Abstract:
Water-dispersible core-shell microcapsules that are essentially free of formaldehyde. Also, oligomeric compositions of, and microcapsules obtained from, particular reaction products between a polyamine component and a particular mixture of glyoxal and a C4-6 2,2-dialkoxy-ethanal. These compositions and microcapsules can be used as part of a perfuming composition or of a perfumed consumer product.
