Description

BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

The present invention relates to a granular or powdery detergent composition containing a non-ionic surface active agent. More particularly, the invention relates to a granular or powdery detergent composition comprising a non-ionic surface active agent adsorbed on a water-insoluble adsorption member. More specifically, the present invention relates to a granular or powdery detergent composition having a good flowability, which comprises an amorphous, phosphorus-containing alkali metal aluminosilicate on which a non-ionic surface active agent is adsorbed. By the term "good flow-ability" used herein is meant such a property that the granular or powdery detergent composition keeps a dry non-sticky state for a long time and cohesion or caking is not caused.

2. DESCRIPTION OF PRIOR ARTS

Most non-ionic surface active agents suitable for detergents are in the form of liquids or viscous solids at normal temperatures, and they can hardly be incorporated in granular or powdery detergent compositions as they are. As the method for incorporation of such non-ionic surface active agent in a detergent, there can be mentioned (1) a method in which a non-ionic surface agent is incorporated in a slurry of a detergent and the mixture is spray-dried, (2) a method in which a non-ionic surface active agent is adsorbed on a specific substance and the adsorption mixture is incorporated into a powdery detergent, and (3) a method in which a detergent base free of a non-ionic surface active agent is formed by spray drying and a non-ionic surface active agent is sprayed onto the detergent base to cause it to adhere to the detergent base.

According to the spray-drying method (1), however, a part of the non-ionic surface active agent is lost by contact with hot air in the drying column and is discharged with the exhaust gas, and therefore, generation of a bad smell or environmental pollution is caused. According to the spray-adhering method (3), the surface active agent can be included only in a small amount such as several percent. Therefore, at the present, there is mainly adopted a method in which a liquid or viscous solid non-ionic surface active agent is adsorbed on a specific substance to form a powdery detergent composition having a good flowability. As this specific substance (adsorbent), there are known finely divided inorganic substances such as talc, finely divided silica, clay and calcium silicate. However, these inorganic substance powders have, in general, no particular property other than the property of adsorbing a non-ionic surface active agent and providing a powder having a good flowability, and they have no positive effect of improving the washing capacity. Further, such inorganic powder should be incorporated in a large quantity in order for the non-ionic surface active agent to exert a sufficient washing power, and therefore, such inorganic powder fails to satisfy industrial requirements sufficiently. It has been attempted to adsorb a non-ionic surface active agent on builders customarily incorporated into powdery detergents, such as sodium tripolyphosphate, sodium perborate, sodium sulfate, sodium carbonate and the like. Also in this case, if the amount of the non-ionic surface active agent exceeds 10% by weight, cohesion or caking is readily caused and a composition having a sufficient flowability cannot be obtained. Recently, there has been proposed a process (see Japanese Patent Application Laid-Open Specification No. 119813/75) in which a non-ionic surface active agent is adsorbed on a alkali metal or alkaline earth metal aluminosilicate recently proposed as a water-insoluble builder (see Japanese Patent Application Laid-Open Specifications Nos. 12381/75, 21009/75, 53404/75 and 37104/75 and West Germany Patent Application Laid-Open Specification No. 2,538,679), and the mixture is then granulated and incorporated in a detergent. As a result of our researches, it has been found that even if non-ionic surface active agents are adsorbed on these aluminosilicates, it is difficult to obtain powders having a good flowability. Under such background, it has been eagerly desired to develop a non-ionic surface active agent adsobent which is capable of adsorbing a non-ionic surface active agent at a high concentration and keeping a good flowability, and having a washing effect at the same time.

SUMMARY OF THE INVENTION

As a result of our researches made with a view to developing such non-ionic surface active agent adsorbent, it was found that a specific adsorbent can adsorb a non-ionic surface active agent at a high concentration while keeping a good flowability and it has a high divalent metal ion-sequestering property and a high washing effect. Based on this finding, we have now completed the present invention.

More specifically, in accordance with the present invention, there is provided granular or powdery detergent composition comprising a non-ionic surface active agent adsorption mixture composed of a non-ionic surface active agent adsorbed on a water-insoluble, amorphous, phosphorus-containing alkali metal aluminosilicate represented by the following general formula (I):

X(M.sub.2 O).Al.sub.2 O.sub.3.Y(SiO.sub.2).Z(P.sub.2 O.sub.5)..omega.(H.sub.2 O) (I) wherein M stands for Na or K, and X, Y, Z and .omega. are mole numbers of the respective components satisfying the following requirements: 0.20.ltoreq.X.ltoreq.1.10, 0.20.ltoreq.Y.ltoreq.4.00, and 0.001.ltoreq.Z.ltoreq.0.80, preferably 0.01.ltoreq.Z.ltoreq.0.55, .omega. being an optional positive number inclusive of 0.

