The present invention relates to a cellulose-containing resin composition and a method of producing the same. The cellulose-containing resin composition includes cellulose nanocrystals containing, as cellulose, hemicellulose in an amount of 10 wt. % or less, and thereby the amount of VOCs released due to the cellulose can be reduced without using an additive, and a cellulose-containing resin composition having a lower TVOC amount than that of the resin itself can be provided.

Cellulose nanocrystal-containing resin composition

A gas-barrier composition including nanocellulose containing at least one of a sulfuric acid group, a sulfo group, or a phosphoric acid group; and a reactive crosslinking agent.

Gas-barrier composition

Nanocellulose containing a sulfuric acid group and/or a sulfo group, each of which is derived from a sulfuric acid treatment, and an anionic functional group derived from a hydrophilization treatment. The total amount of the sulfuric acid group and/or the sulfo group and the anionic functional group is more than 0.1 mmol/g and not more than 4.0 mmol/g. Also disclosed is a product including a mixture containing the nanocellulose and a method for producing the nanocellulose.
