Description

  The present invention relates to a mask treatment composition for enhancing protection against airborne particles, and a mask treatment spray for enhancing protection against airborne particles obtained by filling the composition with a spray container. . The present invention also relates to a method for treating a mask for enhancing protection against airborne particles, characterized by using the composition or the spray.

  It is said that the proportion of Japanese people suffering from so-called hay fever by cedar pollen is about 10-15% of the population, and hay fever is now considered to be a modern disease in the Japanese. . Hay fever develops unpleasant symptoms such as itchy eyes and nasal congestion that cannot be confirmed without suffering from this. In addition, allergic symptoms to house dust such as mite carcasses, feces and mold spores are also regarded as a major problem today.

  As one of the countermeasures against such hay fever and allergic symptoms to house dust, it is known that the use of a mask is effective, and the entry of airborne particles such as pollen, house dust, dust, and viruses into the nostril Various masks with countermeasures for effectively suppressing the above have been disclosed so far. For example, fine carbon charcoal is put in a sachet made of Japanese paper and attached to a mask (see, for example, Patent Document 1), or a fibrous superabsorbent polymer is used for fibers constituting the mask. By using a fiber that has a functional group having a positively charged functional group that adsorbs suspended matter by keeping it moist and prevents entry into the nostril (see, for example, Patent Document 2), or a fiber having a chemically positively charged functional group. Those that adsorb pollen and prevent entry into the nostril are known (for example, see Patent Document 3).

  However, the former, in which a sachet is attached to the mask, has a problem in that it is not excellent in usability, such as an increase in the thickness of the mask, obstructing air permeability, and loss of fit. Further, since the latter two are characterized by the fibers themselves constituting the mask, they have to have unique fibers at the time of manufacturing the mask. All of them impart a function of enhancing the protection against airborne particles at the time of manufacturing the mask, and the protection of the mask already on hand cannot be easily improved later.

Example 1 Preparation of various mask treatment compositions Aqueous solutions containing coconut oil fatty acid diethanolamide (nonionic surfactant) at 0.5 wt%, 1.0 wt%, 3.0 wt% and 5.0 wt% Were prepared to obtain a mask treatment composition. Similarly, polyoxyalkylene alkyl ether (nonionic surfactant), sucrose fatty acid ester (nonionic surfactant), polyoxyethylene sorbitan fatty acid ester (nonionic surfactant), glycerin (polyhydric alcohol), sorbitol For (polyhydric alcohol), aqueous solutions of various concentrations were prepared, and various mask processing compositions were obtained.

Test Example 1 Pollen Permeation Suppression Effect Test The pollen permeation suppression effect of the various mask processing compositions obtained in Example 1 was tested as follows using a commercially available disposable mask. The results are shown in Table 1.

[Pollen permeation suppression test]
Each of the commercially available disposable masks 20 × 20 cm was uniformly coated with 0.3 mL of various mask processing compositions and dried. As a control, a mask coated with only water and dried was similarly prepared. The processed mask was attached to the holder of the suction filtration apparatus as shown in FIG. 1, and 0.1 g of cedar pollen was evenly spread over the entire mask from above. At a flow rate of 10 L / min, suction was performed from below the mask for 3 minutes, and the weight of the mask after suction was measured. The pollen permeation | transmission suppression rate of each composition for mask processing was calculated | required by the following formula.
Pollen permeation inhibition rate (%) = (C−A) / B × 100
(A: weight of mask, B: weight of cedar pollen scattered on the mask, C: weight of mask after suction)

  As shown in Table 1, the mask treated with various mask treatment compositions containing a nonionic surfactant or a polyhydric alcohol suppresses pollen permeation more than a mask treated with water alone. It has been clarified that the permeation suppression rate tends to increase depending on the concentration of nonionic surfactant or polyhydric alcohol.

  The composition for mask treatment of the present invention can be suitably used for enhancing the protection of the mask against airborne particles. Therefore, the composition for mask treatment of the present invention can be used as, for example, a mask treatment agent for improving protection against pollen, a mask treatment agent for improving protection against house dust, and the like. Moreover, the composition for mask treatment of this invention can be used as a spray product for improving the protection against airborne particles by filling a spray container.

FIG. 1 is a schematic view of a suction filtration device used in a pollen permeation suppression effect test.
