Protection for obtaining microcapsules with average diameters in the range of 0.0001 to 0.5 mm, in which (a) aqueous preparations of active product with oleaginous bodies are prepared in the presence of emulsifiers to give O / W emulsions, (b) the emulsions obtained in this way are treated with aqueous solutions of anionic polymers, (c) the matrix thus obtained is contacted with aqueous solutions of cationic non-biological polymers, and (d) if appropriate, the encapsulation products obtained are separated. thus of the aqueous phase. |
