A method for condensation and gelation of aqueous solutions, emulsions and suspensionsdistinctive in that the substance to be condensed is mixed with aqueous dispersion containing 1 to 20% by weight of reticulated, dissoluble polymer or copolymer of acrylic acid and/or acryl amide, possibly in combination with other vinyl monomers, 0.1 to 20% by weight of mineral or organic acid and 0 to 20% by weight of modifying substances to improve the agent's stability of dispersion and facilitate its even distribution; next, the whole mixture is brought to the level of pH=6-12, preferably 7-9, with 0.5-20% by weight of aqueous dispersion in reference to the mass of the condensed solution, emulsion or suspension.
