The invention relates to organopolysiloxane-containing water-based compositions which are essentially free from organic solvents, have a flash point of more than 70 ° C. and, when diluted with water, essentially do not release any alcohols by hydrolysis.n n n The organopolysiloxane-containing compositions according to the invention can be obtained by mixing M moles of water-insoluble organotrialkoxysilanes with Q moles of water-soluble aminoalkylalkoxysilanes in the molar ratio 0 <M / Q ≦ 2 , Adding the mixture with water, adjusting the pH of the reaction mixture to a value between 1 and 8 and removing alcohol already present and / or during the reaction.n n n The process for the preparation of the organopolysiloxane-containing compositions according to the invention and the use thereof are also disclosed. |
