Abstract: A cognitive function evaluation device includes: an obtainment unit that obtains utterance data indicating a voice of an evaluatee uttering a sentence as instructed; a calculation unit that calculates, from the utterance data obtained by the obtainment unit, a feature based on the utterance data; an evaluation unit that compares the feature calculated by the calculation unit to reference data indicating a relationship between voice data indicating a voice of a person and a cognitive function of the person to evaluate the cognitive function of the evaluatee; and an output unit that outputs the sentence to be uttered by the evaluatee and outputs a result of evaluation by the evaluation unit.

Abstract: There is disclosed a toothpaste composition containing: (1) a water-soluble bactericide selected from the group consisting of pyridinium compounds, quaternary ammonium compounds and biguanide compounds in an amount of 0.001% to 5.0% by weight, based on the total weight of the composition; (2) a cationically-modified hydroxyethylcellulose having an average molecular weight of 1,000,000 or higher in the hydroxyethylcellulose portion thereof and having a cationization degree of 0.05 to 0.5 mol/glucose in an amount of 0.5% to 5.0% by weight, based on the total weight of the composition; (3) a surfactant selected from the group consisting of polyoxyethylene polyoxypropylene block copolymers and alkylolamide compounds in an amount of 0.5% to 13% by weight, based on the total weight of the composition; and (4) a polishing agent of the non-silica type in an amount of 5% to 50% by weight, based on the total weight of the composition.
