Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a softener composition. In particular, the present invention relates to a solid soft finish composition having excellent dispersion stability in water.

2. Description of the Related Art At present, as a softening agent, a liquid type in which a cationic softening agent is blended in an amount of 3 to 20% by weight is mainly used, but a method of using a softening agent as a powder type as a means for further concentrating is used. Some have been reported. Examples of these powder type softeners include, for example, JP-A-59-8
No. 800 discloses a method in which a cationic softening agent powder having an average primary particle diameter of 150 μm or less and silica fine powder are mixed and granulated using a nonionic surfactant as a binder. Certainly, the finer the particle size of the cationic softening agent powder, the higher the efficiency of adsorbing on generally treated clothes and the like, and therefore, it is necessary to finely disperse the powder. However, the use of the cation particles produced by this method has a drawback that the cation powder cannot be finely dispersed below the primary particles in water. In addition, the cationic softening agent is added in advance to 150
There is also a disadvantage that the production cost increases because the thickness is set to be less than μm, and it is not economical. JP-A-59-106575 discloses a method of incorporating a softening agent into synthetic silicic acid. However, in the softening particles produced by this method, when the cation is a dialkyl quaternary ammonium salt substantially insoluble in water, the cations trapped in the voids of the silicic acid particles are not released into water, so that the softening agent is used as a softening agent. Function cannot be exhibited. In addition, the synthetic silica has a small particle size (usually several microns or less), and the powder softener obtained by this method is in the form of fine powder. Not only is the property poor, but also the appearance as a product is not preferable.

EXAMPLES Hereinafter, the present invention will be described specifically with reference to examples and comparative examples, but the present invention is not limited to these examples. Example 1 (1) Preparation of Solid Soft Finishing Agent As the component (A), an amine compound represented by the general formula (I-2) quaternized with methyl chloride was used at 45% by weight, and the component (B) was used. Using urea at 40% by weight as component (A), component (A) and component (B) were melt-mixed and then pulverized to powder. Then, 10% by weight of Cellzyme 2400T was mixed as a powder as the component (C) to obtain a solid soft finish composition. The balance is moisture. (2) Softening treatment A commercially available cotton towel is used as cotton, and an acrylic cloth is used as chemical fiber, and a commercially available laundry detergent “HITOP” (manufactured by Lion Corporation) is used at 50 ° C. using a reversing washing machine. 2
After repeated washing, it was thoroughly rinsed with ordinary-temperature tap water and used as a test cloth. First, after washing with “high top” using tap water at 25 ° C. and rinsing once, a softener composition is added to 30 liters of tap water at 25 ° C. so that the softening agent composition becomes 1 g as a softening base and uniform. Each test cloth was immersed in a solution having a bath ratio of 30 times and the ratio of the cotton towel to the acrylic cloth was set to 7/3, and treated for 1 hour. Next, it was dehydrated for 2 minutes. After the cloth thus treated was air-dried, the cloth was allowed to stand at 25 ° C. and 65% RH for 24 hours and used for an evaluation test. (3) Evaluation of Flexibility Using a 15% aqueous dispersion of di-hardened tallow alkyldimethylammonium chloride, a paired comparison was carried out using the treated cloth as a control by the above-mentioned softening treatment method, and evaluated according to the following criteria. +2: A texture that is more preferable than the control +1: A slightly more preferable texture than the control 0: Same as the control -1: A slightly more preferable texture of the control -2: A texture that is more preferable for the control The present invention Was excellent in dispersibility in water. Examples 2 to 11 and Comparative Examples 1 to 5 The same procedure as in Example 1 was repeated using the components (A), (B) and (C) shown in Table 1. Table 1 shows the obtained results.
