2. Description of the Related Art Generally, when heavy oil stains, metal powder stains, film-formed stains, etc. adhere to the surface of the skin, they are combined with sweat and fatty acids coming out of the skin, resulting in skin grooves, sweat holes. It is difficult to easily remove stains such as in fingerprints. In order to remove such stubborn dirt, powdered soap containing an inorganic mineral abrasive such as silica sand and an alkali builder is usually used. However, although this powdered soap has good dirt removal properties, it is easy to spill unless wet with water before use, and is uneconomic.After use, the specific gravity of silica sand is large, and it sinks into the flowing pipe, In severe cases, pipes may be clogged, and those containing an inorganic mineral-based abrasive such as silica sand may cause hand roughening when used frequently. In addition, a paste-like detergent containing a solvent, a surfactant, silica sand and the like is also used, but this is good for dirt removal, but it is difficult to use because of its high viscosity, and silica sand is also used. Since it contains, depending on its shape, it has irritation to the skin as in the case of the above-mentioned powdered soap, and causes problems such as rough hands. Further, a creamy detergent using a synthetic scrub agent having little skin irritation is also known, but this has a drawback that it is poor in the removability of filmed dirt such as paint, and the dirt removing effect is low. Not enough. In this way, the skin is less irritating, and the skin groove, sweat holes,
A body cleaner that can effectively remove dirt in fingerprints and stubborn dirt formed into a film has not been found so far.

[0003]

SUMMARY OF THE INVENTION Under such circumstances, the present invention is particularly useful as a hand cleaner, and is used to form a stubborn dirt such as a skin groove, a sweat hole, dirt in a fingerprint or paint. The object of the present invention is to provide a cleansing composition for the body that can effectively remove such substances, has low irritation to the skin, and does not cause clogging of piping.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies to develop a personal cleansing composition having the above-mentioned preferable properties, and as a result, have found that terpene hydrocarbons and terpene alcohols have a specific particle size. It has been found that a natural scrub agent or a synthetic scrub agent and a fatty acid salt having a predetermined ratio as essential components, respectively, and a composition having a specific range of pH and viscosity can achieve the object,
Based on this finding, the present invention has been completed. That is, the present invention relates to (A) 5 to 30% by weight of a terpene hydrocarbon and / or terpene alcohol, and (B) an average particle diameter of 3
1.0 to 30% by weight of a natural scrub agent and / or a synthetic scrub agent of 0 to 500 μm, and (C) a fatty acid salt of 1.0 to 3
0% by weight as an essential component and a pH of 4.0
The present invention provides a creamy personal cleansing composition characterized by having a viscosity at -8.0 and a temperature of 20 ° C of 5-100 poise. Hereinafter, the present invention will be described in detail. In the composition of the present invention, a terpene hydrocarbon and / or terpene alcohol is used as the component (A). Examples of the terpene hydrocarbon include, but are not limited to, d-limonene, hydrogenated limonene, pinene, myrcene, terpinene, camphene, tricyclene, and terpinolene. On the other hand, as the terpene alcohol, for example, linalool,
Examples include, but are not limited to, myrsenol, menthol, geraniol, terpineol, borneol, hydrogenated terpineol, and the like.

In the composition of the present invention, as the component (A), one kind of the terpene hydrocarbon may be used, two or more kinds thereof may be used in combination, or one kind of the terpene alcohol may be used. Alternatively, two or more kinds may be used in combination. Further, one or more terpene hydrocarbons and one or more terpene alcohols may be used in combination. The content of the component (A) in the composition of the present invention is 5 to 5.
It must be in the range of 30% by weight. If the content is less than 5% by weight, sufficient detergency cannot be obtained and 30
If the amount exceeds 10% by weight, the detergency does not improve much for the amount, and it is rather economically disadvantageous. In the composition of the present invention, a natural scrub and / or a synthetic scrub is used as the component (B). Examples of the natural scrub agent include apricots, peaches, corn, pulverized nuclides such as walnuts, peanuts, hull powder such as sesame, protein powders such as casein, kinako, flour, chitin, and polysaccharide powders such as cellulose. However, the present invention is not limited to these. On the other hand, examples of the synthetic scrub agent include polyethylene, polypropylene, polystyrene, polyvinyl chloride, and the like, but are not limited thereto. These natural scrubbing agents and synthetic scrubbing agents have an average particle diameter of 30-5.
It must be in the range of 00 μm, preferably 100-300 μm. If the average particle size is less than 30 μm, the removability of the film-formed dirt or the like is insufficient.
If it exceeds μm, the feeling of use will deteriorate.

