    摘要: A gel capsule, loaded with at least one organic percarboxylic acid is manufactured by the process comprising the steps of: (a) providing an oil having a melting point below 35° C. at atmospheric pressure and that is inert towards the organic percarboxylic acid; (b) contacting the oil with at least one stabilizer at a temperature of from 25° C. to 50° C. to obtain a liquid matrix medium comprising the oil and the stabilizer, (c) optionally cooling the matrix medium resulting from step (b) to a temperature above the gel-formation temperature of the matrix medium; (d) incorporating at least one organic percarboxylic acid in the form of solid particles into the liquid matrix medium obtained in step (b) to form a dispersion of the solid percarboxylic acid in the liquid matrix medium; (e) contacting the matrix medium obtained in process step (d), with a dispersion agent at a temperature below the gel-formation temperature to form gel capsules, wherein the organic percarboxylic acid is incorporated in an oil/stabilizer-gel matrix.
