Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention has an excellent detergency as a detergent composition, and has a mild action on the skin (finishes the skin smoothly and further suppresses itching of the skin), and further wash. The present invention relates to a detergent composition which does not feel slippery after rising and has a good feeling in use.

2. Description of the Related Art
Anionic surfactants such as alkyl sulfates, polyoxyethylene alkyl ether sulfates and α-olefin sulfonates are widely used as surfactants for detergent compositions. However, all of these anionic surfactants have the drawback of inducing skin irritation to varying degrees.

Further, consumers' awareness of cleanliness is increasing year by year, and cleanliness is the basis of daily life, and in particular, cleaning agents are required to have various functions and effects. Cleaners such as body cleaners and facial cleansers have only the basic performance as a cleaner to clean and remove extrinsic stains such as dust and microbes (bacteria), and endogenous stains such as sebum, sweat, and dead keratin. There is a need for a function that makes the skin not so tight and smooth and smooth, and that there is no slimy skin after washing and a refreshing feeling of use. Further, in recent years, the number of patients with atopic dermatitis has increased, and there has been a strong demand for a cleaning agent that suppresses itching of the skin after cleaning.

[0004] Generally, a succinic acid type anionic surfactant is used as a surfactant used for its mild action on the skin, but its detergency is poor and unsatisfactory. In addition, the highly safe amino acid type anionic surfactant has a drawback that the feeling after washing is slimy.

In addition, the feeling after washing is refreshing,
A fatty acid salt having a good feeling in use is not preferable for those who generate scum in hard water, have poor detergency, and have a high pH of 10 to 11 and are vulnerable to alkalis.

Further, for the purpose of improving the function and the feeling of use, as the cleaning composition, a cleaning composition containing a scrubbing agent, a clay mineral, a polymer compound or the like has been proposed. For example, a detergent containing montmorillonite as a clay mineral (JP-A-1-190622). A detergent composition containing polymer particles having an average particle diameter of 100 to 1000 μm and having a specific elastic modulus (JP-A-2-15169).
No. 3) is disclosed.

However, when the above-mentioned cleaning agent is applied to a cleaning agent containing a higher fatty acid soap or the like, precipitation of montmorillonite occurs, and it has a sticky feeling, and the feeling of use is not sufficient. Further, although the above-mentioned detergent composition is excellent in the cleaning effect, the effect is insufficient in terms of smoothness of the skin, feeling of use such as refreshing after washing, etc., and it is not yet satisfactory.

That is, the present invention has an excellent detergency, and also has a mild action on the skin (finishes the skin smoothly and further suppresses itching of the skin), and further, the feel after washing is slimy. It is an object of the present invention to provide a detergent composition having a good feeling in use.

[0009]

[Means for Solving the Problems] A first aspect of the present invention for achieving the above object is to provide a detergent composition comprising a bamboo salt, an anionic surfactant and water. is there. Further, claim 2 of the present invention is characterized in that Zn ions are 0.00
05-0.05 wt%, Mn ion 0.0005-
The cleaning composition according to claim 1, wherein a bamboo salt is contained in an amount of 0.05% by weight.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION As the bamboo salt used in the present invention, one kind or two or more kinds of rock salt, sun salt, fine salt, seawater dried product, mineral spring water dried product, etc. are appropriately selected, and bamboo salt (3 years Stuffed in a suitable amount), more preferably red leaf powder, wormwood, and bamboo leaves for about 1 cm, and then at the end, fertilized loess in the mountains (9 times fine mesh, shade Dry it and knead it tightly) and hold it for about 2 cm. Pine trees are laid in a ceramic pot made of loess, sprinkled with pine trees, and then baked (bath temperature 1,0
00 ° C or higher). After 24 hours, it is taken out (only the column of salt remains at this time) and ground. After crushing, it is put in a new bamboo tube by the same method as the beginning, and this is repeated 2 to 9 times to obtain the bamboo salt of the present invention.

The bamboo salt of the present invention has a Zn ion content of 0.000.
5 to 0.05% by weight, Mn ion 0.0005 to 0.
It is preferable to contain 05% by weight. If the amount of Zn ion is less than 0.0005% by weight, the action on the skin (finishing the skin smooth and suppressing itching of the skin) may not be sufficiently exerted, and if it exceeds 0.05% by weight, the detergency and the skin are not affected. Besides reducing the action, it may affect the stability of the dosage form. Further, the Mn ion is less than 0.
If it is less than 0005% by weight, the effect on the skin (finishing the skin smooth and suppressing itching of the skin) may not be sufficiently exerted, and if it exceeds 0.05% by weight, the detergency and the effect on the skin decrease. In addition, it may affect the stability of the dosage form. Therefore, by adjusting the number of times to bake bamboo and bake it as described below,
It is preferable to manufacture the bamboo salt so as to obtain a bamboo salt containing an amount of ions and an amount of Mn ions. In addition, as a quantitative analysis method of Zn ion and Mn ion in bamboo salt, an atomic absorption analysis method, an ion chromatography analysis method, an IPC emission analysis method and the like are performed.

