摘要： A protective polysaccharide film containing a buffering agent in an amount which is effective for substantially resisting pH changes due to environmental influence; a solution for the application onto a surface to be protected, comprising: a) a polysaccharide dissolved in an aqueous solvent therefore; and b) a buffering agent, said solution being capable of forming a film on said surface which on swelling or dissolution maintains a substantially constant pH due to environmental influence; and a process for protecting a surface from non-desired contamination and to facilitate the removal of such contamination from said surface, comprising the steps: a) applying a solution according to any of claims 7 to 12 on said surface before being subjected to contamination; b) allowing the applied solution to dry with the formation of a solid film on said surface, said film being capable of substantially resisting pH changes due to environmental influence; c) treating said film with a liquid capable of redissolving the film or providing swelling thereof; and d) removing the undesired contamination by completely or partially removing said film from the surface.

摘要： A process for facilitating the removal of undesired contamination from a surface, comprising the steps: a) applying a solution containing a polysaccharide and a solvent therefor onto said surface before it is subjected to contamination, said polysaccharide being capable of forming a redissolvable or swelling solid film upon drying; b) allowing the applied solution to dry to form a solid film on said surface; c) treating the coated surface with a liquid capable of redissolving the film or providing for swelling thereof; and d) removing the undesired contamination by removing the dissolved or swelled surface layer of the film.

摘要： A process for protecting a surface from non-desired contamination and for facilitating removal of said contamination from said surface, characterized by the steps: a) preparing a solution of polysaccharides containing at least two components, wherein one component is constituted by a first polysaccharide which, when precipitated from a solution by evaporation of the solvent thereof, directly forms a film, and wherein the second component is constituted by a second polysaccharide which, when precipitated from a solution by evaporation of the solvent thereof, forms a film via at least partial gel formation, or by interaction with said first polysaccharide, said films being redissolvable or swellable; b) applying the solution from step a) onto said surface before subjected to contamination; c) allowing the applied solution to dry so as to form a solid film on said surface via at least partial gel formation; d) treating the film-coated surface with a liquid capable of redissolving film or provided swelling thereof; and e) removing the non-desired contamination by complete or partial removal of the film from the surface.

摘要： A polysaccharide-based composition, characterized by comprising or essentially consisting of: at least a first component a) excluding galactans constituted by a substituted beta-1,4-linked glycan which is dissolvable in water of a certain temperature and which has a molecular weight (Mw) of 5.104 Daltons, preferably 105 Daltons, particularly 106 Daltons, and at least a second component b), also excluding galactans, constituted by a substituted beta-1,4-linked glycan which is more difficult to dissolve than said first component at said temperature, or is agar or a carrageenan; the use of the composition above as a: a) means for reducing friction, b) means for facilitating removal of undesired contamination from surfaces, such as graffiti, scrawl, soot, etc., c) means for preserving moisture, d) protective surface coverage, e) packaging material, f) slow release matrix or coating for drugs; a body in solid phase having a surface intended for contact with a liquid and for relative movement between surface and liquid, said surface being coated with a solid film essentially consisting of such a composition; and a method for the removal of undesired contamination on a surface.
