Description

  The present invention relates to an aerosol composition for preventing floating substances from adhering.

  Hay fever is an allergic disease that causes various symptoms such as sneezing, runny nose, headache, lacrimation, blurred vision and general malaise when pollen enters the body. At present, many people suffer from hay fever, which is a serious social problem.

  Various drugs and treatments for treating hay fever have been studied, but there is no better way to prevent allergen pollen from entering the body. Therefore, in order to prevent pollen from entering the body, many masks and glasses that do not allow pollen to pass through have been developed.

  However, for example, even when the pollen does not enter the body when going out, the pollen attached to the clothing or the like is brought indoors as it is. In many cases, pollen attached to clothing or the like floats indoors, and pollen develops or worsens when the pollen enters the body.

  Therefore, a method for processing a fiber structure has been developed so that pollen is less likely to adhere or can be easily dropped even if it adheres. However, in order to perform such processing, a dedicated machine or technology is required, and it is very difficult to perform such processing in a general household (for example, see Patent Document 1). Further, such a method is not preferable because it costs high.

Moreover, although the cleaning agent for aerosols which has the adhesion prevention effect of dirt and dust is proposed, this is for disks, such as CD and MD, and cannot be applied to textiles (for example, refer to patent documents 2).

Example 1
A stock solution of an aerosol composition was prepared by mixing 4000 parts by weight of ethanol and 10000 parts by weight of water with 100 parts by weight of silica powder having an average particle size of 8 to 12 nm. The stock solution and 5900 parts by weight of DME were filled into an aerosol container (atomizer) to obtain an aerosol composition.

Comparative Example 1
A stock solution of an aerosol composition was prepared by mixing 80 parts by weight of ethanol and 100 parts by weight of water with 100 parts by weight of silica powder having an average particle size of 8 to 12 nm. The stock solution and 120 parts by weight of DME were filled in an aerosol container (atomizer) to obtain an aerosol composition.

Test example 1
The aerosol composition obtained in Example 1 and Comparative Example 1 was sprayed uniformly on a 30 cm × 30 cm nylon (about 10 g) and dried for 2 hours. This test fabric was used in the following two tests.

(1) Pollen removal test After pollen (cedar) was attached to the above-mentioned test piece, pollen was removed by gently paying it by hand. The state before and after the hand was wiped in the same section was photographed with an electron microscope (FIG. 1), and the number of each pollen was counted. From these numbers, the pollen reduction rate was determined using the following formula.

Reduction rate (%) = [(number of pollen before removal−number of pollen after removal) / number of pollen before removal] × 100
The decrease rate of pollen of nylon (blank) to which nothing was sprayed was 21.5%, whereas the decrease rate of nylon pollen sprayed with the aerosol composition of Example 1 was 85.4%.

(2) Texture test
