Document Type and Number:
WIPO Patent Application WO/2013/099861
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a technique for preventing the decrease in the content of dibutylhydroxytoluene in a preparation and improving the stability of dibutylhydroxytoluene.
In a container in which a dibutylhydroxytoluene-containing preparation is to be contained, a resin containing at least one polymer selected from the group consisting of polybutylene terephthalate, polyethylene terephthalate, polystyrene, acrylonitrile butadiene styrene, polycarbonate, polymethyl methacrylate and an ethylene-(vinyl alcohol) copolymer is used as a resin constituting the inner wall surface (a wall surface of an interior space in an expulsion section and/or a wall surface of a lid which faces an expulsion outlet of the expulsion section) of the container. It becomes possible to prevent the adsorption of dibutylhydroxytoluene onto the expulsion section and keep the content of dibutylhydroxytoluene in the preparation steadily.
