Abstract

A dehumidifying composition according to an embodiment of the present invention includes oil and a surfactant, wherein the oil and the surfactant may be mixed by at least one of mechanical stirring, ultrasonic stirring, ultrasonic grinding, or magnetic stirring.

First claim

1 . A dehumidifying composition containing oil and a surfactant.

2 . The dehumidifying composition of claim 1 , wherein the dehumidifying composition has a form with the surfactant dispersed in the liquid oil.

3 . The dehumidifying composition of claim 1 , wherein the oil and the surfactant are mixed with each other via at least one of mechanical stirring, ultrasonic stirring, ultrasonic grinding, and magnetic stirring.

4 . The dehumidifying composition of claim 1 , wherein the surfactant surrounds and traps moisture introduced from the outside to create droplets of the moisture within the oil,
wherein an emulsion where the moisture trapped by the surfactant spreads throughout the oil is formed.

5 . The dehumidifying composition of claim 1 , wherein the oil includes at least one of mineral oil, synthetic oil, silicone oil, and vegetable oil,
wherein the mineral oil includes at least one of Paraffinic oil, Naphenic oil, and Aromatic oil, wherein the synthetic oil includes at least one of polyalphaolefin, polyglycol, and synthetic ester oil, wherein the vegetable oil includes at least one of soybean oil, sunflower oil, grape seed oil, coconut oil, and olive oil, wherein the surfactant includes at least one of an anionic surfactant, a cationic surfactant, an amphoteric ion surfactant, and a non-ionic surfactant, wherein the anionic surfactant includes at least one of alkylbenzene sulfonate, ammonium lauryl sulfate, chlorosulfolipid, docusate, perfluorobutanesulfonic acid, potassium lauryl sulfate, soap, sodium alkyl sulfate, sodium dodecyl sulfate, sodium laurate, sodium laureth sulfate, sodium nonanoyl oxybenzene sulfonate, and sulfolipid, wherein the cationic surfactant includes at least one of behentrimonium chloride, benzalkonium chloride, benzododecinium bromide, cetalkonium chloride, cetrimonium bromide, cetylpyridinium chloride, dimethyldioctadecylammonium bromide, dimethyldioctadecylammonium chloride domiphen bromide, octenidine dihydrochloride, olaflur, pahutoxin, and stearalkonium chloride, wherein the amphoteric ion surfactant includes at least one of lauryl betaine, sodium hydroxymethylglycinate, RENNIN, and cocamidopropyl betaine, wherein the non-ionic surfactant includes at least one of alkyl polyglycoside, cetyl alcohol, glycerol monostearate, gum arabic, nonoxynol, oleyl alcohol, polysorbate, poly vinyl alcohol, sorbitan, sorbitan monolaurate, sorbitan monostearate, sorbitan monooleate (Span 80), Triton X-100, and Tween 80.

6 . The dehumidifying composition of claim 1 , wherein an added amount of the surfactant is determined within a range from 1.5 to 2.5 times a moisture capture amount.

7 . The dehumidifying composition of claim 1 , wherein a plurality of types of surfactants are mixed with the oil,
wherein the plurality of types of surfactants are sequentially added to and stirred in the oil in an ascending order of an addition concentration.

8 . The dehumidifying composition of claim 1 , wherein a first surfactant and a second surfactant of different types are mixed in the oil,
wherein, among the first surfactant and the second surfactant, one with a smaller addition concentration is added to the oil and then completely mixed with the oil, and then the other with a greater addition concentration among the first surfactant and the second surfactant is added to and mixed with the oil.

9 . The dehumidifying composition of claim 1 , wherein the surfactant is mixed with the oil in an added amount twice or more than a set moisture capture amount within a range satisfying a concentration from 4.8 wt % to 31.0 wt % with respect to the oil.

10 . A method for producing a dehumidifying composition, the method comprising:
producing of adding a surfactant to oil and stirring the surfactant.

11 . The method of claim 10 , wherein the producing includes mixing the surfactant with the oil in an added amount twice or more than a set moisture capture amount within a range satisfying a concentration from 4.8 wt % to 31.0 wt % with respect to the oil.

12 . The method of claim 10 , wherein the producing includes a first step and a second step,
wherein the first step includes adding a first surfactant with a small addition concentration among a plurality of types of surfactants to the oil and stirring the first surfactant, wherein the second step is performed when the addition and the stirring of the first surfactant with respect to the oil are completed, wherein the second step includes adding a second surfactant having a greater addition concentration than the first surfactant among the plurality of types of surfactants to the oil and stirring the second surfactant.

13 . A method for producing a dehumidifying composition, the method comprising:
adding 60 g of Tween 80 to each 400 g of silicone oil and stirring the Tween 80; and additionally adding 120 g of Span 80 to each 400 g of the silicone oil, stirring the Span 80, and performing ultrasonic grinding on the Span 80 when the stirring of the Tween 80 in the silicone oil is completed.
