Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fabric softener composition that imparts flexibility to clothing.

Moxa Moxibustion 1 Di-long-chain alkyl quaternary ammonium salts have an excellent softening effect on fibers of clothing and the like, and are used as softening agents during or after washing. Liquid products are the mainstream for softening agents in order to improve their dispersion in water, but their concentration is limited to around 5% due to liquid physical properties, and further concentration is desired. To achieve concentration, there is a method of using a liquid form as a softening agent, but it is preferable to use it in the form of granules from the viewpoint of prevention of dust generation and ease of use. In this granulation method, di-long chain quaternary ammonium salt and silica are mixed, and a portion of the mixture is granulated using a nonionic surfactant.

Furthermore, it has been reported that zeolite is added to make granules (Japanese Patent Application Laid-open No. 8800/1983). However, according to this method, the aggregation and coalescence of granulated particles during storage are prevented. Although it can be prevented, when dissolved in a large amount of water, the particles tend to aggregate and coalesce, resulting in poor solubility.

An object of the present invention is to provide a granular flexible composition with excellent dispersion and solubility in an aqueous solution, and a method for producing the same.

The granular flexible composition of the Migotachi Naoki of the present invention comprises the following (A) and (
B) The component is granulated.

(A) Foaming composition consisting of acidic substance powder and alkaline carbonate powder that are solid at room temperature: 30 to 80% by weight and (B) dilong chain alkyl quaternary ammonium salt powder with an average-order diameter of 150 μm or less Body: 10-50% by weight.

The present invention will be explained in more detail below.

The foamable composition of component (A) consists of an acidic substance that is solid at room temperature and an alkaline carbonate. Once the effervescent composition is dissolved in water. The acidic substance and the alkaline carbonate react to generate carbon dioxide gas, and due to this foaming power, the granular softener composition collapses and the di-long chain alkyl quaternary ammonium salt powder is rapidly dispersed in water.5. Dissolution speed can be achieved.

The foamable composition of component (A) has a content of 30 to 30% in the softener composition.
It is blended in an amount of 80%, preferably 50 to 70%.

In order to easily disintegrate the granules in water, 30% by weight or more
- It is necessary to blend. On the other hand, if it exceeds 80% by weight, not only will it be difficult to form granules, but the blending range of the quaternary ammonium salt will be reduced. From the viewpoint of efficient foaming in an aqueous solution, the weight ratio (a)/(b) = 5/l~! /10°, preferably in the range of 371 to 115.

Examples of acidic substances include inorganic substances such as hydrometallic sulfites and aluminum salts of strong acids, and organic acids such as citric acid and succinic acid.

As the alkaline carbonate, a substance that decomposes and releases carbon dioxide gas by reaction with an acidic substance is used, and the "carbonate" in the present invention includes percarbonate.

Also included are bicarbonates (hydrogen carbonates). Specific examples of the salt include sodium helium salt, potassium salt, and the like.

As the di-long chain alkyl quaternary ammonium salt of component (B), a powder having an average dimensional diameter of 150 μm or less is used.

If the average dimensional diameter exceeds 150 um, even if it is separated into primary particles in water, it will not be possible to obtain a one-minute flexibility imparting effect.

Component CB) is blended in the softener composition in an amount of 10 to 50% by weight, preferably 15 to 30% by weight. If this amount is less than 10% by weight, concentration will be insufficient, while if it exceeds 50% by weight, it will be difficult to disintegrate the granules in water and decompose the quaternary ammonium salt into primary particles.

Representative examples of di-long-chain alkyl quaternary ammonium salts used in the present invention include the following.

