Abstract: The present invention relates to a process for the manufacturing of 3-phenylpropan-1-ol, from nature derived starting material, wherein said nature derived starting material comprises not less than 80 wt.% of cinnamaldehyde. In another aspect, the present invention relates to the process, which further comprises the steps: a) conversion of cinnamaldehyde as starting material to 3-phenylpropan-1-ol by a catalytic hydrogenation; b) optional purification of the 3-phenylpropan-1-ol by alkaline water extraction; c) distillation of 3-phenylpropan-1-ol. In a third aspect the present invention relates to use of 3-phenylpropan-1-ol obtained by the process of the invention in perfumes and/or personal care and/or cleaning products.

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: The invention relates to a temperature-stable solution consisting of a) 0.1-10% by weight of at least one hexamidine salt, b) 40-95% by weight of an alkanediol having a C3 to C5 carbon chain and a C log P of ?0.2 to ?1.1, c) 5-60% by weight of water and d) one or more additives to adjust the pH of the solution to 3.0 to 6.0 inclusive, wherein the total amount of components a) to d) is 100% by weight.
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.
