摘要

The invention relates to micro capsules having an average diameter in the region of 0.0001 0.5 mm, obtained according to said methods by; (a) treating aqueous active ingredient preparations with oil bodies in the presence of emulsifiers to form O/W-emulsions; (b) the emulsions thus obtained are treated with aqueous solutions of anionic polymers; (c) the matrix thus obtained is brought into contact with aqueous solutions of non-biological cationic polymers and; (d) optionally, encapsulation products thus obtained are separated from the aqueous phase.
