Document Type and Number:
WIPO Patent Application WO/2019/078232
Kind Code:
A1
Abstract:
A carbon dioxide sustained release pack for skin applications according to the present invention is a bag-shaped carbon dioxide sustained release pack for sustainably releasing carbon dioxide enclosed therein so that the carbon dioxide can come into contact with the skin, and is configured into a bag-like shape by means of at least a resin sheet (A), wherein the resin sheet (A) satisfies at least the following requirements (A-1) and (A-2): (A-1) the carbon dioxide permeability is 20 L/(m2·day·atm) or more as measured in accordance with JIS K7126-1 under the conditions of a temperature of 23°C and a relative humidity of 0%; and (A-2) the Oken air permeability is less than 5 μm/(Pa·s) as measured in accordance with JIS P8117:2009 at 23°C.
