A process for preparing a consumer product including a chemically modified polysaccharide, where the process includes the steps of combining a slurry including polysaccharide with a reactant to form a polysaccharide-reactant mixture, where the reactant includes an ester group; combining a base with the polysaccharide-reactant mixture to form a polysaccharide-reactant-base mixture; and allowing the polysaccharide-reactant-base mixture to form a transesterified polysaccharide mixture, where the transesterified polysaccharide mixture includes an alcohol.

There is provided a method for producing hypromellose phthalate (HPMCP), the method not requiring any special device, and facilitating removal of impurities. More specifically, there is provided a method for producing HPMCP, including an esterification step of esterifying hypromellose with a carboxybenzoylating agent in the presence of an aliphatic carboxylic acid to obtain a reaction product solution containing HPMCP; a precipitation step of precipitating the HPMCP by mixing the reaction product solution with water to obtain a suspension of the precipitated HPMCP; a neutralization step of neutralizing the suspension with a basic substance to obtain a neutralized suspension; and a washing step of washing the HPMCP contained in the neutralized suspension to obtain the washed HPMCP.

A rubber composition contains: at least one rubber component selected from the group consisting of an ethylene propylene diene rubber, a chloroprene rubber, a nitrile rubber, and an acrylic rubber; 1.5 to 30 parts by mass of a fluorene-modified cellulose nanofiber per 100 parts by mass of the rubber component; and 30 to 120 parts by mass of a carbon-based filler per 100 parts by mass of the rubber component. A method of producing a rubber composition comprises: kneading a dispersion of a fluorene-modified cellulose nanofiber in a process oil and a rubber component to prepare a kneaded material; and mixing a vulcanizing agent into the kneaded material.
