Description

The present invention relates to a body cleansing composition and a body cleansing method.

Most body cleansing compositions such as body soaps and shampoos used for cleaning skin and hair are viscous liquid (liquid) types, and the undiluted solution is filled in a pump container (liquid discharge container) as it is. It is used by discharging. In addition, a type in which a low-viscosity liquid detergent composition is filled in a container equipped with a pump equipped with a foaming function (hereinafter, also referred to as a foam discharge container or a container with a pump former) and discharged as fine foam. Body cleansers are also commercially available. When the body-cleaning agent composition is used by putting it in this foam discharge container, the foam of the cleaning agent composition can be directly picked up by a hand or the like and washed while being applied to the body. Therefore, there is an advantage that there is no need to whisk the detergent composition.

The body cleansing composition usually contains a cleansing component such as an anionic surfactant as a main component, but is required to have good usability in addition to cleansing power. For this reason, for example, in a hair washing composition, a component having a conditioning action (conditioning component) is often blended for the purpose of improving the squeaky hair during and after washing the hair. Patent Document 1 describes a detergent composition containing an acrylamide / acrylic acid / dimethyldiallyl ammonium chloride copolymer.

JP-A-2007-254573

Cationic polymers are mainly used as the conditioning component, and such a cationic component forms a complex with an anionic surfactant contained in a general body detergent composition and is liquid. There is a problem that the body detergent composition of the above causes precipitation and separation.
Patent Document 1 does not study suppressing separation or precipitation in a cleaning composition containing a conditioning component.
If the body cleansing composition is separated or settled, the appearance is poor and the cleansing power is lowered because a uniform cleansing composition cannot be obtained even if the body cleansing composition is discharged from the container. In addition, when separation or precipitation occurs, there is a problem that the container is clogged. In order to prevent the occurrence of such precipitation and separation, the body cleansing composition containing a conditioning component is often distributed as a viscous liquid type in a state where the component is dispersed in the system. However, when a conditioning component and an anionic surfactant are added to a body cleansing composition having a low viscosity, for example, a cleansing composition used for a container (foam discharge container) intended for foam discharge, it precipitates in the system. Separation occurs and becomes non-uniform, which causes the above problem. For this reason, no foam-discharged body cleansing composition having a high conditioning effect has been developed so far.

In recent years, for the purpose of reducing the burden on the environment, materials, and delivery costs, cleaning agents such as dishwashing detergents and laundry detergents are concentrated type (diluted with water to a predetermined ratio and used). ) Detergent composition is on the market. The body cleanser is also required to be compact from the above viewpoint.
From the above point of view, a high-concentration type that can be cleaned with a smaller amount than conventional use by increasing the concentration of cleaning components for the purpose of reducing the amount of cleaning agent used and reducing the burden on the environment. Body cleansers have been proposed. However, even with such a high-concentration type cleaning agent, the amount used may not be properly protected when it is used in the bathroom of a facility used by an unspecified number of people such as accommodation facilities and sports facilities. It is often used in the same amount as non-high-concentration type body cleansers, and has a greater burden on the environment. If a diluted solution of high-concentration type body cleanser can be used for body washing, it is thought that the amount of cleansing agent used can be reduced, but it is premised that the high-concentration type cleansing agent is diluted and used. For example, when a conditioning component is blended, separation or precipitation occurs after dilution, resulting in non-uniformity.

The present invention has been made to solve the above-mentioned problems, and although it contains a component having a conditioning action, it is stable without separation or precipitation even when diluted or has a low viscosity. An object of the present invention is to provide a body cleansing composition having a transparent appearance and which can also be used as a concentrated body cleansing composition.

As a result of diligent research to solve the above problems, the present inventors have used polydimethylmethylene piperidinium chloride as a component having a conditioning action, and the body detergent composition contains an anionic surfactant. Nevertheless, a stable body detergent composition that does not cause separation or precipitation before and after dilution (detergent composition (stock solution) and diluted solution obtained by diluting the detergent composition (hereinafter, also simply referred to as diluted solution)). I found that it can be done. It has also been found that this body cleansing composition can also be used as a concentrated body cleansing composition in which the diluted solution is used for washing the body because the diluted solution is stable. Furthermore, it has been found that this body cleansing composition can be suitably used as a body cleansing composition for a foam discharge container because separation and precipitation do not occur even if the viscosity of the undiluted solution and its diluted solution is low. The present inventors further studied and completed the present invention.

Therefore, the components of the body cleansing composition and its diluted solution are not separated during storage to deteriorate the performance, and the appearance is not impaired by precipitation or the like. Further, in the body detergent composition of the present invention, by using the component (A), the viscosity of the undiluted solution or the diluted solution is low (for example, the viscosity at 20 ° C. is 0 to 100 mPa · s, preferably 0 to 20 mPa). -S) Even in the case of s), since it is stable without separation or precipitation, when the body detergent composition or its diluted solution is filled in a discharge container such as a pump container or a foam discharge container and used, it may be caused by precipitation or the like. It can be used satisfactorily without clogging the discharge container.
