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 is not sticky on the surface under high temperature and high humidity, and has excellent 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. Furthermore, 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 nonionic surfactant is manufactured, the surface of the tablet becomes sticky and it is difficult to handle. Further, when tablets are used as the detergent, there is a problem that solubility is deteriorated. To solve this problem of solubility, for example, JP-A-5-65
In JP-A-500, a specific inorganic salt is added. However, this technique is effective only at 20 ℃
It is a sweet condition at a relatively high water temperature, and in practice, the water temperature becomes 10 ° C. or lower during winter washing. 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 when it is simply made into a tablet, the strength as a tablet is insufficient, and there is a problem that it collapses during storage or transportation.

[0003]

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. That is the purpose.

[0004]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventor has found that a specific nonionic surfactant, a nonionic gelling agent for gelling the nonionic surfactant, and an oil absorbing carrier. It was found that the combined use of and can improve the stickiness of the tablet surface and the tablet strength under high temperature and high humidity. Furthermore, by adding a disintegration accelerator for disintegrating the tablet when the tablet is dissolved in water to the above-mentioned three components, the tablet can be treated at a low temperature of the tablet without impairing its good surface condition and strength. The inventors have found that the solubility in the solution can be significantly improved, and have completed the present invention. That is, the present invention provides (1) an alcohol type nonionic gelling agent or a fatty acid alkyl ester alkoxylate nonionic surfactant, (2) a nonionic gelling agent,
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 contained in the granular nonionic detergent composition in an amount of preferably 10 to 50% by weight, more preferably 10 to 40% by weight, and particularly preferably 10 to 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 nonionic gelling agent used in the present invention has a function of gelling a nonionic surfactant to solidify and retain the nonionic surfactant in the tablet detergent, and also has a three-dimensional structure due to gelation. Has the effect of improving the strength of. Therefore, various nonionic gelling agents can be used as long as the nonionic gelling agent has such a function.

The oil-absorptive carrier used in the present invention has the effect of improving the stickiness of the tablet surface due to exudation of nonion under high temperature and high humidity, and facilitating the handling of the tablet detergent. The oil-absorbing carrier is a finely divided powder that is sufficient to adsorb and retain the nonionic surfactant, physically adsorbs the nonionic surfactant, and does not swell due to this.

˜15% by weight, particularly preferably 1 to 10% by weight. If this amount is less than 0.1% by weight, exudation of the nonionic surfactant is remarkable under high temperature and high humidity of the obtained tablet, and the tablet surface becomes sticky easily. On the other hand, if it exceeds 30% by weight, it becomes difficult to mold tablets, which is also not preferable.
