[origin: WO2020177934A1] The present invention relates to a method for preparing and storing an agent for treating keratinous material, in particular human hair, comprising the following steps: (1) mixing one or more organic C1-C6-alkoxy-silanes with water, (2) removing, partially or completely, C1-C6-alcohols, released due to the reaction in step (1), from the reaction mixture, (3) optionally adding one or more cosmetic components, (4) filling a packaging unit with the preparation and (5) storing the preparation in the packaging unit. The invention is characterised in that at least one of the steps (1), (2), (3), (4) and/or (5) takes place under an atmosphere which has a vapour content of less than 10 g/m3.