(In the formula, R1, R,, Rff, R4, and X are as follows. R1-R2: Czx to C0 alkyl group R,, R
4: C, ~C4 alkyl group, benzyl group, 02~C
Hydroxyalkyl group or polyoxyalkylene group X of 4: halogen, CH35O,, C)I, SO9
or CHr(〉zu○□) Specific examples of the di-long chain alkyl quaternary ammonium salt represented by the above general formula CI) include (1) distearyldimethylammonium salt (2) dihydrogenated beef tallow alkyldimethylammonium salt ( 3) Dihydrogenated beef tallow alkylmethylbenzylammonium salt (4) Distearylmethylbenzylammonium salt (5) Distearylmethylhydroxyethylammonium salt (6) Distearylmethylhydroxypropylammonium salt (7) Distearyldihydroxyethylammonium salt For example, counter ions include chloride and bromide.

Moreover, it is preferable that the softener composition of the present invention further contains a water-insoluble fine powder. This water-insoluble fine powder is blended into the granules to prevent the primary particles of the quaternary ammonium salt from agglomerating, and on the other hand, it is mixed with the granules to prevent the granules from agglomerating together. The water-insoluble fine powder preferably has an average primary particle size of 10 μm or less, and specific examples thereof include zeolite, silica, calcium carbonate, and calcium stearate. Note that the water-insoluble fine powder of the present invention includes those that are poorly water-soluble. The water-insoluble fine powder is blended in the granular softener composition of the present invention in an amount of 0 to 10% by weight.
It is blended in a range of 10% by weight.

Preferably, the granular softener composition contains substantially no water. If water is present, acid/alkali reactions occur within the granules during storage.

Lack of stability 6 The softener composition of the present invention is granulated into granules, preferably having an average particle size of 200 to 2000 μm, more preferably 300 to 1000 μm, rru.

Granulation may be carried out by any suitable means, but since the use of water is unfavorable as mentioned above, it is desirable to use a non-aqueous thickening agent as the binder. As the non-aqueous thickening agent, nonionic surfactants, polyethylene glycol, liquid paraffin, etc. are used. Examples of nonionic surfactants include polyoxyethylene alkyl ether (carbon number of alkyl group: 10 to 24) or polyoxyethylene alkyl phenyl ether (carbon number of alkyl group: 6), in which the average number of added moles of ethylene oxide is 7 or less. ~18
) is preferred. Furthermore, polyethylene glycol having a molecular weight of 1000 or less is suitable. The non-aqueous thickening agent is blended in the granular soft cutting material in an amount of 5 to 30% by weight, preferably 10 to 25% by weight. In order to stably form granules, 5% by weight or more is required; on the other hand, if it exceeds 30% by weight, the tackiness becomes high and the granules agglomerate, which is not preferable.

The granular flexible composition of the present invention is produced by uniformly mixing the following components (A-1), (A-2), and (B), and granulating the composition using component (C) as a binder. It can be manufactured by Here, the usage of each component is as already explained.

(A-1): Acidic substance powder that is solid at room temperature, (A-2)
: Alkaline carbonate powder, (B): Average primary particle size 150
Di-long chain alkyl quaternary ammonium salt with a diameter of less than μm.

(C): Non-aqueous thickener Specific granulation methods include: (i) Extrusion granulation method in which raw materials are uniformly mixed and kneaded and granulated using an extrusion granulator; (n) Uniform A transfer granulation method in which a binder is sprayed onto the powder raw materials mixed with the powder, and the mixture is granulated using a dish-type granulator, five-rolling drum-type granulator, etc.

(iii) A crushing granulation method in which pellets formed by extrusion granulation or the like are crushed with a crusher and granulated.

etc. can be used.

It is also desirable to add water-insoluble fine powder during or after granulation to prevent aggregation of quaternary ammonium particles or granules.

3. Bad U.S. 1. In the granular softener composition of the present invention, the acidic substance in the granules reacts with the alkaline carbonate in water, generating carbon dioxide gas, and the granules quickly disintegrate. Moreover, this foaming force prevents the primary particles of the quaternary ammonium salt powder constituting the granules from agglomerating and coalescing, and quickly disperses them into the aqueous solution. Moreover, since the quaternary ammonium salt dispersed as -water particles has a small particle size and a large surface area, more microscopic dispersion and dissolution are possible.
