Abstract: The current invention relates to a stabilized perfumed aqueous composition comprising: a) 95.1 to 99.9 wt. % of a component (A), wherein said component (A) is a perfume component in a concentration of at most 30 wt. % in water; b) 0.1 to 4.9 wt. % of a component (B), wherein said component (B) is 1,2-pentanediol. In another aspect, the invention relates to a process for stabilizing a perfumed aqueous composition by addition 0.1 to 4.9 wt. % of 1,2-pentanediol to said perfumed aqueous composition, wherein said perfumed aqueous composition is a composition comprising at most 30 wt. % of a perfume component in water. In a third aspect, the invention relates to the use of stabilized perfumed aqueous composition in cosmetics, personal care and cleaning products.

Abstract: A method for polymerizing 1,4-dioxane-2,5-diones in the presence of a generally protic initiator and at least one catalyst including at least one metal-free organic compound. The latter is a non-metal organic catalyst most often selected from among pyridines of which DMAP is a derivative, sulfonic acids, polycyclic tertiary amines, phosphazenes, thioureas, thioureas/amines, and guanidines. The invention also relates to polymers obtained by the method.
