Abstract: It is an object of the present disclosure to provide an agent for coloring keratinous material, in particular human hair, comprising (a1) at least one linear amino-functionalized silicone polymer, and (a2) at least one pigment, and (a3) at least one polysaccharide, exemplified in that the agent is free of silicone resins. A second subject matter is a method for dyeing keratin material, wherein the agent is applied to the keratin material.

Abstract: A glass powder or a glass-ceramic powder is provided that includes multicomponent glasses with at least three elements, where the glass powder or a glass-ceramic powder has a mean particle size of less than 1 ?m. In some embodiments, the mean particle size is less than 0.1 ?m, while in other embodiments the mean particle size is less than 10 nm.

Abstract: The method of preserving a perishable cosmetic and/or pharmaceutical preparation includes adding bioactive glass particles to the preparation, preferably in amounts up to 10 percent by weight. The bioactive glass particles preferably have particle sizes (d50) less than or equal to 10 ?m and contain from 40 to 60 wt. % SiO2, 10 to 30 wt. % CaO, 10 to 35 wt. % Na2O, 2 to 8 wt. % P2O5, 0 to 25 wt. % CaF2, 0 to 10 wt. % B2O3, 0 to 8 wt. % K2O and/or 0 to 5 wt. % MgO. A liquid cosmetic preparation with alcohol content insufficient for preservation is preserved in an inconspicuous manner by adding bioactive glass particles with particle sizes less than or equal to 10 ?m and with a refractive index close enough to that of the liquid cosmetic preparation so that bioactive glass particles are substantially invisible to an observer.

Abstract: The invention relates to a use of glass compositions having an antimicrobial and/or disinfectant effect in materials used for restoring teeth, excluding implants.

Abstract: The dental filling material for a permanent dental filling contains up to 87 percent by weight of a mixture of bioactive glass particles capable of forming a hydroxylapatite layer and conventional non-bioactive dental glass particles surrounded or embedded in a matrix material. The glass particles have an average particle size (d50) less than 50 ?m. When the index of refraction of the glass particles at least approximately matches the index of refraction of the matrix material a particularly attractive appearance results when the resulting filling material is used to make a dental filling. When the bioactive glass particles contain fluoride, protection against further caries is provided. The invention also includes a method of making the dental filling material, the dental filling made with it and a binder for binding the dental filling to a tooth.

Abstract: The invention relates to the use of a mixture of bioactive glass and dental glass for producing an agent for a permanent dental filling. The bioactive glass is preferably contained in a binding agent for binding a dental filling to a tooth, in a glass-ionomer cement, in a glass-plastic composite, in a composite-reinforced glass-ionomer cement and/or in an agent for treating the tooth root, the neck of the tooth and/or the tooth crown and preferably contains fluoride ions.

Abstract: The invention relates to a glass powder, where at least one oxidizing agent or one reducing agent is added to the glass powder. The glass powder is preferably used as dental glass powder.

Abstract: The invention relates to a barium-free, X-ray-opaque dental glass, to a dental glass/polymer composite comprising the glass, and to the use thereof as dental filling, where the dental glass has the following composition (in % by weight): SiO2 20-45, Al2O3 5-35, B2O3 1-10, Na2O 1-10, K2O 0-8, Cs2O 0-8, sum all alkali metal oxides 1-15, CaO 0-8, SrO 0-27, ZnO 2-20, ZrO2 2-10, P2O5 0-10, La2O3 0-10, F 2-20, the total content of B2O3, ZnO, ZrO2 and La2O3 is >20% by weight, and the refractive index nd of the dental glass is in the range from 1.47 to 1.70.
