Abstract
Suggested are polyurea microcapsules obtainable or obtained by reacting di- and/or polyisocyanates and guanidine carbonate in the presence of chemically modified biopolymer colloidal protection agents. The capsules can be loaded for example with fragrances and show high resistance against agglomeration in unstructured (viscosity 10-300 cps), anionic surfactant based liquid products.
