FIELD: production of paper, cardboard.
SUBSTANCE: composition containing a cationogenic surfactant which contains a primary or secondary ammonium head group and a linear unsubstituted C12-alkyl tail group, is used to stimulate germination of bacterial endospores in pulp suspension for making paper, cardboard, etc. Disclosed composition is used in a method for quantitative reduction of bacterial endospores in pulp suspension for making paper, cardboard, etc. Method involves preparing an aqueous suspension of pulp and introducing said composition into a pulp suspension. Cationogenic surfactant is allowed to react with bacterial endospores in pulp suspension. Thus, stimulation of endospores and destruction of microorganisms is stimulated.
EFFECT: proposed invention makes it possible to produce hygienic paper or cardboard from pulp-containing suspension.
