Abstract
Official abstract text for this publication.
An object is to provide a foamable aerosol composition that can be continuously ejected from the container to form dense and uniform foam, and that the formed foam has certain elasticity as well as can be easily spread on an object, and the foamable aerosol composition comprises a stock solution including cellulose nanofibers and a propellant is provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition, comprising: a stock solution comprising a carboxymethylated cellulose nanofiber, a surfactant, and a fatty acid soap; and a propellant comprising liquefied natural gas, wherein a content ratio of the carboxymethylated cellulose nanofiber is from 0.001 to 0.05% by mass, and a content ratio of the fatty acid soap is from 1% by mass to 10% by mass, relative to a total amount of the stock solution, a content ratio of the propellant is from 1% by mass to 60% by mass, and a content ratio of the stock solution is from 40% by mass to 99% by mass, relative to a total amount of the composition, the fatty acid soap comprises stearic acid and behenic acid, and the composition is in the form of a foamable aerosol. 2. The composition according to claim 1 , wherein the stock solution further comprises an oxidized cellulose nanofiber, and an amount of a carboxy group contained in the oxidized cellulose nanofiber is from 0.1 mmol/g to 3.0 mmol/g relative to a bone-dry mass of the oxidized cellulose nanofiber. 3. The composition according to claim 1 , wherein a degree of substitution with carboxymethyl group per glucose unit in the carboxymethylated cellulose nanofiber is from 0.01 to 0.50. 4. The composition according to claim 1 , wherein the foamable aerosol composition is a facial treatment mask. 5. A kit, comprising: an aerosol container; and the composition according to claim 1 filled in the aerosol container. 6. The composition according to claim 1 , wherein an amount of the surfactant is from 0.05 to 10% by mass relative to the total amount of the stock solution. 7. The composition according to claim 1 , wherein the stock solution is foamed and is not in a liquid form when ejected with the propellant. 8. The composition according to claim 1 , wherein the content ratio of the carboxymethylated cellulose nanofiber is from 0.005 to 0.01% by mass, relative to the total amount of the stock solution. 9. The composition according to claim 1 , wherein the content ratio of the carboxymethylated cellulose nanofiber is 0.005% by mass, relative to the total amount of the stock solution.