In order to specifically obtain the bamboo salt of the present invention, it is preferable to go through the baking step 2 to 9 times as described above.
It is particularly preferably 3 to 6 times, and if it is less than 2 times, the amount of active ingredients such as Zn ions and Mn ions in the bamboo salt may be insufficient, and the effect of the present invention may not be obtained. In some cases, the effects of improving the detergency and the action on the skin, which are the objects of the present invention, may not be achieved any further, and the manufacturing process of bamboo salt becomes complicated as it affects the stability of the dosage form, resulting in a manufacturing cost. It tends to be high.

The average particle size of bamboo salt is 0.01 to 10
mm particles are preferred, more preferably 0.1-5 mm
It is. If it is less than 0.01 mm, bamboo salt tends to be inferior in handleability, and if it exceeds 10 mm, it tends to cause discomfort and damage to the skin.

The amount of bamboo salt to be added to the detergent composition of the present invention can be appropriately selected according to the actual application form, but particularly in the case of liquid, paste-like or cream-like formulations, the cleaning agent is used. It is preferable to add an amount equal to or higher than the saturated solubility in water in the composition. If it is less than the saturated solubility, the bamboo salt does not show crystallinity by dissolving in the detergent composition, and the crystalline bamboo salt gradually dissolves over a long period of time even if the manufacturing method is devised and added. In some cases, the desired effect may not be achieved. Here, the term “saturation solubility or higher” means that the amount of the bamboo salt dissolved in water in the detergent composition is equal to or higher than the limit, and it means 26.5% by weight or more based on the total weight of the bamboo salt and water.

The upper limit of the amount of the bamboo salt used in the present invention is not particularly limited, but if it is extremely large, the function as a detergent is impaired, so 90% by weight or less based on the total amount of bamboo salt and water is used. preferable.

As the anionic surfactant used in the present invention, fatty acid soap, POE alkyl ether carboxylate, tetradecene sulfonate, higher fatty acid ester sulfonate, alkyl sulfosuccinate, higher fatty acid amide myrphonate, alkyl Allyl sulfonate, higher alcohol sulfate ester salt, POE alkyl ether sulfate ester salt, glycerin fatty acid ester sulfate salt, higher fatty acid alkylolamide sulfate ester salt, alkyl phosphate ester salt, acyl glutamate, acyl asparaginate, acyl sarcosine Examples thereof include salts, acylamino acid salts such as acyl-β-alanine salts, and collagen hydrolyzate acyl compounds. In each case, alkali metal salts such as sodium, potassium and magnesium, organic amine salts such as triethanolamine, alkaline amino acid salts such as L-lysine and the like can be used. In particular, among the above-mentioned anionic surfactants, a bamboo salt is added when a tetradecene sulfonate, a higher alcohol sulfate ester salt, or a POE alkyl ether sulfate ester salt, which is a surfactant that easily induces skin irritation, is added. When used in combination, the mild effect on the skin, which is the object of the present invention, is remarkably exhibited.

The amount of the anionic surfactant used in the present invention is not particularly limited, but is preferably 2% by weight or more,
More preferably, it is at least 5% by weight. If it is less than 2% by weight, it may be difficult to obtain satisfactory cleaning power as a cleaning agent.

The detergent composition of the present invention contains bamboo salt and an anionic surfactant, but water is required to dissolve these substances, and a suitable amount of water is other liquid components. However, 5% by weight or more is desirable in order to dissolve the anionic surfactant.

Further, in addition to the anionic surfactant, it is also preferable to use an amine oxide or a fatty acid diethanolamide in order to improve other foaming properties and to impart appropriate viscosity. In addition, by using a pearlescent agent such as fatty acid glycol diester and a thickening agent such as hydroxyethyl cellulose together, separation and aggregation of bamboo salt crystals can be prevented, and long-term stability over time can be improved. Becomes

The above-mentioned components are essential components in the detergent composition of the present invention, but other components may be appropriately added to the composition within the range where the object of the present invention is achieved. I can.

That is, oily components such as higher alcohols, silicone oils, lanolin derivatives, protein derivatives and fatty acid esters of polyethylene glycol, nonionic surfactants such as fatty acid alkanolamides, polyoxyethylene alkyl ethers and alkyl amine oxides, Amphoteric surfactants such as alkylamidopropyl betaine, water-soluble polymers such as hydroxypropylmethyl cellulose and hydroxyethyl cellulose, cationic polymers [Polymer JR
