Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a tablet-type nonionic detergent composition containing a nonionic surfactant as a main component, which does not exude the nonionic surfactant under high temperature and high humidity and is excellent in strength and solubility. .

[0002]

2. Description of the Related Art Nonionic surfactants generally have a low foaming property, their detergency is hardly affected by the hardness of water, and they are particularly excellent in dirt dispersibility and stain dispersibility at low temperatures. In addition, it is an excellent surfactant with good biodegradability, low environmental load, low toxicity and no safety problem. On the other hand, from the viewpoint of ease of use as a detergent, a tablet-type or divided-pack type detergent is demanded instead of the conventional granular detergent. However, nonionic surfactants are generally liquid at room temperature, and even when a tablet-type detergent containing the same is manufactured, the nonionic surfactant exudes and the tablet surface becomes sticky, making it difficult to handle. Further, when tablets are used as the detergent, there is a problem that solubility is deteriorated. As a solution to this problem of solubility, for example, in JP-A-5-65500, a specific inorganic salt is added. However, this technique is effective under a relatively high water temperature of about 20 ° C. under a sweet condition, and in practice, the water temperature becomes 10 ° C. or less during the washing in winter. Therefore, under such severe conditions, the solubility of the tablets according to the above technique was not sufficient.

Further, the nonionic surfactant has a small binder force, and if it is simply made into tablets, the strength as tablets is insufficient, and there is a problem that it collapses during storage or transportation.

[0004]

Therefore, the present invention provides a tablet-type nonionic detergent composition which is free from stickiness on the tablet surface under high temperature and high humidity, and has excellent solubility and strength in cold water of the tablet. The purpose is to

[0005]

Means for Solving the Problems As a result of extensive studies on the above problems, the present inventor found that if a specific nonionic surfactant, a clay mineral and an oil-absorbing carrier were used in combination, the tablet surface under high temperature and high humidity could be improved. It was found that stickiness can be effectively prevented and that the strength of the tablet-type detergent can be improved. Furthermore, it was found that the addition of a clay mineral deteriorates the solubility of the tablet-type detergent because it becomes hydrophobic, but it was found that this problem can be effectively improved by using a disintegration accelerator together. By the way, it has long been known that clay minerals adsorb to fibers, especially cotton cloth, and exert a softening effect,
When used in combination with a nonionic surfactant, it was difficult to adsorb to the cloth and the desired softening effect did not appear. However, it has been found that the problem of softness reduction can be effectively solved by using the above specific nonionic surfactant and clay mineral in combination with an oil-absorbing carrier and a disintegration promoter. The present invention has been made based on such novel findings. That is, the present invention provides (1) an alcohol type nonionic surfactant or a fatty acid alkyl ester alkoxylate nonionic surfactant, (2) a clay mineral,
The present invention relates to a tablet-type nonionic detergent composition containing (3) an oil-absorbing carrier and (4) a disintegration accelerator.

The nonionic surfactant is preferably 10 to 50% by weight, more preferably 10% by weight in the granular nonionic detergent composition.
-40% by weight, particularly preferably 10-35% by weight. When this amount is less than 10% by weight, the concentration of the nonionic surfactant in the obtained tablet becomes too low, the detergency is insufficient, and the strength of the tablet is apt to be lowered, which is not preferable. On the other hand, if it exceeds 50% by weight, the nonionic surfactant exudes from the tablet, the surface of the tablet becomes sticky, and the handleability is likely to deteriorate, which is also not preferable. The clay mineral used in the present invention has the function of improving the strength and solubility of the tablet detergent. As such a clay mineral, one that belongs to the smectite group and has a crystal structure of a dioctahedral type three-layer structure or a trioctahedral type three-layer structure can be preferably used. Such a clay mineral has a cleavage property and has a layered structure. This clay mineral has a smaller oil absorption amount than the oil absorbing carrier described below. In addition, clay minerals form chemisorption due to hydrogen bonding between non-ionic surfactants between crystal layers,
It has the property of being retained inside clay minerals. In addition, as the clay mineral retains the nonionic surfactant inside,
It has the property of swelling.

Clay minerals that can be preferably used in the present invention are
Preferably the oil absorption is less than 80 ml / 100 g, more preferably 30-70 ml / 100 g, while the bulk density is preferably
The amount is 0.1 g / cc or more, particularly preferably 0.2 to 1.5 g / cc. Specific examples of such clay minerals include, for example, montmorillonite (oil absorption: 50 ml / 100 g, bulk density: 0.3 g / c as a clay mineral having a dioctahedral type three-layer structure).

It is contained in an amount of 20% by weight, particularly preferably 3 to 10% by weight. If this amount is less than 0.1% by weight, the fluidity of the resulting detergent particles under high temperature and high humidity tends to be significantly reduced. On the other hand, if it exceeds 30% by weight, the resulting detergent particles become too hydrophobic, and the solubility of the detergent tends to deteriorate, which is not preferable. The oil-absorptive carrier used in the present invention has a function of preventing exudation of nonion under high temperature and high humidity and preventing stickiness of the tablet surface. The oil-absorptive carrier is a porous fine powder sufficient to adsorb and retain the nonionic surfactant, and physically adsorbs the nonionic surfactant.
It does not swell due to this. The oil absorption amount of the oil absorbing carrier used in the present invention is larger than that of the above clay mineral. As a preferable oil-absorbing carrier, JIS-K6220
