What is described are sporicidal compositions, in which hydrogen peroxide and at least one radical stabilizer are homogeneously dissolved in a methacrylate monomer or a mixture of methacrylate monomers, and the quantitative ratio of radical stabilizer to hydrogen peroxide is larger than or equal to 1 to 1. The sporicidal monomer/monomer mixture is usually used for producing single component bone cement pastes; two-component bone cement pastes or monomer solutions for polymethylmethacrylate bone cements that are based on cement powder and monomer liquid. Moreover, a sporicidal cement paste having the following components is proposed: hydrogen peroxide and/or a hydrogen peroxide-releasing substance or mixture of substances; radical stabilizer; low-molecular liquid methacrylate; linear or branched polymethylmethacrylate or linear or branched methylmethacrylate co-polymer; cross-linked polymethylmethacrylate or cross-linked methylmethacrylate copolymer; as well as at least one component of a radical initiator system.
