Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to detergents, and in particular to detergents particularly suitable for the skin.

[Conventional technology]

Conventionally, skin cleansers containing inorganic powder as an abrasive have been known in order to improve cleaning performance.

[Problem to be solved by the invention]

By the way, there were 14 points about the laundry detergent containing inorganic powder as an abrasive, especially as it irritated people's skin.

It’s true that it’s for the skin and it’s expensive! For example, cleansing creams are known as multi-drug products with pre-power, but cleansing creams have the problem of being extremely expensive.

The technical object of the present invention is to solve the above-mentioned conventional problems and to provide an avant-garde agent that is inexpensive and particularly suitable for use on the skin.

[Means to solve the problem]

In order to solve the above-mentioned problems, the first cleaning agent of the present invention is formed by a solid method and includes flexible fibrillated short fibers and a solid surfactant.

The second cleaning agent of the present invention is a powder cleaning agent and is formed by containing flexible fibrillated short fibers to which a surfactant is attached.

The third cleaning agent of the present invention is a paste-like cleaning agent, and is formed by containing flexible fibrillated short fibers impregnated with a surfactant in a fluid state.

[Effect]

The fibrillated short fibers are washed and polished on 9 sides, and the surfactant emulsifies the oily deposits. Fibrillated short fibers do not bias the skin surface.

The present invention will be explained in more detail below.

The first detergent of the present invention uses a solid surfactant along with flexible fibrillated short fibers.

Examples of the solid surfactant used with the fibrillated short fibers include machine kneaded soaps, border soaps, and the like. In addition, specific examples include anionic surfactants, cationic surfactants, amphoteric surfactants, nonionic surfactants, and other surfactants that are solid at dense temperatures.

It should be noted that surfactants that are less irritating to dishes, and especially less irritating to the skin, are preferred.

The flexible fibrillated short fibers used in conjunction with the solid surfactant are flexible, and in particular have a surface hardness in the range of 30 to 80, preferably 40 to 70, when tested according to the ASTM 02240 test method. It is good to have the following.

Examples of fibers that may be used in the present invention include synthetic resin pulp fibers such as acrylic, polyester, polyolefin, and nylon.

These fibers may be used alone or in combination.

Specifically, among the above fibers, for example, synthetic polyolefin pulp fibers are desirable as the fibers used in the present invention. For example, synthetic polyolefin pulp fibers are preferred because they are highly flexible and hardly damage dishes or the like during cleaning.

The fibers used in the present invention are preferably hydrophilic fibers. Hydrophilicity may be an inherent property of the fiber material, but for example, if a hydrophilic compound such as polyoxyethylene alkyl ether is mixed into the resin, the properties of a hydrophobic resin such as synthetic polyolefin may be modified. It may also be a characteristic that has been created by

Among the above-mentioned fibers, synthetic polyolefin pulp P! is a particularly flexible fiber. i fiber is preferable. For example, synthetic polyolefin pulp fibers hardly cause any damage to the skin when washing.

The fibers used in the present invention are short fibrillated fibers.

The fineness of the fibrillated short fibers used in the present invention is 1 to 5.
0LLm is preferred.

In the present invention, in addition to the above surfactant and fibrillated short fibers, preservatives, antioxidants, fluorescent dyes, vegetable waxes, animal waxes, triglycerides, polyhydric alcohols, fragrances, colorants, and fungicides are added. It is preferable to use compounds that are added to ordinary cosmetic soaps, such as, but not limited to, the purpose of the invention.

The first cleaning agent of the present invention is formed containing a solid surfactant and fibrillated staple fibers. Preferably, each component is mixed uniformly.

The weight ratio of the fibrillated short fibers mixed into the solid surfactant is preferably 5 to 95% based on the total weight of the solid surfactant and the fibrillated short fibers. The weight ratio of the solid surfactant is preferably 5 to 95% based on the total weight including the weight of the fibrillated short fibers.

The first cleaning agent of the present invention may be manufactured by the following method. For example, a neat sorb consisting of a surfactant is heated and dissolved, and the above fibrillated short fibers are mixed in the fluidized neat sorb at the above weight ratio, and fragrances, colorants, fungicides, etc. are also added in appropriate proportions. Mix, pour into a frame and cool.

Alternatively, the following method may be used. That is, the above-mentioned fibrillated short wA fibers are mixed into the neat sorb in a fluid state at the above-mentioned weight ratio, and then the fibrillated short wA fibers are mixed into the neat sorb in a fluid state. ! The neat sorb mixed with fiber is made into a bon-like shape, and the moisture content is 13
Dry until it becomes ~14% by weight, knead with a roller,
Next, press it with a brochure to make it harden well.

In the second detergent of the present invention, a solid surfactant is attached to fibrillated short fibers.

The fibrillated short fibers and solid surfactant used in the second detergent may be the same substances as the fibrillated short fibers and the surfactant already described in the first detergent. In addition to fibrillated short fibers and surfactants, the second detergent of the present invention may be used in the first detergent) multi-component as already described in the first detergent multi-component. Other compounds may be included to the extent that they do not constitute the object of the invention.

Specifically, the compound in the pond is fibrillated! It may be attached to the a-fibers or may be mixed together with fibrillated short fibers.

The proportion of fibrillated short fibers or surfactant used in the second detergent may also be the same as that already described for the first detergent.

The second cleaning agent of the present invention may be manufactured, for example, by the following method.

The above-mentioned fibrillated short fibers are mixed into the neat sorb in a fluid state at the above weight ratio, and then the neat sorb with the fibrillated short fibers mixed therein is shaped into a ribbon, dried to a moisture content of about 10%, and then rolled with a roller. Knead to form flakes.

In the third cleaning agent of the present invention, fibrillated short wA fibers are impregnated with a fluidized surfactant.

The fibrillated short fibers and surfactant used in the third cleaning agent may be the same substances as the fibrillated short fibers and surfactant already described in the first cleaning agent, but the surfactant is not necessarily at room temperature. It does not need to be solid. That is, examples include anionic surfactants, cationic surfactants, amphoteric surfactants, nonionic surfactants, and other surfactants that are liquid at room temperature, or water-soluble surfactants thereof. Incidentally, surfactants that cause little irritation to the skin, especially those that do not irritate the skin, are preferred.

In addition to fibrillated short fibers and surfactants, this third detergent also contains other compounds that may be used in the first detergent, such as those already described in the first t5%l agent. It may be included as long as it does not impair the purpose of the invention.

The ratio of the fibrillated short fibers or surfactant used in the third cleaning agent may also be in accordance with the ratio already described for the first cleaning agent.

The third cleaning agent of the present invention may be produced, for example, by the following method.

That is, for example, the above-mentioned fibrillated short fibers are mixed in the above-mentioned weight/l ratio into a fluid neat sorb having a water concentration of 10 to 90% by weight.