In the composition of the present invention, as the component (B), one natural scrub may be used, two or more natural scrubs may be used in combination, or one synthetic scrub may be used. , May be used in combination of two or more,
In particular, it is preferable to use one or more natural scrubbing agents and one or more synthetic scrubbing agents in combination in order to achieve high detergency. It is necessary that the content of the component (B) in the composition of the present invention is in the range of 1.0 to 30% by weight, preferably 5 to 20% by weight. When this content is 1.0
If the amount is less than 30% by weight, the removability of skin crevices, sweat holes, stains in fingerprints and film-formed stains is poor, and if it exceeds 30% by weight, the viscosity of the detergent composition becomes high and the workability decreases. In the composition of the present invention, a fatty acid salt is used as the component (C). Examples of the fatty acid constituting the fatty acid salt include caprylic acid, capric acid, lauric acid, myristic acid,
Saturated fatty acids such as palmitic acid, stearic acid, behenic acid, lignoceric acid, cerotic acid, montanic acid, melicic acid, and hydroxystearic acid, and unsaturated fatty acids such as oleic acid, linoleic acid, linoleic acid, ricinoleic acid, and erucic acid However, the present invention is not limited to these. These fatty acids are used in the form of salts. Examples of the salts include alkali metal salts, alkaline earth metal salts, ammonium salts, mono-, di-, and tri-ethanolamine salts. In particular, potassium salts are preferred. In the composition of the present invention,
As the component (C), one kind of the fatty acid salt may be used,
Two or more kinds may be used in combination, and the content of the fatty acid salt in the composition is 1.0 to 30% by weight, preferably 5 to 30% by weight.
It must be in the range of ~ 15% by weight. When the content is less than 1.0% by weight, the viscosity of the composition becomes low,
The scrubbing agent of the component (B) may be liable to settle, and if it exceeds 30% by weight, the viscosity of the composition increases and the workability decreases.

The personal cleansing composition of the present invention may optionally contain, if desired, various additives conventionally used in personal cleansing agents, such as surfactants, glycol ethers and anti-inflammatory agents. Can be. Here, as the surfactant, an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, and the like can be used alone or in combination, and particularly, biodegradability, skin irritation, and rinsing From the viewpoint of properties and the like, amino acid-type amphoteric surfactants are preferred. Examples of the glycol ether include, for example, mono-, di-, tri-, and tetra-alkylene glycol alkyl ethers, mono-, di-, tri-, and tetra-alkylene glycol phenyl ethers. Is, for example, Ougon liquid, mugwort liquid, peony liquid,
Plant extracts such as saxifrage liquid, aloe extract, wild rose oil, horse fat, horse oil, allantoin, dipotassium glycyrrhizinate and the like can be used. In the composition of the present invention, it is necessary to adjust the pH to the range of 4.0 to 8.0. Adjustment of the pH, if necessary, citric acid, tartaric acid, lactic acid, glycolic acid, gluconic acid,
The reaction is performed using a hydroxycarboxylic acid such as malic acid, or a dibasic acid such as oxalic acid, malonic acid, succinic acid, glutaric acid, or adipic acid. When the pH is out of the above range, irritation to the skin occurs, and the rinsing property tends to decrease. The composition of the present invention has a temperature of 20.
It is necessary to adjust the viscosity at 5 ° C. in the range of 5 to 100 poise. The adjustment of the viscosity is usually performed by adjusting the amount of the fatty acid salt of the component (C). If the viscosity is less than 5 poise, the scrubbing agent of the component (B) tends to settle, and the object of the present invention cannot be sufficiently achieved. If the viscosity exceeds 100 poise, the composition becomes gel-like and the workability is reduced. As a method of using the personal cleansing composition of the present invention, usually an appropriate amount of a creamy undiluted solution is taken and thoroughly rubbed against a soiled surface.
After the dirt is completely lifted off, rinsing with water is preferable, and it is particularly preferable to use it for a hand cleaner.
