Abstract

A high-quality spray product that uses a less expensive propellant exhibiting a lower ozone-depleting potential and a lower global warming potential without using any fluorocarbon, any alternative thereto, etc., and exhibits an improved safety and an improved liquid retention. A dust blower as the spray product uses a propellant composed of a mixture of dimethyl ether and carbon dioxide, and an absorbent adapted to retain the propellant, which is composed of an assembly of pulverized cellulose fibers such that the cellulose fibers include at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less. The propellant and the absorbent are charged in a spray can having a spray nozzle, thereby preparing a dust blower.

Claims (9)

1 . A spray product produced by charging at least a propellant and an absorbent for retaining the propellant in a spray can having a spray nozzle, characterized in that the propellant is composed of a mixture of dimethyl ether and carbon dioxide, and

the absorbent for retaining the propellant 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.

2 . A spray product as claimed in claim 1 , wherein said propellant is composed of a liquefied mixture gas of dimethyl ether and carbon dioxide, and the weight ratio of carbon dioxide ranges from 0.1 to 30 weight %.

3 . A spray product as claimed in claim 1 , wherein said propellant is composed of a liquefied mixture gas of dimethyl ether and carbon dioxide, and the weight ratio of carbon dioxide ranges from 2 to 30 weight %.

4 . A spray product as claimed in claim 1 , wherein said absorbent is formed into a columnar configuration.

5 . A spray product as claimed in claim 1 , wherein said absorbent is formed into a sheet-shaped configuration.

6 . A spray product as claimed in claim 1 , wherein said absorbent is composed of cellulose fibers including at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less, and a fusion-bondable resin.

7 . A spray product as claimed in claim 6 , wherein said absorbent is composed of 70 through 95 mass % of cellulose fibers and 5 through 30 mass % of a fusion-bondable resin.

8 . A spray product as claimed in claim 1 , wherein said spray product is used as a dust blower.
