Abstract
An absorbent adapted to be used in a spray can charged with a liquefied gas, which exhibits excellent absorbing performance and excellent liquid retention. The absorbent is composed of an assembly of pulverized cellulose fibers that includes at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less. The absorbent is formed into a sheet-shaped or a columnar configuration, or a surface sheet is laminated on a surface of the absorbent. The absorbent composed of 70 through 90 mass % of cellulose fibers that include 45 mass % or more of fine cellulose fibers having a fiber length of 0.35 mm or less, and 5 through 30 mass % of a fusion-bondable resin exhibits good formability.
