Title ALCOHOL COMPOSITION
Abstract Provided is an alcohol composition comprising a C1-4 lower alcohol, water, a C12-20 aliphatic higher alcohol, and a surfactant other than the aliphatic higher alcohol. The content of the lower alcohol is 20 vol% or more.
Outline of related art and contending technology BACKGROUND ART
Alcohol disinfectant compositions containing lower alcohols such as ethanol are mainly used in the medical field or the like for the purpose of disinfecting the fingers. Typical usage modes thereof include a mode in which a liquid solution is sprayed from a spray container; a mode in which a gel agent is discharged from a pump container; a mode in which the liquid solution is discharged in foam form (foam form) using a pump container; and the like.
Among these usage modes, the mode in which the liquid solution is sprayed from the spray container causes dripping when sprayed onto the fingers, easily contaminating the floor and the like, and may scatter and enter the eyes and mouth. Furthermore, in an aspect in which the gel agent is discharged from the pump container, the gel agent solidifies and the nozzle part becomes clogged, or the gel agent partially solidifies at the tip of the nozzle part, and the discharge direction deviates from the predetermined direction. In contrast, in an aspect in which the solution is discharged from the pump container in the form of foam, dripping is unlikely to occur when the solution is discharged to the fingers, and the foam-like disinfectant can remain in the entire fingers for a long period of time, thus achieving excellent usability.
Here, since lower alcohols such as ethanol have an antifoaming effect, it is generally difficult to foam the alcohol disinfectant composition and to stably maintain the formed foam. In view of such problems, various alcohol disinfectant compositions have been proposed to date.
For example, Patent Document 1 discloses a foam-type high concentration alcohol preparation containing a high concentration of alcohol. Patent Document 1 describes blending a fluorine-based anionic surfactant and a cationic compound in order to foam a liquid and stably maintain the formed foam.
Patent Document 2 discloses a foamable alcohol composition that contains alcohol in a high concentration and foams by being mixed with air at a low pressure. Patent Document 2 describes blending a specific silicone-based surfactant in order to foam the liquid.
