Description

[Detailed description of the invention] The present invention relates to a bulk density detergent composition with good solubility.

Heavy-duty agents are available on the market in the form of grains, grains, or powder. Liquid anti-S++ has the advantage that it does not become too hypertensive because the active ingredient can be highly concentrated, and it is easy to handle because it is a liquid.
However, the problem is that the detergency is inferior to granular detergents because the alkali builder formulation is difficult. Also,
Bottles containing liquid detergent also cost less than cartons of granular detergent.

On the other hand, granular detergents do not require a single prefecture to incorporate alkaline builders, and have become the mainstream heavy-duty detergents for clothing.

However, current granular detergents have an average oil diameter of 200 to
It has a bead-like hollow 1:)ξ of about SOOμn+, and as a result, the bulk is 0.3? /cc 4':
, j lσ becomes low, and M (there is a problem that there is a grudge against the amount).

For this reason, current granular detergents not only have high transportation costs, but also require a considerable amount of space for storage and display. In addition to this, even if the dosage and measuring method of the drug used in C1 households are clearly specified, is this? The disadvantage was that it was not convenient for consumers to do so.

So here are the drawbacks of current granular anti-firmness! 'If I erased the bulk density detergent, Li14 is straddling it. 0. .

By increasing the bulk density of the agent, the active ingredient can be

No more tension. Moreover, if it can be made into tablets one step further, it will be extremely easy to handle, for example, it can be used for one use + 11 times less than the previous one.

The biggest challenge in increasing the bulk density of "Arai T11" is how to solve the problem of detergent solubility.
Unlike Western countries, where it is customary for ordinary households to use hot water for every wash, in Japan it is common to use the cold water supplied from the tap, so even cold water can be used in a short time. It needs to be easily soluble.

As a result of intensive studies based on the four points mentioned above, the present inventors have found that if anhydrous hydrozulfite and peroxide are blended into a detergent composition, the detergent composition can be made more difficult by compression shaping, etc. However, they discovered that the composition dissolves in cold water in a short time, and based on this knowledge, they completed the present invention.

That is, the commercial e-detergent composition of the present invention is characterized by containing anhydrous hydrosulfide and peroxide.

Anhydrous hydrosulfide (Aby, min) and peroxide (

It is determined as appropriate depending on the type of minute. Specific examples of the peroxide of component B include lithium peroxide, potassium percarbonate, thorium perborate, and 1f-1 imitative potassium. These B components also act as alkali builders.

The detergent composition of the present invention may contain an anti-drug component used in ordinary granular gamma agents. These ingredients include alkylbenzene sulfonates, alkyl sulfonates, α-olefin sulfonate salts, alkyl sulfates, alkyl polyether sulfates, anionic surfactants such as fatty acid soaps, alkyl ethoxylates,
Anionic compounds such as alkylphenyl ethoxylates and alkyl alkanolamides, amphoteric surfactants such as alkyl betaines, inorganic builders such as sodium carbonate, sodium carbonate, sodium bicarbonate, sodium tripolyphosphate, zeolite, and sodium sulfate. organic builders such as sodium citrate, sodium ethylenediaminetetraacetate, and sodium nitrilotriacetate. In addition, fluorescent brighteners, enzymes,
Other additives may also be included.

The detergent composition of the present invention includes, for example, the above-mentioned A as a detergent component.
Both components B can be combined and easily molded by appropriate means. The shape of the detergent composition after molding can be spherical, cylindrical, or
You can choose any shape, such as a tablet, and the size is up to you; for example, one molded product can be large enough to cover the amount of detergent needed for one wash.

The bulk density of the detergent composition of the present invention is not particularly limited.
Generally, 0.5 f/cc or more is appropriate, and preferably o,s to 1.2 t/cc.

Furthermore, since anhydrous hydrosulfide is easily decomposed by moisture, it is wiser to have as little moisture as possible in the detergent composition.

According to the detergent composition of the present invention, by blending anhydrous hydrosulfide and peroxide with a disintegrant in water, the detergent composition does not have a hollow bead shape unlike conventional granular detergents, but has excellent dissolution even though it has a high bulk density. It exhibits properties and is capable of increasing its density.

The detergent compositions of the present invention are particularly useful as heavy duty laundry detergents.

Example A powdered detergent having a composition consisting of 50 wt% linear alkylbenzene sulfonate, 20 wt% zeolite and 30 wt% Glauber's salt was mixed with A shown in Table 1 below.

B Both components (both powder) 7i - After uniformly mixing with the specified mixing ratio, place in a container with an inner diameter of 3 crnφ and a height of 1 crn, cover with a lid, and apply a load of 80 kg (pressure of 4/- to 11). Made into a tablet. The mWf property and (i'b ("f") force of this sample were evaluated according to the following procedure, and the results are shown in Table 1.
