid oil component at room temperature is blended as necessary. Examples of oils that can be used include hydrocarbons such as liquid paraffin and squalane, octyldodecyl myristate, isononyl isononanoate, isopropyl myristate and the like, glyceryl trioctanoate, triglycerides such as tri (caprylic and capric acid) glyceryl, Examples include vegetable oils such as olive oil, jojoba oil, evening primrose oil, coconut oil, silicones such as dimethylpolysiloxane, methylphenylpolysiloxane, and cyclic methylpolysiloxane, higher alcohols such as octyldodecanol, and the like. Or 2 or more types are used. The blending amount of these oil components is 0.01 to 2% by mass, preferably 0.05 to 1% by mass in the cleaning material.

  Moreover, a humectant is mix | blended as needed. Examples of the humectant used include polyhydric alcohols such as glycerin, polyethylene glycol, propylene glycol, dipropylene glycol, and 1,3-butylene glycol, and sugar alcohols such as sorbitol and maltitol. Two or more are used. The blending amount of these humectants is 1 to 30% by mass, preferably 2 to 20% by mass in the cleaning material.

  Furthermore, the extract of the white jellyfish which is an essential component as a stabilizer is blended in the cleaning material of the present invention. The white jellyfish used in the present invention is a generic name for mushrooms belonging to the family Asteraceae, and in the present invention, it is not limited to the white jellyfish (Sterrel jellyfish) (scientific name: Tremella fuciformis B.), and (Tremella mesenterica Retz. Fr.) and the like are used. The white jellyfish can use mycelia as well as fruit bodies.

  Extraction solvents include water, lower alcohols having 1 to 4 carbon atoms such as methanol and ethanol, polyhydric alcohols such as 1,3-butylene glycol and propylene glycol, hydrocarbons such as hexane and pentane, and ketones such as acetone and methyl ethyl ketone. And ketones such as ethyl ether, propyl ether and tetrahydrofuran, acetonitrile and the like. These solvents may be used alone or in combination of two or more. Among these, it is preferable to use water or a mixed solution of water or a solvent that can be mixed with water at an arbitrary ratio, for example, ethanol or 1,3-butylene glycol.

  The extraction method is not particularly limited, and for example, a method of removing the bacterial cells after mixing the extraction solvent and the bacterial cells and performing warm extraction is exemplified. The obtained extract can be used as it is, or can be appropriately concentrated, or dried in a powder form by spray drying or freeze drying. If necessary, it is possible to remove impurities by decolorization with activated carbon or liquid-liquid extraction. For example, a white jellyfish polysaccharide obtained by purification is exemplified. As this polysaccharide, a commercially available white jellyfish polysaccharide (for example, “Blancveil-TP” manufactured by Nippon Seika Co., Ltd.) may be used.

  The obtained white jellyfish extract is preferably used in the cleaning material in an amount of 0.01% by mass to 1.0% by mass, and desirably 0.05% by mass to 0.5% by mass. If the amount used is large, the stability is increased, but the effect commensurate with the blending amount may not be obtained, and depending on the formulation, the cleaning agent may become hard and the feeling of use may be reduced.

  The cleaning material of the present invention is produced by a conventional method. As an example, essential components such as alkali, water, white jellyfish extract and optional polyhydric alcohol are heated and dissolved in an aqueous phase. Is added under warming to neutralize the fatty acids. Further, if necessary, a surfactant, a fragrance, a coloring agent, a preservative, and the like may be further added as optional components within a range not impairing the object of the present invention.

  In the present invention, potassium chloride can be optionally added in addition to the above components. As a result, the preparation is excellent in usability and does not become too soft even in a high temperature environment, and does not become too hard even in a low temperature environment. The blending amount is preferably 0.1 to 0.5% by mass. If the amount is less than 0.1% by mass, the effect of adding potassium chloride may not be seen. If the amount of potassium chloride exceeds 0.5% by mass, a salting-out effect is imparted and the fatty acid may be separated. Because there is.

  Next, the present invention will be further described with reference to examples.

  Various cleansing foams were prepared based on the component tables shown in Tables 1 and 2. The manufacturing method is as follows. A part of purified water and components 1 to 16 are dissolved by heating and stirring, and kept at 75 ° C. as an oil phase. Ingredients 17 to 20 and the remaining purified water are dissolved and kept at 75 ° C. to form an aqueous phase. Add the water phase to the oil phase, mix and stir until uniform, and cool to 35 ° C. with stirring. Thereafter, the laminate tube was filled to obtain various cleaning materials. In addition, Alkathylan in the table is a polysaccharide (Alcaligenes Polysaccharides) produced by Alcaligenes lathus, which is commercially available under the trade name "Alkathylan" (manufactured by Hakuto Co., Ltd.), The white jellyfish extract is commercially available under the trade name “Blancveil-TP” (manufactured by Nippon Seika Co., Ltd.).

  Next, after this cleansing foam is filled into a laminate tube, in order to evaluate the usability under each temperature environment, it is left to stand in each temperature environment of 5 ° C., 25 ° C. and 40 ° C. for half a day. The state of was evaluated. Moreover, in order to evaluate the stability under high temperature, it evaluated after that about the state of a formulation. Moreover, it preserve | saved for 60 days under the temperature of 38 degreeC and 50 degreeC, and investigated the stability. The results are shown in Tables 1 and 2. The evaluation criteria are as follows.

<Evaluation criteria>
(Preparation state)
◎: Easily removed from the tube and no separation was observed. ○: Slightly hard or somewhat soft, but can be removed from the tube without problems. X: Too hard to get out of the tube, or too soft to flow out of the tube. XX: Separation Can not hold creamy dosage form (stability)
○: Separation was not observed and stable ×: Separation was observed and unstable

  As shown in Tables 1 and 2, it was confirmed that the use of a white jellyfish extract increases the stability. In addition, it was confirmed that if potassium chloride was added, it could be used as a good product even under a low temperature of about 5 ° C. or a high temperature environment of about 40 ° C. On the other hand, by using a white jellyfish extract even if the blend is unstable when a water-soluble polymer such as hydroxyethyl cellulose or carboxyvinyl polymer is used as a stabilizer such that the polyhydric alcohol is less than 20%. It was confirmed that the stability of the cleansing foam could be improved. As for Comparative Example 11, when the amount of the white jellyfish extract is 0.6%, good high-temperature stability is obtained, but the state of the preparation becomes hard, and the state of the preparation is not improved by adding potassium chloride. It is a thing.

  In addition, when a white jellyfish extract is not blended, and when sodium chloride or sea salt (a mixture of sodium chloride, potassium chloride, magnesium chloride, etc.) is used as an alternative to potassium chloride, good stability cannot be obtained. Of course, the condition of the product at high and low temperatures was not good.
