DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an abrasive-containing detergent composition.

[0002]

2. Description of the Related Art Various factories, such as printing factories and car maintenance factories, mainly use various surfactants to wash grease, engine oil, tar and other oils and fats, printing inks, paints, etc. attached to hands and the like. The detergent used as a component is used. In addition, a detergent containing an abrasive (scrub material) is used to remove dirt that cannot be removed only by the surface active effect. It is known that this abrasive-containing detergent has better detergency than a detergent containing no abrasive, because the abrasive removes dirt.

Heretofore, powders of inorganic materials such as pearlite, alumina, silica and the like have been often used as abrasives. However, since these inorganic abrasives are insoluble in water and keep their particle state in the sewage forever, they accumulate in the drain pipes, clog the drain pipes, and cause difficulty in drainage treatment.

Recently, as a solution to the above problem, for example, use of an abrasive made of biodegradable plastic in which starch is added to polyethylene has been attempted. However, polyethylene or finely divided particles after starch degradation in sewage have been attempted. There is a problem that it is difficult to form a cake when flowing into the sewage treatment plant, and the amount of residue is increased.

Further, since all of these conventional abrasives have a high hardness, the tactile sensation when rubbing between hands during cleaning is hard and the cleaning sensation is not always satisfactory. There was also a problem that the effect of removing the dirt of the abrasive was not sufficiently exhibited.

[0006]

As described above, in the conventional detergent containing an abrasive, it is difficult for the abrasive to clog a water distribution pipe after use and to form a cake when flowing into a sewage treatment plant. There is a problem that the amount left behind increases,
Further, there is a problem that the hardness is high and the washing feeling during use is not satisfactory.

[0007] Therefore, the present invention is capable of easily removing most of the abrasives in a sewage treatment after use by separating and cake-forming the abrasives, and the abrasives that are not removed are decomposed by spontaneous decomposition, so that the wastewater is discharged. It is an object of the present invention to provide an abrasive-containing detergent composition which reduces processing, and further has a very good cleaning feeling and a cleaning effect at the time of use.

[0008]

The abrasive-containing detergent composition of the present invention for solving the above-mentioned problems comprises various surfactants, solvents,
It is characterized in that an abrasive made of wood powder is appropriately adjusted in particle size and contained in a detergent made of water or the like.

[0009]

The abrasive-containing detergent composition of the present invention is a wood, which is a natural organic substance whose abrasive components are naturally decomposed by water or underground microorganisms. In addition, wood flour often has a more elongated or complicated shape than a spherical one. Therefore, when the abrasive flows into the sewage treatment plant after use of the detergent, first, those that are floating can be easily separated, and those that are floating in water are also wet or swelled especially in sewage because of the above-mentioned particle shape. In this state, the particles are liable to be bonded to each other at the time of cake formation, and the remaining amount is small. Even if the fine particle portion is left, some of the remaining fine particles are made pollution-free by natural decomposition. In addition, even if large particles are left behind, they are naturally atomized and decomposed.

[0010] In addition, since wood flour has a lower hardness than conventional abrasives, especially when it is absorbed in the detergent composition of the present invention,
At the time of washing, the touch feeling when rubbing between hands is soft and the feeling of washing is good. Moreover, even if it rubs a little strongly, there is little danger of roughening the skin. In addition to the scraping action, the wood powder absorbs oil and the like and easily adheres to paints and the like, so that the washing effect is also good.

[0011]

Embodiments of the present invention will be described below.

First, any wood flour can be used as the wood flour as the abrasive component of the present invention. However, from the viewpoint of soft touch, soft wood lumber such as pine, cedar, cypress, or a mixture thereof is used. Is preferred. Of course, wood flour need not be produced by grinding especially for use in the present invention, but may be a by-product such as sawdust.

The particle size of the abrasive is preferably not more than 20 mesh pass, more preferably around 100 mesh pass, and it is also preferable to mix a plurality of types of wood flour selected by mesh. When the particle size is 20 mesh or less, the washing feeling when used for washing is deteriorated, and at the same time, it is difficult to be decomposed.

[0014] The compounding amount of the abrasive in the composition is preferably about 45% by weight or less, more preferably about 3 to about 20% by weight of the total composition. If it exceeds 45% by weight, the composition will not be creamy at the same time as the washing sensation will deteriorate.

The components of the composition other than the abrasive include a surfactant, a solvent and water.

The surfactant is preferably present in an amount of about 5% to about 40% by weight, more preferably about 10% to about 30% by weight of the total composition. An example of the surfactant is a nonionic surfactant such as polyoxyethylene. Examples thereof include alkylphenyl ether, laurelbetaine which is an amphoteric surfactant, and alkylbenzine methylammonium chloride which is a cationic surfactant.

The solvent is used to remove stains from printing inks and paints, and is contained in an amount of 0 to about 25% by weight of the total composition,
Further, about 10 to 20% by weight is preferable. Examples of the solvent used for this include water-soluble polyalkylene glycol ether solvents. Further, water is blended in a range from about 20 to about 80% by weight of the total composition.

In addition, if desired, conventional adjuvants, diluents, and diluents do not impair the beneficial properties of the composition.
And other additives such as fragrances, paints, discoloration inhibitors, fungicides and the like. In addition, an alkali source and a PH buffer such as carbonates and bicarbonates of alkali metals, monoethanolamine, triethanolamine, and hydroxides of alkali metals can also be used.

Next, a specific compounding example will be described.

First, four types of formulations A, B, C and D as shown in Table 1 below were prepared.

[0021]

[Table 1]

In Table 1, Debasic Esters (DBE) is a solvent made by Shell Chemical for removing paints, printing inks and oil stains. Liponox NC-70,
NC-100 and NC-150 are nonionic surfactants of Lion Corporation. Amphitol 24B is an amphoteric surfactant manufactured by Kao Soap Co., Ltd. Sanizol B-50
Is a cationic surfactant manufactured by Kao Soap Co., Ltd. Wood flour is crushed radiator pine from New Zealand and has a particle size of 100 mesh pass.

The detergent compositions obtained from these formulations A, B, C, and D are creamy, all of which are excellent in removing dirt, and have a softer touch than conventional detergent compositions containing abrasives. It has very good cleaning effect and cleaning feeling, and can be widely used as an abrasive-containing detergent. Also, after enclosing the detergent composition of the above formulation in a container,
Unless a large amount of various fungi were added, the decomposition of the wood flour did not occur, and there was no immediate deterioration and the storage stability was good.

When the detergent composition is poured into a sewer system after use, the above-mentioned 100-mesh pass wood flour as an abrasive is scattered into the sewage. It does not cause clogging. When flowing into the sewage treatment plant, the floating material can be easily separated, and the floating material can be easily caked and removed. In this case, even if a small amount of fine particles are left, they are naturally decomposed by water or underground microorganisms and made non-polluting.

[0025]

As described above, the present invention is an abrasive-containing detergent composition characterized by containing wood powder as an abrasive, as described in the claims, so that the water distribution pipe is clogged. Without waste, it can be easily removed in a sewage treatment plant, and the remaining particles can be naturally decomposed, and can be used as a pollution-free detergent.

Also, wood flour has a low hardness and also has a hygroscopic property, so that it has a soft touch, and in addition to the shaving action, also has a dirt removing action due to absorption and adhesion. Since there is no problem, there is no restriction on the particle size of the abrasive, and by appropriately selecting the abrasive, it is possible to provide a detergent having better cleaning feeling and cleaning effect.