It is construed that the amorphous, phosphorus-containing alkali metal aluminosilicate of the above general formula (I), that is used in the present invention, has a structure in which a part of [SiO.sub.4 ] of the aluminosilicate is replaced by [PO.sub.4 ], and that introduction of [PO.sub.4 ] has some influence on the surface of the solid and exerts an effect of improving the non-ionic surface active agent-adsorbing property and divalent metal ion-sequestering property, although the mechanism has not yet been elucidated. The amorphous, phosphorus-containing alkali metal alumino-silicate of the present invention can be prepared, for example, by simultaneously adding an aqueous solution of an alkali metal silicate and an aqueous solution of an alkali metal phosphate to an aqueous solution of aluminum sulfate, agitating the mixture sufficiently, adding sodium hydroxide to the mixture and agitating the mixture at 90.degree. to 100.degree. C. for about 1.5 hours. The amorphous, phosphorus-containing alkali metal aluminosilicate is industrially advantageous also in the point that it can easily be synthesized according to a method as described above. It is preferred that each of the calcium ion-sequestering and magnesium ion-separating capacities of the amorphous, phosphorus-containing alkali metal aluminosilicate of the present invention represented by the general formula (I) be at least 100 mg, especially at least 150 mg, calculated as CaCO.sub.3, per gram of the aluminosilicate. It also is preferred that the particle size of the aluminosilicate of the present invention be smaller than 100.mu., particularly smaller than 50.mu., especially particularly less than 10.mu..

EXAMPLE 4

Oxocohole 7EO [C.sub.12-13 --O--CH.sub.2 CH.sub.2 O).sub.7 H manufactured by Nissan Kagaku] was adsorbed in an amount of 50% by weight on P-1 of the present invention and the resulting adsorption mixture was homogeneously incorporated in an amount of 5 to 30% by weight into an ordinary powdery detergent formed by spray drying. The flowability and other properties of the resulting detergent composition were tested to obtain results shown in Table 3.

(1) Measurement Method:

The flowability was determined by using an apparent density measuring tester according to the synthetic detergent method JIS K-3362. More specifically, about 100 cc of the powdery detergent was permitted to freely fall down into a 100-cc beaker located on the lower end from a density measuring tester and the quantity of the detergent was precisely measured. Then, the measured detergent was charged in a funnel portion of the apparent density measuring tester and a damper on the lower end of the tester was opened. The time required for all the detergent powder to fall down was measured, and the flowability was evaluated based on this time. A shorter time indicates a better flowability.

The breaking load was measured in the following manner. Namely, 1.5 g of the powdery detergent was charged in a cylindrical cylinder having a diameter 1.5 cm, and an iron plate having a weight of 100 g was placed thereon and the detergent was compressed for 3 minutes to form a tablet. Then, iron plates, each having a weight of 10 g, were gradually placed on the tablet at intervals of 30 seconds. When the tablet was broken, the number of the iron plates were counted. This test was conducted three times and an average value was calculated. The breaking load is expressed in terms of grams of the iron plates. A higher breaking load indicates a higher stickiness.

The caking property was determined in the following manner. Namely, 12.5 g of the sample was charged in a box formed of filter paper [7.4 cm .times. 4.4 cm .times. 2.8 cm (height)], and the surface of the sample was levelled and an iron plate of a size of 7.2 cm .times. 4.2 cm was placed on the sample. The sample was allowed to stand for 7 days in a thermostat chamber maintained at a temperature of 30.degree. C. and a relative humidity of 80%. Then, the detergent powder was placed on a sieve of a mesh size of 4 mm .times. 4 mm. The weight A (g) of the powder left on the sieve and the weight B (g) passing through the sieve were measured and the passage ratio was calculated according to the formula: ##EQU2##

A higher value indicates a reduced tendency to cake.

From the results shown in Table 3, it will readily be understood that even when the non-ionic surface active agent adsorption mixture of the present invention is incorporated in a powdery detergent, the detergent retains a good flowability and the adsorption mixture has no bad influence on detergents and other powdery materials.
