JPH04316676A - Bactericidal deodorant finishing agent - Google Patents

Abstract

PURPOSE:To impart clothes, etc., with bactericidal deodorant effect by a simple process at home, etc. CONSTITUTION:Clothes are immersed in or sprayed with a solution containing 0.01-2.0wt.% of a quaternary ammonium salt to apply antibacterial deodorizing property to the clothes. As an alternative method, a solution containing 5-20wt.% of a quaternary ammonium salt is diluted 10-500 times with water and clothes are immersed in or sprayed with the diluted solution to obtain clothes having antibacterial deodorizing property.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finishing agent that imparts an antibacterial and deodorizing effect to clothing and the like by a simple operation at home.

0002

BACKGROUND OF THE INVENTION Fiber products made of natural or synthetic fibers are used as clothing such as underwear and socks.

0003

[Problems to be Solved by the Invention] However, when human sweat or food and drink adhere to these clothes, bacteria and mold grow, resulting in a foul odor that makes people feel uncomfortable.

0004

[Means for Solving the Problems] To solve these problems, dipping or spraying with a solution of a quaternary ammonium salt is simple and effective. Since this quaternary ammonium salt is a safe compound, it is quite possible to carry out this antibacterial treatment in daily laundry work at home. Salts, long-chain monoalkyldimethylbenzyl ammonium salts, and long-chain monoalkylpyridium salts may be used singly or in combination.

Among these quaternary ammonium salts, the long chain alkyl group of the long chain monoalkyltrimethylammonium salt is selected from the range of C8 to C20, particularly C10 to C1.
A range of 8 is desirable. The long chain alkyl group of the long chain dialkyldimethylbenzyl ammonium salt is selected from the range of C5 to C20, with the range of C8 to C20 being particularly preferred. The long chain alkyl group of the long chain monoalkyldimethylbenzylammonium salt is selected from the range of C8 to C20, especially C10 to
A range of C18 is desirable. The long chain alkyl group of the long chain monoalkylpyridium salt is selected from the range of C8 to C20,
In particular, a range of C10 to C18 is desirable. The solvent for the quaternary ammonium salt is preferably water or an aqueous solution of ethyl alcohol, isopropyl alcohol, propylene glycol, or the like.

[0006]

[Function] By immersing clothing in a 0.01 to 2.0% by weight solution of quaternary ammonium salt, dehydrating and drying, clothing having good antibacterial and deodorizing effects can be obtained. The same effect can also be obtained by spraying the same solution onto clothing and letting it dry. The quaternary ammonium salts remaining in clothing are gradually eluted into clothing by moisture such as sweat generated by the human body, producing an antibacterial effect.

Some of the quaternary ammonium salts used in the present invention have antistatic and softening effects, and it is also possible to prepare fabric softeners with antibacterial properties. Furthermore, if the concentration of the quaternary ammonium salt is less than 0.01% by weight, hardly any antibacterial and deodorizing effect can be expected, and if it is more than 2% by weight, problems of skin irritation will occur. Therefore, 0.1~
A range of 0.5% by weight is desirable. Note that the effects of long-chain monoalkyldimethylbenzylammonium salts and long-chain monoalkydpyridium salts may be reduced by ultraviolet rays in sunlight, so if drying outdoors, reduce the content or reduce the content. It is desirable to have a prescription that does not.

[0008]

[Example] A cotton cloth was soaked in a 0.5% solution each of cetyltrimethylammonium chloride, alkyldimethylbenzyl chloride, disterialdimethylammonium chloride and laurylmethylammonium chloride,
After dehydration, the cloth was air-dried and used as an antibacterial test cloth, and its effectiveness was tested using the following test bacteria. Staphylococcus
aureus IF012732

(Staphylococcus aureus)
hia coli IF
03301

(Escherichia coli) The test method is to inoculate the above test bacteria onto dissolved ordinary agar (the bacterial concentration is approximately 100,000
0 particles/ml) was poured into a petri dish with a diameter of 9 cm and solidified. The above antibacterial test cloth cut to a diameter of 2 cm was placed on this surface, incubated at 37° C. for 48 hours, and the diameter of the inhibition circle formed around the test cloth was measured (based on AATCC Test Method 90). The results are shown in Appendix Table 1.

Usage test: Socks that had been washed with household laundry detergent (control) and socks that had been washed in the same manner were immersed in the antibacterial agent solution of the example (cetyltrimethylammonium chloride 0.5%), dehydrated, and
Ten panelists (male) each wore the dry socks for one day on the left and right sides, and sensually evaluated the odor when they took them off. As a result, 0 people said it was worse than the control, 2 people said it was equal to the control, and 8 people said it was better than the control.

0010

[Effects of the Invention] The results of the above tests show that the antibacterial and deodorizing finishing agent of the present invention exhibits excellent antibacterial and deodorizing effects.

[Table 1] An antibacterial test was conducted using four types of antibacterial and deodorizing finishing agents of the present invention, and the diameters (unit: mm) of the inhibition circles formed are shown.

Claims (2)

[Claims] Claim 1: Quaternary ammonium salt 0.01-2.
An antibacterial and deodorizing finishing agent containing 0% by weight, which imparts antibacterial and deodorizing properties by dipping or spraying onto clothing. Claim 2: Containing 5 to 20% by weight of quaternary ammonium salt, diluted 10 to 500 times with water and soaked in clothing;
Or an antibacterial and deodorizing finishing agent that imparts antibacterial and deodorizing properties when sprayed.
