Description

  The present invention relates to an abrasive-containing cleaning agent comprising a porous abrasive having an irregular shape formed by substantially or chemically agglomerating or connecting substantially spherical bodies.

Conventionally, abrasive-containing cleaning agents have been widely used in daily goods, cosmetics, industrial fields and the like as powerful stain removers.
Normally, abrasive-containing cleaning agents are formulated with solvents, surfactants, etc. as cleaning components, and organic, inorganic, and natural particles as abrasives, either alone or in combination, and many related inventions have been reported. ing. For example, Patent Document 1 describes the combined use of a surfactant and an abrasive. However, when a surfactant is used, the environmental load is reduced and the skin is less irritating but has a low detergency. Generally known. In order to compensate for the lack of detergency, Patent Document 2 describes that a glycol solvent or an acetate solvent is used as a dye auxiliary agent, and Patent Document 3 describes that terpene hydrocarbon and terpene alcohol are used in combination as solvents. Yes.

However, it is said that when a solvent is used, the detergency is improved, but problems occur with respect to skin irritation and the environment. In addition, Patent Documents 1 and 3 have a problem that inorganic abrasives have high detergency but clog the water pipe or damage the skin. Although it is described that scrubbing material provides high cleaning power and scrubbing feeling, it can be applied to solid surfaces and human bodies to which dirt such as cutting oil used during metalworking and high-viscosity dirt such as grease are attached. It was said that it did not have sufficient cleaning power and the scrub feeling was not satisfactory.
As described above, the abrasive-containing cleaning agent is widely used in daily goods, cosmetics, industrial fields, etc. as a powerful stain remover, but the current situation is that it has advantages and disadvantages.

  The present invention has a high cleaning power suitable for removing dirt adhering to a hard surface or a human body, and contains an abrasive-containing cleaning agent excellent in a feeling of scrubbing and a feeling of refreshing during and after cleaning. The purpose is to provide.

As a result of intensive research to solve the above problems, the present inventor formulated a porous abrasive having an irregular shape formed by substantially agglomerating or connecting substantially spherical bodies. It has been found that an abrasive-containing cleaning agent which can be adapted to the above-mentioned purpose, and the present invention has been made based on this finding.
That is, the present invention is as follows.

1. 1. An abrasive-containing cleaning agent comprising a porous abrasive formed by agglomerating or connecting substantially spherical bodies. 2. The abrasive-containing cleaning agent according to 1 above, wherein the abrasive has a bulk density of 0.01 or more and 0.35 g / cm ³ or less. 3. The abrasive-containing cleaning agent according to 1 or 2 above, which is used for cleaning a hard surface.
4). 3. The abrasive-containing cleaning agent according to 1 or 2, which is used for cleaning a human body.

  The abrasive-containing cleaning agent comprising a porous abrasive having an irregular shape formed by physically or chemically agglomerating or connecting substantially spherical bodies of the present invention has a good scrub feeling and a solid surface or human body. It has a sufficient detergency against dirt with high viscosity such as cutting oil and grease used during metal processing attached to the surface. Surprisingly, the abrasive-containing cleaning agent of the present invention has a high detergency and also has an effect of imparting a refreshing feeling with little sliminess after cleaning during cleaning.

The present invention will be specifically described below.
The porous abrasive formed by agglomerating or connecting substantially spherical bodies of the present invention is an example in which random photographs were taken when observed with a stereoscopic microscope (Olympus: SZH) in FIGS. FIG. 3 shows an example of a photograph taken at random when observed with a real surface view microscope VE-7800 manufactured by Keyence Corporation. The aggregation or linking method may be based on a physical bond or a chemical bond. Moreover, it can be said that the abrasive formed by agglomerating or connecting substantially spherical bodies has a porous shape because there is a gap between the substantially spherical bodies.
On the other hand, the manufacturing method of the abrasive in the present invention is not particularly limited, and any method such as granulation, molding, mold molding, synthesis, and clipping may be used. The substantially spherical body of the present invention is not particularly limited, but may be anything such as a rough sphere, a sphere with few corners, a sphere shaped like a flat sugar, a sphere shaped like a grape bunch.

In addition, if the abrasive in the present invention is a porous shape having an irregular shape formed by physically or chemically agglomerating or connecting two or more substantially spherical bodies of 500 μm or less, a high detergency and scrub feeling are good. An abrasive-containing cleaning agent can be obtained. Preferably, the effect of the present invention is sufficiently exerted when the number of approximately spherical particles of 0.0001 to 100 μm is 5 or more. On the other hand, the particle diameter of the abrasive of the present invention is not particularly limited, but water: 80 parts, surfactant (Daiichi Kogyo Seiyaku Co., Ltd. Neugen XL-80): 10 parts, substantially spherical body: 10 parts. After mixing and dispersing, when filtering and drying with a JIS standard sieve and measuring the particle size, the particle size distribution is 1 to 600 μm, preferably 10 to 500 μm, more preferably 20 to 425 μm. An abrasive-containing cleaning agent that has high strength and good scrub feeling and gives a refreshing feeling after washing during washing can be obtained.
The particle diameter of the abrasive of the present invention is not particularly limited, and any length, diameter, width, height, etc. may be used.

  Further, the abrasive in the present invention is not particularly limited, for example, organic systems such as polyethylene and polyvinyl alcohol, inorganic systems such as silicic anhydride, aluminum silicate, aluminum oxide, polymers such as crystalline cellulose and chitosan, Examples thereof include biodegradable abrasives such as polylactic acid and polybutylene succinate, fibers such as cotton and rayon, natural systems such as walnut shells and shells, and food seasonings such as salt and sugar. In particular, an abrasive having a low bulk density is preferable because it has a high detergency against dirt from grease.

  In particular, organic, inorganic, polymer, biodegradable abrasives and the like are preferable from the viewpoint of detergency and scrub feeling. Further, for example, GUR2122 (polyethylene) manufactured by Ticona Japan Co., Ltd., Theolas TG-101 (cellulose) manufactured by Asahi Kasei Chemicals, and polystyrene foam are particularly preferable. The feeling can be improved, or a refreshing feeling after washing can be imparted during washing.

If the bulk density of the abrasive used in the present invention is a porous state of 0.35 g / cm ³ or less, a high detergency, a scrub feeling, and a feeling after use during washing are also improved. In particular the bulk density is preferably 0.01~0.32g / cm ^3, more preferably 0.10~0.30g / cm ^3, in particular 0.15~0.28g / cm ³ preferred.
On the other hand, those in which substantially spherical bodies are not observed, and it is judged that there is no aggregated connection of substantially spherical bodies or those that are not porous are not preferable because they have a weak detergency and poor scrub feeling.

Moreover, the hard surface as used in this specification means the surface to which dirt adheres in daily life. For example, screws, metal processed products, stainless steel, desks, resins, ceramics, artificial marble, flooring, glasses frames and lenses, telephones, glass, lasers, timber, leather, animals, metals, and the like. The abrasive-containing cleaning agent of the present invention is particularly suitable for removing dirt such as cutting oil, grease, soil dirt, and carbon adhering to screws and metal workpieces.
